Proper Angular-side (frontend-side) implementation of token-based Authentication check
About my problem I am a total beginner which implements a web app (frontend Angular6, backend django[MySQL]). I am aiming to deploy it to a production environment, so I concern about authentication and authorization issues. The purpose of this post is about how to properly implement a Token-based (simple or even better JWT Auth) or even another proposed Authentication system. What I have came across So, in each angular tutorial about token-based authentication that I have watched at youtube, there is being implemented an "authentication service", say authService, that stores either token (in case of constant token) or token along with refresh_token (in case of JWT-Auth) at localStorage whenever a user logs in to the app. Thus, if they (tutorials) want a component to be loaded only to logged-in users, they attach a "CanActivate Guard", say authGuard, to that component. The problem comes right here. The authGuard checks if there is a logged-in user by checking only the existence of the corresponding data (e.g. a key-value pair, where key="token") within localStorage variable. Also, there is not being any kind of verification (e.g. communication with the backend) for the value of that token and finally, this token will be attached to … -
How to route tasks to queues while using Docker
I’m setting up multiple workers which execute tasks based on given queues with in a docker environment. I'm unable to see queues that I have declared in settings.py I've seen that the worker command that is on the top(in container command) is only getting executed and the rest are not being executed. This is how I'm trying to route celery tasks in settings.py # Celery settings CELERY_BROKER_URL = 'redis://:secret@redis:6379/0' CELERY_RESULT_BACKEND = 'redis://:secret@redis:6379/0' CELERY_ACCEPT_CONTENT = ['application/json'] CELERY_RESULT_SERIALIZER = 'json' CELERY_TASK_SERIALIZER = 'json' CELERY_TIMEZONE = TIME_ZONE CELERY_TASK_ROUTES = { 'app1.tasks.*': {'queue': 'emails'}, 'app2.tasks.*': {'queue': 'parser'}, 'app3.tasks.task1': {'queue': 'sms'} } This is how Im writing my tasks.py file. @app.task(bind=True, queue='parser') def parser(self, extension, data, file): return True This is how Im giving commands in my docker-compose.yml file in a container version: '3.3' services: api: restart: always build: ./app volumes: - ./app:/app/ depends_on: - redis command: bash -c 'python3 manage.py makemigrations --noinput && python3 manage.py migrate --noinput && celery -A app worker -l info -Q email-n worker1 && celery -A app worker -l info -Q parser-n worker2 && celery -A app worker -l info -Q sms-n worker3 && celery -A app worker -l info && celery -A app beat -l info && python3 manage.py … -
In django, is it a bad practice to retrieve database records with slug fields loaded by fixtures?
I am working on a code base where the original developer created a 'ProductType' model with several rows in the database representing a few product types. Throughout the code, there are statements like ProductType.objects.get(slug='foo_product_type'). These statements will cause a hard crash if fixtures haven't loaded the ProductType record with slug = 'foo_product_type'. What is the best practice to define the ProductType with slug 'foo_product_type'? It seems like python code shouldn't depend on fixtures being loaded, but I really can't think of another solution. I have worked with using choices= on the model definition, but that seems to be more for data integrity as opposed to loading a record with details like price so that doesn't help me. I currently load fixtures after migrating a new database, and that works, but I'm curious if anyone has a better solution. if ProductType.objects.get(slug='foo_product_type'): when ProductType with slug 'foo_product_type' doesn't exist. When the fixture is loaded, the object is grabbed for use in code. When record is missing, app crashes. -

Is there a way for a Django Project running on an Apache Server bilaterally communicate with an external python script?
I have a Django project running on an Apache2 server for a web application that shows the status of certain external drives. I used to have some linux commands called in a python script that dealt with mounting/unmounting hard drives inside the project. However I had to move the commands to a new external python script as the computer didn't recognize the changes of mount/unmount of the drives since it was hidden inside the virtual environment. I now need this external python script to communicate to the Django project's python script to tell if a drive was mounted along with the Django project to tell the python script to unmount a certain drive. I tried creating a WebSocket to provide bidirectional communication as pipes are only a single direction. But I can't get the WebSocket to connect/run when it's called in the Django app. def Tcp_connect( HostIp, Port): global s s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect((HostIp, Port)) return def Tcp_Write(D): s.send(D + '\r') return def Tcp_Read( ): a = ' ' b = '' a = s.recv(1) while a != '\r': b = b + a a = s.recv(1) return b def Tcp_Close( ): s.close() return def start(self,request): Tcp_connect( '127.0.0.1', 17098) … -

Provided og:image URL, [url to AWS S3] could not be processed as an image because it has an invalid content type
Building my company website and want the image to display when I share the link on facebook. The correct meta description and titles show up for each page but not the images. The facebook debugger tool keeps giving me this error and everytime I share a link it says that it has an invalid content type. I want my logo to appear for everytime I share a link on facebook so I have it extended in my base.html file.

Django pages won't load after installing pgAdmin4
I just installed pgAdmin4 so I could inspect my database visually and forgot to change the port from 5432 to 7000 and now when I run the django server by doing python3 manage.py runserver 7000 it just keeps loading and never actually loads the page. When I try to run the server with 5432 or 8000 it says that both are in use. When I set up the server I used localhost on port 5432 I deleted the server in the pgAdmin page and it didn't help. If you need more context please tell me and I'll modify the question. -

Creating a custom Django widget that uses several input fields and JavaScript
What would be the best way to go about creating a functionality layer to turn a basic text widget from form.CharField into one with several fields and JavaScript functionality, yet would still map to the same CharField, when submitted. I can think of a way where the original text input widget would be hidden with JS and then the array of new fields would be created, but I am not sure how well that would scale when several of these fields would have to be instantiated. I'm hoping there would be a better, cleaner way to do this. -

How to prevent deletion of Django model from Django Admin, unless part of a cascade
I have a project using Django 2.2.4. I have a Django model called Company. I use a post_save signal to make sure that as soon as a new Company is created, a new model instance called "Billing" is created, which is associated with that Company. This contains the company's billing information. This works great. Since my Billing object is associated with a Company, and I use on_delete=models.CASCADE, as soon as the Company is deleted, the Billing object associated with that company is automatically deleted as well. This works great too. Since the Billing object for each company is now automatically created and deleted along with the Company, there's no need for admins using the Django Admin web interface to ever have to manually create, or delete Billing objects. I want to hide this functionality from them. Normally, the common way to prevent Django Admin from allowing someone to add or delete an object is by adding this to that model's ModelAdmin in admin.py: class BillingAdmin(admin.ModelAdmin): ... # Prevent deletion from admin portal def has_delete_permission(self, request, obj=None): return False # Prevent adding from admin portal def has_add_permission(self, request, obj=None): return False This works, and does indeed hide the ability for Admins … -

Resolving "No Space left on device"
I have my static and Django code on two different repositories on Gitlab. When I try combining the compiled static part of the code in the Django repository it throws an error as shown in the text below.

hhtp timeout even after making a server call ( ajax call ) every 3 mins (180 sec) to have server respond and keep the http connection alive
i am working on a django application currently deployed on azure app service.i includes generation of report in docx. format. in some scenerios i takes upto 5-6 minutes. at first i encountered activity timeout after 70 sec which i solved by using applicationHost.xdt to configure activitytimeout and request timeout. then another timeout happened after 230 sec almost. which according to my knowledge is due to load balancer. i understand it is not configurable in app service.. do i tried another technique which basically does is that it keeps pinging backend from client after every 180 sec. but the problem didn't go away. pasting detailed code below. Thanks in advance function pinger(stop) { if (status == true) { return; } else { $.ajax({ async : false, url:"{% url 'DummyUrl' %}", type: "GET", data: {}, beforeSend:function() { console.log('starting dummy') }, success:function(response){ console.log('success dummy') console.log(response.data) }, complete:function(){}, error:function (xhr, textStatus, thrownError){} }); return; } } function generate_report() { var status = false; $.ajax({ async : true, url:"{% url 'GenerateReport' %}", headers: { "X-CSRFToken": '{{csrf_token}}' }, type: "POST", data: {}, beforeSend:function() { console.log('starting'); console.log('readonly'); }, success:function(response){ if (response.data.toString().includes('.docx')) { console.log(response); var url_mask = "{% url 'download report' filename=12345 %}".replace(/12345/, response.data.toString()); console.log('document generated successfully here … -
Printing to console in Pycharm Django views.py
I am new to Pycharm (v2019.2) and Django (2.2.4). I am trying to understand pieces of code in various files and am trying to print data to the windows at the bottom of Pycharm, i.e. Run, manage.py, Terminal, Python Console. I've tried various solutions. I've added LOGGING to settings.py file according to the Django tutorial and importing logging. Nothing came out. I've also tried editing Run > Configurations in Pycharm but to no avail. #views.py from django.shortcuts import render, redirect from .models import Customer def index(request): if request.user.is_authenticated: groups = Customer.objections.select_related('group').values('name', 'address', 'group__name', 'group__limit') print(groups) for item in groups: print(item) context = {'group_list': {'data': list(groups)}} return render(request, 'index.html', context, request.user) else: return redirect('/accounts/login') My page loads fine but I just don't see any output to my consoles. -
