pulling data form another controller's table

I'm kind of new to RoR so this may be a stupid question, but is there any way to pull data associated with one controller into the view of another? For example if I have 2 controllers, AController and BController and I have a table in my database for AController with the value Text, can I pull the data from AController.Text into a BController view? Let me know if you need any more information, Thanks.

Tables don't belong to controllers. Any controller in your app can use any of the models it needs to.
