Error when trying to write to database Django - django

Question

I am still learning Python via Django and have been doing most of my methods in views. I have been told that it is better practice to put them in my models under a Manager. I have the following code grabbing the product info and I believe the id to fill my model. but its throwing an error. Any help would be great.
Updated error after moving stuff in to model. Now it does't regonize request.session
Traceback:

Html matters
<form class="" action="{% url 'blackbelt:create' %}" method="post">
{% csrf_token %}
<p>Product: <input type="text" name="product" value=""></p>
<input type="submit" name="" value="Create">
</form>
view.py that matters
def create(request):
viewsResponse = Myblackbelt.objects.add_product(request.POST)
return redirect ('blackbelt:index')
Models in full
from __future__ import unicode_literals
from django.db import models
from ..logReg.models import User
class ProductManager(models.Manager):

secreteid= User.objects.get(id=request.session['loguser_id'])
Myblackbelt = self.create(product = postData['product'], creator=secreteid)
class Myblackbelt(models.Model):
product = models.CharField(max_length = 70)
created_at = models.DateTimeField(auto_now_add = True)
updated_at = models.DateTimeField(auto_now = True)
loguser = models.ManyToManyField(User, related_name='loguser')
creator = models.ForeignKey(User, related_name='creator')
objects = ProductManager()

Your code is not well structure and it'll break soon. However, to overcome the MultiValueDictKeyError error write these:
# views.py
def create(request):
if request.method == 'POST':
viewsResponse = Myblackbelt.objects.add_product(request.POST)
secreteid= User.objects.get(id=request.session['user_id'])
return redirect ('blackbelt:index')
class ProductManager(models.Manager):
def add_product(self, postData):
# always set a default value if dict key is not found
# of course you must (also) check if postData is of type dict
product = postData.get('product', None)
creator_id = postData.get('loguser_id', None)
if product is not None and creator_id is not None:
creator = User.objects.get(id=creator_id)
Myblackbelt = self.create(product=product, creator=creator)
print 'dog here'
