Django - Save form fields while paging
This will be a lengthy post, please have patience with me, I just started with Django and try to wrap my head around it. I created a site that will go thru exam questions one at a time, displaying the question and the multiple choice answers like on countless other websites. The challenge I experience is when the user clicks "NEXT" on the pagination buttons, I would like for the selected answer(option) to be saved back to the database. I tried it with AJAX scripts but the view never got executed. Maybe there is a better way to do this or could you please point me into the right direction? I will post all of my code and hope someone can please assist me. Thank you for taking the time to look at this. I start with the models.py: from django.db import models class QuesModel(models.Model): question = models.TextField(null=True) code_snippet = models.TextField(null=True) op1 = models.CharField(max_length=200,null=True) op2 = models.CharField(max_length=200,null=True) op3 = models.CharField(max_length=200,null=True) op4 = models.CharField(max_length=200,null=True) ans = models.CharField(max_length=200,null=True) def __str__(self): return self.question class Answer(models.Model): ans_id = models.AutoField(primary_key=True) question_id = models.ForeignKey(QuesModel, on_delete=models.CASCADE) fname = models.CharField(max_length=50) lname = models.CharField(max_length=50) examdate = models.DateField(auto_now_add =True) answer = models.PositiveSmallIntegerField() def __int__(self): return QuesModel.question[self.question_id] template is home.html: {% … -
Target Specific Members of the User Class

Request Errors with fetch API
I'm trying to send data through a form with just one field to my Django API, then read and use the data received in the API for other things. I don't want to store the data, just use it. This is my react code: const handleSubmit = async (e) => { e.preventDefault(); try{ let res = await fetch(api,{ method: 'POST', headers: {'Content-Type':'application/json'}, body: { url: url, }, }); let resJson = await res.json(); if(res.status === 200){ console.log(resJson) setUrl(""); setMessage("Success"); } else{ setMessage("Error"); } }catch(err){ console.log(err); } }; This is my Django view.py @api_view(['POST']) def eda(request): response = { 'result': 'lalala', 'url':request.POST['body'], 'code': 'success' } return Response(response) I don't understand what's wrong, but I get bad request error or unsupported media type error. -
Using a custom model for Django Admin
I have a custom user model, which an admin model inherits: class User(AbstractBaseUser, PermissionsMixin): ... class Staff(User): is_staff = models.BooleanField( _("staff status"), default=True, help_text=_("Designates whether the user is staff"), ) ... class Admin(Staff): is_admin = models.BooleanField( _("staff status"), default=True, help_text=_("Designates whether the user can log into this admin site."), ) ... As well as a custom backend for authorization class AdminBackend(ModelBackend): def authenticate(self, request, username=None, password=None, **kwargs): if username is None: username = kwargs.get(Admin.USERNAME_FIELD) if username is None or password is None: return try: user = Admin._default_manager.get_by_natural_key(username) except Admin.DoesNotExist: # Run the default password hasher once to reduce the timing # difference between an existing and a nonexistent user (#20760). Admin().set_password(password) else: if user.check_password(password) and self.user_can_authenticate(user): return user ... However, I am unable to log in due to has_permission in admin/sites.py Is there a way to avoid registering a custom site, as that will increase complexity? -
Django : Getting the image URL of elements in a table that has a many-to-one relationship with another table
I have an Event model that is linked to other tables with foreign keys.

Handle divide by zero with aggregated fields in Annotate expression

Is there a way to reload a Django template screen using the previous request data to an API call?
I built a simple weather app utilizing the OpenWeatherMap API using Python/Django and Django Templates for the client side. I created a refresh button in the <div class="info-grid"> using an <a href="{{ request.get_full_path }}"> and <img> tag, which is intended to refresh to the most current weather information for the currently queried city, but when I click on it, it refreshes the page and shows the weather info for the default city, which I set it to 'Chicago' in views.py.

DRF Grant Type Convert Token
I'm trying to implement an authentication system in my Django backend through the Oauth2 protocol. Also, I'm using the drf_social_oauth2 lib. However, I'm having a hard time understanding how I can reproduce the auth system in Postman. Postman offers some auth flows (Grant Types) which greatly facilitates the authentication process. However I came across an authentication flow I've never heard of ( convert_token ). I wish to use the oauth2 system to authenticate using the Facebook Provider, but its not clear for me the flow to validate this in Postman. this is the snippet of code send to validate the access token in react: import axios from 'axios'; import { useHistory } from 'react-router-dom'; const facebookLogin = (accesstoken) => { console.log(accesstoken); axios .post('http://127.0.0.1:8000/auth/convert-token', { token: accesstoken, backend: 'facebook', grant_type: 'convert_token', client_id: '05GYopkyMDxFakgCSuNtpOLrNcyJwU054wZfYBt1', client_secret: 'U3r3rmtff7t52Xa1chfzGf5vtl06zr4PwGbi8sWBcilTKs0YJEm278JPmXbcgMsyYpxYMQbDKFsyjhrzKwDLW8VMfW0ePZmrRuSmssnFPvqjeodYsNTfObTAzxOxZKuH', }) .then((res) => { localStorage.setItem('access_token', res.data.access_token); localStorage.setItem('refresh_token', res.data.refresh_token); }); }; export default facebookLogin; I am expecting to do the same into Postman -

Fitting rows and columns in the same table so they line up nicely
I would like to use two different <thead>'s in the same table but i want them stacked nicely. The way it is now, the first heading has 1 less column then the 2nd one so it looks funky. If there is a way to expand that first heading out so that there isnt a space to the right of it, that would be great. Or maybe you know of a better way of tackling this problem. Here is how the table looks right now. and here is the code that i am using to get this result <div class="hidden" id="part-req-section"> <form method="post" name="partForm" id="partForm"> {% csrf_token %} <div class="row"> <div class="container"> <div class="row"> <div class="container"> <div class="table-responsive"> <h3>Part Request</h3> <table class="table table-bordered table-hover table-responsive"> <thead> <tr> <th scope="col">Part name*</th> <th scope="col">Quantity*</th> <th scope="col">Reason*</th><br> </tr> </thead> <tbody id="part-req-form-list"> {{ part_request_formset.management_form }} {% for some_form in part_request_formset %} <tr id="part-req-form" class=""> <td>{{ some_form.part|as_crispy_field }}</td> <td>{{ some_form.quantity|as_crispy_field }}</td> <td>{{ some_form.reason|as_crispy_field }}</td> <tr> {% endfor %} <thead> <tr> <th scope="col">Aisle*</th> <th scope="col">Column*</th> <th scope="col">Shelf*</th> <th scope="col">Bin*</th> </tr> </thead> <tr> <td>{{ location.aisle|as_crispy_field }}</td> <td>{{ location.column|as_crispy_field }}</td> <td>{{ location.shelf|as_crispy_field }}</td> <td>{{ location.bin|as_crispy_field }}</td> </tr> <tr id="empty-part-req-form" class="hidden"> <td>{{ part_request_formset.empty_form.part|as_crispy_field }}</td> <td>{{ part_request_formset.empty_form.quantity|as_crispy_field }}</td> <td>{{ part_request_formset.empty_form.reason|as_crispy_field }}</td> … -
Nextjs With Django Content Security Policy (CSP)
In a project where Nextjs is used as a frontend and Django is used as a backend api, where should the Content Security Policy (CSP) be set? Ive seen in examples that csp rules can be set in nextjs in the next config file and in django it can be set in the settings.py I am still trying to wrap my head around csp and security related things in general. Not sure if this matters but I am not using the api features in Nextjs, only django as an api. -

Implement a simple task management system which require APIs to :
Create tasks with fields *Title (title of task), *Description (any notes or details), *Status (1:open/not done, 2: done; default is 1), *Assigned To (user id to which task is assigned). Update status of task (1: not done, 2: completed) List users who completed all tasks Sort users list in the order of task completion Assumptions for create task API: Add some users with name, id, phone number to the database. No need for user insertion via code. You can assign multiple tasks to a user but maximum 3 tasks should be assigned in a day for a user. I didn't get the update status...
