Extending existing ModelAdmin
Sometimes you'll work with ModelAdmins from other modules. To customise these interfaces, you can always subclass. But there's also another tool at your disposal: The [api:Extension] API.
:::php
class MyAdminExtension extends Extension {
// ...
public function updateEditForm(&$form) {
$form->Fields()->push(/* ... */)
}
}
Now enable this extension through your [config.yml](/topics/configuration)
file.
:::yml
MyAdmin:
extensions:
- MyAdminExtension
The following extension points are available: updateEditForm()
, updateSearchContext()
,
updateSearchForm()
, updateList()
, updateImportForm
.
