Question

I have a notes model, which has a many-to-many relationship with the users model. In the index view in the notes controller I have this form:

<form id='note_form' method="post" action="/notes/temp_path" >
    <input type="hidden" name="authenticity_token" value="<%= form_authenticity_token %>" />        
    <input type="text" size="30" name="start_date" id="start_date">
</form>

which points to the temp_path action in the notes controller. For some reason when this form is submitted, instead of running the code in the temp_path action, Rails is trying to load a certain note, and because it can’t, it redirects back to index.

Started POST "/notes/temp_path" for 127.0.0.1 at 2010-12-08 22:08:25 +1000

  UserNote Load (0.2ms)  SELECT "user_notes".* FROM "user_notes" WHERE ("user_notes"."note_id" = 0)
Redirected to http://localhost:3000/notes

I’m pretty sure the WHERE ("user_notes"."note_id" = 0) bit is causing the problem. But I’m not sure why this is even being done? Based on the line above it, User Load (0.3ms) SELECT "users".* ... it seems like it’s behind the scenes Rails stuff. Nowhere in the temp_path action do I need to load an existing note. How can I stop this? I’m using Rails 3.0.1. Thanks for reading.

You should show us the code of your controller. Have you any ‘redirect_to’ statements there? With any conditions?

Maybe you have some filters in your controller, maybe in ApplicationController? From the deprecation warning I see that you may have some code there.
