Rub on Rails Question

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",

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

You are right, welcome method was empty. Thank you.

2pm at night is even more relaxing, but management do not allows me to
sleep at that time :slight_smile:

All the Best!
