Anyone here?
I was wondering if anybody is up for a collaborative project using DJango. It'll be great learning from each other.

I could do with a hand on something i’m making.. currently using tornadoweb but i’ll happily convert it over to Django if you want @YiiKuoChong
looking for all the help we can get in any area
@mikeleg can you be more specific?

@sam-aldis Are you sure? I don't want to be bothersome. I have no understanding in Tornadoweb so I can't help you convert it to DJango.

@YiiKuoChong yeah i’m sure.. Tornadoweb is really easy to get your head around.. in fact you might even prefer it to Django but i’m looking for all the help I can get and if that means converting it to Django thats not a problem at all :)

Hi, I'm trying to create a digital marketplace site where users will be able to register and submit their products.
I created the Product model and connected it with User with foreign key.Everything seems to be alright, but when I submit my product i get the following error:

null value in column violates not-null constraint
it looks like relation between product and user is not properly configured(regardless of my mixin that is suppose to handle it)

note that I'm using:
database : postgresql
allauth(for user registration)

from django.conf import settings
from django.db import models
from django.db.models.signals import pre_save, post_save
from django.core.urlresolvers import reverse
from django.utils.text import slugify
# Create your models here.

class Product(models.Model):
   seller = models.ForeignKey(settings.AUTH_USER_MODEL)
   #user = models.OneToOneField(settings.AUTH_USER_MODEL)
   # user = models.ForeignKey(settings.AUTH_USER_MODEL)
   # managers = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name="managers_products", blank=True)
   title = models.CharField(max_length=30) #owiuerpoajsdlfkjasd;flkiu1p3o4u134123 ewjfa;sd
   slug = models.SlugField(blank=True, unique=True)
   description = models.TextField()
   price = models.DecimalField(max_digits=100, decimal_places=2, default=9.99, null=True,) #100.00

   def __unicode__(self): #def __unicode__(self):
      return self.title

from django.views import View
from django.views.generic import (

from .forms import ProductModelForm
from .mixins import FormUserNeededMixin
# Create your views here.

class ProductCreateView(FormUserNeededMixin, CreateView):
    form_class = ProductModelForm
    template_name = 'create_view.html'

from django import forms

from django.utils.text import slugify

from .models import Product

class ProductModelForm(forms.ModelForm):
   class Meta:
      model = Product
      fields = [

from django import forms
from django.forms.utils import ErrorList

class FormUserNeededMixin(object):

     def form_valid(self, form):
        if self.request.user.is_authenticated():
            form.instance.user = self.request.user
            return super(FormUserNeededMixin, self).form_valid(form)
            form._errors[forms.forms.NON_FIELD_ERRORS] = ErrorList(["User must be logged in to continue."])
            return self.form_invalid(form)
