not able to createsuperuser in django

I am not able to createsuperuser, I am getting the following error

basically its throwing

I read this alsoSO-related question I don't get it exactly as conveyed there.

Settings.py
# Swapping the user model
AUTH_USER_MODEL = 'mainapp.User'
Please clarify, what am I missing ...

You need to add the UserManager to the User mode:
class User(AbstractUser):
# …
objects = CustomUserManager()
Without specifying the manager, it will fallback to the UserManager [Django-doc], not the CustomUserManager.

Here is my models.py:
class PostComments(models.Model):
post = models.ForeignKey(InfoPost, on_delete=models.CASCADE, related_name='comments')
author = models.ForeignKey(User, on_delete=models.CASCADE, related_name="username")
text = models.TextField()
created_date = models.DateTimeField(default=timezone.now)
#approved_comment = models.BooleanField(default=False)
reply_to = models.ForeignKey("self", null=True, blank=True, on_delete=models.CASCADE, related_name='replies')
#def __str__(self): return 'Comment by {} on {}'.format(self.name, self.post)
I am trying to make comments system for post in my website, but there is some error occured. I don't know whats wrong with my model, but if i try to make migrations without my new PostComments model, its migrating pretty fine.
UPD. Here is my code, where i am using my PostComments model
forms.py
class CommentsForm(forms.ModelForm):
post = forms.CharField(required=False)
author = forms.CharField(required=False)
class Meta:
model = PostComments
fields = '__all__'
views.py
def post(request, slug):
post = get_object_or_404(InfoPost, slug=slug)
comment_list = CommentsForm._meta.model.objects.all()
if request.user.is_authenticated:
user = User.objects.get(username=request.user.username)
if request.method == 'POST':
comment = CommentsForm(request.POST)
print(comment.is_valid())
if comment.is_valid():
com = comment.save(commit=False)
com.author = request.user
com.post = post
com.save()
return redirect('post', slug=slug)
else:
comment_form = CommentsForm()
return render_to_response('MainPage/Post.html',
{'post': post, "user": user, 'img_w': image_w, 'img_h': image_h,
'comments_list': comment_list, 'comment_form': comment_form})
return render_to_response('MainPage/Post.html', {'post': post, 'img_w': image_w, 'img_h': image_h, 'comments_list': comment_list})
I was thinking, its started after i tried to get all objects of comments for displaying them in view, but i don't really know

You are shielding the actual username field on the User model with the related_name on the author ForeignKey.
It should be like this:
author = models.ForeignKey(User, on_delete=models.CASCADE, related_name="usernames")
'related_name=usernames' at plural.
The reason why it failed is because when you did:
user = User.objects.get(username=request.user.username)
you were basically accessing the reverse relation to the comments set that are tied to the user, not the actual username field (which I assume is a CharField).
More info about related_name in the django documentation.

I don't understand why you have set post and author to CharFields, when the model has foreign keys. Especially as you are setting then directly in the model anyway.
You should remove those definitions, and then exclude the fields from the form altogether:
class CommentsForm(forms.ModelForm):
class Meta:
model = PostComments
exclude = ("post", "author")

If you can provide any help I would greatly appreciate it.

field=models.IntegerField(default=0),
),

Obviously in it's first version your UserProfile's "phone" field was a CharField defaulting to the empty string. Changing an existing field's type requires a three-steps migrations: first create a new field with the desired type, create and apply the migration, then create a datamigration that will copy original data to the new field with proper transformations, error handling etc, and finally delete the original field (create and apply the migration).
BUT : in your case, making this field an integer is just plain wrong. A phone number is NOT an integer. First because you cannot add, substract, multiply or divide phone numbers, then because a phone number can contain non-numeric characters too (cf international phone numbers formats).
Thinking that everything made of numeric characters should be an int is a common beginner mistake (just like using floats instead of decimals for prices storage and calculations). When in doubt, ask yourself whether applying mathematical operations would make sense...

Is it because of improper jwt token configuration or user model?

Have you tried retrieving your User model with get_user_model?

Django Boolean Field used in view.py

I am trying to add a feature to where a new user needs to update his/her password on an initial login. I added a hidden BooleanField to my Profile model where default = True.
models.py
class UserProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
force_password_change = models.BooleanField(default=True)
However, when trying to use force_password_change in my views.py, it never returns the correct value that I set in django's admin page.
views.py
if request.method == 'POST':
...
user = authenticate(request, username=username, password=password)
changepass = UserProfile.objects.get(user=request.user)
if user:
if changepass.force_password_change == True:
changepass.force_password_change = False
changepass.save()
return HttpResponseRedirect('/login/register/')
elif changepass.force_password_change == False:

in manager_method
return getattr(self.get_queryset(), name)(*args, **kwargs)
File "C:\Python34\lib\site-packages\django\db\models\query.py", line 380, in

self.model._meta.object_name
start.models.DoesNotExist: UserProfile matching query does not exist.
I also added AUTH_PROFILE_MODULE = 'start.UserProfile' to my settings.py, so that does not seem to be the problem.

You are forgetting to create UserProfile with the respected user
from django.db.models.signals import post_save
from models import UserProfile
from django.contrib.auth.models import User
def register(request):
if request.method == 'POST':
uf = UserForm(request.POST, prefix='user')
upf = UserProfileForm(request.POST, prefix='userprofile')
if uf.is_valid() and upf.is_valid():
user = uf.save()
userprofile = upf.save(commit=False)
userprofile.user = user
userprofile.save() # Are you missing this line ??
return django.http.HttpResponseRedirect(…something…)

This has nothing to do with boolean fields. The error is telling you that your specific User does not have a related entry in the UserProfile table.
