ruby - Single-table inheritance using a datetime column -


I have a user class that handles both registered and unregistered users in our database. I have maintained the user and registered users of subclasses I'm leaning towards using STI, but I think it's adding some repetition to my code where it's not really necessary.

I am currently planning for the ad "Type" and "Registered" column. In fact everyone needs to be present whether or not they are presently included on the "registered_at" users. 

  User t.string "type" t.datetime "register_at"

This rail does not fit the STI conference, but it seems like something Reduce the repetition which is otherwise unnecessary. Does this make sense and how do I create it in my user model?

Why not only use scope? Scope: unregistered, lambda {where (: registered_it => zero)} scope: registered, lambda {where ("registered_t is not empty")}

and like them: 

  User.registered.first

Edit

Get your Subclasses from User and you can use default_scope , eg: 

  class unregisteredUser & lt; User default_scope {uncontrolled} # callback, etc. End

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
