Instance Method Details

#association(name, overrides = {}) ⇒ Object

Generates an association using the current build strategy.

Arguments:

name: (Symbol)
  The name of the factory that should be used to generate this
  association.
attributes: (Hash)
  A hash of attributes that should be overridden for this association.

Returns:

The generated association for the current build strategy. Note that
associations are not generated for the attributes_for strategy. Returns
nil in this case.

Example:

factory :user do
  # ...
end

factory :post do
  # ...
  author { |post| post.association(:user, :name => 'Joe') }
end

# Builds (but doesn't save) a Post and a User
FactoryGirl.build(:post)

# Builds and saves a User, builds a Post, assigns the User to the
# author association, and saves the Post.
FactoryGirl.create(:post)
