我在我的Rails应用程序中设置了一个ActiveModel类,如下所示：
- class MyThingy
- extend ActiveModel::Naming
- extend ActiveModel::Translation
- include ActiveModel::Validations
- include ActiveModel::Conversion
- attr_accessor :username,:favorite_color,:stuff
- def initialize(params)
- #Set up stuff
- end
- end
我真的希望能够做到这一点：
- thingy = MyThingy.new(params)
- thingy.update_attributes(:favorite_color => :red,:stuff => 'other stuff')
我可以自己编写update_attributes,但我觉得它存在于某个地方.可以？
解决方法
不,但这种情况有共同的模式：
- class Customer
- include ActiveModel::MassAssignmentSecurity
- attr_accessor :name,:credit_rating
- attr_accessible :name
- attr_accessible :name,:credit_rating,:as => :admin
- def assign_attributes(values,options = {})
- sanitize_for_mass_assignment(values,options[:as]).each do |k,v|
- send("#{k}=",v)
- end
- end
- end
