Routes work in Development But not in Production - ruby-on-rails

Question

Weird Error. I have some routes that work perfectly during development but once i deploy and try to access them it comes up with page does not Exist error
I have the following routes.rb file:
TransportUnl::Application.routes.draw do
resources :trucks
resources :shipments do
collection do
get :autocomplete_location_cs
end
end
devise_for :users do
get '/users/sign_in' => 'devise/sessions#new'
get '/users/sign_out' => 'devise/sessions#destroy'
end
root :to => 'info#index'
resources :info do
collection do
get 'about'
get 'contact'
get 'you_dont_have_a_full_account'
get 'help'
end
member do
get 'index'
end
end
resources :companies
end
Not everything is setup yet. but i am getting a page not found error when i go to:
www.website.com/shipments
www.website.com/trucks
as well as others in production. The main index page works and you can login but these pages come up not found.

the Link is created like this:
<%= link_to "My Account", edit_company_path(current_user.company_id) %>

Answer 1

As you can see from logs, you got error page because of line 78 of app/views/shared/_header.html.erb file.
In this piece of code, where you creating link
<%= link_to "My Account", edit_company_path(current_user.company_id) %>
Check if company_id is not nil for that particular user. I'm pretty sure it's nil in your case.
As you can see from error logs, it tries to get action edit as collection action of companies controller - companies/edit. You don't have this route defined. But if current user will have company_id, the link will be built correctly and you wont receive an error.
