Factory.define :valid_thing, :class => Thing do |t|
t.name 'Some valid thing'
t.user { Factory(:valid_user) }
end
Wrapping the call in {} causes Factory Girl to not evaluate the code inside of the
braces until the :valid_thing factory is created. This will force it to wait until the
:valid_user factory has been loaded (Your example is failing because it is not yet
loaded), it will also cause a new :valid_user to be created for each :valid_thing
rather than having the same user for all :valid_thing's (Which is probably what you
want).
