you could have a field "parent" in your Model Category which is a
ForeignKey to Category itself, so Category is a self-referencing table.
Then in your first dropdown you only show those entries where parent is
None and in your second one where parent == accessories.
you need to get this right

the form doesn't know the request only the view does. how does your view
function look like?

needs to go inside of the __init__ function. you pass user = request.user
as a parameter to OrderTestForm when you instantiate it in your view and
can use it then in your init function.
Also you can only filter the id of the author if the author

setting default=False is odd for any field other than a BooleanField. I
would take that out for the OneToOneField at least and see how things go.

It sounds like your database is empty. Did you check if there are any
Question records in your admin view? Under
127.0.0.1:8000/admin
You should see an entry for Questions and you can create question
records there.
Here they describe, how to create those records using the django
management
with a Foreign Key field, one-to-many relationship:

Hi, I think in your view modulesView() you need to pass the project id to
ModuleForm:
..
else :
form = ModuleForm(projectid)
..
and then you need to overwrite the constructor of ModuleForm by adding an
__init__ function:
def __init__(self, projectid=None, *args, **kwargs):
I think you can use some basic template language within a script block like
below. myData is a stringified json object, that worked for me.

{% if myData %}
var table_data = {{ myData|safe }};
{% else %}
var table_data = null;
{% endif %}

Hi Aniket,
Your thread object in your template is actually a message since your
passing messages to context in your view.
but when you initialize messages you don't set a name attribute.
So I would double check your Message model if it has a name attribute.
btw your error message didn't
Hi,
It sounds like you don't get an error message, so maybe your authenticate
method in

your setup:
Couldn't you also set up cron jobs to check for some conditions you have
to come up with, which are using the fields of your User model like
date_joined and check, if fields of your user profile are filled in with
respect to the created date of your profile?
I would start with writing some django
Hi Kushal,
Since the out-of-the box User model is coming from the auth module, you
can hardly extend this class. To store additional information for
different types of Users, you could create a custom UserProfile model,
which has a Foreign Key to the User model:
from django.db import models

Hi Chuck,
Status in your example is not a text field, but a Foreign Key, that
means a reference to a record in another table Task_Status, you see that
here:
Status = models.ForeignKey(Task_Status, on_delete=models.CASCADE)
You need to filter on the attribute within Task_Status, which has
