Refresh a django subtemplate with javascript
I'm trying to refresh a subtemplate by calling a view with js. Nothing seems to happen, though the server gets hit and seems to return a response. The goal is to refresh the included part without refreshing the whole page. Minimal example: views.py def ajax_view(request): context = {} context['data'] = 'data' return render(request, "test.html", context)// <-- reaches here, but no rendering test.html {{data}} main.html <script type="text/javascript"> function getQuery() { var request = new XMLHttpRequest(), method = 'GET', url = '/ajax/'; request.open(method, url); request.send(); } </script> {% include "test.html" %} // <-- does not update -

Django Google App Engine SQL db non-deterministically thinks a row does not exist
I have a Django backend server hosted on Google App Engine that uses a MySQL database. I am using Firebase (via the Pyrebase wrapper) to authenticate users. The following function is what I use to get the User object given a an auth-token that's stored in the request HTTP metadata. def user_from_request(request): refresh_token = request.META.get("HTTP_AUTHORIZATION") fb_user = auth.refresh(refresh_token) # Firebase user information. firebase_id = fb_user.get("userId") potential_user = User.objects.filter(firebase_id=firebase_id) if potential_user.count() == 0: print('auth token', refresh_token) print('firebase id', firebase_id) return None return potential_user.get() For the most part, it works fine, but there are some small cases (from what I can tell, it is non-deterministic which means it's been a pain to debug) when the auth token will exist in Firebase and we are able to get an associated Firebase id, but SQL (specifically the User.objects.filter(firebase_id=firebase_id) line will return an empty query set. The following is what is printed out when that case happens. auth token XXXXXX # changed to protect user information firebase id XXXXXX # changed to protect user information The strange part is is that there does exist a User row in the database where that Firebase id exists. Subsequent requests with the same auth token will successfully grab … -
Django Error refers to model that isn't installed after Updating

How to create an extended User Object in Django?
I created a model ExtendedUser to extend the User Django built-in model class using the approach described in the official documentation: https://docs.djangoproject.com/en/3.2/topics/auth/customizing/#extending-the-existing-user-model so that I can benefit from the existing authentication features provided by Django. That works all fine however I wonder now, whenever I want to create a new ExtendedUser, that means for every ExtendedUser, I also need to create an original User to fullfill the one-to-one relationship? Or what else does it mean the following: Assuming an existing Employee Fred Smith who has both a User and Employee model, you can access the related information using Django’s standard related model conventions[...] In a script to create objects, would this mean the following: u1 = User.objects.create_user(username="u_1", email="u_1@abc.com", password="pw_u_1") ext_u_1 = ExtendedUser.objects.create(id=u1.id, user=u1, prop_1="XYZ") where class ExtendedUser(models.Model): user = models.OneToOneField(User, ...) # More properties... -

But if I select choice#3 in question 1 and check checkbox#1 or checkbox#2 in question 2 then i get an error: CheckChoice matching query does not exist.

Django/DRF changing POST requests to GET
Whenever my frontend sends off a POST request to /api/notebooks/, Django automatically converts it to a GET request to /notebooks?name=[whatever I just typed in]. This isn't the case when I make POST requests to /api/notes/. Whenever I do, it creates a Note object and saves it to the database, the way it's supposed to. Did I mess up anything in my config? I'm 100% sure I've been shooting off my POST requests to /api/notebooks/ rather than /notebooks/... notebooks/urls.py from notebooks.views import NoteViewSet, NotebookViewSet from rest_framework import renderers notebook_list = NotebookViewSet.as_view({ 'get': 'list', 'post': 'create', }) notebook_detail = NotebookViewSet.as_view({ 'get': 'retrieve', 'put': 'update', 'patch': 'partial_update', 'delete': 'destroy', 'post': 'create', }) note_detail = NoteViewSet.as_view({ 'get': 'retrieve', 'post': 'create', 'put': 'update', }) core/urls.py from django.contrib import admin from django.urls import path, include from rest_framework.routers import DefaultRouter from notebooks import views router = DefaultRouter() router.register(r'notebooks', views.NotebookViewSet, basename='notebooks') router.register(r'notes', views.NoteViewSet, basename='notes') urlpatterns = [ # auth path('auth/', include('authentication.urls')), # notebook path('admin/', admin.site.urls), path('api/', include(router.urls)), # frontend path('', include('frontend.urls')), path('notebooks/', include('frontend.urls')), path('signup/', include('frontend.urls')), path('login/', include('frontend.urls')), path('notebooks/<slug:notebook_pk>/', include('frontend.urls')), path('notebooks/<slug:notebook_pk>/notes/<slug:note_pk>/', include('frontend.urls')), path('new-note/', include('frontend.urls')), ] notebooks/serializers.py import json from django.core.files.base import ContentFile from rest_framework import serializers from .models import Note, Notebook, User class NoteSerializer(serializers.ModelSerializer): note_id = serializers.SlugField(source='id', read_only=True, required=False) … -

Optimum Serializing in Django Rest Framework and parsing in Javascript
I am trying to adapt an event calendar vuejs module called dayspan calendar. Current entry object for an event as json is a bit strange and I want to balance the parsing of the payload before the post request and handling of data in DRF serializers. So I can get an optimum and performant client-server rest API communication. Json output is as below before any parsing: { "data": { "title": "YOK", "description": "", "location": "", "color": "#1976d2", "forecolor": "#ffffff", "calendar": "", "busy": true, "icon": "" }, "schedule": { "times": [ "17" ], "dayOfMonth": [ 11 ], "year": [ 2021 ], "month": [ 5 ] } } There are more schedule fields like "dayOFWeek", "duration" etc. that is to be expected for different entries. What would be the best approach in terms of parsing json payload before posting to DRF and in deserializing stage before saving into database? I appreciate any ideas. -

Here is the form: class ExamForm(forms.Form): def __init__(self, class_choices, teacher_choices,teacher, *args, **kwargs): super(ExamForm, self).__init__(*args, **kwargs) self.fields['classes'].choices=SchoolClass.objects.filter(school_id=teacher.school_id) I am getting SchoolClass objects for choices classes = forms.MultipleChoiceField(choices=(), widget = forms.CheckboxSelectMultiple, label = "Classes for this exam.") When I run my project it shows like that : Blank choice fields -
Django: ModuleNotFoundError with Foreign Keys
I'm running into an import error with foreign keys spanning across multiple apps within my Django project. Specifically, when I run any python manage.py command, I get: from project.weather.models import Ice ModuleNotFoundError: No module named 'project.weather' Here's the structure of project: weather/ apps.py models.py ... display/ apps.py models.py ... Here's what display/models.py looks like: from django.db import models from django.contrib.auth import get_user_model from project.weather.models import Ice class DisplayManager(models.Manager): pass class Display(models.Model): objects = DisplayManager() weather = models.ForeignKey(Ice, null=False, on_delete=models.CASCADE) INSTALLED_APPS in settings.py looks like this: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'weather', 'display', ] Any reason for this? I don't believe I have a circular import issue, but if I do that would explain why the ModuleNotFoundError is popping up. However, I don't understand why it would be a circular dependency. Everything works fine when I comment out the display app by the way. -
Different HTML template for Update View Django
I use this as class as an Update view: class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView): model = Post fields = ['title', 'content_don'] def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def test_func(self): post = self.get_object() if self.request.user == post.author: return True return False Urls.py: path('post/new/', PostCreateView.as_view(), name='post-create'), path('post/<int:pk>/update/', PostUpdateView.as_view(), name='post-update'), path('post/<int:pk>/delete/', PostDeleteView.as_view(), name='post-delete'), Problem is, I want for User to get different template depending on choice before Update. For example, in create view a User1 can define 3 issues and then, User2 can update that model and he would be allowed to edit and see only couple of possible fields. So on my page I would have: HTML <a class="btn btn-success btn-sm mt-1 mb-1" href="{% url 'post-update1' object.id %}">Update1</a> <a class="btn btn-danger btn-sm mt-1 mb-1" href="{% url 'post-update2' object.id %}">Update2</a> <a class="btn btn-warning btn-sm mt-1 mb-1" href="{% url 'post-delete' object.id %}">Delete</a> then when selected 'Update1' or 'Update2' User2 would see different buttons, options, fields. Should this be done with different UpdateView, different HTML template or? So, redirection to different Update form depending on choice for same 'POST' -
Object owner same as Foreignkey object constraint
How can one ensure that a foreignkey (Value.user) from one object (Value) corresponds to the foreignkey (Value.userobject) of another foreignkey object (UserObject.user): Value.userobject.user == Value.user class UserObject(Model): user = ForeignKey(User, on_delete=CASCADE) dummyvalue = DecimalField(max_digits=18, decimal_places=10) class Value(Model): user = ForeignKey(User, on_delete=CASCADE) # Ensure the object is owned by user, ie. userobject.user == user.. userobject = ForeignKey(UserObject, related_name='TheUsersObject', on_delete=CASCADE) dummyvalue = DecimalField(max_digits=18, decimal_places=10) class Meta: constraints = [ CheckConstraint( name="%(app_label)s_%(class)s_same_object_owner", check=( Q( ... ) ] Currently I can think of handling this when processing the request, but would much prefer handling this as a model constraint if possible.
