我在我的specs
中使用了shoulda_matchers
。对于此测试未定义的方法`columns_hash'
it { should validate_uniqueness_of(:name).scoped_to(:role_id) }
我得到这个错误:
Expected errors to include "has already been taken" when name is set to "arbitrary_string", got errors: ["name is already taken (\"arbitrary_string\")"]
当我改变了测试:
it { should validate_uniqueness_of(:name).scoped_to(:role_id).with_message('is already taken') }
我收到此错误:
NoMethodError:
undefined method `columns_hash' for Activity:Class
我型号只有一个字段 - name
如果你有一个使用ActiveRecord和Mongoid的rails项目,该怎么办? – aag
