How to Handle MultiValueDictKeyError in Django Forms?

Handling MultiValueDictKeyError in Django

When attempting to save an object with a form in Django, you may encounter a MultiValueDictKeyError if a checkbox field is not selected. This error occurs because the POST data for the checkbox is not available in the request.

To resolve this, you should use the MultiValueDict's get method instead of direct indexing. The get method takes a key and a default value, returning the value associated with the key or the default value if the key is not present.

is_private = request.POST.get('is_private', False)

In general, the syntax for get is:

my_var = dict.get(<key>, <default>)

This allows you to handle missing values gracefully, ensuring that your code does not fail due to a MultiValueDictKeyError.
