Should i dockerize Django app as a root user? If yes how can i set up non-root user for Django? Because in node.js app should have USER:node which is a better practice. Code example from official docker page which does not include non-root: FROM python:3 ENV PYTHONUNBUFFERED=1 WORKDIR /code COPY requirements.txt /code/ RUN pip install -r requirements.txt COPY . /code/ -

I have a form like <form id="..." class="...">. Inside this form, I have 2 buttons, which are tracked with JS like: function one(event) { $.ajax({ type: 'POST', url: "...", data: { 'csrfmiddlewaretoken': csrf[0].value, }, ... }) } function two(event) { $.ajax({ type: 'POST', url: "...", data: { 'csrfmiddlewaretoken': csrf[0].value, }, ... }) } btn1.addEventListener('click', one) btn2.addEventListener('click', two) So, everything works fine.

Django: Null value in column "category_id" of relation "APIs_api" violates not-null constraint
I'm trying to save data into my PostgreSQL database but I seem to get an error on the category_id column that it's null. All other data seems to be submitted correctly but I keep getting this error. Null value in column "category_id" of relation "APIs_api" violates not-null constraint DETAIL: Failing row contains (1, Twilio SMS, Twilio's Programmable SMS API helps you add robust messaging cap..., Twilio's Programmable SMS API helps you add robust messaging cap..., 1, null). The 1 in this case refers to the User ID. Referencing the category_id seems to be the problem. The category in question is SMS with an ID of 34. So the category_id should be 34, since I have 47 categories. I can't find any solution online as many tutorials have the admin input items from the admin dashboard that have a Category as a Foreign Key. I want to achieve these through a form. I have 2 models, API & APICategory Here is my Models.py from django.db import models from django.contrib.auth.models import User from django.template.defaultfilters import slugify class API(models.Model): api_name = models.CharField(max_length=30, default='', unique=True, verbose_name="API Name") short_description = models.CharField(max_length=250, default='', unique=True, verbose_name="Short Description") full_description = models.TextField(default='', unique=True, verbose_name="Full Description") category = models.ForeignKey(APICategory, on_delete=models.CASCADE, … -
How do I edit a form with Imagefield without updating Photo?
I've tried numerous ways to fix this error and I can't seem to solve it. I have a form for a user profile, the profile automatically gets created when the user registers and they receive a default photo until they upload their own.

I got a probelm when I was trying to deploy my Django project to Digital Ocean. I followed that tutorial step by step, but it doesn't work on gunicorn
A little background-- Our deployment process is now on using gunicorn, so that means specifically our .wsgi file will be used. But since we never used our .wsgi file when we ran it on our local pycharm to view the site, we figured it would still work when we tried to connect to the server (We have a .wsgi file). However, every time we try to connect the .wsgi file, we get too many errors, and we do not know why. We are very close. What I would like for you to do is please watch this video below, and please tell me why we are running into this error, if possible. Here's the resource we used. https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-20-04 -

Does not reflect current user in comment
Hello I am new in the community and in the world of programming so I hope you can excuse my ignorance. I'm creating an Instagram-style application with Django 3.2.5. Where users have profiles to visit and upload photos. I am implementing a commenting system, I have it almost finished or so I think ... Turns out I am stuck ... When generating the comment as a user with a registered profile, the comment is rendered as if it were anonymous. I have investigated and it happens that in the model of the comment I made a relationship with user and profile giving the null parameter as true. When removing this parameter and resubmitting a comment on a post I get an error of 'Not Null Constraint Failed' for profile_id and for user_id (The image shows the first comments made from the admin. And the last one with the null = true parameter in the model) Sample picture Here I leave my models.py class Comment(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name='comments') user = models.ForeignKey(User, on_delete=models.CASCADE) profile = models.ForeignKey(Profile, on_delete=models.CASCADE) text = models.TextField(max_length=200) created_date = models.DateTimeField(auto_now_add=True) class Meta: ordering = ['created_date'] def __str__(self): return self.text Here I leave my views.py def create_comment(request, pk): … -
