Rails 3 Routing Error in One Branch but not in the Other - ruby-on-rails-3

Question

I'm using: Rails 3.1.3, HAML and Passenger
I'm having a route problem in my staging branch, but in the other branch that was merged into staging I have no problem at all. I've tried comparing my routes files and the form files from these two branches using git diff but the two files are the same in the branches.
A weird thing is the rendered error page. Here's a link to an screenshot
Error message
And also the error from passenger:
Rendered time_entries/_form_fields.haml (173.2ms)
Rendered time_entries/_form.haml (194.7ms)
Rendered time_entries/edit.haml within layouts/application (196.6ms)
Completed 500 Internal Server Error in 448ms
ActionView::Template::Error (No route matches {:controller=>"time_entries"}):
5: .field
6: = form.submit "Save"
7: |
8: = link_to "Cancel", project_time_entries_path(#project)
app/views/time_entries/_form.haml:8:in `block in _app_views_time_entries__form_haml__894171410_105032920'
app/views/time_entries/_form.haml:3:in `_app_views_time_entries__form_haml__894171410_105032920'
app/views/time_entries/edit.haml:2:in `_app_views_time_entries_edit_haml__805073897_105087770'
I attach you the code from my route and my form
form.haml
.app-form
= error_messages_for :time_entry
= form_for [#project, #time_entry] do |form|
= render :partial => 'form_fields', :locals => {:form => form}
.field
= form.submit "Save"

= link_to "Cancel", project_time_entries_path(#project)

Thank's in advance.

Answer 1

On app/views/time_entries/_form.haml:8, does #project exist? Perhaps your staging branch uses a different database and hence the #project you think is there is not?
Also, run rake routes and verify the project_time_entries is in the output. Perhaps you need a :as on one of your routes.
