每次我尝试在视图中使用Datetime_select时,应用程序都会抛出属性错误.
Mongoid::Errors::UnknownAttribute:
Problem:
Attempted to set a value for 'fromtime(1i)' which is not allowed on the model Event.
Summary:
Without including Mongoid::Attributes::Dynamic in your model and the attribute does not already exist in the attributes hash, attempting to call Event#fromtime(1i)= for it is not allowed. This is also triggered by passing the attribute to any method that accepts an attributes hash, and is raised instead of getting a NoMethodError.
Resolution:
You can include Mongoid::Attributes::Dynamic if you expect to be writing …我似乎在使用FactoryGirl创建Time对象时遇到了一些麻烦.当我这样做:
factory :invite do |n|
fromtime Time.now + 1.weeks
totime Time.now + 1.weeks + 1.hour
end
工厂工作正常,但我希望有许多顺序的邀请.所以当我这样做时:
factory :invite do |n|
fromtime Time.now + n.weeks
totime Time.now + n.weeks + 1.hour
end
我收到这个错误
