NGINX Docker on Server with pre-existing NGINX
I am currently running into an issue with one of my projects that will be running in Docker on my Ubuntu Server with a NGINX docker container to manage the reverse proxy for the Django Project. My issue I am running into is I already have previous Django projects running on that particular Ubuntu server so port 80 is already being used by a NGINX block running on the actual server. Is there a workaround to running my Docker NGINX as well as the Ubuntu NGINX and have my docker image run as a "add on" site because the Django sites hosted there are clients websites, so I would prefer to not interfere with them if I dont have to. My project needs HTTPS because it is serving data to a React-Native app running on Android APK 28 which for some reason has a security rule that blocks non HTTPS connections from happening in the app. If anyone else has run into an issue like this I would gladly appreciate the advice on how to tackle this issue. I have tried running NGINX in Docker with port 81 instead of port 80 and that works perfectly, but I dont think … -

are there any clever ways to save files with Web socket in Django?
I have built chatting site and I'm thinking that I can add the function of sending files besides message. But it seems that web socket can't send files or images. My solution is that when file is sent, I use api and then fetched messages and files are reordered by timestamp. But if there are better ways to achieve this, I really want to know. So, my question is Is it possible to send files by web socket and get them by WebsocketConsumer? Is there any ways to combine those two processes? (ex. you send provisional link of files and store them as FileField? ) model from django.db import models from django.contrib.auth import get_user_model User = get_user_model() class Contact(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='contact_user') friends = models.ManyToManyField('self', blank=True, related_name='friends') def __str__(self): return self.user.name class Message(models.Model): contact = models.ForeignKey(Contact, related_name='message', on_delete=models.CASCADE) content = models.TextField() timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return self.contact.user.name class File(models.Model): contact = models.ForeignKey(Contact, related_name='file', on_delete=models.CASCADE) file = models.FileField() timestamp = models.DateTimeField(auto_now_add=True) class Chat(models.Model): participants = models.ManyToManyField(Contact, related_name='chats') messages = models.ManyToManyField(Message, blank=True) files = models.ManyToManyField(File, blank=True, null=True) timestamp = models.DateTimeField(auto_now_add=True) def last_30_messages(self): return self.messages.order_by('-timestamp').all()[:30] def __str__(self): return "{}".format(self.pk) I don't know what information is needed to figure this out, … -
Django migrations for docker container
I have been trying to resolve an issue i am having currently, but i have not found any adequate solution neither here or elsewhere, so i was hoping someone here might have an answer. I have gotten to a point where i know what the problem is but not how to resolve it. Basically i have a website running django/postgres/nginx, it runs smoothly and i can make new models and migrate them, but if i try to add a field to the model: from django.db import models class project(models.Model): project_name = models.CharField(max_length=50) author = models.CharField(max_length=30, blank=True, null=True) date_created = models.DateField() #Added in second round of migrations #Description = models.CharField(max_length=150,blank=True, null=True) What i would normally do is initially build and spin up my container sudo docker-compose -f docker-compose.yml up --build And within my entrypoint file i run makemigrations and migrate. The first round it works well, but if i add the Description field to my model, spin down and rebuild the container to allow the new field to be included in my container, the new container is build without the initial migration, and isntead with a new migration. This results in any previous postgres tables not getting the new field added … -
How to add a field to an existing model
I would like to extend and override the fields existing in the User model, which is found in "django.contrib.auth.models" (The model is already created). I first attempted to create a Foreign-Key and a One-to-One relationship between the User model, and a Client model (in which I added the extra fields), but I don't think it is good practice. How could I directly add and override fields within the User model and not have to create another class model to extend it. from django.contrib.auth.models import User class Clients(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) #client = models.OneToOneField(User, on_delete=models.CASCADE) cell = models.PositiveIntegerField (blank=False) address = models.CharField(default = "Sandton, JHB", blank = False, max_length=132) -

Django registration profile

Is there a way to check client in Django server without user authentication?
So I'm trying to build a Django application which provides each user with some contents but only limited to three times each day. For sake of convenience, I'm not thinking of creating/using any pre-existing user model or authentication. But since I have to limit the number of contents shown to each user, I have to tell if the current request is from the same person or not. I can think of enabling this in the front-end using local storage, cookie, etc. (Neglecting security issue or others, since this is just a toy project.) But I'm wondering if there is a way to do this in the back-end without using user authentication. Any ideas? Thank you very much in advance :) -
Static css in Django works unstable
I have css with following content in ecommerce/ecommerse/static/scc folder: body {background: #68951c;} h1 {color: #000000;} When i want to change the color of background, it changes in PyCharm, but it isn't changes on the web page even when i change a color in BOTH 1) ecommerce/static/scc and 2) ecommerce/ecommerse/static/scc manually. Even though command "python manage.py collectstatic" had run and server had re-run it is needlessly. Only one effect - when I ctrl+X following string in html page: <link rel="stylesheet" type="text/css" href="{% static 'css/base.css' %}"> then background evaporates. And when i insert the upper markup and refresh page, it appears again (upper markup contained in , in it is not working for some reason) -

How to check validation on two fields in a form?
Need to add an image to the form either by entering a link to the image, or upload a file from your computer.
