Django assign "score" to each "user" - python

I am trying to practice my skills with django as a beginner, I built this platform with users and quiz. If logged in, the user can take a quiz. My goal here is to print on the "user profile" page the scores of the tests he/she has taken. Do you have any suggestions on how I can link the score to the user? Or do you have any resource to follow?

Maybe use a model to store user, questions and score is a good start.

I am trying to make quiz making application, since am new to django am unable to build the logic for saving foreign key field in database table. Someone please help me for the same.
models.py
In models.py , class quiztitle is for title of the quiz and id(foreign key,User model) of user who created that quiz.
class question is for question along with 4 options and the correct answer. Quizid(foreign key,quiztitle model) and id(foreign key,User model)
class answer is for the answer submitted by user who take the quiz.

admin.site.register(quiztitle)
As you guess your issue lies at title and detail.
To set a value to the ForeignKey you need an object. You can use instead an field with _id at the end.
Behind the scenes, Django appends "_id" to the field name to
create its database column name, see Django ForeignKey
It must be:
title = quiztitle.objects.create(
Quiz_title=Quiz_title,
Quiz_id=Quiz_id,
User_id_id=id # here
)
detail = question.objects.create(
Quiz_id_id=Quiz_id, User_id_id=id # and here,
Qid=Qid, Qques=Qques, Qoption1=Qoption1,
Qoption2=Qoption2, Qoption3=Qoption3,
Qoption4=Qoption4, QAnswer=QAnswer
)
I suggest you to use Django ModelForm here.
Based on the above, I recommend you also to rename your ForeignKey fields:
id > to user
Quiz_id > to quiztitle
Model style (Django Docs):
Use InitialCaps for class names (or for factory functions that return
classes).
Field names should be all lowercase, using underscores instead of
camelCase.

I have no clue what I changed to make the admin site not work - any help gratefully received!
Check your ROOT_URLCONF setting - it needs to be set to myproject.urls but looks like it is currently set to product_app.urls.

For creating forms I used Django built-in forms,I had to create one for adding albums and another for adding the album's songs
Here is my album_form.html screenshot
and here is my form-template.html screenshot:
and here is my song_form.html screenshot
In the form_valid method, you should fetch the album pk from the url kwargs and set the album on the form instance.
from. django.shortcuts import get_object_or_404
class SongCreate(CreateView):
model = Song
fields = ['song_title', 'file_type']
def form_valid(self, form):
album = get_object_or_404(Album, pk=self.kwargs['pk']
form.instance.album = album
return super(SongCreate, self).form_valid(form)

Django - How to allow only the owner of a new post to edit or delete the post?

I will be really grateful if anyone can help to resolve the issue below.
I have the following Django project coding. The problem is: when the browser was given "/posts/remove/<post_id>/" or "/posts/edit/(<post_id>/" as the url, it will allow the second user (not owner) to perform the remove and edit jobs, respectively.
How can I allow only the owner of a new post to edit or delete the post?

Add request.user == item.user check inside your method.

def post_remove(request, post_id):

Issue with custom user registration in django

I am using python and django to develop an web application where I have built a CustomUser model extending the user model and also built a sign up form. But problem is that each time I am registering a new user when I go back to login page and enter the user name and password, it keeps giving the message "Username and Password does not match".
I am pasting the codes here:
forms.py
import re
from django.utils.translation import ugettext_lazy as _
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm, UserChangeForm

"""A form for creating new users. Includes all the required
fields, plus a repeated password."""
first_name = forms.RegexField(regex=r'^\w+$', widget=forms.TextInput(attrs=dict(required=True, max_length=30)), label=_("First name"), error_messages={ 'invalid': _("This value must contain only letters") })
last_name = forms.RegexField(regex=r'^\w+$', widget=forms.TextInput(attrs=dict(required=True, max_length=30)), label=_("Last name"), error_messages={ 'invalid': _("This value must contain only letters") })
password1 = forms.CharField(widget=forms.PasswordInput(attrs=dict(required=True, max_length=30, render_value=False)), label=_("Password"))
password2 = forms.CharField(widget=forms.PasswordInput(attrs=dict(required=True, max_length=30, render_value=False)), label=_("Password (again)"))
date_of_birth = forms.DateField(widget=forms.TextInput(attrs= {'class':'datepicker'}))
sex = forms.ChoiceField(choices=(('M', 'MALE'), ('F', 'FEMALE')), label=_("Sex"))
voter_id = forms.CharField(widget=forms.TextInput(attrs=dict(required=True, max_length=30)), label=_("Voter Id"))
is_election_staff = forms.BooleanField(initial=False, required=False)

Can anyone please suggest me the mistake that I am doing here? Thanks in advance.
Your Override the user model but have make change in backend.py which is use to check when user try to login in this file i think django checking username and password from user model.
