form.py
class complaintForm(forms.ModelForm):

views.py
class CreateComplaintView(CreateView):
model = complaintForm
form_class = complaintForm
template_name = 'user/post_complaint.html'
success_url = 'success'

Answer 1

You passed your model to the form attribute. This is why ComplaintForm is not a good idea for a model name. You better rename this to Complaint for example:
class Complaint(models.Model):
user = models.ForeignKey(Profile, on_delete=models.CASCADE)
category = models.CharField(max_length=255,choices=complaints,default='Mess')
title = models.CharField(max_length=20)
content = models.CharField(max_length=100)
image = models.ImageField(upload_to='complaint_pics/')
def __str__(self):
return self.title
You will need to construct and run migrations to rename the table at the database side.
Then you thus define your form as:
from app.models import Complaint
class ComplaintForm(forms.ModelForm):
class Meta:
model = Complaint
fields = ['title','content','image',]
Finally in your CreateView, you can use:
from app.models import Complaint
from app.forms import ComplaintForm
class CreateComplaintView(CreateView):
model = Complaint
form_class = ComplaintForm
template_name = 'user/post_complaint.html'
success_url = 'success'
def form_valid(self, form):
form.instance.user = self.request.user.profile
super().form_valid(form)
Note: normally a Django models, just like all classes in Python are given a name in PerlCase, not snake_case, so it should be: Complaint instead of complaint.
