Extend templates from vendor bundles

For extend or replace templates (or another types of resource files) you just have to create a folder in app/Resources with the name of the bundle, from which you want to extend the template, and put the new file inside a folder called ‘view’ following the same structure that it has in the vendor. For example for login.html.twig located in vendor/Sonata-project/user-bundle/resources/views/security/login.html.twig, you have to put it in app/Resources/SonataUserBundle/security/login.html.twig

"Help, I keep getting a 'Permission Denied (publickey)' error when I push!"

This means, on your local machine, you haven't made any SSH keys. Not to worry. Here's how to fix:

1. Open git bash (Use the Windows search. To find it, type "git bash") or the Mac Terminal. Pro Tip: You can use any *nix based command prompt (but not the default Windows Command Prompt!)
2. Type cd ~/.ssh. This will take you to the root directory for Git (Likely C:\Users\[YOUR-USER-NAME]\.ssh\ on Windows)
3. Within the .ssh folder, there should be these two files: id_rsa and id_rsa.pub. These are the files that tell your computer how to communicate with GitHub, BitBucket, or any other Git based service. Type ls to see a directory listing. If those two files don't show up, proceed to the next step. NOTE: Your SSH keys must be named id_rsa and id_rsa.pub in order for Git, GitHub, and BitBucket to recognize them by default.
4. To create the SSH keys, type ssh-keygen -t rsa -C "your_email@example.com". Th

Let Sonata admin users only edit entities they own

First configure ACL permissions correctly:

https://sonata-project.org/bundles/admin/master/doc/reference/security.html

Remember these 3 things explained in the link:

1. Install the ACL tables: php app/console init:acl
2. If you have Admin classes, you can install or update the related CRUD ACL rules (I HAD PROBLEMS NOT EXECUTING THIS ONE, REMEMBER TO RUN IT):
