How to display multiple views in a Django project's template?
I have a Django project with multiple apps and I would like to manage the template from the project root folder. TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', "DIRS": [os.path.join(BASE_DIR, "templates")], 'APP_DIRS': True, 'OPTIONS': {...} }] In the homepage index.html of the project I'm trying to display num_exchanges and num_accounts generated in the views.py of app1 and app2. The problem is that only num_exchanges is printed not the second variable. If I switch the include in urlpatterns then the second variable is generated not the first one. How can I print both variables ? urls.py (project) urlpatterns = [ path('admin/', admin.site.urls), url(r"^", include("app1.urls"), name='app1'), url(r"^", include("app2.urls"), name='app2'), ] index.html (project) {% load static %} {% block content %} <h2>App1</h2> <p>Records in database:</p> <ul> <li><strong>Exchanges:</strong> {{ num_exchanges }}</li> </ul> <h2>App2</h2> <p>Records in database:</p> <ul> <li><strong>Account:</strong> {{ num_accounts }}</li> </ul> {% endblock %} views.py (app1) from django.shortcuts import render from app1.models import Exchange def app1_stats(request): num_exchanges = Exchange.objects.count() context = { 'num_exchanges': num_exchanges } return render(request, 'index.html', context=context) urls.py (app1) from django.urls import path from app1.views import app1_stats urlpatterns = [ path('', app1_stats, name='index'), ] views.py (app2) from django.shortcuts import render from app2.models import Account def app2_stats(request): num_accounts = Account.objects.count() context = { … -

How to get POST and create message using DetailView on Django
I have Post model and Message model. I want to create message on one post and preview it message. I can't think of how I can do this using DetailView Class. How can I do this?

Debugging an elusive edge case where browser reloads randomly
I've spent weeks trying to figure out this bug. My app has a client where a specific page will reload after she's spent some time filling in new information in a form. I can't figure out any reason for the page to reload. There are no error messages. Nothing is being captured in Sentry. So I can't reproduce locally. How do I even start going about this... could I do some sort of context capture when listening to the page reloading event? As I'm not aware of any captured necessary information I'm not even sure what do send to sentry. I'll try and save the unsaved data to local storage. But... any ideas on how to go about this is much appreciated. -

Using Django all-auth in a standalone app: paths that do not start with 'accounts/' are NOT FOUND 404
I am using Django 3.2, and am creating a standalone user registration and management app, that uses django-allauth to handle all of the registration functionality. My stand alone app directory structure is like this: core /core settings.py urls.py # ... /django-myown-userprofile /userprofile models.py urls.py # ... myapp.tox setup.py setup.cfg # ... core/core/urls.py from django.urls import path, include urlpatterns = [ # ... path(user, include('userprofile.urls')), path(admin, admin.site.urls) ] core/django-myown-userprofile/userprofile/urls.py from django.urls import path, include urlpatterns = [ path('accounts', include('allauth.urls')), path('accounts/profile', ProfileView.as_view(), 'user-profile'), # ... ] When I attempt to access any of the allauth endpoints (e.g.): http://localhost:8000/user/accounts/login I get the error 404 Not found. It seems that django-allauth is expecting the path to be of the form: http://localhost:8000/accounts/... How do I change this behaviour of django-allauth ? -
How to integrate python script in a django project
So I am extremely new to programming, and am stuck at this issue, I am using python with Django and Mongodb for database. I need to write a service that assigns an ID (not the one assigned by mongodb) upon each user form submission. for example entry 1's ID will be [Prefix entered by user] 2101, entry 2's ID will be [Prefix entered by user] 2102, so its basically adding in the number 2100. I have no idea how and where to integrate this logic in my code. I have tried a few solutions on the internet but nothing seems to work. my code: Model.py class Writeups(Document): blog_id = 2100 title = fields.StringField(max_length=120) date_created = fields.DateField(blank=True, null=True) date_modified = fields.DateField(blank=True, null=True) version_number = fields.DecimalField(null= True , max_digits=1000, decimal_places=2) storage_path = fields.StringField(max_length=120) STRIKE_READY_BRIEF = 'SRB' STRIKE_READY_THREAT_REPORT = 'SRTR' PREFIX_CHOICES = [ (STRIKE_READY_BRIEF, 'SRB'), (STRIKE_READY_THREAT_REPORT, 'SRTR'), ] prefix = fields.StringField( max_length=4, choices=PREFIX_CHOICES, null=False, blank=False, ) views.py: @csrf_exempt def writeups_request(request): """ Writeup Request """ if request.method == 'GET': try: data = { 'form-TOTAL_FORMS': '1', 'form-INITIAL_FORMS': '0', } writeups = WriteupsFormset(data) # print(writeup) return render(request, "writeups/writeups.html", {'writeups_forms': writeups}) except Exception as e: print(e) response = {"error": "Error occurred"} return JsonResponse(response, safe=False) if request.method == … -

Django : Why is string condition False if select_related field not coated in STR()?
In my function, my query is : mappings = MappingField.objects.filter( fl_fiche_header_flow_id=fhf.pk).order_by('fl_fiche_inside_field_position') .select_related('fl_fiche_header_flow') Why when I print (label is models.Charfield): mapping.fl_fiche_header_flow.label I got well : appli1 And when I check the condition : if mapping.fl_fiche_header_flow.label == 'appli1': I obtain False? Why do I need to str(mapping.fl_fiche_header_flow.label) in my condition for getting true? Is it only due to select_related or is it a general principle ? -

Django REST Framework - Custom serializer overrides model constraints
My goal is to capitalize all letters coming in a specific field from the user payload in Django Rest Framework. Here the model: class Order(models.Model): class Item(models.TextChoices): FIRST= 'FIRST', _('FIRST') SECOND= 'SECOND', _('SECOND') ... order_id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True) the_item = models.CharField(max_length=8, choices=Item.choices) The only values admited are "FIRST" and "SECOND" in uppercase. I used this approach to capitalize the letters: In Django Rest Framework: from rest_framework import serializers class UpperCaseSerializerField(serializers.CharField): def __init__(self, *args, **kwargs): super(UpperCaseSerializerField, self).__init__(*args, **kwargs) def to_representation(self, value): value = super(UpperCaseSerializerField, self).to_representation(value) if value: return value.upper() and used in serializers.py like: class OrderCreateSerializer(serializers.ModelSerializer): #Force uppercase item = UpperCaseSerializerField() class Meta: model = Order fields = ['order_id', 'item' ] This actually works, because the input is converted in uppercase, BUT, the model constraints are not taken anymore into account. Payload Example 1: { "the_item": "first" } - LEGIT, converted in FIRST Payload Example 2: { "the_item": "FIRST" } - LEGIT, it's already uppercase Payload Example 3: { "the_item": "1234567" } - COMPLETELY WRONG INPUT, but it is accepted! It should be not! It's clear that it only cares about capitalizing and completely ignoring the model structure, which does not admit strings different from 'FIRST' and 'SECOND'. So, … -

Django returns 500 instead of 401 / 403 when no token passed
I have a Django view that requires a user to be authenticated (The app uses jwt), When the request is being passed without any Authorization header the response is 500, I want it to be 401 / 403 because it should not return an internal server error but an unauthorized error.

The problem is when I do .delete() function. it only removes the strings but not the row itself, making it only whitespaces. delete function def delete_comment(request): formType = request.POST.get('formType','') postID = request.POST.get('postID','') commentID = request.POST.get('commentID','') deleteComment = Comment.objects.get(id = commentID).cleanData() result = { 'code': 0, } return JsonResponse({'result':result}) EventListener in $('.delete-button').on('click', function(e){ e.preventDefault(); var commentID = $(this).attr('comment-id'); var form_type = $(this).attr('form-type'); var postID = $(this).attr('post-id'); $.ajax({ type: "POST", url: '/api/comment/edit_comment', data: { "formType":form_type, "postID":postID, "commentID":commentID, csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val() }, success: function(data) { $('.commentCard-'+ commentID).remove(); }, cache: false }); }); html <form action ="" form-type="deletebtn"> <button type="button" class="delete-button post-options btn text-nowrap" post-id = {{ post.id }} comment-id = {{Post_comment.id}} on-click="remove_comment({{post.id}}, {{Post_comment.id}})" > <i class='bx bx-message-square-x'></i> </button> </form> result when deleting result -
Filtering Base Django User by multiple groups
In my Django project I'm using base Django User and Group models. My goal is to get User queryset containing all User object who are assigned to multiple groups at the same time. For example I two groups and three users: from django.contrib.auth.models import User, Group a = Group.objects.create(name='a') b = Group.objects.create(name='b') user_a = User.objects.create_user('a', 'a@a.com', 'a') user_a.groups.add(a) user_b = User.objects.create_user('b', 'b@b.com', 'b') user_b.groups.add(b) user_ab = User.objects.create_user('ab', 'ab@ab.com', 'ab') user_ab.groups.add(a) user_ab.groups.add(b) I have tried filtering using __in on groups nad Q, but with no effect from django.db.models import Q User.objects.filter(groups__in=[a,b]).distinct() <QuerySet [<User: a>, <User: ab>, <User: b>]> User.objects.filter(Q(groups=a) & Q(groups=b)) <QuerySet []> My expected result would be: User.objects.filter(???) <QuerySet [<User: ab>]> -

Get value from many to many relation django
I would like to get value of the field 'name' of the model User but facing some issues. accounts = list(Account.objects.all()) To receive some value from foreign key models I use: accounts.currency.code (where Account my main model, Currency foreign key model and Code is required field) But for model with manytomany relation this way doesn't work. accounts.user.name 'ManyRelatedManager' object has no attribute 'name' But there name is a charfield of the model User. -
Prevent need for the same select_related clause on multiple views in DRF
Given the following models... class Player(models.Model): user = models.ForeignKey(User) class Activity(models.Model): player = models.ForeignKey(Player) and these serializers... class PlayerSerializer(serializers.ModelSerializer): class Meta: model = Player fields = ['user'] class ActivitySerializer(serializers.ModelSerializer): player = PlayerSerializer() class Meta: model = Activity fields = ['player'] if I want to use django-rest-framework to list all the activities, I need to do something like this... class ActivityViewSet(viewsets.ReadOnlyModelViewSet): queryset = Activity.objects.select_related("player__user") <--- this is needed because the activity serializer is going to serialize the player which has a user serializer_class = ActivitySerializer That's all fine. But then, every time I write a new view which, at some level, uses PlayerSerializer, I'm going to have to remember to do the proper select_related clause in order to keep the number of DB lookups low. I'm going to end up writing a lot of views which have the same select_related clauses (mine are actually a LOT more complicated than this example) and, if the PlayerSerializer ever changes, I'm going to need to remember to change all the view lookups. This doesn't seem very DRY to me and I feel like there must be a better way to do it. Have I missed something obvious?
