Mvc controller with read/write actions and views using entity framework

NET MVC 4 controller methods, or have completed the "Helpers, Forms and Validation" Hands-On lab, you should be aware that many of the logic to create, update, list and remove any data entity it is repeated among the application.

Descriptions[ edit ] As with other software patterns, MVC expresses the "core of the solution" to a problem while allowing it to be adapted for each system. It is the application's dynamic data structure, independent of the user interface.

A view can be any output representation of information, such as a chart or a diagram. Multiple views of the same information are possible, such as a bar chart for management and a tabular view for accountants. The third part or section, the controller, accepts input and converts it to commands for the model or view.

It receives user input from the controller. The view means presentation of the model in a particular format. The controller responds to the user input and performs interactions on the data model objects.

The controller receives the input, optionally validates it and then passes the input to the model.

History[ edit ] One of the seminal insights in the early development of graphical user interfaces, MVC became one of the first approaches to describe and implement software constructs in terms of their responsibilities. The introduction of the frameworks Django Julyfor Python and Rails Decemberfor Rubyboth of which had a strong emphasis on rapid deployment, increased MVC's popularity outside the traditional enterprise environment in which it has long been popular.

Several web frameworks have been created that enforce the pattern. These software frameworks vary in their interpretations, mainly in the way that the MVC responsibilities are divided between the client and server. In this approach, the client sends either hyperlink requests or form submissions to the controller and then receives a complete and updated web page or other document from the view; the model exists entirely on the server.

February Simultaneous development[ edit ] Because MVC decouples the various components of an application, developers are able to work in parallel on different components without impacting or blocking one another. For example, a team might divide their developers between the front-end and the back-end.

The back-end developers can design the structure of the data and how the user interacts with it without requiring the user interface to be completed.

Conversely, the front-end developers are able to design and test the layout of the application prior to the data structure being available.

Code reuse[ edit ] By creating components that are independent of each other, developers are able to reuse components quickly and easily in other applications. The same or similar view for one application can be refactored for another application with different data because the view is simply handling how the data is being displayed to the user.

Advantages[ edit ] Simultaneous development — Multiple developers can work simultaneously on the model, controller and views. High cohesion — MVC enables logical grouping of related actions on a controller together.

The views for a specific model are also grouped together. Low coupling — The very nature of the MVC framework is such that there is low coupling among models, views or controllers Ease of modification — Because of the separation of responsibilities, future development or modification is easier Multiple views for a model — Models can have multiple views Disadvantages[ edit ] Code navigability — The framework navigation can be complex because it introduces new layers of abstraction and requires users to adapt to the decomposition criteria of MVC.

Multi-artifact consistency — Decomposing a feature into three artifacts causes scattering. Thus, requiring developers to maintain the consistency of multiple representations at once.

In compiling the following list I picked out those descriptions which are not actually unique to OOP as those features which already exist in non-OO languages cannot be used to differentiate between the two.

I am working on an barnweddingvt.com MVC5 e-commerce site and my focus is on how to apply database migrations to such a site (see previous articles on this subject). I have decided that for complex database changes I will take the web site “Down for maintenance” while I make the changes.

One final thing: a controller can contain many actions, each of which corresponds to a different page (ignoring AJAX at this point). Each page is accessible via a unique URL that is composed from the controller name and the action name: //controller>/.
