AdminPanel/views.py in this file I successfully created the user and stored the user data
def fixed_target_account(request):
if request.method == "POST":
form = ClientDetailsForm(request.POST, request.FILES)
try:
user = User.objects.create_user(request.POST['username'], password=request.POST['Mobile_no'])
user.save()
except IntegrityError:
return render(request, 'AdminPanel/fixed_target_account.html', {'form':ClientDetailsForm,'error':"Username is already been taken."})
if form.is_valid:
newform = form.save(commit=False)
newform.user = request.user
newform.save()
return redirect('AdminPanel:dashboard')
else:
return render(request, 'AdminPanel/fixed_target_account.html', {'form':ClientDetailsForm,'error':"Please enter the valid data."})
else:
pass
return render(request, 'AdminPanel/fixed_target_account.html')
Client/Views.py file here I want when user logs in his online status should be set to true [even though it is]
def loginuser(request):
''' code for logging in the user also when logged in update staus to active '''
if request.method == "POST":
user = authenticate(username=request.POST['username'], password=request.POST['password'])
login(request, user)
# get the id of the user
pk = request.user.id
ClientDetails.objects.filter(id=pk).update(online=True)
return redirect('Client:dashboard')
else:
return render(request, 'Client/loginuser.html')
when he sign's out his online status should be set to False I tried other ways and this as well but its not updating the status in backend [at admin side ]
def sign_out(request):
''' before logging out the user update his online status to False '''
pk = request.user.id
print(pk)
ClientDetails.objects.filter(id=pk).update(online=False)
logout(request)
return render(request, 'Client/loginuser.html')

Answer 1

Your ClientDetails model isn't actually linked in any way to the model that's used for your user authentication. This model is probably called something like User, although we can't be certain of that with the given information in the question.
When you fetch the id of the currently authenticated user from the request with request.user.id, this is actually referencing a User instance and not a ClientDetails instance. So the line ClientDetails.objects.filter(id=pk) will most likely either give you the wrong ClientDetails instance or none at all and thus update(online=True) will normally not updated the instance you expect it to update.
So you either have to link your ClientDetails with a foreign key to your User object and then use that link to query, or you can presumably use the username from the User instance and use that in your query on ClientDetails like so: ClientDetails.objects.filter(username=request.user.get_username()).
