Question

Getting this error in posts>show when I try to load up a form.

The form is for users to send messages to each other. Grateful for any feedback!

Thanks.

Answer 1

The error is saying there is no method user on the Post model. It points you directly to the first line.

<%= form_remote_tag (:update => 'message', :url => {:controller => 'main', :action => 'send_message', :user_id => @post.user.id}) do %>

so I’d say

@post.user.id is your problem statement, that model doesn’t have a method user but it’s hard to know for sure without seeing the Post model.
