Rails: Match each has_many with a belongs_to posted on 25 Feb 2011 21:53

Matching each belongs_to to a has_many might be tedious. You can check it on the bash shell:

A=parent_class; B=child_class; grep -R :$B app/models/*.rb | grep has_many | grep $A; grep -R :$A app/models/*.rb | grep $B

Then you'll see clearly parent and child classes are matching:

./parent_class.rb:  has_many :child_classes,                                  :dependent=>:destroy
./child_class.rb:  belongs_to :parent_class
