oh yeah thx!

If anyone want to create a user via API and link the user to an Company you can use the following code:

user_id=models.execute_kw(db, uid, password, 'res.users', 'create', [{'name':"Username",    'login':'Username@gmail.com','company_ids':[(4, comp_id,False)], 'company_id':comp_id, 'new_password':'123456'}])

Hi Fabian,

W.r.t your query, I have go through your query and tried to replicate it. Following might be the reasons due to which you had been receiving the issue :-

1) While creating the user, the option of Multi Companies under tab Usability needs to be selected for that particular user.

2) Post this the required companies must be added under “Allowed Companies” for that particular user.

By doing so your issue of linking a User to an new Company would be solved.

Hope this helps

Cheers!!
