Comment (by Roman Paranichev):
Steps to reproduce:
1. create html form
{{{
<form action="/payment/">
<input type="number" step="0.01" name="amount" value="0.01" required>
<input type="submit" value="Submit">
</form>
}}}
2. create django-form for validation:
{{{
from django import forms
class CreatePaymentForm(forms.Form):
amount = forms.DecimalField(min_value=0.01, max_digits=12,
decimal_places=2)
}}}
3. Try to validate from in a view class:
{{{
import json
from django.http import HttpResponse
from django.views.generic import View
from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator
from django.views.decorators.csrf import csrf_exempt
from api.forms import CreatePaymentForm
@method_decorator(login_required, name='dispatch')
@method_decorator(csrf_exempt, name='dispatch')
class PaymentView(View):
def post(self, request):
form = CreatePaymentForm(request.POST)
if form.is_valid():
pass
print("post: %s, errors: %s" % (request.POST, form.errors))
return HttpResponse(json.dumps({'errors': form.errors}),
status=400)
}}}
The output will be:
post: <QueryDict: {'amount': ['0.02']}>, errors: <ul
class="errorlist"><li>amount<ul class="errorlist"><li>Ensure this value is
greater than or equal to 0.02.</li></ul></li></ul>
