Because I used same client key and secret key same in another demo Django project, it works fine for that. in google cloud platform redirect URL is -- http:localhost:8000/oauth/complete/google-oauth2/ How to fix these? -

How to implement Angular with Django
I have requirement for creating an application using Angular(TypeScript) as frontend and Django as Backend, where I will be working only on Django (backend). Is that creating an REST API only enough to communicate with front end. Is that only possible in the backend in this case? Normally while working in Django I used to work in forms, views and will renders in the html and create API for it but in this case where I have no idea how angular would work even.

Custom Serializer for Django Rest Framework
I'm searching for a solution to create a serializer / API Endpoint to represent data in a custom order. When adding serializers and viewsets to DRF, I only get the fields associated with that Model. But what I like to have is a custom structure of all my models together. As an example: I have a model called season, a model called evenings and a model called events. Now I'd like to have an API Endpoint to have that all together, like so: { "requestTime": "2021-11-09 08:20", "requestURL": "/all", "requestMethod": "GET", "responseCode": 200, "season": "2021/2022", "evenings": [ { "evevning_id": 0, "day": "", "date": "2021-11-11", "event_count": 2, "events": [ {}, {} ] } ] } For data structure in the models I have some ForeignKeys like: season | evening | event Any suggestions how to achieve this? -

Is partial form a good practice in Django?
I'm new in Django and I try to find out if saving partial forms is a good practice or not. For example, I have Poll App and Candidate model with four fields: name, surname, targets andbiography. And I have a form where I have to fill all these fields. But if user only finished fill name, surname and targets, but even din't start filling biography field, how can I save his draft to user can finish it later and don't make any security mess?

How to save model in Django with unique but null fields
How can I save a model that should be unique but also allowed to be null in Django. For instance I have the following model... class PetOwner(models.Model): """Model representing a pet owner.""" user = models.OneToOneField(User, on_delete=models.CASCADE) first_name = models.CharField(max_length=50, help_text="Enter owner's first name") last_name = models.CharField(max_length=50, help_text="Enter owner's last name") email = models.EmailField( max_length=50, blank=True, unique=True, help_text="Enter owner's email" ) phone_number = models.CharField( max_length=15, blank=True, unique=True, help_text="Enter owner's phone number" ) address = models.ForeignKey( "Address", on_delete=models.SET_NULL, null=True, blank=True ) I want my app to work the following way. A PetOwner can sign up but when they do they initially only sign up with a username, password, a confirmation password, and first_name, and last_name. I want my to have a profile page which will allow for updating the PetOwner to include their phone_number but I do not necessarily want to make this a requirement. I decided that I'd make phone_number field null=True and blank=True but as soon as I register a second user I get a django.db.utils.IntegrityError: UNIQUE constraint failed: app_petowner.phone_number error. I believe it is because when I register a user for some reason instead of phone_number being None even when I did not actually add a phone number at … -
how to upload multiple images properly
I have a simple model which has four different fileFields for uploading different files and images. this is my models: class DocumentInfo(models.Model): id = models.AutoField(primary_key=True) certificate = models.FileField(upload_to="documents", null=True) id_card = models.FileField(upload_to="documents", null=True) service_certificate = models.FileField(upload_to="documents", null=True) educational_certificate = models.FileField(upload_to="documents", null=True) users need to simply upload some images in four individual fields so, I created a simple form and passed it to views like this: class DocumentForm(forms.ModelForm): class Meta: model = DocumentInfo fields = ['certificate','id_card','service_certificate','educational_certificate'] views.py: def document_info(request): if request.method == 'POST': form = DocumentForm(request.POST, request.FILES) if form.is_valid(): form.instance.user = request.user form.save() return redirect('document') if 'delete' in request.GET: return delete_item(DocumentInfo, request.GET['id']) else: form = DocumentForm() documents = DocumentInfo.objects.filter(user=request.user) context = { 'form': form, 'documents': documents, } return render(request, 'reg/documents.html', context) it works just fine at first but I cant reupload anything! the uploaded image neither gets saved the second time around nor deleted. what am I doing wrong? -

This how I designed the model: from django.db import models # Create your models here. from django.contrib.auth.models import AbstractUser class Event_type(models.Model): """ Event_type is like a category model for patient, datebase relationship is one to many """ name = models.CharField(max_length=40) class Meta: verbose_name = "event_type" verbose_name_plural = verbose_name def __str__(self): return self.name class Patient(models.Model): patient_id = models.AutoField(unique=True, primary_key=True) # patient identification patient_name = models.CharField(max_length=30, blank=True, null=True, verbose_name='patient_name') event_type = models.ForeignKey(Event_type, on_delete=models.CASCADE, blank=True, verbose_name='event type') event_value = models.PositiveIntegerField(default=0, verbose_name='even value', blank=True) event_unit = models.CharField(max_length=100, blank=True, verbose_name='event unit') event_time = models.DateTimeField(auto_now=True, verbose_name='event time') class Meta: verbose_name = 'Patient' verbose_name_plural = verbose_name ordering = ['-patient_id'] def __str__(self): return self.patient_name However I guess while loading the data into database I may have the ununique error.

Django Session Form (save form temporarily)
I have created a page for review form. All users can fill out the form, but only logged in users can submit the form. If users is not logged in, they will be redirected to the login page. After they login, they will be redirected to the profile page. So the flow will be like this : User fills out the form > click the submit > redirected to login page > user login and redirected to profile page (at the same time, the form they have filled in is automatically saved) I want the form they have filled in automatically saved after they login. How to do that? My idea is to create a session that saves the form temporarily, then save to database after they login. But I'm confused how to write the code Can anyone explain a bit what a django session is like? and how to write code to handle this problem? -

Here's my test: def test_GetUserAgenda(self): request_url = f'Agenda/get_user_agenda/' view = AgendaViewSet.as_view(actions={'get': 'retrieve'}) request = self.factory.get(request_url, {'id_user': 15}) response = view(request) self.assertEqual(response.status_code, 400) Note that: self.factory = APIRequestFactory() Am I missing something? Sincerely, -

use for loop with JavaScript template literal function
I have a web app, frontend using normal HTML5, backend using Django. In the frontend page, I have a JavaScript template literal function. Which is supposed to render all the individual value into a selection box of a queryset passed from backend to a bootstrap table. view.py: def view_material(request): query_results_publisher = Publisher.objects.all() return render(request, 'material/index.html', context={'Publisher':query_results_publisher}) index.html(bootstrap table + javascript template literal function): ... <th class ='publisher' data-field="book.publisher" data-formatter="renderPublisher">Publisher</th>... <script> var Publisher = "{{ Publisher }}"; var publisher = ''; function renderPublisher(value) { return `select style="width: 7em" name="" id=""> for (publisher in ${Publisher}) { <option value="eText" ${(value === 'eText') ? 'selected="selected"' : ""}> publisher</option>}</select>}` </script> But my for loop in javascript template literal function is not working, seems like I have some problem with the template literal usage in for loop. How to correct my function?
