FactoryGirl screws up rake db:migrate process

Question

I am doing TDD/BDD in Ruby on Rails 3 with Rspec (2.11.0) and FactoryGirl (4.0.0). I have a factory for a Category model:

FactoryGirl.define \"Category\" do         


        

Answer 1

A simple fix to this issue is to delay evaluation of any models in your factories by wrapping them in blocks. So, instead of this:

factory :cake do
  name "Delicious Cake"
  frosting Frosting.new(:flavor => 'chocolate')
  filling Filling.new(:flavor => 'red velvet')
end

Do this (notice the curly braces):

factory :cake do
  name "Delicious Cake in a box"
  frosting { Frosting.new(:flavor => 'chocolate') }
  filling { Filling.new(:flavor => 'red velvet') }
end

If you have a lot of factories this may not be feasible, but it is rather straightforward. See also here.
