Are calculated quantities a part of the Model, View or Controller?
java,model-view-controller,design
Go with your feeling and establish that attribute as a synthetic field in your model. So no extra physical field, but put the derivation function down as a getter. In my opinion that's OK, because that getter does only little more than a really dumb field accessor, and the definition...

Some doubts related this Swing MVC implementation. Opening a database connection should be a Controller task?
java,swing,design-patterns,model-view-controller,architecture
So, MVC doesn't actually explicitly address persistence. There are really two schools of thought here. Bake it into the model, so that the model becomes "self persisting". Or do it in the controller. Opening it in the view layer is absolutely not accepted practice. There is a definite mixing of...

angularjs,spring,model-view-controller,data,hateoas
To be truly HATEOAS compliant, the service (spring) needs to provide to the client all the hypermedia controls (links) to perform sorting. The client should never sort by some data field...it should only sort by what sort options are provided to the client by the server. This sorting may itself...
Dependency Injection asp.net 5 custom classes, what is correct way?
c#,asp.net,model-view-controller,asp.net-5
[FromServices] is just an MVC concept. It is not available to other parts of the ASP.NET 5 stack. If you want to pass dependencies down the chain you have a few options: Pass the service provider. This is quite an anti-pattern because your objects need to depend on the DI...

Play Scala activator compile command shows value userid is not a member of play.api.data.Form[models.Changepas sword]
scala,model-view-controller,playframework,playframework-2.0,typesafe-activator
You can't use the value of the form as a parameter for the route: @form(routes.Users.updatePassword(userForm.userid.get)) The userid depends on the form and could therefore change. In any case, you would access the userid of the form using userForm("userid") and not userForm.userid (although it might not be what you want/need). A...

ios,swift,api,model-view-controller,alamofire
Your loadAdInfo method is asynchronous.

in ActiveRecord::Relation, is it preferable to scope by parent in the model or set @parent in the controller
ruby-on-rails-4,activerecord,model-view-controller,scope,parent-child
Not sure whether it's possible, but it will couple most of your app to the default_scope implementation, which IMHO is a very bad idea. You might end up needing to change this implementation down the line, which is going to have pretty high impact. It will also make your unit...
MVC of a button to implement different types of button.Looping of the button element doesnot display all the elements in div
javascript,html,model-view-controller,event-handling,javascriptmvc
The problem is that you are not creating 10 button elements as you expect, you are creating only one.

Then you create an object which uses...
