Managing chatter on documents

In this recipe, you will learn how to manage chatter on your documents and add a communication thread to a record.

Getting ready

For this recipe, we will reuse the my_library module from Chapter 8, Advanced Server-Side Development Techniques. You can grab an initial copy of the module from the Chapter23/ 00_initial_module directory of the GitHub repository for this book. In this recipe, we will add chatter to the library.book.rent model.

How to do it...

Follow these steps to add chatter on the records of the library.book.rent model:

1. Add the mail module dependency in the __manifest__.py file:

   ...
   'depends': ['base', 'mail'],
   ...

2. Inherit mail.thread in the Python definition of the library.book.rent model:

   class LibraryBookRent(models.Model):
       _name = 'library.book.rent'
       _inherit = ['mail.thread']
   ...

3. Add chatter widgets on the form view...
