title: Issue with "rake" and won't connect to database
body: <p>I have a rails app i've been working on for a while and it was always working and testing fine. Then for some reason today when I tried rake db:migrate I get the message below. I have started using git recently. Whether that has anything to do with it I don't know.</p>
  
  <p>Gem::LoadError: You have already activated rake 10.5.0, but your Gemfile requires rake 10.4.2. Prepending <code>bundle exec</code> to your command may solve this.</p>
  
  <p>If i type bundle exec rake db:migrate it seems to complete the migration the issue now is that in the new view when the user hits the submit button the create action isn't called. So the data isn't entered into the database.</p>
  
  <p>Any ideas would be great. Thanks.</p>
