这是我最喜欢的设计师模特
favorite_designer.rb
class FavoriteDesigner < ActiveRecord::Base
belongs_to :user, :counter_cache => true
belongs_to :designer, :class_name => "User", :foreign_key => :designer_id
validates_presence_of :user_id
validates_presence_of :designer_id
validates_numericality_of :user_id, :unless => Proc.new{|f| f.user_id.blank?}
validates_numericality_of :designer_id, :unless => Proc.new{|f| f.designer_id.blank?}
end
如何使用shoulda在rspec中测试:counter_cache => true and :foreign_key => :designer_id
?
答案 0 :(得分:1)
您可以使用counter_cache
和with_foreign_key
匹配:
it { should belong_to(:organization).counter_cache(true) }
it { should have_many(:worries).with_foreign_key('worrier_id') }
