How to get the pk of a post in which a comment is contained?
In my code, I have an "add comment" option on my posts, but am struggling to make a cancel button for the create comment form as I keep getting a NoReverseMatch error. I'm trying to just have the cancel button be a link back to the post instead of anything too fancy, but it doesn't seem to recognize the URL I'm giving it. It's supposed to be a link to my posts, while calling the pk of the post that contained the comment. I've been trying to make some kind of workarounds, including a designated cancel function, trying to pull info from the URL, etc. but just can't see what I'm doing wrong. Even more puzzling is that the template related to CommentCreateView doesn't work, but the one related to CommentUpdateView does even though they're the exact same. I've included the relevant code below, and I'm new to django so please let me know if there's anything else that would be helpful to include. Thank you! error message: NoReverseMatch at /post/29/comment/ Reverse for 'post-detail' with arguments '('',)' not found. 1 pattern(s) tried: ['post/(?P<pk>[0-9]+)/$'] views.py: class CommentCreateView(LoginRequiredMixin, CreateView): model = Comment fields = ['text'] def form_valid(self, form): form.instance.author = self.request.user form.instance.post_id … -
Django Form Error: Make select field not required
I have a web app in which users can add items to a list and categorize those items. The users can also create those categories. The system works great when the user selects a category from the dropdown, though if the user hasn't made any categories, or wishes to not categorize an item, django throws an error under form.is_valid, stating: Select a valid choice. That choice is not one of the available choices. I have gone as far as to modify the choices on the form to be whatever the user submits but to no avail. I attempted to set the choice to a premade "None" category, but this still did not work. Here is my post method (when the user clicks the "create" button to make the item: def post(self, request, *args, **kwargs): form = ItemForm(request.POST) print("Post Request: " + str(request.POST)) choice = request.POST.get('category') print("Selected choice index: " + str(choice)) current_list = List.objects.get(id=request.session["list"]) category_choice = Category.objects.filter(list=current_list, id=choice) if not category_choice.exists(): no_category_list = List.objects.get(id=26) category_choice = Category.objects.filter(list=26, name="None") #Set the choice to whatever the user inputted form.fields['category'].choices = [(str(choice), category_choice)] print("Category Object: " + str(category_choice)) print("Form Choices: " + str(form.fields['category'].choices)) if form.is_valid(): item = form.save() json = { "item": item.to_json() … -

Uploading multiple images into django rest framework/react
Trying to do a fairly simple project where I can upload multiple images to my server with just a few other fields. I tried to follow this post but wasn't able to get anywhere on it. I know I am going to need to break my models into two with 'PostImage' having a ForeignKey that relates to Post. And I know I will need to modify the serializer in order to allow an array of image files. Any help would be greatly appreciated. models.py: from django.db import models class Post(models.Model): title = models.CharField(max_length = 100) content = models.TextField() image = models.ImageField(upload_to='post_images') def __str__(self): return self.title serializers.py: from rest_framework import serializers from .models import Post class PostSerializer(serializers.ModelSerializer): class Meta: model = Post fields = '__all__' views.py: from django.shortcuts import render # Create your views here. from .serializers import PostSerializer from .models import Post from rest_framework.views import APIView from rest_framework.parsers import MultiPartParser, FormParser from rest_framework.response import Response from rest_framework import status # Create your views here. class PostView(APIView): parser_classes = (MultiPartParser, FormParser) def get(self, request, *args, **kwargs): posts = Post.objects.all() serializer = PostSerializer(posts, many=True) return Response(serializer.data) def post(self, request, *args, **kwargs): posts_serializer = PostSerializer(data=request.data) if posts_serializer.is_valid(): posts_serializer.save() return Response(posts_serializer.data, status=status.HTTP_201_CREATED) else: print('error', … -
Left Join in Django ORM
Say I have models called "Post" and "Reaction" and I have made a Post, saved it and now I want to react on it with a Reaction. Now, when I visit my feed where a list of Posts is, I want to show my reaction if I had one. Which means: {% if post.my_reaction %}{{ post.my_reaction.contents }}{% endif %} Now, obviously I want to load more than just one Post; posts which don't have my reactions on it. I know that I used to solve this with SQL in PHP with SELECT * FROM Post LEFT JOIN Reaction ON Reaction.Post = Post.id AND Reaction.Author = <me> It's not quite clear how I could achieve this in Django -
Django dynamic url pattern based on model names: how to do it?
I was searching this for a while and did not figure out anyway. Let's say we have a models.py with 3 models dogs, cats and birds. In url.py we want to have a single line that works with generic ListView and DetailView for each model type. Our views.py is dynamic and accepts models from url.py. smth for eaxmple: from django.urls import path from django.views.generic import TemplateView from . import views from . import models urlpatterns = [ path('animals/<???>/', views.AnimalList.as_view(template_name = 'animals.html', model = ???), name='lots'), ] so when we go to .../animals/dogs, it loads data from dogs, or when we go to .../animals/cats we get data from cats table, and so on. How do we do this? p.s. I have the working views.py based on generic so I am not sharing it here :) -
Serialize many-to-many relation with intermediate model in Django Rest
I tried to check another topics, but didn't found a solution... I have a many-to-many model, that have intermediate model with another field additional_field inside. class BoardField(models.Model): title = models.CharField(max_length=500, default='') class Article(models.Model): title = models.CharField(max_length=500, default='') fields = models.ManyToManyField(BoardField, through='ArticleField', through_fields=('article', 'board_field')) class ArticleField(models.Model): article = models.ForeignKey(Article, on_delete=models.CASCADE, related_name='task') board_field = models.ForeignKey(BoardField, on_delete=models.CASCADE) additional_field = models.CharField(max_length=200, blank=True, null=True) I want serialize Article with structure: [ "title":"Title", "fields":[ { "board_field": { "title":"Title" }, "additional_field":"Additional info" } ] ] So, I wrote serializer: class BoardFieldSrl(serializers.Serializer): class Meta: model = BoardField fields = ( 'title', ) class ArticleFieldSrl(serializers.Serializer): board_field = BoardFieldSrl() class Meta: model = ArticleField fields = ( 'board_field', 'additional_field', ) class ArticleListSrl(serializers.ModelSerializer): fields = ArticleFieldSrl(many=True) class Meta: model = Article fields = ( 'title', 'fields', ) But I always got an error: Got AttributeError when attempting to get a value for field `board_field` on serializer `ArticleFieldSrl`.

Django DRF Getting Missing Auth Headers with JWT, but With Permission and Auth on ReadOnly Views
I'm working with both the latest Django 3.0.2 and DRF 3.11.0 using djangorestframework-simplejwt 4.4.0. I did not have this problem before on a previous Django 2.2.0 project (and older lib versions), but I cannot figure out why I cannot access a view with readonly permissions set and default authentication looks okay in settings. If I specify the authentication_classes as empty in the view, then it works fine, but this is just an example. I expected the defaults to work, from settings: unless I'm incorrect and should be explicitly set this way. I have also tried using gunicorn and waitress-serve, and it's the same result. Here is the view: class NoteList(generics.ListAPIView): """ List all Notes. Not used """ # authentication_classes = [] permission_classes = (permissions.AllowAny,) serializer_class = NoteSerializer def get_queryset(self): notes = Note.objects.all() return notes Here is my settings: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] REST_FRAMEWORK = { # When you enable API versioning, the request.version attribute will contain a string # that corresponds to the version requested in the incoming client request.

Django-bootstrap-modal-form don't return data if not using class-based view
I am trying to use modal forms for a photo gallery in my django site. The site uses django-bootstrap4 and django-bootstrap-modal-forms. Modal forms works fine for modifying photo comments or to remove photo from a gallery. But if I want to add photos to the gallery using a form with no related model the modal form returns no data when submitted after selecting one or several files and the modal form displays an error message : This field is required. If I use normal form to add photo (not modal), it works fine.

Trying to trace a circular import error in Django Python
I understand circular import error has been asked about a lot but after going through these questions I haven't been able to solve my issue. When I try to run my server in Django, it is giving me this error message: django.core.exceptions.ImproperlyConfigured: The included URLconf 'starsocial.urls' does not appear to have any patterns in it.

How to ensure for the delete check box to appear on Django inline formset
I am using Django inlineformset in a scenario where there are dependent (child) objects (purchase order and its item lines). For generating additional formsets at runtime I am using the utility from here. During change/update, I need an option where I can delete one or multiple line items from among the formset lines. The best way to do this (I have found so) is to have a manual over ride (in child form definition) where the auto_id is set to "False", and I have a "Delete" check box appear against each line item which I can mark "true" and on save, the marked lines are deleted. If the auto_id is set to "True", I find that the check box does not appear. (Actually, I can see that the check box appears momentarily but then disappears). I have tried to use the "Remove" option which appears on the item lines but find that even after save, the items are not physically removed from database. I am also marking "can_delete=True" in the formset definition. Where am I going wrong? How do I ensure that the "Delete" check box appears at all times. -

Convert comma to dot in Python or MySQL
I have a Python script which collects data and sends it to my MySQL table. I noticed that the "Cost" sometimes is 0,95 which results in 0 in my table since my table use "0.95" instead of "0,95". I assume the best solution is to convert the , to . in my Python script by using: variable.replace(",", ".") However, couldn't one solution be to change format in my MySQL table? So that I store numbers in this format: 1100 0,95 0,1 150000 My Django Model cost = models.DecimalField(max_digits=10, decimal_places=4, default=None) Any feedback on how to best solve this issue?

Django.admin - How to make a Modelfield disable if other field is == False
