Django Multivaluedictkeyerror Error, How to Deal with It

django MultiValueDictKeyError error, how do I deal with it

Use the MultiValueDict's get method. This is also present on standard dicts and is a way to fetch a value while providing a default if it does not exist.

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

Generally,

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

MultiValueDictKeyError in Django

Sure, you are not passing username as a GET parameter while getting the http://127.0.0.1:8000/StartPage/ page.

Try this and observe username printed: http://127.0.0.1:8000/StartPage?username=test.

Use get() and avoid MultiValueDictKeyError errors:

request.GET.get('username', '') 

See also:

• Django request.GET
• Django - taking values from POST request

django returns MultiValueDictKeyError at / 'q'

try this

query = request.GET['q']
query = request.GET.get('q', '')  # use get to access the q

The get() method returns the value of the item with the specified key.

How should I deal with a MultiValueDictKeyError?

Change your submit input to have name as submit, otherwise it will not get into post data.

<input type="submit" value="Place order" class="submit" name="submit" />

Also, the value will be 'Place order', not 'place_order'.
