Traits

Allows an object to have extensions applied to it.

A class that can be instantiated or replaced via DI

Provides extensions to this object to integrate it with standard config API methods.

Allows an object to declare a set of custom methods

Constants

CHANGE_NONE

Represents a field that hasn't changed (before === after, thus before == after)

CHANGE_STRICT

Represents a field that has changed type, although not the loosely defined value.

(before !== after && before == after) E.g. change 1 to true or "true" to true, but not true to 0. Value changes are by nature also considered strict changes.

CHANGE_VALUE

Represents a field that has changed the loosely defined value (before != after, thus, before !== after)) E.g. change false to true, but not false to 0

CREATE_OBJECT

Value for 2nd argument to constructor, indicating that a new record is being created Setters will be called on fields passed, and defaults will be populated

CREATE_SINGLETON

Value for 2nd argument to constructor, indicating that a record is a singleton representing the whole type, e.g. to call requireTable() in dev/build Defaults will not be populated and data passed will be ignored

CREATE_HYDRATED

Value for 2nd argument to constructor, indicating that a record is being hydrated from the database Setter methods are not called, and population via private static $defaults will not occur.

CREATE_MEMORY_HYDRATED

Value for 2nd argument to constructor, indicating that a record is being hydrated from memory. This can be used to initialised a record that doesn't yet have an ID. Setter methods are not called, and population via private static $defaults will not occur.

protected registerExtraMethodCallback(string $name, callable $callback)

Register an callback to invoke that defines extra methods

Parameters

string $name

protected constructExtensions() deprecated

deprecated 4.0.0:5.0.0 Extensions and methods are now lazy-loaded

No description

protected defineExtensionMethods()

Adds any methods from Extension instances attached to this object.

All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().

static bool add_extension(string $classOrExtension, string $extension = null)

Add an extension to a specific class.

The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.

As an alternative, extensions can be added to a specific class directly in the Object::$extensions array. See SiteTree::$extensions for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through singleton()).

Parameters

string $classOrExtension

Class that should be extended - has to be a subclass of Object

string $extension

Subclass of Extension with optional parameters as a string, e.g. "Versioned" or "Translatable('Param')"

Return Value

bool

Flag if the extension was added

See also

http://doc.silverstripe.org/framework/en/trunk/reference/dataextension

static remove_extension(string $extension)

Remove an extension from a class.

Note: This will not remove extensions from parent classes, and must be called directly on the class assigned the extension.

Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any Object instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through singleton() to avoid side-effects from stale extension information.

Add support for removing extensions with parameters

Parameters

string $extension

class name of an Extension subclass, without parameters

static array get_extensions(string $class = null, bool $includeArgumentString = false)

No description

Parameters

string $class

If omitted, will get extensions for the current class

bool $includeArgumentString

Include the argument string in the return array, FALSE would return array("Versioned"), TRUE returns array("Versioned('Stage','Live')").

Return Value

array

Numeric array of either DataExtension class names, or eval'ed class name strings with constructor arguments.

static array|null get_extra_config_sources(string $class = null)

Get extra config sources for this class

Parameters

string $class

Name of class. If left null will return for the current class

Return Value

array|null

static bool has_extension(string $classOrExtension, string $requiredExtension = null, bool $strict = false)

Return TRUE if a class has a specified extension.

This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))

Parameters

string $classOrExtension

Class to check extension for, or the extension name to check if the second argument is null.

string $requiredExtension

If the first argument is the parent class, this is the extension to check. If left null, the first parameter will be treated as the extension.

bool $strict

if the extension has to match the required extension and not be a subclass

Return Value

bool

Flag if the extension exists

array invokeWithExtensions(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)

Calls a method if available on both this object and all applied Extensions, and then attempts to merge all results into an array

Parameters

string $method

the method name to call

mixed $a1
mixed $a2
mixed $a3
mixed $a4
mixed $a5
mixed $a6
mixed $a7

Return Value

array

List of results with nulls filtered out

array extend(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)

Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed

Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.

The extension methods are defined during __construct()} in {@link defineMethods().

Parameters

string $method

the name of the method to call on each extension

mixed $a1
mixed $a2
mixed $a3
mixed $a4
mixed $a5
mixed $a6
mixed $a7

Return Value

array

Extension|null getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

Extension|null

bool hasExtension(string $extension)

Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.

Caution: Don't use singleton()->hasExtension() as it will give you inconsistent results based on when the singleton was first accessed.

Parameters

string $extension

Classname of an Extension subclass without parameters

Return Value

bool

Extension[] getExtensionInstances()

Get all extension instances for this specific object instance.

See get_extensions() to get all applied extension classes for this class (not the instance).

This method also provides lazy-population of the extension_instances property.

Return Value

Extension[]

Map of DataExtension instances, keyed by classname.

static Injectable create(mixed ...$args)

An implementation of the factory method, allows you to create an instance of a class

This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.

This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();

Parameters

mixed ...$args

Return Value

Injectable

static Injectable singleton(string $class = null)

Creates a class instance by the "singleton" design pattern.

It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

Parameters

string $class

Optional classname to create, if the called class should not be used

Return Value

Injectable

The singleton instance

Return Value

string

string getClassName()

Gets name of this class

Return Value

string

$this setClassName(string $className)

Set the ClassName attribute. $class is also updated.

Warning: This will produce an inconsistent record, as the object instance will not automatically switch to the new subclass. Please use newClassInstance() for this purpose, or destroy and reinstanciate the record.

Parameters

string $className

The new ClassName attribute (a subclass of DataObject)

Return Value

$this

DataObject newClassInstance(string $newClassName)

Create a new instance of a different class from this object's record.

This is useful when dynamically changing the type of an instance. Specifically, it ensures that the instance of the class is a match for the className of the record. Don't set the DataObject->class} or {@link DataObject->ClassName property manually before calling this method, as it will confuse change detection.

If the new class is different to the original class, defaults are populated again because this will only occur automatically on instantiation of a DataObject if there is no record, or the record has no ID. In this case, we do have an ID but we still need to repopulate the defaults.

Parameters

string $newClassName

The name of the new class

Return Value

DataObject

The new instance of the new class, The exact type will be of the class name provided.

Return Value

string

User friendly singular name of this DataObject

string i18n_singular_name()

Get the translated user friendly singular name of this DataObject same as singular_name() but runs it through the translating function

Translating string is in the form: $this->class.SINGULARNAME Example: Page.SINGULARNAME

Return Value

string

User friendly translated singular name of this DataObject

string plural_name()

Get the user friendly plural name of this DataObject If the name is not defined (by renaming $plural_name in the subclass), this returns a pluralised version of the class name.

Return Value

string

User friendly plural name of this DataObject

string i18n_plural_name()

Get the translated user friendly plural name of this DataObject Same as plural_name but runs it through the translation function Translation string is in the form: $this->class.PLURALNAME Example: Page.PLURALNAME

Return Value

string

User friendly translated plural name of this DataObject

string getTitle()

Standard implementation of a title/label for a specific record. Tries to find properties 'Title' or 'Name', and falls back to the 'ID'. Useful to provide user-friendly identification of a record, e.g. in errormessages or UI-selections.

Overload this method to have a more specialized implementation, e.g. for an Address record this could be:

function getTitle() {
  return "{$this->StreetNumber} {$this->StreetName} {$this->City}";
}

Return Value

string

DataObject data()

Returns the associated database record - in this case, the object itself.

This is included so that you can call $dataOrController->data() and get a DataObject all the time.

Return Value

DataObject

Associated database record

array toMap()

Convert this object to a map.

Note that it has the following quirks:

  • custom getters, including those that adjust the result of database fields, won't be executed
  • NULL values won't be returned.

Return Value

array

The data as a map.

array getQueriedDatabaseFields()

Return all currently fetched database fields.

This function is similar to toMap() but doesn't trigger the lazy-loading of all unfetched fields. Obviously, this makes it a lot faster.

Return Value

array

The data as a map.

DataObject update(array $data)

Update a number of fields on this object, given a map of the desired changes.

The field names can be simple names, or you can use a dot syntax to access $has_one relations. For example, array("Author.FirstName" => "Jim") will set $this->Author()->FirstName to "Jim".

Doesn't write the main object, but if you use the dot syntax, it will write() the related objects that it alters.

When using this method with user supplied data, it's very important to whitelist the allowed keys.

Parameters

array $data

A map of field name to data values to update.

Return Value

DataObject $this

DataObject castedUpdate(array $data)

Pass changes as a map, and try to get automatic casting for these fields.

Doesn't write to the database. To write the data, use the write() method.

Parameters

array $data

A map of field name to data values to update.

Return Value

DataObject $this

bool merge(DataObject $rightObj, string $priority = 'right', bool $includeRelations = true, bool $overwriteWithEmpty = false)

Merges data and relations from another object of same class, without conflict resolution. Allows to specify which dataset takes priority in case its not empty.

has_one-relations are just transferred with priority 'right'. has_many and many_many-relations are added regardless of priority.

Caution: has_many/many_many relations are moved rather than duplicated, meaning they are not connected to the merged object any longer. Caution: Just saves updated has_many/many_many relations to the database, doesn't write the updated object itself (just writes the object-properties). Caution: Does not delete the merged object. Caution: Does now overwrite Created date on the original object.

Parameters

DataObject $rightObj
string $priority

left|right Determines who wins in case of a conflict (optional)

bool $includeRelations

Merge any existing relations (optional)

bool $overwriteWithEmpty

Overwrite existing left values with empty right values. Only applicable with $priority='right'. (optional)

Return Value

bool

$this forceChange()

Forces the record to think that all its data has changed.

Doesn't write to the database. Force-change preserved until next write. Existing CHANGE_VALUE or CHANGE_STRICT values are preserved.

Return Value

$this

ValidationResult validate()

Validate the current object.

By default, there is no validation - objects are always valid! However, you can overload this method in your DataObject sub-classes to specify custom validation, or use the hook through DataExtension.

Invalid objects won't be able to be written - a warning will be thrown and no write will occur. onBeforeWrite() and onAfterWrite() won't get called either.

It is expected that you call validate() in your own application to test that an object is valid before attempting a write, and respond appropriately if it isn't.

Return Value

ValidationResult

See also

{@link ValidationResult}

ValidationResult doValidate() deprecated

deprecated 4.12.0 Use validate() instead

Public accessor for {DataObject::validate()}

Return Value

ValidationResult

onBeforeWrite()

Event handler called before writing to the database.

You can overload this to clean up or otherwise process data before writing it to the database. Don't forget to call parent::onBeforeWrite(), though!

This called after $this->validate(), so you can be sure that your data is valid.

protected onAfterWrite()

Event handler called after writing to the database.

You can overload this to act upon changes made to the data after it is written. $this->changed will have a record database. Don't forget to call parent::onAfterWrite(), though!

ArrayList findCascadeDeletes(bool $recursive = true, ArrayList $list = null)

Find all objects that will be cascade deleted if this object is deleted

Notes:

  • If this object is versioned, objects will only be searched in the same stage as the given record.
  • This will only be useful prior to deletion, as post-deletion this record will no longer exist.

Parameters

bool $recursive

True if recursive

FieldList getCMSFields()

Centerpiece of every data administration interface in Silverstripe, which returns a FieldList} suitable for a {@link Form object.

If not overloaded, we're using scaffoldFormFields() to automatically generate this set. To customize, overload this method in a subclass or extended onto it by using DataExtension->updateCMSFields().

class MyCustomClass extends DataObject {
 static $db = array('CustomProperty'=>'Boolean');

 function getCMSFields() {
   $fields = parent::getCMSFields();
   $fields->addFieldToTab('Root.Content',new CheckboxField('CustomProperty'));
   return $fields;
 }
}

Return Value

FieldList

Returns a TabSet for usage within the CMS - don't use for frontend forms.

FieldList getCMSActions()

need to be overload by solid dataobject, so that the customised actions of that dataobject, including that dataobject's extensions customised actions could be added to the EditForm.

Return Value

FieldList

an Empty FieldList(); need to be overload by solid subclass

CompositeValidator getCMSCompositeValidator()

When extending this class and overriding this method, you will need to instantiate the CompositeValidator by calling parent::getCMSCompositeValidator(). This will ensure that the appropriate extension point is also invoked.

You can also update the CompositeValidator by creating an Extension and implementing the updateCMSCompositeValidator(CompositeValidator $compositeValidator) method.

Return Value

CompositeValidator

See also

CompositeValidator for examples of implementation

FieldList getFrontEndFields(array $params = null)

Used for simple frontend forms without relation editing or TabSet} behaviour. Uses {@link scaffoldFormFields() by default. To customize, either overload this method in your subclass, or extend it by DataExtension->updateFrontEndFields().

Decide on naming for "website|frontend|site|page" and stick with it in the API

array getChangedFields(bool|array $databaseFieldsOnly = false, int $changeLevel = self::CHANGE_STRICT)

Return the fields that have changed since the last write.

The change level affects what the functions defines as "changed":

  • Level CHANGE_STRICT (integer 1) will return strict changes, even !== ones.
  • Level CHANGE_VALUE (integer 2) is more lenient, it will only return real data changes, for example a change from 0 to null would not be included.

Example return:

array(
  'Title' = array('before' => 'Home', 'after' => 'Home-Changed', 'level' => DataObject::CHANGE_VALUE)
)

Parameters

bool|array $databaseFieldsOnly

Filter to determine which fields to return. Set to true to return all database fields, or an array for an explicit filter. false returns all fields.

int $changeLevel

int $changeLevel

See getChangedFields()

Return Value

bool

$this setCastedField(string $fieldName, mixed $value)

Set the value of the field, using a casting object.

This is useful when you aren't sure that a date is in SQL format, for example. setCastedField() can also be used, by forms, to set related data. For example, uploaded images can be saved into the Image table.

Parameters

string $fieldName
mixed $value

New field value

Return Value

$this

bool hasDatabaseField(string $field)

Returns true if the given field exists as a database column

Parameters

string $field

array $context

Additional $context to pass to extendedCan()

Return Value

bool

True if the the member is allowed to do the given action

bool|null extendedCan(string $methodName, Member|int $member, array $context = [])

  • false: Disallow this permission, regardless of what other extensions say
    • true: Allow this permission, as long as no other extensions return false
    • NULL: Don't affect the outcome

This method itself returns a tri-state value, and is designed to be used like this:

$extended = $this->extendedCan('canDoSomething', $member);
if ($extended !== null) return $extended;
else return $normalValue;

DBField dbObject(string $fieldName)

Return the DBField object that represents the given field.

This works similarly to obj() with 2 key differences:

  • it still returns an object even when the field has no value.
  • it only matches fields and not methods
  • it matches foreign keys generated by has_one relationships, eg, "ParentID"

Parameters

string $fieldName

Name of the field

Return Value

DBField

The field as a DBField object

mixed relObject(string $fieldPath)

Traverses to a DBField referenced by relationships between data objects.

The path to the related field is specified with dot separated syntax (eg: Parent.Child.Child.FieldName).

If a relation is blank, this will return null instead. If a relation name is invalid (e.g. non-relation on a parent) this can throw a LogicException.

Parameters

string $fieldPath

List of paths on this object. All items in this path must be ViewableData implementors

Return Value

mixed

DBField of the field on the object or a DataList instance.

Exceptions

LogicException

mixed relField(string $fieldName)

$containerClass is Ignored, why?

Parameters

string $callerClass

The class of objects to be returned

string|array $filter

A filter to be inserted into the WHERE clause. Supports parameterised queries. See SQLSelect::addWhere() for syntax examples.

string|array $sort

A sort expression to be inserted into the ORDER BY clause. If omitted, self::$default_sort will be used.

string $join

DataList

The objects matching the filter, in the class specified by $containerClass

static DataObject|null get_one(string $callerClass, string|array $filter = "", bool $cache = true, string $orderby = "")

Return the first item matching the given query.

The object returned is cached, unlike DataObject::get()->first() DataList::first() and DataObject::get()->last() DataList::last()

The filter argument supports parameterised queries (see SQLSelect::addWhere() for syntax examples). Because of that (and differently from e.g. DataList::filter()) you need to manually escape the field names:

$member = DataObject::get_one('Member', [ '"FirstName"' => 'John' ]);

Parameters

string $callerClass

The class of objects to be returned

string|array $filter

A filter to be inserted into the WHERE clause.

requireTable()

Check the database schema and update it as necessary.

requireDefaultRecords()

Add default records to database. This function is called whenever the database is built, after the database tables have all been created. Overload this to add default records when the database is built, but make sure you call parent::requireDefaultRecords().

onAfterBuild()

Invoked after every database build is complete (including after table creation and default record population).

See DatabaseAdmin::doBuild() for context.

array searchableFields()

Get the default searchable fields for this object, as defined in the $searchable_fields list. If searchable fields are not defined on the data object, uses a default selection of summary fields.

Return Value

array

array fieldLabels(bool $includerelations = true)

Get any user defined searchable fields labels that exist. Allows overriding of default field names in the form interface actually presented to the user.

The reason for keeping this separate from searchable_fields, which would be a logical place for this functionality, is to avoid bloating and complicating the configuration array. Currently much of this system is based on sensible defaults, and this property would generally only be set in the case of more complex relationships between data object being required in the search interface.

Generates labels based on name of the field itself, if no static property self::field_labels exists.

Parameters

bool $includerelations

a boolean value to indicate if the labels returned include relation fields

Return Value

array

Array of all element labels

string fieldLabel(string $name)

Get a human-readable label for a single field, see fieldLabels() for more details.

Parameters

string $name

Name of the field

Return Value

string

Label of the field

array summaryFields()

Get the default summary fields for this object.

Return Value

array

array defaultSearchFilters()

array

bool isInDB()

No description

Return Value

bool

True if the object is in the database

static disable_subclass_access()

array provideI18nEntities()

Returns the list of provided translations for this object.

Note: Pluralised forms are always returned in array format.

Example usage:

class MyTestClass implements i18nEntityProvider
{
  public function provideI18nEntities()
  {
    $entities = [];
    foreach($this->config()->get('my_static_array') as $key => $value) {
      $entities["MyTestClass.my_static_array_{$key}"] = $value;
    }
    $entities["MyTestClass.PLURALS"] = [
      'one' => 'A test class',
      'other' => '{count} test classes',
    ]
    return $entities;
  }
}

Example usage in DataObject->provideI18nEntities().

You can ask textcollector to add the provided entity to a different module. Simply wrap the returned value for any item in an array with the format: [ 'default' => $defaultValue, 'module' => $module ]

class MyTestClass implements i18nEntityProvider
{
  public function provideI18nEntities()
  {
    $entities = [
      'MyOtherModuleClass.MYENTITY' => [
        'default' => $value,
        'module' => 'myothermodule',
      ]
    ];
  }
  return $entities;
}
