Jquery ajax csrf framework for Django

1. Framework to extend the jquery ajax() function to construct post requests that contain a csrf token. 2. The example view used with the framework takes JSON data and returns JSON data containing either: 3. "success" with a message and additional dictionary of JSON data to use in the page 4. "error" with an error message. 5. The ajax function framework satisfies Django's csrf requirements by injecting a csrf token into the post requests created using the function. This example is a form with ~160 fields that we wanted to help fill in customer information to automatically. 1. User calls the lookup() script from the onblur attribute of the customer_id form field by leaving the field. 2. The lookup script takes the contents of the customer_id formfield and uses the jquery ajax() function to construct a JSON post request to the "/json /?act=" url. 3. The json view takes actions as get requests. We pass the post request to the JSON url already including the get request. "/json/?act=lookup" 4. The jquery framework in the snippet includes a csrf token in the ajax request automatically. 5. The customer_id is passed as JSON to the json view lookup action and customer details are attempted to be looked up in the database. 6. If successful the request returns a JSON dictionary of customer details which are pushed into the formfields using javascript in the lookup() function. The end result is if the user fills out the customer_id field of the form first (which we suggest with tooltip overlay) the customer name and address information will populate automatically. *Credit to Guangcong Luo https://github.com/Zarel
