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):

You should have prepared that array (@composers) in controllers "welcome" method:
app/controllers/main_controller.rb
class MainController < ApplicationController
def welcome
@composers = Composer.find(:all)
end
end
