Django-tenants create user in a tenant only
I am currently setting up Django Tenants (https://django-tenants.readthedocs.io/en/latest/) with the Saleor Web Framework (https://github.com/mirumee/saleor-platform). I've managed to get the Saleor GraphQL endpoints up and running for two different sites. However, my users have to be created using the public schema or the login process does not work. For instance if run ./manage.py create_tenant --domain-domain=newtenant.net --schema_name=new_tenant --email=new@gmail.com this doesn't work. But running ./manage.py create_tenant --domain-domain=newtenant.net --schema_name=public --email=new@gmail.com works. The problem with creating in the public schema is that the created user will have access to all of the tenants. Extract from my settings.py SHARED_APPS = [ "django_tenants", "saleor.clients", # Django modules "django.contrib.contenttypes", "django.contrib.sites", "django.contrib.staticfiles", "django.contrib.auth", "django.contrib.postgres", "storages", # Local apps "saleor.plugins", "saleor.account", "saleor.discount", "saleor.giftcard", "saleor.product", "saleor.checkout", "saleor.core", "saleor.graphql", "saleor.menu", "saleor.order", "saleor.seo", "saleor.shipping", "saleor.search", "saleor.site", ] TENANT_APPS = ( # The following Django contrib apps must be in TENANT_APPS "django.contrib.contenttypes", "django.contrib.sites", "django.contrib.staticfiles", "django.contrib.auth", "django.contrib.postgres", "storages", # Django modules # Local apps "saleor.plugins", "saleor.account", "saleor.discount", "saleor.giftcard", "saleor.product", "saleor.checkout", "saleor.core", "saleor.graphql", "saleor.menu", "saleor.order", "saleor.seo", "saleor.shipping", "saleor.search", "saleor.site", "saleor.data_feeds", "saleor.page", "saleor.payment", "saleor.warehouse", "saleor.webhook", "saleor.wishlist", "saleor.app", # External apps "versatileimagefield", "django_measurement", "django_prices", "django_prices_openexchangerates", "django_prices_vatlayer", "graphene_django", "mptt", "django_countries", "django_filters", "phonenumber_field", ) INSTALLED_APPS = list(SHARED_APPS) + [app for app in TENANT_APPS if app not in SHARED_APPS] TENANT_MODEL = … -

Jquery/Ajax function does not work when clicking on icon for Django site
I have a script for an ajax request using jquery which acts to upvote a post on my django site. It works fine when I click on the part with the word "upvote", but when I click on my upvote icon, it doesn't register and shows 404 not found in console. I suspect this has something to do with document and not being able to act on icons. Could anyone help me identify the issue, or know a workaround?

Keeping field values on Form fields after request.GET - but also passing other kwargs
I have this form: class TaskSelectForm(forms.Form): def __init__(self, *args, **kwargs): # department = kwargs.pop('department') super(TaskSelectForm, self).__init__(*args, **kwargs) (...) I can call the form in my view with something like this: TaskSelectForm(request.GET) and it'll work fine. When i make a GET request the page loads and the fields are still filed.. Just as expected However, i need the form to take an extra parameter, something like this TaskSelectForm(request.GET, department = department) Problem is that for every GET request the form fields become empty. The form doesn't retain the values from the last request. I want the form fields to keep the last values.. How can i achieve this? I'll post the whole code below just to make sure i didn't mess up: class TaskSelectForm(forms.Form): def __init__(self, *args, **kwargs): department = kwargs.pop('department') super(TaskSelectForm, self).__init__(*args, **kwargs) department_tasks = Task.objects.filter(department = department) distinct_cr = [(k['client_repr'], k['client_repr']) for k in department_tasks.values('client_repr').distinct()] distinct_td = [(k['task_description'], k['task_description']) for k in department_tasks.values('task_description').distinct()] distinct_us = [(x.id, (str(x))) for x in department.users.all()] for _ in [distinct_cr, distinct_td, distinct_us]: _.sort(key = lambda x: x[0]) _.insert(0, ('', '---------')) self.fields['client_repr'] = forms.ChoiceField(choices = distinct_cr, required = False) self.fields['task_description'] = forms.ChoiceField(choices = distinct_td, required = False) self.fields['from'] = forms.DateField(widget = forms.DateInput()) self.fields['to'] = forms.DateField(widget … -

Django LeafletWidget custom style of geometry
I'm using django and leaflet for my app where I display gps tracks on a map. For my edit page of a gps track I use the LeafletWidget. Now I want to change the line style of this element. #forms.py class ActivityEditForm(forms.ModelForm): class Meta: model = Activity fields = ('name', 'track', 'desc') widgets = { 'track' : LeafletWidget() } And here a part of my html: //activity_edit.html <form method="post" enctype="multipart/form-data"> {% csrf_token %} {% bootstrap_form form %} <input type="hidden" name="next" value="{{ request.GET.next }}"> <button type="submit">Save</button> </form> Result: I'm a beginner in front-end and css. But I don't want the default blue line for the track. I want to change it to a red line with bigger width. In my normal map view I can change the style of the track on loading the tracks as geojson. But in the form it is already loaded and displayed and I don't know how to access the track to change its style. -

Password does not match for user "postgres" after deleting postgresql from local machine
I am running an application in 3 separated docker containers. One for postgresql, another one for Django and the third one for nginx. In my settings.py I retrieve data for my db settings from .env file like this: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': os.environ.get('DB_NAME'), 'USER': os.environ.get('POSTGRES_USER'), 'PASSWORD': os.environ.get('POSTGRES_PASSWORD'), 'HOST': os.environ.get('DB_HOST'), 'PORT': os.environ.get('DB_PORT'), } } I used sqlite for development but was building docker image using postgresql and it was working perfectly fine. Then for testing purposes I connected postgresql to django as development database with the exactly same settings. But after I returned to sqlite and built another image with this db settings it actually started returning password error. db_1 | Connection matched pg_hba.conf line 99: "host all all all md5" db_1 | 2020-09-20 16:39:02.730 UTC [36] FATAL: password authentication failed for user "postgres" db_1 | 2020-09-20 16:39:02.730 UTC [36] DETAIL: Password does not match for user "postgres".

Configuring Django with Nginx, uWSGI and Mysql on Docker
Нашел статью по настройке данного стека, но нашел в ней пару неточностей или я что-то упустил, пока понять не смог что не так. Докер начал изучать недавно, поэтому пока много чего непонятно. https://zotovp.wordpress.com/2019/07/07/djangouwsginginxpostgresql-in-dockerdocker-compose-for-development-and-production-deployment-%d1%80%d0%b0%d0%b7%d0%bc%d0%b5%d1%89%d0%b5%d0%bd%d0%b8%d0%b5-djangouwsginginxpostgresql-%d0%b2/ Основная проблема у меня возникла в файле docker-compose.yml. В статье в конце файла указан том и в нем сокет ports: - "8080:8080" volumes: sock: Если убрать эту настройку, то начинает ругаться на том сокета в настройках django и nginx. volumes: - ./code:/code - sock:/sock Я решил изменить и эти куски заменив таким образом: volumes: - ./code:/code - ./sock:/sock После этих изменений для режима "dev" все заработало. Но когда я попробовал переключить на режим "prod" проект django перестает запускаться. Переключение dev и prod осуществляется в файле docker-compose.yml согласно статье: #command: uwsgi --ini /etc/uwsgi.ini command: bash -c "python /code/projectname/manage.py collectstatic --noinput && python /code/projectname/manage.py migrate && python /code/projectname/manage.py runserver 0.0.0.0:8000" Основной вопрос у меня связан с настройкой сокета, а также причина почему при переключении в prod режим проект перестает работать.

Vue.js data not updating when receiving message from socket
I'm trying to design a vue.js app that updates data about the state of a game upon receiving a "new_state" message from a socket. The socket is implemented using django channels. This is what the code looks like: const ws_scheme = window.location.protocol == "https:" ? "wss" : "ws" const gameSocket = new WebSocket( ws_scheme + '://' + window.location.host + '/ws/play/' + game_id + '/' ) let vue = new Vue({ el: '#app', data: { current_turn: 0, last_turn: -1, current_card: 0, last_card: -1, number_of_stacked_cards: 0, last_amount_played: 0, won_by: -1, my_cards: [], other_players_data: {}, }, created() { gameSocket.onmessage = function(e) { data = JSON.parse(e.data) this.current_turn = data.state.current_turn this.last_turn = data.state.last_turn // ... update the other data }; }, }); When I receive the message, logging the data makes it apparent that I'm receiving correct information. However, if I go and type vue.current_turn after receiving the message, it's still 0 instead of the new value; same for all the other members of the data object. I tried with vue.current_turn = data.state.current_turn and it does work this way, but obviously it should work with this. What's wrong with my code? And generally speaking, what's the best way of accomplishing what I'm after, i.e. updating … -
Django file download as attachment on form submit doesn't work on mobile

Django form : how I can get a second user with instance?
I try to understand how I can fill automatically the seller user field: Assume I got private group with two users (one is consumer the other is seller) Only consumer can have access to this form.

Django redirecting URL view for the latest post
I am a novice to Django, so excuse me if this seems rather trivial. I am trying to create a link to the latest issue for an online magazine. Here is my code: home.html: {%extends 'base.html'%} {%load static%} {% block content%} <button href="#"> Latest Issue</button> {%endblock%} views.py: from django.shortcuts import render, get_object_or_404 from django.views.generic import ListView, DetailView, CreateView, UpdateView, DeleteView from .models import Post, Issue from .forms import PostForm, EditForm, IssueForm, IssueEditForm from django.urls import reverse_lazy from django.http import HttpResponse class HomeView(ListView): model = Issue template_name = "home.html" class IssueView(ListView): model = Issue template_name='issues.html' class IssueDetailView(DetailView): model = Issue template_name = 'issue_details.html' def get_context_data(self, **kwargs): context = super(IssueDetailView,self).get_context_data(**kwargs) context['posts'] = Post.objects.all() return context #This is to pass in my post model, so I can display the posts for each issue in issue-details.html. urls.py: from django.urls import path from .models import Post, Issue #from . import views from .views import HomeView, ArticleDetailView, AddPostView,EditPostView, DeletePostView,about_view, submit_view,IssueView, AddIssueView, IssueDetailView, EditIssueView urlpatterns = [ path('',HomeView.as_view(),name="home"), path('issue/',IssueView.as_view(), name="issue"), path('issue/<int:pk>', IssueDetailView.as_view(), name='issue-detail'), ] #Irrelevant urlpatterns omitted. I looked at this solution, but I was not able to implement it, especially since it is from 9 years ago. I did not know what view to put/create for … -
Django How can I pass a subquery in LEFT JOIN
I have 3 models (A,B,C): class A(models.Model): url = models.URLField() uuid = models.UUIDField() name = models.CharField(max_length=400) id = models.IntegerField() class B(models.Model): user = models.ForeignKey(C, to_field='user_id', on_delete=models.PROTECT,) uuid = models.ForeignKey(A, to_field='uuid', on_delete=models.PROTECT,) and I want to perform the following SQL query using the Django ORM: SELECT A.id, COUNT(A.id), COUNT(foo.user) FROM A LEFT JOIN (SELECT uuid, user FROM B where user = '<a_specific_user_id>') as foo ON A.uuid = foo.uuid_id WHERE name = '{}' GROUP by 1 HAVING COUNT(A.id)> 1 AND COUNT(A.id)>COUNT(foo.user) My problem is mainly with LEFT JOIN. I know I can form a LEFT JOIN by checking for the existence of null fields on table B: A.objects.filter(name='{}', b__isnull=True).values('id', 'name') but how can I LEFT JOIN on the specific sub-query I want? I tried using Subquery() but it seems to populate the final WHERE statement and not pass my custom sub-query in the LEFT JOIN. -
Face detection box does not appear on the local server. (Django)
It is a mask detection code (camera.py) using Yolo model. I tried to implement this on django server. The video appeared on the screen by webcam without any problems. However, the face detection box is not showing up. I tried using VideoStream instead of VideoCapture, but the results were the same. And when I printed out the jpeg, I checked that it came out properly. What's the problem?... import cv2,os,urllib.request import numpy as np from django.conf import settings # from imutils.video import VideoStream import imutils # load our serialized face detector model from disk os.chdir(r'C:/Users/rjsgh/OneDrive/Desktop/Mask_Detection/warming_up_project/streamapp') weightsPath = "./face_detector/yolov4-tiny-obj_best.weights" cfgPath = "./face_detector/yolov4-tiny-obj.cfg" yoloNet = cv2.dnn.readNet(weightsPath, cfgPath) layer_names = yoloNet.getLayerNames() output_layers = [layer_names[i[0] - 1] for i in yoloNet.getUnconnectedOutLayers()] LABELS = ["Mask", "No Mask"] COLORS = [(0,255,0), (0,0,255)] class yoloDetect(object): def __init__(self): self.vs = cv2.VideoCapture(0) def __del__(self): self.vs.release() cv2.destroyAllWindows() def detect_mask(self, frame): (h,w) = frame.shape[:2] blob = cv2.dnn.blobFromImage(frame, 1/255.0, (416, 416), swapRB=True, crop=False) yoloNet.setInput(blob) layerOutputs = yoloNet.forward(output_layers) class_ids = [] cofidences = [] boxes = [] for output in layerOutputs : for detection in output : scores = detection[5:] class_id = np.argmax(scores) confidence = scores[class_id] if confidence > 0.5 : box = detection[:4] * np.array([w,h,w,h]) (center_x, center_y, width, height) = box.astype("int") x … -
how can I download image with different sizes in jquery or python django?
I have an image which is displayed to user. User can select the size of image which he/she want to download. How can I do so. I don't want to store the different sizes of image. I want to create a function with parameter specifying the size which will be called when the user click the download button. From that function the image should get downloaded (without changing the actual file size and should not create a new file or if created should not get stored anywhere). If it is possible to do such thing in jquery will be appreciated, so that there will be no need to send request to backend, if not then in python django. -
How do I send a post with Django superuser authorization with the post method of HttpClient in Angular?
Can someone tell me how to login to my Django superuser making a post?
