symfony1 - database structure for threads that are editable by many users? -

At the moment I have a column "user_id" in the "thread" table, so a thread belongs to a user.

I want to make it like a stack waveflow that a thread can be editable by many users and you can see when they have edited, what they edit, roll back the changes And so on.

im symfony, is there a plugin for this?

If not, is there a third part to download the library / plugins to integrate the existing database?

I do not know how to apply it looks like mediawiki, which already exists?

thanks

Using the User Id to Remember the Original Manufacturer of the Thread As a way, then let any user edit a thread, not just limit them to the manufacturer.

To rollback, you will need to store your thread versions. There must be a thread table and a version table in a way.

Thread table will point to the current version, but if you need to rollback, then you can retrieve it from the version table, which is the history of previous versions.
