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
