AssetControlExtension
class AssetControlExtension extends DataExtension (View source)
This class provides the necessary business logic to ensure that any assets attached to a record are safely deleted, published, or protected during certain operations.
This class will respect the canView() of each object, and will use it to determine whether or not public users can access attached assets. Public and live records will have their assets promoted to the public store.
Assets which exist only on non-live stages will be protected.
Assets which are no longer referenced will be flushed via explicit delete calls to the underlying filesystem.
Properties
| DataObject|Versioned | $owner | A {\SilverStripe\ORM\DataObject}, potentially decorated with {\SilverStripe\Versioned\Versioned} extension. |
Methods
Called when this extension is added to a particular class
Temporarily modify the owner. The original owner is ensured to be restored
Clear the current owner, and restore extension to the state prior to the last setOwner()
Helper method to strip eval'ed arguments from a string that's passed to DataObject::$extensions or Object::add_extension().
Edit the given query object to support queries for this extension
Update the database schema as required by this extension.
Ensure that changes to records flush overwritten files, and update the visibility of other assets.
Ensure that deletes records remove their underlying file assets, without affecting other staged records.
Influence the owner's can() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.
Influence the owner's canEdit() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.
Influence the owner's canDelete() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.
Influence the owner's canCreate() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.
Define extra database fields
This function is used to provide modifications to the form in the CMS by the extension. By default, no changes are made. DataObject->getCMSFields().
This function is used to provide modifications to the Validators used on a DataObject.
This function is used to provide modifications to the form used for front end forms. DataObject->getFrontEndFields()
This is used to provide modifications to the form actions used in the CMS. DataObject->getCMSActions().
this function is used to provide modifications to the summary fields in CMS by the extension By default, the summaryField() of its owner will merge more fields defined in the extension's $extra_fields['summary_fields']
this function is used to provide modifications to the fields labels in CMS by the extension By default, the fieldLabels() of its owner will merge more fields defined in the extension's $extra_fields['field_labels']
Given a set of asset manipulations, trigger any necessary publish, protect, or delete actions on each asset.
Checks all stages other than the current stage, and check the visibility of assets attached to those records.
Given a record, add all assets it contains to the given manipulation.
Return a list of all tuples attached to this dataobject Note: Variants are excluded
Determine if {Versioned) extension rules should be applied to this object

updateCMSFields(FieldList $fields)
This function is used to provide modifications to the form in the CMS by the extension. By default, no changes are made. DataObject->getCMSFields().
Please consider using updateFormFields() to globally add formfields to the record. The method updateCMSFields() should just be used to add or modify tabs, or fields which are specific to the CMS-context.
