How can I make a validation for post fetch input? I manually validate if the first digit has empty space or isalnum to make update operation as below but I wonder is there a better approach?
def update_user_meta(request):
if request.method == "POST":
name = request.POST.get("name")
if name is not None and name[0:1].isalnum() == True:
selectedUser.name = name
else:
selectedUser.name = selectedUser.name
You should use django forms https://docs.djangoproject.com/en/3.2/topics/forms/ .
Unless this view is an API then use the serializers from the django rest framework.https://www.django-rest-framework.org/api-guide/serializers/
There are built-in functions to make field validations. It can be done with Regex Validator.
List of them are in the documents. https://docs.djangoproject.com/en/3.2/ref/validators/
