This example demonstrates how to send authenticated requests to the OData service. The main idea is to handle the ODataContext.beforeSend event and add login information to the header of your request.

This example seems to be incomplete as it doesn't have the OData Service project included in it to demonstrate the functionality.
I would appreciate if you can create the ODataService project and demonstrate the example fully.

12/29/2015 12:41:55 AM It's ok. I prefixed the "app" with the name of my application. Now the error is not displayed. (Guess I get it)
but i'd like to know where should I put the db.js? Is it in the same folder as "login" and "index" ?
Because I got this error :
"Error: 'TypeError: TestApp.db is undefined', line 4, file 'http://localhost:54294/views/index.js'."

You can place the db.js file into any folder. The main requirement is that a reference to this file should be placed before a reference to index.js.

12/29/2015 1:33:42 PM I did not understand what does "db.js" really do?
Here are the sequence of ideas in my head:
1- User enter his (UserName & password) then click LoginButton
2- the index page is shown and it is expected to display a list of categories. The data source of this page is the "CategoryList"
Now I don't understand what is exactly the "categoryList". Is it a table in the DB which is linked to My OdataService?
what do this two lines mean :
key: "CategoryID",
name: "Categories"
So briedfly I need more explanation to make the db.js clear in my head?
thks to help.
