Par Rick Anderson by Rick Anderson. Ce document fait partie de la mise en route avec ASP. In this section, you'll create a new MoviesController class and write code that retrieves the movie data and displays it in the browser using a view template.

Build the application before going on to the next step. If you don't build the application, you'll get an error adding a controller. For the Controller name enter MoviesController. The image below shows the completed dialog. If you get an error, you probably didn't build the application before starting adding the controller.

Visual Studio creates the following files and folders: Visual Studio automatically created the CRUD create, read, update, and delete action methods quatre etapes simples meilleure configuration pour le robot sur options binaires views for you the automatic creation of CRUD action methods and views is known as scaffolding.

You now have a fully functional web application that lets you create, list, edit, and delete movie entries. In other words, the browser request http: Quatre etapes simples meilleure configuration pour le robot sur options binaires result quatre etapes simples meilleure configuration pour le robot sur options binaires an empty list of movies, because you haven't added any yet.

Select the Create New link. Enter some details about a movie and then click the Create button. You may not be able to enter decimal points or commas in the Price field. To support jQuery validation for non-English locales that use a comma "," for a decimal point, and non US-English date formats, you must include globalize. I'll show how to do this in the next tutorial. Pour le moment, entrez simplement des nombres entiers tels que For now, just enter whole numbers like Clicking the Create button causes the form to be posted to the server, where the movie information is saved in the database.

Create a couple more movie entries. Try the EditDetailsand Delete links, which are all functional. A portion of the movie controller with the Index method is shown below. A request to the Movies controller returns all the entries in the Movies table and then passes the results to the Index view.

The following line from the MoviesController class instantiates a movie database context, as described previously. You can use quatre etapes simples meilleure configuration pour le robot sur options binaires movie database context to query, edit, and delete movies. Earlier in this tutorial, you saw how a controller can pass data or objects to a view template using the ViewBag object.

The ViewBag is a dynamic object that provides a convenient late-bound way to pass information to a view. MVC also provides the ability to pass strongly typed objects to a view template. This strongly typed approach enables better compile-time checking of your code and richer IntelliSense in the Visual Studio editor. The scaffolding mechanism in Visual Studio used this approach that is, passing a strongly typed model with the MoviesController class and view templates when it created the methods and views.

The Details method is shown below. The id parameter is generally passed as route data, for example http: You could also pass in the id with a query string as follows: If a Movie is found, an instance of the Movie model is passed to the Details view: By including a model statement at the top of the view template file, you can specify the type of object that the view expects.

When you created the movie controller, Visual Studio automatically included the following model statement at the top of the Details. This model directive allows you to access the movie that the controller passed to the view by using a Model object that's strongly typed. Par exemple, dans le Details. For example, in the Details. The Create and Edit methods and view templates also pass a movie model object.

Notice how the code creates a List object when it calls the View helper method in the Index action method. The code then passes this Movies list from the Index action method to the view: When you created the movie controller, Visual Studio automatically included the following model statement at the top of the Index.

This model directive allows you to access the list of movies that the controller passed to the view by using a Model object that's strongly typed. Par exemple, dans le Index. For example, in the Index. Among other benefits, this means that you get compile-time checking of the code and full IntelliSense quatre etapes simples meilleure configuration pour le robot sur options binaires in the code editor: Entity Framework Code First detected that the database connection string that was provided pointed to a Movies database that didn't exist yet, so Code First created the database automatically.

Si vous ne voyez pas le Movies. If you don't see the Movies. By default, EF will make a property named ID the primary key. Right-click the Movies table and select Show Table Data to see the data you created. Notice how the schema of the Movies table maps to the Movie class you created earlier.

Entity Framework Code First automatically created this schema for you based on your Movie class. If you don't close the connection, you might get an error the next time you run the project.

You now have a database and pages to display, edit, update and delete data. In the next tutorial, we'll examine the rest of the scaffolded code and add a SearchIndex method and a SearchIndex view that lets you search for movies in this database.
