Hello guys,
I''ve been developing in Ruby for a few months and I am starting to
work with Rails. I am having a problem right from the start and I
think I am not doing anything wrong. I have performed the following
steps:
1. run rails test
2. run script/server and it works perfectly connecting to the database
without problems (sqllite)
5. run script/generate scaffold release_notes title:string
version:string content:text
6. rake db:migrate
7. shutdown the server and start it again
8. http://localhost:3000/release_notes/new and it works just fine
9. After I click on create I get the error below. I have checked that
removing all the "link_to" entries the error disappear. any ideas?
what am I forgetting?
NoMethodError in Release_notes#index
Showing release_notes/index.html.erb where line #15 raised:
You have a nil object when you didn''t expect it!
The error occurred while evaluating nil.to_sym
