I have a model with name Module

class Module \< ActiveRecord::Base  
set\_table\_name “modules”  
belongs\_to :tabs  
…

end

Some how I am getting error : “undefined method `table\_name’ for  
Module:Class”

I assume this is happening because there is some class in rails with  
same name, I would appreciate if some body can show me way to solve  
this problem.

Not just in Rails, in Ruby! Module (capitalized) is a reserved word,  
like Class. You’ll have to pick a different model name.
