Celery unavailable after dockerization in a Django app
I have a Django app that I've been trying to dockerize. I've successfully dockerized Django with gunicorn and nginx so the main part of the app is running. However, I also have tasks that need to be run using Celery. I dockerized rabbitmq, and I think that was successful, as before installing it I had Connexion refused and I don't anymore. I only lack Celery to be dockerized so, as my tasks are not executed nor stored in the database, my Celery configuration is probably wrong, however I couldn't find where I'm going wrong with it. Here is my docker-compose.yml: version: '3.8' services: django_gunicorn: volumes: - static:/app/static - media:/media env_file: - env build: context: . ports: - "8000:8000" nginx: build: ./nginx volumes: - static:/static - media:/media ports: - "80:80" depends_on: - django_gunicorn rabbitmq3: image: rabbitmq:3-alpine ports: - 5672:5672 celery: restart: always build: context: . command: celery -A main worker -l info env_file: - env depends_on: - rabbitmq3 - django_gunicorn volumes: static: media: Dockerfile: FROM python:3.10.5-alpine RUN pip install --upgrade pip RUN wget https://upload.wikimedia.org/wikipedia/commons/b/b9/First-google-logo.gif -O media/media.gif COPY ./requirements.txt .

Django placing order (like restaurant etc)
I'm building an online restaurant website, I have an app with a few models containing the Menu. I want to add another app that utilizes the Menu models to populate multiple choice field. Something like an ordering page. But I've no idea how to do that. Also, how should my order model look like? -
I am trying to create an app that uses the Django REST Framework and Flask, but it is not working correctly
I'm having trouble with my python app using django and flask framework. It's creating a database and all of that stuff but when it tries to make a request to /api/v1/users, it always comes back with data errors. I've tried looking at the logs for the site and it says the same thing "connection refused" when the server makes a connection attempt, and I can't seem to figure out why this is happening. My code looks like this right now: from flask import Flask, jsonify, request import datetime app = Flask(__name__) db=sqlite3.connect('data.db') class User(object): def __init__(self, id, name, email, password): self.id = id self.name = name self.email = email self.password = md5_hash(password).hexdigest() def __repr__(self): return "<User %s>" % (self.id,) @app.route("/api/v1/users", methods=('GET', 'POST')) def users(): if request.method == 'GET': users = db.execute('SELECT * FROM user ORDER BY id ASC').fetchall() data = dict(users=users) return jsonify(data) elif request.method == 'POST': newuser = User(request.form.get('id'), request.form.get('name'), request.form.get('email'), request.form.get('password')) db.executemany("INSERT INTO user VALUES (?,?,?,?)", (newuser.id, newuser.name, newuser.email, newuser.password)) return jsonify(status="ok") else: return "Invalid method." @app.errorhandler(404) def page_not_found(e): return jsonify(status='Not Found') if __name__ == "__main__": app.run(host='0.0.0.0', port=5000) The error message I get in the logs is: 127.0.0.1 - - Referer: http://localhost:5000/api/v1/users 127.0.0.1 - - Connection: close 127.0.0.1 … -
Django User cannot login
I made a simple register and login script, the register script works and sends the user information to a database but the login does not log the user in.

How to enable URL MASKING changing HTTP HEADERS
I have a django application (version 4.0.3) and I want to URL MASK some specific URLs using new purchased domains (in this case GoDaddy) So what I want to do is: www.originaldomain.com/url1 beeing masked with www.newdomain.com. But when I redirect with mask in domain www.newdomain.com some HEAERS do not allow it (I know because GoDaddy tech support said me "something is blocking it"). If I do a normal redirect (301 or 302) it works, but not with URL Masking. I tryied removing X-Frame-Option: Deny using a django decorator to the view but still not able to make it work.

Setting value to default in a django for loop
I've been stuck on a rather simple issue, where i'm trying to either set a value on a variable in a for loop, or setting the default data to N/a. I set up a datatable that gathers lots of data, but i need to return 2 of the variables to N/a if not found in the for loop. In the code example below, you can see a generic example of what i've tried. In the 2 for loops i'm trying to set a global var, that i can than access outside of the for loop. I've done some reading and i just can't figure out the smartest way of doing this. Hence me asking the question here. Please do ask if you need additional information. {% for vlan, macs in info.vlans.items %} {% for mac in macs %} {% endfor %} {% endfor%} {% if vlan %} <td>{{vlan}}</td> {% else %} <td>N/a</td> {% endif %} {% if mac %} <td>{{mac}}</td> {% else %} <td>N/a</td> {% endif %} I did also try to set the values within the for loop, but it won't work for the ones that do not have a mac or vlan assigned, as it does not set … -

Django filter charfield by greater than X principle
Possible duplicate, but no answers so far got any close to the solution. Imagine you have a charfield like this: 1.1.1.1 arriving in the request. I.e. basic semantic version. You need to filter all the objects in the queryset, where their version charfield is greater than this. For example we have such records in the DB: 0.0.0.0 0.0.0.1 1.0.0.0 1.1.1.1 1.1.1.2 2.2.2.2 And in the example provided I gave the version number as 1.1.1.1. So filtering by "greater than this" principle we will get only [1.1.1.2, 2.2.2.2]. Right now I'm filtering just by using regex. But how to do this using django ORM? -
Simulate CSRF attack in Django Rest Framework
I'm trying to get an understanding of how CSRF tokens work, currently my goal is to create a situation where the CSRF attack is possible. I'm hosting two Django apps locally on different ports. I access one by localhost:8000, the other by 127.0.0.1:5000 -- that ensures cookies are not shared between apps. There's an API view class ModifyDB(APIView): def post(self,request,format=None): if request.user.is_authenticated: return Response({'db modified'}) else: return Response({'you need to be authenticated'}) which shouldn't be accessed by unauthenticated users. The "malicious" site has a button that's supposed to trigger the attack when a user is logged on the target site: const Modify = () => { const onClick = async e => { e.preventDefault(); const instance = axios.create({ withCredentials: true, baseURL: 'http://localhost:8000', headers: { 'Accept': 'application/json', 'Content-Type': 'application/json', } }) const res = await instance.post('/api/modifydb'); return res.data } return ( <button class = 'btn' onClick = {onClick}> send request </button> ) } My authentication settings are as follows: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'my_proj.settings.CsrfExemptSessionAuthentication', ], } where CsrfExemptSessionAuthentication is a custom class that disables csrf protection for my educational purposes: class CsrfExemptSessionAuthentication(SessionAuthentication): def enforce_csrf(self, request): return django.middleware.csrf.CsrfViewMiddleware is also disabled. Both CORS_ALLOW_ALL_ORIGINS and CORS_ALLOW_CREDENTIALS are set to true. My question … -

How to print an API reponse value in a table column without the values being overidden?
I am working on a website using django, django-filter ,django-crispy-forms, and datatables for easy pagination and filtering. I have been able to successfully implement the required view and datatable in order to pull data from the django database and print it in a table how I want it presented. The issue I am running in to, is that I need to fill one of the column items on each row of the table with a value that comes from an API call to a separate website to get the status of an individual player in current time. As you can see from the below snippet, my most recent attempt was using ajax to pull the require api data (Note: I have also tried using fetch, and some javascript). But no matter what I am trying I am unable to get and print the data as required. In the below using ajax, I run into an issue, where when the for loop runs (2 iterations), if I leave async as true it runs and fills out the first row of the column in question, but does not put data in any other row. When I check the console I can see … -
