在 django 中验证 POST 请求的正文

Question

I have a view in django that sign's up a client and I have a model for the client and a form that looks like this:

from django.forms import ModelForm
from api.models.client import Client


class SignUpForm(ModelForm):
    class Meta:
        model = Client
        fields = ['first_name', 'last_name']

In my view I would like to validate the data in the request but my problem is that the paramters in the request are camelCase and not snake_case so when I try to validate the data it doesn't work.

def sign_up(request):
    body = json.loads(request.body)
    form = SignUpForm(body)
    print(form.is_valid())
    return HttpResponse('this is a test response')

Is there a clean way of making this work? Also is this the correct way to do what I'm trying to do?

Answer 1

You can iterate through the body keys, use regex to rename the key and adding to a new dictionary.

def camel_to_snake(val):
    return re.sub('([A-Z]+)', r'_\1', val).lower()

body = json.loads(request.body)
new_body = {camel_to_snake(k): v for k, v in body.items()}
