Docker + django + gunicorn connect to Nginx of the host system
On ubuntu server 18.04 I run a docker container with Django 3.1 and Gunicorn which connects to a locally installed Postgres. I already have an another Django project with Nginx and Gunicorn on the same server without docker. The questions are: how to set up socket files for Gunicorn in a container and connect this container to the existing external Nginx so I can access the containerized django app from outside? docker-compose.prod.yml version: '3' services: app: build: context: . ports: - "8001:8001" volumes: - ./app:/app env_file: - .env.prod command: > sh -c "gunicorn app.wsgi:application --bind 0.0.0.0:8001" I run the container like this: docker-compose -f docker-compose.prod.yml up .env.prod ... DJANGO_ALLOWED_HOSTS='111.111.111.111 .mysitename.com localhost 172.18.0.1 127.0.0.1 [::1]' ... when running container executing of this command: curl 'http://127.0.0.1:8001/admin/login/?next=/admin/' gives me the html code of the admin page and it's ok. The existing Nginx is set up as in these digital ocean tutorials: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04 I also secured it with Let's encrypt using this tutorial https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-18-04 -
Bring current user in logs inside Django
My goal in Django is to log every row with the current user so that when multiple users are using the app, I know which log is from whom. Step 1: I found that I can create filters for Logger: (like this) The problem that I have is that the record doesn't have a request inside. Step 2: I learn here, that I need middleware to store my current user so that logger could use it. My problem now is, that if I store in local, and then retrieve from local, apparently, this is not "same" local, so it doesn't have this information Middleware.py import threading local = threading.local() class UserNameMiddleware: def __init__(self, get_response): self.get_response = get_response # One-time configuration and initialization. def __call__(self, request): # Code to be executed for each request before # the view (and later middleware) are called. setattr(local, 'my_user', 'Marko') print('set local Marko') response = self.get_response(request) # Code to be executed for each request/response after # the view is called. return response Filter.py import logging import threading local = threading.local() class UserFilter(logging.Filter): def filter(self, record): print('INSIDE') record.myusera = getattr(local, 'my_user', 'None') print(record.__dict__) return True Step 3: So, I was thinking to create a variable inside … -
custom primary email to login and secondary to disable to login in django
I am trying to make email management. Users can add a secondary email and make it primary for login and disable the previous email to login in to django. I build some models, forms, and views.

Django Settings.py stuck on "SECURE_SSL_REDIRECT = True"
I added the setting SECURE_SSL_REDIRECT = True to my django settings.py. It works perfectly in production mode so no issues there however, now if I make it the following to test in development mode SECURE_SSL_REDIRECT = False I get the following error You're accessing the development server over HTTPS, but it only supports HTTP. What could the issue be? Seems like something is making it not register the new value. -
EmailMultiAlternatives not sending BCC emails

How to solve page not found 404 - python django?

Best way to take a Python program that runs on a terminal and get it running on Django
I have a chess game in python that runs on a basic terminal (user vs ai) and I essentially am trying to figure out the best way to take this terminal program and have it run in a Django project. I chose Django because it was recommended to me as a python based web framework and am also using Docker which should make it easier to get get hosted on a cloud service. I looked into some basic Django tutorials but they were also pretty basic about creating views and back end work. I thought it would just be simple to just run the python code, print to the screen, and take input but it seems more difficult than that. Essentially I would just like my program to run when a user loads the page but it seems more complex than that I am stuck trying to just recreate the terminal in Django. -
TypeError Object of type 'bytes' is not JSON serializable

Django model field dynamic choices which calls API
Say I have the following model: class DenyList(models.Model): vm_id = models.CharField(max_length=25) I want to add choices to the vm_id field, however the choices are dynamic via API of an external virtual machine registry system. so I have that done in the following way: class MachineChoices(object): def get_vms(self): if 'makemigrations' in sys.argv or 'migrate' in sys.argv: return [] # calls api, optionally cache, return the vms def __iter__(self): yield from self.get_vms() class DenyList(models.Model): vm_id = models.CharField(max_length=25, choices=MachineChoices()) The above works that: When creating migrations it won't call the API to set all the options in the migration file It is driven from the backend so it works on all model forms so as in django admin. Django admin displays the label instead of the raw value in list display (requires caching implemented in MachineChoices for efficiency) I don't feel this is elegant as it involves hackery to deceive django especially during migrations. I am aware that an alternative is to use autocomplete libraries but I need to customize with django forms. So are there any better ways to do this? -

Can't figure out how to Parse data from another endpoint using rest_framework
I'm trying to figure out how to parse data directly into a database in Django, i've gone through the rest_framework tutorial. But all can gather from that is, How to create an APIview which displays the data directly from the endpoint, since when i view the DB i can't see the data being stored after i have put the request through. Or i can create some kind of form to post the data through the front-end to the database, but that doesn't make any sense to do that since it would just be dataentry rather then just pulling the related keys. But i can't for the life of me figure out how to just request the data, parse it using an already existing model with the related keys and add that to a database. Feel free to destroy me for this but i really can't find anything in relation to this or maybe i just don't know the right lingo to search. -
Best way to set unique_together for all fields of a django model
I would like to prevent the creation of duplicated rows on some tables of my database. I know one way to do it is setting the unique_together or constraints attribute in the Meta class of the model as a tuple with the names of the fields, but I'd like to know if there's a better way to do it since my models have 30+ fields, so I don't think it would be practical to repeat the names of them again. The way I have it now: class MyModel(models.Model): model_id = models.BigAutoField(db_column="MyModelColumnID", primary_key=True) field1 = models.BooleanField(...) field2 = models.CharField(...) field3 = models. ... . . . field34 = models. ... class Meta: db_table = "MyTableName" unique_together = ( "field1", "field2", "field3", . . . "field34" ) I'm looking for something like unique_together="__all__" or all_unique=True, is this possible on Django? It is important to me to handle this as a database constraint, the get_or_create method won't suffice since it's for an app using multiple threads and making multiple concurrent calls to the database. Thanks ! -

how to add element in django list
I'm confused with how django adds elements to a list. consider the following: def add(request): if request.method == "POST": form = NewTaskForm(request.POST) if form.is_valid(): task = form.cleaned_data["task"] request.session['tasks'].append(task) # request.session['tasks'] += [task] return HttpResponseRedirect(reverse("tasks:index")) else: return render(request, "tasks/add.html",{ "form": form }) return render(request, "tasks/add.html",{ "form": NewTaskForm() }) if we add a print statement after request.session['tasks'].append(task) we get a list: ['check email'] we also get the same list if we comment the append line and use the correct way with += However, on the redirect to task/index the first way shows an empty list and the second way shows the list that's expected.
