Devise Admin works locally but not on Heroku - ruby-on-rails

Question

I'm creating an app using Ruby On Rails and Devise. I've created a User model and an Admin model and I have the app working fine when I run it locally but when I run it on heroku I'm having problems. The trouble is when I try to create a new admin I'm shown an error message that says "We're sorry, but something went wrong." I've already done a rake db:migrate and heroku run rake db:migrate. When I check heroku logs I see this:

For some reason unknown to me heroku is not linking to admins/registrations/new.html.erb but instead it's linking to devise/registrations/new.html.erb where it's reading the 'name' attribute that is showing up as an undefined method error.
My controllers/admins/registrations_controller.rb file looks like this:
class Admins::RegistrationsController < Devise::RegistrationsController
end
My routes.rb file looks like this:
MyFirstApp::Application.routes.draw do
get "users/show"
devise_for :admins, :controllers => { :registrations => "admins/registrations", :sessions => "admins/sessions" } do
get "/admins/sign_up" => "admins/registrations#new"
get "/admins/sign_in" => "admins/sessions#new"
end
resources :posts
devise_for :users
match 'users/:id' => 'users#show'
root :to => 'pages#home'
get 'about' => 'pages#about'
end
My development.rb file
MyFirstApp::Application.configure do

# If you find yourself ignoring temporary files generated by your text editor

/db/*.sqlite3
# Ignore all logfiles and tempfiles.
/log/*.log

# Ignore Paperclip unloaded files
/public/system
I'd appreciate any help I can get! This is my first time creating an app so I apologize if my question is dumb but I'm stuck and I need some help!

Answer 1

First check your gitrepo to make sure the file, or a related file, for some reason has been ignored.
And if that isn't the issue then just nuke the heroku project and start over.
Heroku has a special way of sometimes not creating new repos/projects correctly. The fail rate is pretty small, but you might have just rolled snake eyes.
If that doesn't work then post your production.rb and development.rb.
