How to fix in django "Page not found (404)" error ("Django tried these URL patterns... The empty path didn't match any of these.")
As a newbie to Django, I encountered the same problem as many before me. I would appreciate if you didn't mark my question as a double immediately because I checked the fixes those old posts suggested but to no avail, unfofrtunately. When I start server I get: Page not found (404). Using the URLconf defined in shops_online.urls, Django tried these URL patterns, in this order: admin/ api/organizations/ [name='organizations-list'] api/organizations/<int:id>/shops_file/ [name='get-shops-file'] api/shops/<int:id>/ [name='shop-view'] api/v1/token/ [name='token_obtain_pair'] api/v1/token/refresh/ [name='token_refresh'] api/v1/token/verify/ [name='token_verify'] docs/ [name='schema-swagger-ui'] The empty path didn’t match any of these. Here`s my views.py: from django.shortcuts import render from rest_framework.views import APIView from .models import Shop, Organization from shop.serializers import OrganizationSerializer, ShopSerializer from rest_framework.response import Response from rest_framework import status import pandas as pd import logging from django.http import HttpResponse from django.core.mail import send_mail from background_task import background from background_task.models import Task from background_task.models import Task from .tasks import send_email_task from rest_framework.decorators import api_view, permission_classes from rest_framework.permissions import IsAuthenticated from rest_framework.response import Response @api_view(['GET']) @permission_classes([IsAuthenticated]) class OrganizationListView(APIView): def get (self, request): try: organizations = Organization.objects.filter(is_deleted=False) serializer = OrganizationSerializer(organizations, many=True) # logging logging.info('GET request was successful') return Response(serializer.data, status=status.HTTP_200_OK) except Exception as e: logging.error(f'An error occurred while executing the request: {e}') return Response(status=status.HTTP_500_INTERNAL_SERVER_ERROR) @api_view(['PUT']) … -

get_form_kwargs being omitted

Add extra field to serializer
I need to add an extra field to serializer. I have below django serialzer { "count": 2, "next": null, "previous": null, "results": [ { "id": 8363, "name": "test10", "description": "" }, { "id": 8360, "name": "check", "description": "edew" } ] } I need to add a field, for example, let us call it as new_field. How can we make this possible? The structure I am expecting is below. { "count": 2, "next": null, "previous": null, "results": [ { "id": 8363, "name": "test10", "description": "" }, { "id": 8360, "name": "check", "description": "edew" } ], "new_field": "New Field Value" } -
GeoDjango: Building route of MultiLineStrings between 2 railway stations
I'm using GeoDjango (django.contrib.gis). I have 2 models: class RailwayStation(models.Model): point = models.PointField('Point') class RailwayLine(models.Model): mls = models.MultiLineStringField('MultiLineString') In my DB I have railway stations and a lot of railway lines (note: in most cases those lines do not directly connect stations between each other, they can be very short up to 50 meters). My goal is to be able to find the train's route between 2 RailwayStations (in other words the shortest route) that must consist of chained RailwayLines from my database, that would represent train's route, basically MultiLineString of concatenated MultiLineStrings from my database. ChatGPT suggested "networkx" package, not really sure if it is the suitable approach, as I have geo-data. Attaching 2 examples of RailwayLine's model MultiLineString - as I said they can be very short, as well as that long so one can be directly connecting 2 stations (very rarely). -

Python django error occurs when trying to use daphne for realtime channels server and corsheaders middleware together
Im am trying to make an application supporting both http and websockets i used djangorestframework for making http api and also i used channels to incorporate websockets and, with this setup when i try to serve the http server with the development server i dont get any error or application break but when I use daphne to try and serve both http and websockets server the application breaks with an error that await expression cannot be used in httpresponse,and note that after debugging I came to realise this only occurs because of the corsheaders middleware removing the middleware handles the error but i still need the corsheaders for my react frontend to work with django without any errors -
Using Django, updating a model using REGEXP_REPLACE with multiple patterns to match
I've searched and found similar posts but not this specific. I am currently trying to update a models JSON field using REGEXP_REPLACE. I want to do it in one query so I want to match multiple patterns and replace them in one call. With my current setup, if I have just one pattern I want to match the code works fine eg. name1, but as soon as I try to match multiple using (name1|name2) it doesn't work. A small example: We have a JSON field information on a model Person. The information field is populated with the following: {"name": "first_name last_name", "description": "Test description", "address": "123 example street"} The code I currently am using to do REGEXP_REPLACE is: find_pattern = r'(name|description)": "(.*?)",' repl_pattern = r'\1": "filler",' Cast( Case( When( **{f'information__isnull': False}, then=Func( Cast(information, output_field=CharField()), Value(find_pattern), Value(repl_pattern), Value('g'), function='REGEXP_REPLACE', output_field=CharField(), ), ), default=None, ), output_field=JSONField(), ) However this does not work and I can't figure out why. I get the following error: django.db.utils.DataError: invalid input syntax for type json DETAIL: The input string ended unexpectedly. Any help/ideas would be greatly appreciated, thanks. -

How can I serialize multiple unrelated tables to get combined JSON output via django rest framework?
I am working on an order management. Here's the scenario: User can create multiple types of orders and these order types are unrelated, but user can view all types of order. I have created an individual table for each of order type in models.py class OrderType1(models.Model): create_time = models.DateTimeField(auto_now_add=True, verbose_name="create_time") ordertype1_info = models.CharField(max_length=32, verbose_name="Exclusive info for OrderType1") class OrderType2(models.Model): create_time = models.DateTimeField(auto_now_add=True, verbose_name="create_time") ordertype2_info = models.CharField(max_length=32, verbose_name="Exclusive info for OrderType2") class OrderType3(models.Model): create_time = models.DateTimeField(auto_now_add=True, verbose_name="create_time") ordertype3_info = models.CharField(max_length=32, verbose_name="Exclusive info for OrderType3") In serializers.py, I have created serializers accordingly class OrderType1Serializer(serializers.ModelSerializer): class Meta: model = OrderType1 fields="__all__" class OrderType2Serializer(serializers.ModelSerializer): class Meta: model = OrderType2 fields="__all__" class OrderType3Serializer(serializers.ModelSerializer): class Meta: model = OrderType3 fields="__all__" Then here's the key problem: I want to create a serializer of order to return all orders of mutilple types like class OrderSerializer(serializers.ModelSerializer): class Meta: model = [OrderType1, OrderType2, OrderType3] fields = "common info of all types of order" If the serializer accepts GET request, I want to return JSON output like this: { "OrderType1":[ { "id": 1, "create_time": "2018-01-01 12:00:00", "ordertype1_info": "Exclusive info for OrderType1" }, { "id": 2, "create_time": "2019-12-01 12:00:00", "ordertype1_info": "Exclusive info for OrderType1" } ], "OrderType2":[ { "id": 1, "create_time": "2020-01-01 … -

¿It is possible to create a dynamic field in django admin?
The thing is I am creating a project on Django where my apps will work just on Django Admin View (so I dont want to create views or html templates). I am going to create two App: App One consist on showing just several models for example a Model named Client with client_id, name, country, etc. I can add data to my models, edit, delete, well the typical things you can do on Django Admin. Then App Two will be a model call Issue. On this model I want to register in database issues related to clients on a country. So, just with Django Admin I want to click on my model Issue then select a country and when I select the field country (that field will have a Foreign Key Obviously) on another field called country I want several checkbox for all the clientes of that country. The idea is to select with checkbox the clientes of that country that has reported an issue using just Models, Admin and maybe a Forms.py Thanks in advance I tried to overwrite admin.py with a personalized forms.py on this way: from django import forms from Dashboard.models import Country, Client class Issue (forms.ModelForm): … -
Celery Task Not Respecting Soft Time Limit in Django
In my Django project, I've encountered an issue with a Celery task that seems to ignore the soft time limit I've set for it. Here's the task definition: @shared_task(bind=True, soft_time_limit=18000) def my_task(self, args): # Actual task code here The problem is that this task continues processing for a much longer time, specifically 6 hours, even though I've set the soft_time_limit to 18000 seconds (5 hours). Why is this happening, and how can I ensure that the soft time limit is respected by the task? I appreciate any insights or suggestions on resolving this issue. Thank you! -

Ajax redirect broken when not uploading a file
I have a small bug where it would always redirect to a URL when I'm not uploading a file but when I upload a file it works perfectly and JS successfully captures the data for the user from Django. I tried changing up the function and redirects but unfortunately it's probably not that simple... Anyhow, here's the code I have written so far: type: 'POST', headers: { "X-CSRFToken": token }, url: window.location.href, data: examData, processData: false, contentType: false, success: function (data) { if (data.user_groups.includes('rasp') || data.user_groups.includes('canyon')) { window.location.href = "{% url 'red' %}"; } else { window.location.href = "{% url 'blue' %}"; } } The code above checks in the success Ajax function based on the given data to redirect to either red/ or blue/ depending on whether the user has those groups. As mentioned it works perfectly when the user hasn't uploaded a file. views.py for f in request.FILES.getlist('file'): handle_uploaded_file(request, f, task=db_item) messages.add_message(request, messages.SUCCESS, 'Success! Area added.') if request.user.groups.filter(name=rasp).exists() or request.user.groups.filter(name=canyon).exists(): user_groups = list(request.user.groups.values_list('name', flat=True)) data = {'user_groups': user_groups} return JsonResponse(data) else: if request.user.groups.filter(name=rasp).exists() or request.user.groups.filter(name=canyon.exists(): user_groups = list(request.user.groups.values_list('name', flat=True)) data = {'user_groups': user_groups} return HttpResponseRedirect(reverse('report')) This is the django function in views.py when a submit is clicked on … -

But when I try to do this by JS using fetch I got 500 internal server error There is my model: class User(AbstractUser): email = models.EmailField(unique=True) friends = models.ManyToManyField('self', symmetrical=True, blank=True) isPrivate = models.BooleanField(default=False) askBeforeStick = models.BooleanField(default=False) stickersOnBoard = models.ManyToManyField('Sticker', blank=True) first_name = models.CharField(("first name"), max_length=150, blank=False) last_name = models.CharField(("last name"), max_length=150, blank=False) def __str__(self): return 'Email: ' + self.email There is serializer: class UserSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = User fields = ['id', 'first_name', 'last_name', 'email', 'friends','isPrivate', 'askBeforeStick', 'stickersOnBoard'] There is url: router = routers.DefaultRouter() router.register(r'users', UserViewSet) router.register(r'stickers', StickerViewSet) urlpatterns = [ path('api/', include(router.urls)), view: class UserViewSet(viewsets.ModelViewSet): queryset = User.objects.all() serializer_class = UserSerializer and js: function getCookie(name) { let cookieValue = null if (document.cookie && document.cookie !== ''){ let cookies = document.cookie.split(';') for(let i = 0; i< cookies.length; i++) { let cookie = cookies[i].trim() if(cookie.substring(0,name.length + 1)=== (name+'=')){ cookieValue=decodeURIComponent(cookie.substring(name.length+1)) break } } } return cookieValue } let csrfToken = getCookie('csrftoken'); let friendButton = document.querySelector('#friendButton') friendButton.addEventListener('click',()=>{ let friendID = document.querySelector('#friendID') friendID = friendID.innerHTML let friendUrl = `http://localhost:8000/api/users/${friendID}/` let userId = "{{user.id}}"; let url = `http://localhost:8000/api/users/${userId}` fetch(url) .then((resp)=>resp.json()) .then(function(data){ let list … -
User-invisible tags in "django-taggit"
I use to create tags - "django-taggit". But there are several tags (20-30 pieces) that have a service value and should not appear in the template. Is there an easy way to make them invisible to the user without messing with the database? There are two opinions on this matter: Add the "turn on-off" column to the database. Try to somehow delete the desired tags by their "id". Is there a ready-made solution? -
adding a button in django admin programmatically
I have a model called "Process" and I want to rename its button in the admin_changelist view. I want to limit the overwriting of templates where possible. I created a custom form called SingleForm and a form called MultipleForm and I want a button that leads to each form. So I tried the following: Template first: {% extends 'admin/change_list.html' %} {% block object-tools-items %} <li> <a href="/admin/app/process/add_set/" class="addlink"> Add multiple Processes </a> </li> {{ block.super }} {% endblock %} ModelAdmin: class ProcessAdmin(admin.ModelAdmin): ... def get_urls(self): urls = super().get_urls() my_urls = [path("add_set/", self.add_process_set),] return my_urls + urls def add_process_set(self, request): return MultipleForm But I only end up with Process with ID “add_set” doesn’t exist. Perhaps it was deleted? Bonus question: How can I ONLY show the the button for add_set and omit the normal add button (I'd prefer without overwriting the template)? -
Django Imagefield - display current value in ModelForm
My model contains a ImageField called cover_image. cover_image = models.ImageField(upload_to=user_directory_path, blank=True, null=True) I have a working model form that allows users to upload book details including the cover_image from the front end. They also have the option to edit the book via the front end. In the model form the field is declared in the Meta with a FileInput widget and Bootstrap CSS class. 'cover_image': forms.FileInput(attrs={'class': "form-control"}), When edit is clicked, the form loads all the instance data except the cover image. The form can be updated and saved at this point without error. How can I access the current image path? The following both return nothing {{ form.cover_image.url }} {{ form.cover_image.path }} What's the appropriate way to deal with this? Am I expected to pass an instance of the object to the form?
