I am getting the following error when I point the browser to  
[http://localhost:3000](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):

Click on a composer’s name  
3: to see all of that composer’s works.

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 🙂
