覆盖belongs_to has_many外键值

Question

I have something set-up with two models. user and posts . user has_many posts and posts belongs_to user. I created a bunch of posts using one admin user and now I want to assign each post to a different user . I tried creating a form for post and just updating the user_id field, but I get the message Unpermitted parameter: user_id and the field will not update - it just reverts back to the original user_id .

How can I force the form to accept the new user_id ?

Answer 1

Just had to add :user_id to params in the controller. Foolish oversight.
