Pages not rendering properly on Heroku - ruby-on-rails

Question

Hi I am in the midst of Ruby on Rails tutorial. MY pages are rendering perfectly on the localserver but NOT on Heroku. I have run the command "heroku run rake db:migrate". I also have gone through the Heroku logs. I am just not sure how to read them.
I am wondering if it has to do with my stylesheets but I replicated whatever was on my local server to github and heroku so not sure why it can't read it.
I am add a part of the logfile. I wish I could show snapshots but unfortunately I don't have rights to do so.
I would appreciate any help and tips on debugging this problem.

Answer 1

I hope you don't mind but I took the liberty of going to your site myself to see what the problem is. The issue is that you're configuring to use the asset pipeline but none of your assets are compiled. You can verify this is the case by visiting your main CSS file -- you'll notice there's nothing at all there.
This is likely because you forgot to include compilation directives at the top of your application.css. See the asset pipeline guide for full details, but I bet you're missing a line like this at the top of your application.css:
*= require_self
*= require_tree .

Answer 2

I had this problem before too, and I think it had something to do with precompiling your css file. Try going into config/environments/production.rb and add this config.assets.precompile += [ "blueprint/*.css" ]. I am assuming you're using the blueprint css file.
