abstract class ModelAdmin extends LeftAndMain (View source)

Generates a three-pane UI for editing model classes, tabular results and edit forms.

Relies on data such as {@link DataObject::$db} and {@link DataObject::getCMSFields()} to scaffold interfaces "out of the box", while at the same time providing flexibility to customize the default output.

mixed __call(string $method, array $arguments)

Attempts to locate and call a method dynamically added to a class at runtime if a default cannot be located

You can add extra methods to a class using {@link Extensions}, {@link Object::createMethod()} or {@link Object::addWrapperMethod()}

Parameters

string $method
array $arguments

Return Value

mixed

Exceptions

BadMethodCallException

bool hasMethod(string $method)

Return TRUE if a method exists on this object

This should be used rather than PHP's inbuild method_exists() as it takes into account methods added via extensions

Parameters

string $method

Return Value

bool

array allMethodNames(bool $custom = false)

Return the names of all the methods available on this object

Parameters

bool $custom

include methods added dynamically at runtime

Return Value

array

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 {@link Object::$extensions} array. See {@link SiteTree::$extensions} for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through {@link singleton()}).

Parameters

string $classOrExtension

Class that should be extended - has to be a subclass of {@link Object}

string $extension

Subclass of {@link 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 {@link Object} instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through {@link singleton()} to avoid side-effects from stale extension information.

Parameters

string $extension

class name of an {@link Extension} subclass, without parameters

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

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 {@link 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 {@link 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 {@link __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 {@link $extension_instances}. Extension instances are initialized at constructor time, meaning if you use {@link add_extension()} afterwards, the added extension will just be added to new instances of the extended class. Use the static method {@link 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 {@link Extension} subclass without parameters

Return Value

bool

Extension[] getExtensionInstances()

Get all extension instances for this specific object instance.

See {@link 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 {@link DataExtension} instances, keyed by classname.

static Injectable create(array ...$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'); $list = SiteTree::get();

Parameters

array ...$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

static Config_ForClass config()

Find appropriate templates for SSViewer to use to render this object

Parameters

string $suffix

Return Value

array

ViewableData Me()

When rendering some objects it is necessary to iterate over the object being rendered, to do this, you need access to itself.

ViewableData

string ThemeDir() deprecated

deprecated 4.0.0:5.0.0 Use $resourcePath or $resourceURL template helpers instead

Return the directory if the current active theme (relative to the site root).

This method is useful for things such as accessing theme images from your template without hardcoding the theme page - e.g. .

This method should only be used when a theme is currently active. However, it will fall over to the current project directory.

Return Value

string

URL to the current theme

string CSSClasses(string $stopAtClass = self::class)

Get part of the current classes ancestry to be used as a CSS class.

HTTPResponse|RequestHandler|string|array handleRequest(HTTPRequest $request)

Executes this controller, and return an {@link HTTPResponse} object with the result.

This method defers to {@link RequestHandler->handleRequest()} to determine which action should be executed

Note: You should rarely need to overload handleRequest() - this kind of change is only really appropriate for things like nested controllers - {@link ModelAsController} and {@link RootURLController} are two examples here. If you want to make more orthodox functionality, it's better to overload {@link init()} or {@link index()}.

Important: If you are going to overload handleRequest, make sure that you start the method with $this->beforeHandleRequest() and end the method with $this->afterHandleRequest()

Parameters

HTTPRequest $request

The object that is reponsible for distributing URL parsing

Return Value

HTTPResponse|RequestHandler|string|array

array|null allowedActions(string $limitToClass = null)

Get a array of allowed actions defined on this controller, any parent classes or extensions.

Caution: Since 3.1, allowed_actions definitions only apply to methods on the controller they're defined on, so it is recommended to use the $class argument when invoking this method.

Parameters

string $limitToClass

Return Value

array|null

bool hasAction(string $action)

Parameters

string $action

Return Value

bool

bool checkAccessAction(string $action)

Check that the given action is allowed to be called from a URL.

It will interrogate {@link self::$allowed_actions} to determine this.

Parameters

string $action

Return Value

bool

Exceptions

Exception

httpError(int $errorCode, string $errorMessage = null)

Throws a HTTP error response encased in a {@link HTTPResponse_Exception}, which is later caught in {@link RequestHandler::handleAction()} and returned to the user.

Parameters

int $errorCode
string $errorMessage

Plaintext error message

Exceptions

HTTPResponse_Exception

HTTPRequest getRequest()

Returns the HTTPRequest object that this controller is using.

Returns a placeholder {@link NullHTTPRequest} object unless {@link handleAction()} or {@link handleRequest()} have been called, which adds a reference to an actual {@link HTTPRequest} object.

Return Value

HTTPRequest

$this setRequest(HTTPRequest $request)

Typically the request is set through {@link handleAction()} or {@link handleRequest()}, but in some based we want to set it manually.

Parameters

HTTPRequest $request

Return Value

$this

Overrides {@link \SilverStripe\Admin\LeftAndMain} to ensure the active model class (the DataObject we are currently viewing) is included in the URL.

Parameters

string $action

Optional action

Return Value

string

HTTPResponse redirect(string $url, int $code = 302)

Overloaded redirection logic to trigger a fake redirect on ajax requests.

While this violates HTTP principles, its the only way to work around the fact that browsers handle HTTP redirects opaquely, no intervention via JS is possible. In isolation, that's not a problem - but combined with history.pushState() it means we would request the same redirection URL twice if we want to update the URL as well. See LeftAndMain.js for the required jQuery ajaxComplete handlers.

Parameters

string $url
int $code

Return Value

HTTPResponse

string getBackURL()

Safely get the value of the BackURL param, if provided via querystring / posted var

Return Value

string

string getReferer()

Get referer

Return Value

string

HTTPResponse redirectBack()

Redirect back. Uses either the HTTP-Referer or a manually set request-variable called "BackURL".

This variable is needed in scenarios where HTTP-Referer is not sent (e.g when calling a page by location.href in IE). If none of the two variables is available, it will redirect to the base URL (see {@link Director::baseURL()}).

Return Value

HTTPResponse

doInit()

A stand in function to protect the init function from failing to be called as well as providing before and after hooks for the init function itself

This should be called on all controllers before handling requests

$this setURLParams(array $urlParams)

Parameters

array $urlParams

Return Value

$this

array getURLParams()

Returns the parameters extracted from the URL by the {@link Director}.

Return Value

array

Note: Ensure this controller is assigned a request with a valid session before pushing it to the stack.

popCurrent()

Pop this controller off the top of the stack.

null|string redirectedTo()

Tests whether a redirection has been requested. If redirect() has been called, it will return the URL redirected to. Otherwise, it will return null.

Form EditForm(HTTPRequest $request = null)

Retrieves an edit form, either for display, or to process submitted data.

Also used in the template rendered through {@link Right()} in the $EditForm placeholder.

This is a "pseudo-abstract" methoed, usually connected to a {@link getEditForm()} method in an entwine subclass. This method can accept a record identifier, selected either in custom logic, or through {@link currentPageID()}. The form usually construct itself from {@link DataObject->getCMSFields()} for the specific managed subclass defined in {@link LeftAndMain::$tree_class}.

Parameters

HTTPRequest $request

Passed if executing a HTTPRequest directly on the form. If empty, this is invoked as $EditForm in the template

Return Value

Form

Should return a form regardless wether a record has been found. Form might be readonly if the current user doesn't have the permission to edit the record.

Form getEditForm(int $id = null, FieldList $fields = null)

Produces an edit form that includes a default {@link \SilverStripe\Forms\GridField\GridField} for the currently active {@link \SilverStripe\ORM\DataObject}. The GridField will show data from the currently active modelClass only (see {@link self::init()}).

Parameters

int $id
FieldList $fields

Return Value

Form

Form EmptyForm()

string Tools()

Renders a panel containing tools which apply to all displayed "content" (mostly through {@link EditForm()}), for example a tree navigation or a filter panel.

Auto-detects applicable templates by naming convention: "_Tools.ss", and takes the most specific template (see {@link getTemplatesWithSuffix()}). To explicitly disable the panel in the subclass, simply create a more specific, empty template.

Return Value

string

HTML

string EditFormTools()

Renders a panel containing tools which apply to the currently displayed edit form.

The main difference to {@link Tools()} is that the panel is displayed within the element structure of the form panel (rendered through {@link EditForm}). This means the panel will be loaded alongside new forms, and refreshed upon save, which can mean a performance hit, depending on how complex your panel logic gets. Any form fields contained in the returned markup will also be submitted with the main form, which might be desired depending on the implementation details.

Return Value

string

HTML

batchactions()

Return Value

int

setCurrentPageID(int $id)

Forces the current page to be set in session, which can be retrieved later through {@link currentPageID()}.

Keep in mind that setting an ID through GET/POST or as a URL parameter will overrule this value.

Parameters

DataList getList()

You can override how ModelAdmin returns DataObjects by either overloading this method, or defining an extension to ModelAdmin that implements the updateList method (and takes a {@link \SilverStripe\ORM\DataList} as the first argument).

For example, you might want to do this if this particular ModelAdmin should only ever show objects where an Archived flag is set to false. That would be best done as an extension, for example:

public function updateList(\SilverStripe\ORM\DataList $list) { return $list->filter('Archived', false); }
