When you are working with o2m & m2m fields, you should use the special operators (search by the key '(0, _, values)' here: https://www.odoo.com/documentation/8.0/reference/orm.html)

In your example:

for follower in project_id.message_follower_ids:

 if follower not in task_id.message_follower_ids:

  task_id.message_follower_ids = [(4,partner.id)]


Or in case task for sure doesn't have the same followers before:

task_id.message_follower_ids = [(6,0,project_id.message_follower_ids.ids)]


You may add this to create or write

i'm using this method as button, but i get error NameError: global name 'project_id' is not defined

here is my method

@api.multi

def add_project_followers(self):

for follower in project_id.message_follower_ids:

if follower not in task_id.message_follower_ids:

task_id.message_follower_ids = [(6, 0, project_id.message_follower_ids.ids)]

It was an example! Please read the documentation how to write functions in Odoo / Python. In your case you try to apply a variable which doesn't exist. It should be sth like:

@api.multi

def add_project_followers(self):

for task in self:

for follower in task.project_id.message_follower_ids:

if follower not in task.message_follower_ids:

task.message_follower_ids = [(4, follower.id)]
