data is stored on localhost but not on gae datasto

Question

For some reason, the form I created inserts data into the db on localhost. I deployed it to gae, the form works but nothing is been inserted into the datastore?

Here is my models file:

from django.db import models
# from django.contrib.auth.models import User

# Create your models here.
class Company(models.Model):
    id = models.IntegerField(primary_key=True);
    name = models.CharField(max_length=100, null=True);
    address = models.CharField(max_length=100, null=True);
    phone = models.CharField(max_length=15, null=True);
    website = models.CharField(max_length=50, null=True);
    email = models.EmailField(max_length=50, null=True);
    hiring = models.BooleanField(default=False);    
    latitude = models.DecimalField(max_digits=20, decimal_places=10, null=True);
    longitude = models.DecimalField(max_digits=20, decimal_places=10, null=True);
    approved = models.BooleanField(default=False);
    date_added = models.DateTimeField(auto_now_add=True);
    about_us = models.TextField(max_length=500, null=True);

My form:

from django import forms
from company.models import Company

class SignUpCompanyForm(forms.ModelForm):
    class Meta:
        model = Company;

My html form:

{% block content %} 
    <div id="content">
        <!-- a form for sign up -->
        <form id="sign" action="/sign_up_company" method="post">
            <table>{{ form }}</table>
            <input type="submit" value="Sign Up" />
        </form>
    </div>
{% endblock %}

My view function:

def sign_up(request):
    if request.method == 'POST':
        form = SignUpCompanyForm(request.POST);
        if form.is_valid():
            company = form.save(commit=False);
            company.save();
            # company.put();

    return HttpResponseRedirect('/confirmation');

The action of the form is mapped to "sign_up".

When I run "python manage.py syndb" I get:

C:\Users\Joe\Desktop\test>python manage.py syncdb

No fixtures found.

App Engine does not support Django models. You have to write your models using App Engine's db.models or ndb.models API.

The other option is to use Django-nonrel. It's a fork of Django 1.3 that works on App Engine or MongoDB. This will allow you to use Django models.

It's a bit odd that it's succeeding locally. Your Django setup must be configured to use some SQL database like SQLite, it's probably not actually writing to the dev_appserver datastore.
