'You may need to add a dependency on the parent class\' module.' % (name, parent_name))
TypeError: The model "openacademy.course" specifies an unexisting parent class "mail.thread" You may need to add a dependency on the parent class' module.

Help me to get rid of this.. :-(

Answer 1

just simply add this tag to your form view after all the fields, <div class=”oe_chatter”> ... content of the bottom part ... </div> and I hope this will help you. for more details https://doc.openerp.com/trunk/server/form-view-guidelines/

try this in your xml,

   <div class="oe_chatter">
       <field name="message_follower_ids" widget="mail_followers" groups="base.group_user"/>
       <field name="message_ids" widget="mail_thread"/>
   </div>
