Routing error with font-awesome assets in Rails 3 - ruby-on-rails

The font-awesome css file is located in app/assets/stylesheets/font-awesome.css and yet the error is:

Based on another Github answer (https://github.com/seyhunak/twitter-bootstrap-rails/issues/535), fontawesome-webfont.woff is located in vendor/assets/font but the error is:

I have tried pre-compiling the assets before running the app but that doesn't work either. Any ideas would be much appreciated!


This is the general guide to using font-awesome with Rails.
However I usually just use this gem which does it for you.

Active admin without devise configuration on rails mountable engine

I am currently trying to install active admin on a rails mountable engine. The host application for the engine has authentication configured using devise. I have installed active admin without devise authentication using the --skip-user option [while running rake active_admin:install]. I am mounting the engine on the host application on the path /admin_app/.
When trying to access the URL:
http://localhost:3000/admin_app/admin
I am getting the following error

Here are my routes
resources :users
root 'users#new'
Why would the app try to post index.html?And why would my tests pass but when I run the server it would not work?I had devise installed but then decided not to use it so I did a git reset --hard and continued that way.could that be the issue?How can I fix this?

This is pretty scary, but I've spent about a week developing an app and have just been hit with the following error when running the 'Rails S' command. My app doesn't seem to want to start up anymore.
I'm sure with the help of the wonderful Stackoverflow community we can solve this one!
Edit: Thought I would include my GitHub for good measure - https://github.com/Apane/Startupblog
