The MultiValueDictKeyError arises when you try to access the non-existent key in the MultiValueDict object.

For example: when accessing a non-existing key in the request.POST.

The MultiValueDict in django is a subclass of dictionay data structure that is customized to handle multiple values for the same key.

There are two quick solutions to this error.

Check if Key Exists Before Accessing

Use the in operator to check whether the dictionary object has the particular key or not.

if 'key' in request.POST:
    vaule = request.POST['key']

Use the get() Method with a Default Value

Use the dict.get('key', 'default') method by providing the default value. This default value will be returned if the specificed key does not exist in the MultiValueDict object.

value = request.POST.get('key', None)
