>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #1894210. --> Reported by: [sprocketman](https://www.drupal.org/user/572698) >>> <h2>Summary</h2> <p>This is a simple but powerful module for <em>Drupal 7</em> that allows administrators to effectively manage child entities when their parent entities are deleted. Upon parent entity deletion, it gives the option to either delete all dependent entities or drill down the tree of child entities and unselect any that you wish to maintain. The term "parent" and "child" depends on the set up. Some may prefer to set up their children to refer to their parents, and others may prefer to set up their parents to refer to their children. Only users who have the correct permissions will be able to access this option; otherwise, no dependent entities will be deleted.</p> <p>Currently, this module only supports entities that are in Core and the Rules:config entity. There is no explicit way to delete file entities in Core and, therefore, there is no delete confirm page and not supported in this module.</p> <h2>Project Page</h2> <p><a href="http://drupal.org/sandbox/atozstudio/1892808">http://drupal.org/sandbox/atozstudio/1892808</a></p> <h2>Git Repository</h2> <p>git clone <a href="http://git.drupal.org/sandbox/atozstudio/1892808.git">http://git.drupal.org/sandbox/atozstudio/1892808.git</a> entity_reference_cascade_delete</p> <h2>Requirements</h2> <p><a href="http://www.drupal.org/project/entityreference">Entity Reference</a></p> <h2>Installation</h2> <p>Install as usual. See <a href="http://www,drupal.org/documentation/install/modules-themes/modules-7">Installing contributed modules (Drupal 7)</a> for further information.</p> <h2>Configuration</h2> <p>1. Go to Entity Reference Cascade Delete settings (admin/config/content/ercd) to choose the correct entity reference model. Then choose which entities can trigger a cascade deletion when they are deleted and which entity types will be subject to the cascade deletion. Keep in mind that users will have the option of unselecting all specific entities on the "confirm delete" pages.<br> 2. Set appropriate permissions for each role. Permissions are broken down to each parent-child entity reference.</p> <h2>Troubleshooting</h2> <p>If you don't see any referencing/referenced entities showing up--or not as many as you expected to see--when deleting an entity, check the following things: </p> <ol> <li>Make sure you have actually enabled a cascade deletion for that entity.</li> <li>Make sure your user role has permission to perform the cascade deletion.</li> <li>Check if the entites you were expecting to see are referenced/referencing an entity that is outside the scope of the cascade.</li> </ol> <h2>Reviews of Other Projects</h2> <ul> <li><a href="http://drupal.org/node/1872926">http://drupal.org/node/1872926</a></li> <li><a href="http://drupal.org/node/1086416">http://drupal.org/node/1086416</a></li> <li><a href="http://drupal.org/node/1892752">http://drupal.org/node/1892752</a></li> <li><a href="http://drupal.org/node/1191490">http://drupal.org/node/1191490</a></li> </ul>
