I have issues with the following code in my Django project.
Anyone one have a clue what's wrong?
Exception Type: TypeError at /tasks/2/3/ Exception Value: int() argument must be a string, a bytes-like object or a number, not 'DeferredAttribute'

next = ""
if int(Step.step_number) < len(steps):
next = "/%s/%s/" % (task_pk, int(step_pk) + 1)
user.userprofile.current_step.update(step_pk)
else:

I am facing an error from this Django project. I have tried all the advice i can come across still its not working properly.
Below is the error from the web.

Exception Type: TypeError at /login
Exception Value: Strings must be encoded before hashing
As error message clearly says, you have to encode the password first.
In main/views.py on line 171 you have
hashed = bcrypt.hashpw(request.POST['login_password'], bcrypt.gensalt())
Your request.POST data is a string, so you should encode it to bytes:
hashed = bcrypt.hashpw(request.POST['login_password'].encode(), bcrypt.gensalt())
You can select other encoding (not default utf8) with .encode('ascii') (choose one and don't change it later, utf8 is probably the best choice in general).
I want to add a Sessions tabs to my Django project:
navbar.html
<li>Sessions</li>
But i keep getting the following error:
'User' object has no attribute 'session_set''User' object has no attribute 'session_set'
Exception Location: C:\Users\User\lib\site-packages\django\utils\functional.py in inner, line 214
I don't know where this error comes from, i did not find any other reference online, can anyone help me?
Here is the login view that i'm using: https://github.com/Bouke/django-two-factor-auth/blob/master/two_factor/views/core.py

You need to replace django.contrib.sessions in your INSTALLED_APPS with user_sessions if you want to use django-user-sessions. This will setup its models correctly.
Furthermore make sure you have also followed all other installation instructions.
when i tried to run a piece if code in my django application i have been faced with some strange error
def main(request):
async def hello(request):
ws = web.WebSocketResponse()
await ws.prepare(request)
msg="this is awesome"
ws.send_str(msg)
# return HttpResponse("ok")
loop = asyncio.new_event_loop()
asyncio.set_event_loop(loop)
loop = asyncio.get_event_loop()
loop.run_until_complete(hello(request))
loop.close()

I haven't touched the code on my app in weeks but i'm suddenly getting this exact same TypeError on every page, including Admin pages.
The last thing to happen was an update on a model to change a ForeignKey field, but I don't feel the two are related

Exception Value: 'NoneType' object is not iterable
Solved it by looking through some of my own context processors. I had one function that was returning None on a request (after changing an entry and having an empty queryset as a result).
I'm trying to verify if a value exists in my database with:
q = model.objects.filter(field__iexact='1')
But this makes an error in Django, which returns this message:
DoesNotExist at /answer_survey/
Model matching query does not exist
