Problem with passing dynamic data to Chart.js in Django
i want to use data that i get from an API (numbers) and generate a bar chart with it. This is my views.py : import requests import os import json from django.http import JsonResponse, HttpResponse from django.shortcuts import render def btc(request): query_url = [ 'https://api.blockchair.com/bitcoin/stats', 'https://api.blockchair.com/ethereum/stats', 'https://api.blockchair.com/litecoin/stats' ] headers = { } result = list(requests.get(u, headers=headers) for u in query_url) json_data1 = result[0].json() json_data2 = result[1].json() json_data3 = result[2].json() labels = ["Bitcoin", "Ethereum", "Litecoin"] data = [json_data1['data']['transactions'], json_data2['data']['transactions'], json_data2['data']['transactions']] context = { "labels": labels, "data": data, } return render(request, "index.html", context) and this is in my index.html : <script src="https://cdn.jsdelivr.net/npm/chart.js@2.9.3/dist/Chart.min.js"></script><script> var config = { type: 'pie', data: { datasets: [{ data: {{ data|safe }}, backgroundColor: [ '#ff0000', '#0000ff', '#ff0080', '#73ffff', '#5c26ff', '#002db3', '#ffff26', '#4cff4c', '#ff00ff' ], label: 'Population' }], labels: ["Bitcoin", "Ethereum", "Litecoin"] }, options: { responsive: true } }; window.onload = function() { var ctx = document.getElementById('pie-chart').getContext('2d'); window.myPie = new Chart(ctx, config); }; </script> the problem is in {{ data|safe }} it works perfectly if i use Hardcoded data but when i try calling the data from the views.py i have an error. -
How to authenticate ngrok password automatically using Django and or Python?
I am using ngrok to expose my localhost on a raspberry pi, and ngrok is password protected. I am using Django on another computer outside my network to access a webpage(simple server) on this raspberry pi. I don't want to manually type in the username and password to ngrok. How can I automatically fill in the ngrok user/password? What I've tried: I first tried using JS in my template, just using a fetch request: https://user:password@myngrokdomain.ngrok.io but chrome threw an error in the console saying I can't pass in credentials in plain text like this, rightfully so... I then tried to use my Django view, and python requests: @login_required def cameraTest(request): UN= "myuser" PWD = "mypassword" loginURL = "https://myngrokdomain.ngrok.io" client = requests.session() client.get(loginURL) login_data = dict(username=UN, password=PWD,) header_data = dict(referer = loginURL) r = client.post(loginURL, data=login_data, headers = header_data) return TemplateResponse(request, 'cameraTest.html',) This didn't give an error, but it returned a 401 access denied from ngrok. Is there a simpler way to do this? I feel like javascript is probably the answer but I also can't seem to figure out a way to do it that doesn't involve passwords in plain text in the script. -

Django reverse foreign key values aggregate

Since it is a reverse foreign key I don't understand how can I achieve it. Please advise. -

Can I add a search box to a Django Admin Add page?
In a Django 3.0 app, I have a Donor Model with a foreign key to the donor's congressional district: # models.py class Donor(models.Model): """A class to represent an individual donor""" name = models.CharField( help_text = "Donor's name" ) district = models.ForeignKey( District, help_text = "Donor's congressional district" ) class District(models.Model): """A class to represent a U.S. congressional district""" dist_name = models.CharField( help_text = "District name" ) In the Admin Add page for Donor, there's a drop-down selection menu for District. The problem is that there are 435 congressional districts in the U.S. That's an awful lot to scroll through each time I add a Donor, so I'd like to add a search box. Django has the ability to define search fields. I tried to do so: # admin.py @admin.register(Donor) class DonorAdmin(admin.ModelAdmin): search_fields = ['district'] This did not affect the Donor Add page. 'District' still shows up as an enormous drop-down, and there are no search features anywhere on the page. The search_fields documentation says specifically Set search_fields to enable a search box on the admin change list page. Emphasis mine: search_fields seems to apply to only the Change List page, not the Add page. I assume this is why my … -
Django Unit Testing: AssertEqual Does not compare PermissionDenied with 403 and Terminates Prematuraly inside get_object()
I'm really hoping you may shed some light on a puzzling situation I am in with my unit testing of my post views. I am basically trying to test different post permissions depending on the user, ex: guest (anonymous), member (registered), and member who are mutually following each other (friends) When I run the unit test, it is erroring on the function that tests if a member (registered user) can view a post that is only meant to be visible to friends (mutually following each other): ====================================================================== ERROR: test_member_user_post_detail_friends_permission (journal.tests.test_views.TestPostDetailView) ---------------------------------------------------------------------- When I follow the line where the exception is taken place, it leads me to my get_object() of PostDetailView class where the testing seems to end prematurely (line marked below): def get_object(self, queryset=None): obj = super(PostDetailView, self).get_object(queryset=queryset) # Logged in user's friends ids (Users who they are following) my_friends = Follower.objects.filter(user_id=self.request.user.id).values( "follow_to" ) # Post owner's friends id (Users who the post owner is following) their_friends = Follower.objects.filter(user_id=obj.user.id).values("follow_to") if obj.permission == "friend": # viewable only by friends or staff/moderators if self.request.user.is_authenticated: if self.request.user.is_staff or self.request.user.is_moderator: return obj if self.request.user.id == obj.user.id: return obj # Check if they are following each other if self.request.user.id in [ i["follow_to"] for i in … -
Sizing Thumbnail using variable height and width in Cloudinary through Django
I have jpegs of paintings. The paintings have certain dimensions: Painting 1: 52cm x 40cm Painting 2: 30cm x 50cm The jpeg of these images may with various widths in pixels in similar dimensions and I have uploaded them into Cloudinary using CloudinaryField in Django. Jpeg of painting 1: 104px x 80px Jpeg of painting 2: 90px x 150px I want to display the thumbnails of these images by translating cm -> px, meaning I was to show the thumbnail in 52px x 40px.

How do I serialize specific field in Django ManyToMany field?
So, I'm trying to use Django Rest Framework for my project. I have two models Category and Content to be serialized, as below: views.py class Category(models.Model): category_name = models.CharField(max_length = 20) def __str__(self): return self.category class Content(models.Model): category = models.ManyToManyField(Category) body = models.TextField(blank=True, null=True) created_at = models.DateField(auto_now_add=True, null=True) def __str__(self): return self.created_at serializers.py class CategorySerializer(serializers.ModelSerializer): class Meta: model = Category fields = ['category_name'] class ContentSerializer(serializers.ModelSerializer): class Meta: model = Content fields = [ 'category', 'body', 'created_at', ] Now the problem is, the JSON object returned has the id of each object in Category, NOT the category_name. So when I console.log in my front-end, I get (for example) [1, 4, 8] but what I need is (for example) ['Wine', 'Beer', 'Whiskey']. How do I make that possible? Thanks in advance :) -
Django keeps using the wrong project settings file
Django keeps trying to use the settings file of a previously deleted project (project-x) when I run python3 manage.py runserver for any newly created project resulting in the error ModuleNotFoundError: No module named 'project-x' when the settings module is initiating.

When I manually set the settings module environment variable using export DJANGO_SETTINGS_MODULE=newproject.settings everything works however I would like to find the root problem and fix it.

DRF serializer data input format (json instead of request.data)
I created an api endpoint using DRF but the serializers have some really deep nested relationships and therefore cannot render out the serializer as form easily (for html). I therefore tried to create simple Django forms capture the user input and parse it into some complex nested jsons my own. However the serializers just cannot seem to accept normal json. Is it possible to make the serializer accept data in json format instead of "request.data"? If not what are the alternative ways of rendering forms in html? ( I thought of rendering out the serializer manually inside the template but I can't find any resources on how to do so) -

OpenCV Live Stream from Camera in Django webpage with image details

@permission_required doesn't check user group permissions
I am trying to check if a user has a permission to access a particular django view using @permission_required. The permission is assigned to the group x to which the user is assigned to. I confirmed with the database and through debugging that the user is member of the group and the group has the appropriate permission set. Nevertheless, @permission_required doesn't allow access to this user. The view has the following decorators: @login_required(login_url='ROUTE') @permission_required('PERMISSION', raise_exception=True) Is this an issue from django, or is there some workaround that needs to be done to consider group permissions? -
Creating automated docs for Django REST Framework
guys. I am to write documentation for Django (specially docs for APIs) project and want to use Sphinx. Unfortunately, Sphinx` docs and guides are out of date (Sphinx newest version is 3.5+). When I mean out of date guides and docs, I refer to this guides and others: https://www.freecodecamp.org/news/sphinx-for-django-documentation-2454e924b3bc/ (2018) https://www.sphinx-doc.org/en/master/usage/quickstart.html (official docs, it doesn't help) https://docs.djangoproject.com/en/dev/internals/contributing/writing-documentation/ https://columbia-it-django-jsonapi-training.readthedocs.io/en/latest/sphinx/ (Sphinx 1.8) The problem is that there are docs directory, that doesn't appear in new versions (in newest versions we`ve got sourse directory). I installed Sphinx to test project and run command sphinx-quickstart in app directory. My structure in test project after sphinx-quickstart: Test -- app ---- base ---- **build** ---- post ---- quickstart ---- templates ---- **sourse** ------ **_static** ------ **_templates** ------ **conf.py** ------ **index.rst** ---- **make.bat** ---- **Makefile** ---- manage.py ---- requirements.txt -- venv -- .gitignore -- Dockerfile -- docker-compose.yaml -- README.md Files between **** is what I`ve got after running sphinx-quickstart.

This is my views.py : import requests import os import numpy as np import pandas as pd from pandas import Series, DataFrame from pprint import pprint from django.views.generic import TemplateView import json from django.http import JsonResponse, HttpResponse from django.shortcuts import render def btc(request): query_url = [ 'https://api.blockchair.com/bitcoin/stats', 'https://api.blockchair.com/ethereum/stats', 'https://api.blockchair.com/litecoin/stats' ] headers = { } result = list(requests.get(u, headers=headers) for u in query_url) json_data1 = result[0].json() json_data2 = result[1].json() json_data3 = result[2].json() y = json_data1['data']['transactions'] context = { "bitcoin": y, "ethereum": json_data2, "litecoin": json_data3, } return render(request, "index.html", context) the problem is in the variable : 'y' in the index.html file : ethereum.data.transaction for example works perfectly so i want to do the same thing but directly into the views.py file (in python) because i need the variable to be a simple value not a json/dict value -
How to render formset manually?

Django, Dash App Safest Place to Keep Database Credentials
I'm new to web development. I have a Django project that loads a Dash app on one of it's pages. The dash app generates a chart that lets the user select certain datasets from the database. Directly inside my App.py (dash app) I placed my sqlalchemy database connection variables which one of the callbacks uses to fetch the data when requested. sqlEngine = sa.create_engine('mysql+pymysql://host:password@127.0.0.1:3306/db', pool_recycle=3600) dbConnection = sqlEngine.connect() conn = pymysql.connect(host='127.0.0.1',user='host',password='password',db='db') cursor = conn.cursor() app = DjangoDash(name='app', add_bootstrap_links=True, serve_locally = False) ... @app.callback(...) def fetch_data(...): select = """SELECT * FROM `db`.`table`;""" df = pd.read_sql(select, dbConnection) I'm not sure if this is a safe practice in a production environment. What would be the best/safest way to connect to the database inside of the dash app. My Django app is also connected to the database for migrations. Thanks for any help/advice.
