I am getting the following error when I point the browser to
http://localhost:3000
I have checked the composers table and it has two records. Can someone please
help me to fix this
problem? TIA
NoMethodError in Main#welcome
Showing app/views/main/welcome.rhtml where line #5 raised:
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.each
Extracted source (around line #5):
2: <p>Click on a composer''s name
3: to see all of that composer''s works.</p>
4: <ul>
5: <% @composers.each do |composer| %>
6: <li><%= link_to "#{composer.first_name}
#{composer.last_name}",
7: :controller => "composer",
8: :action => "show",
