Field 'id' expected a number but got (something with Id) - django

Question

I am using Django 3.2.6
class FeedbackForm(CreatedMixin,
CommentMixin,
FlagMixin,
models.Model):
name = models.CharField(blank=False,
default="",
null=False,
unique=False,
max_length=500,
verbose_name=gettext("Name:"))
email = models.EmailField(blank=True,
default="",
null=False,
unique=False,
verbose_name=gettext("Email:"))
phone = PhoneField(blank=True,
default="",
null=False,
unique=False,
verbose_name=gettext("Phone:"))
message = models.TextField(blank=False,
default="",
null=False,
verbose_name=gettext("Message:"))
def __str__(self):
return f"{self.name}_{self.email}_{self.phone}"
class FeedbackForm(ModelForm):
class Meta:
exclude = [OmnibusNames.COMMENT.value,
OmnibusNames.FLAG.value,
OmnibusNames.CREATED.value,]
model = FeedbackForm
class FeedbackFormView(FormView):
template_name = 'feedback_forms/feedback_form.html'
form_class = FeedbackForm
class FeedbackFormResult(View):
def post(self, request, *args, **kwargs):
feedback_form_model = apps.get_model(app_label="feedback_forms", model_name="FeedbackForm")
new_feedback = feedback_form_model(request.POST)
new_feedback.save()
return render(request, template_name="feedback_forms/feedback_form.html")
<form id="subscription-form" onsubmit="return false">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Submit">
</form>
The problem:
{TypeError}Field 'id' expected a number but got <QueryDict: {'csrfmiddlewaretoken': ['W8wfxQvsmQyElPtsdmJFiDJmzbyKZXRYfZS9TAbFGpNZDo22jWaLotUrllHYsDWi'], 'name': ['John'], 'email': ['tad#gmail.com'], 'phone_0': ['[phone]'], 'phone_1': [''], 'message': ['ddd']}>
Something with id. But I thought that Id is auto-incremented. What can I try to resolve this?

Only a form can process the request.POST, so you should not create a model with request.POST but a form:
from app_name.forms import FeedbackForm
from django.shortcuts import redirect, render
class FeedbackFormResult(View):
def post(self, request, *args, **kwargs):
form = FeedbackForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return redirect('name-of-some-view')
return render(request, 'name-of-some-template.html', {'form': form})
I would strongly advise not to give a model and form the same name, that makes not much sense anyway.
Furthermore it might make more sense to work with a FormView [Django-doc] which will implement most of the boilerplate logic.
