Downloaded the gem and followed the instructions. Unfortunately I am getting the above error message. I noticed that when I run:
rails generate formtastic:install
only those 2 files were created:
It looks like my_fomtastic_changes file was not created in this go. I tried creating the file manually in the initializes directory although i don't know if that is the proper thing to do. This did not solve the problem. I am using Ruby 1.9.3 and Rails 3.2.8. I would appreciate if you could have a look into this.
I created the file manually in stylesheets as my_formtastic_changes.css and now the error message is appearing no loger, however my form does not show in the view. Any idea why that can be?
Sorry for the late reply,
In fact, "my_formtastic_changes.css" is the file in which you should write your modifications to the formtastic css. So, yes you used the right way.
