Creating a View (SAP Library - Model View Controller Tutorial)

Creating a View

Use

If you do not always want to use the write function to create the HTML page content (as described in Creating a Controller), and you want to create it as pure HTMLO layout instead, then create a view that you can call from the controller.

Procedure

Begin as if you are creating a normal page with flow logic in your BSP application.

To do this, choose Create ® Page.

In the following dialog box, enter a name and short description of the view and select View as the page type:

Choose

Create the attributes for the variable parts of the view.

Note

You cannot define auto-page attributes, since views cannot be called directly from the browser.

Create the following attribute:

Define the layout as usual:

<%@ page language="abap" %>

<html>

<head>

<title> Layout for Controller </title>

</head>

</head>

<H1>View Example</H1>

<H3>Hello, user <%= name%></H3>

</body>

</html>

Activate the view.

Finally, adjust the DO_REQUEST method to the controller class.

Here, the schema is always the same. First you create the view, then you set the attributes, and then you call the view. (For the time being you can ignore the warning concerning exception CX_STATIC_CHECK, or you can set a try-catch block around the calls):

method DO_REQUEST .

data: myview type ref to if_bsp_page.

myview = create_view( view_name = 'view_test.htm' ).

myview->set_attribute( name = 'name' value = sy-uname ).

call_view( main_view ).

endmethod.

Activate your class and test your controller.

Result

You have created your own view for the layout.
