model = Sell NameError: name 'Sell' is not defined - django

Question

I am getting the error NameError: name 'Sell' is not defined But I have defined this Model in Models.py
Plz, tell what is the error I have posted my relevant code. Thanks in advance.
Models.py of buy app
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
class Sell(models.Model):
Cats =(
('Course book','Course book'),
('Fiction','Fiction'),
)
Lang =(
('Hindi','Hindi'),
('English','English'),
('Tamil','Tamil')
)
Cond = (
('New','New'),
('Old','old')
)
Title = models.CharField(max_length=400)
Author = models.CharField(max_length=100)
Price = models.DecimalField()
Category = models.CharField(choices=Cats)
Language = models.CharField(choices=Lang)
Condition = models.CharField(choices=Cond)
user = models.ForeignKey(User, on_delete=models.CASCADE)
Views.py of buy app
class sell(TemplateView):
template_name = 'buy/sell.html'
def get(self,request):
form = sellForm()
return render(request,self.template_name,{'form':form})
def post(self,request):
text = None
form = sellForm(request.POST)
if form.is_valid():
print("all good")
text = form.cleaned_data['Title']
form = sellForm()
args = {'form':form,'text':text}
return render(request,self.template_name,args)
Forms.py of accounts app
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserChangeForm
class EditProfileForm(UserChangeForm):
class Meta:
model = User
fields =(
'first_name',
'last_name',
'email',
'password'
)
class sellForm(forms.ModelForm):
Cats =(
('Course book','Course book'),
('Fiction','Fiction'),
)
Lang =(
('Hindi','Hindi'),
('English','English'),
('Tamil','Tamil')
)
Cond = (
('New','New'),
('Old','old')
)
Title = forms.CharField()
Author = forms.CharField()
Price = forms.DecimalField()
Category = forms.ChoiceField(required=False,choices=Cats)
Language = forms.ChoiceField(choices=Lang)
Condition = forms.ChoiceField(choices=Cond)
Description = forms.CharField()
class Meta:
model = Sell
fields = ('Title','Author','Price','Category','Language','Condition','Description')
Sell.html
<form method="POST">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Submit</button>
I didn't use Django UserCreateForm
I created it in this way in another app named accounts :
Views.py of accounts app
def register(request):
if request.method =='POST':
first_name = request.POST['first_name']
last_name= request.POST['last_name']
username= request.POST['username']
password1 = request.POST['password1']
password2 = request.POST['password2']
email = request.POST['email']
if password1 == password2:
if User.objects.filter(username=username).exists():
messages.info(request,'Username taken')
return redirect('register')
elif User.objects.filter(email=email).exists():
messages.info(request,'email exists')
return redirect('register')
else:
user = User.objects.create_user(username=username,password=password1,email=email,first_name=first_name,last_name=last_name)
user.save()
messages.info(request,'user created')
return redirect('login')
else:
messages.info(request,'password not matching')
return redirect('register')
return redirect('/')
else:
return render(request,'buy/register.html')

You just need to import the model
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserChangeForm
from .models import Sell
