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 {@link DataObject::$extensions} or {@link Object::add_extension()}.
Invoke extension point. This will prefer explicit extend
prefixed
methods.
Edit the given query object to support queries for this extension
Ensures that there is always a 404 page by checking if there's an instance of ErrorPage with a 404 and 500 error code. If there is not, one is created when the DB is built.
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. {@link DataObject->getCMSFields()}.
This function is used to provide modifications to the form used for front end forms. {@link DataObject->getFrontEndFields()}
This is used to provide modifications to the form actions used in the CMS. {@link 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']
Extension point in see DataObject::fieldLabels
No description
Default records are allowed by default override on model if needed
No description
Get a {@link HTTPResponse} to response to a HTTP error code if an {@link ErrorPage} for that code is present. First tries to serve it through the standard SilverStripe request method. Falls back to a static file generated when the user hit's save and publish in the CMS
Returns statically cached content for a given error code
Write out the published version of the page to the filesystem.
Determine if static content is cached for this page
No description
