FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package silverstripe-auto-delete
Silverstripe Auto-Delete
EXPERIMENTAL!!!
An extension to add functionality to DataObjects to:
- Delete unused
$has_onerelationships when the$has_onechanges (eg: a new file is uploaded). This functionality will not run directly from anyVersionedDataObjects. - Delete unused
$has_one&$has_manyrelationships when a DataObject is deleted.
The extension will only delete objects if they are not in use elsewhere.
All DataObjects get two additional new functions which you can integrate into other things:
inUse()- used to detect whether an object is in use somewhere. Note: It only detects if it is used from non-versioned and published relationships. Draft & modified states are not detected!deleteIfUnused()- used to delete a DataObject if not in use somewhere. If the object being deleted has adeleteFile()method, then that will be run too (ie: file deletion).
Usage
In your defined DataObject, add a private static $auto_delete = [....]; variable, defining which related $has_one and $has_many DataObjects to automatically delete, for example:
This will automatically delete the Image (if unused elsewhere) if the Slide is deleted, or delete the original Image if a new Image is uploaded.
Notes
Auto-delete cannot recursively delete a $has_many objects, as it will only delete if the object is no longer linked to any other DataObject. If you wish to recursively delete objects then you should do that manually via onBeforeDelete() or 'onAfterDelete().
