AttributeError: 'Request' object has no attribute 'is_xhr'

This error occurs when a Request object in the code does not have the attribute is_xhr. The is_xhr attribute is commonly used to check if the request is an AJAX request (i.e., made through XMLHttpRequest).

To resolve this issue, you can follow these steps:

1. First, make sure that the Request object in your code is actually supposed to have an is_xhr attribute. Double-check the documentation or the source code of the Request object to confirm if is_xhr should exist.

2. If the Request object is expected to have an is_xhr attribute, then you may need to update your code to fix the error. One possible solution is to check the existence of the attribute before accessing it to avoid the AttributeError. You can use the hasattr function to check if the attribute exists.

   if hasattr(request, 'is_xhr'):
       # Access the is_xhr attribute
       is_ajax_request = request.is_xhr
   else:
       # Handle the case when is_xhr attribute is not available
       is_ajax_request = False
   

3. If the Request object does not have the is_xhr attribute by default and you need it for your application, you might need to extend or modify the Request object to include the is_xhr attribute. This can be done by subclassing the Request object and adding the attribute with appropriate logic.

Remember to thoroughly test your code after applying any changes to ensure that it functions as expected without any attribute errors.
