Django deployment and virtual environment
I am aware that there are many questions regarding Django and virtual environments, but I cannot wrap my head around the use of virtual environments with respect to deploying my Django app (locally) via uwsgi/nginx. My setup includes a virtual environment (with Django and uwsgi), my Django app, nginx and PostgreSQL. The app was created before the virtual environment, and I applied only a single change to manage.py: #!/Users/snafu/virtualdjango/bin/python3 When I start up the uwsgi located in the virtual environment (with the appropriate .ini file), everything works right away, but I wonder why. I did not need to fiddle around with the $PYTHONPATH, or append the site packages directory to the system path in manage.py, or activate the virtual environment at any point (apart from the initial installation of packages), although the boilerplate comment in manage.py explicitly mentions an inactive virtual environment as a possible reason for an import error. -

Custom user model in Django and super user
I am using Django as backend for my mobile app. When creating users info I need the following info:name, DoB and firebaseUID. Please note that I do not want their email or password. But I want to create superusers who act as admins and want the superusers to be created using email and password. So I am not sure if I have to: Create a custom user by extending AbstractBaseUser and have a user manager attached to that custom user OR Create a custom user by extending AbstractBaseUser and then create another Django user class which is only for superusers. I implemented option 1 with the below code, but I get the following error: "TypeError: MyUserManager.create_superuser() missing 1 required positional argument: 'email'" Also when I am creating superuser, Django is asking for name, firebaseUID and DOB fields although I want to create superusers only email and password fields. from django.contrib.auth.models import AbstractBaseUser from django.db import models from django.utils import timezone class MyUserManager(models.Manager): def _create_user(self, email, password, **extra_fields): """ Creates and saves a User with the given email and password.

Here's the test.py from rest_framework.test import APITestCase, APIRequestFactory from rest_framework import status from django.urls import reverse from .views import PostViewSet from django.contrib.auth import get_user_model User = get_user_model() class PostListCreateTestCase(APITestCase): def setUp(self): self.factory = APIRequestFactory() self.view = PostViewSet.as_view({"get": "list", "post": "create"}) self.url = reverse("post_list") self.user = User.objects.create( email="testuser@gmail.com", name="testuser", password="pass" ) def test_list_posts(self): request = self.factory.get(self.url) response = self.view(request) self.assertEqual(response.status_code, status.HTTP_200_OK) def test_create_post(self): sample_post = { "title": "sample title", "body": "sample body", } request = self.factory.post(self.url, sample_post) request.user = self.user response = self.view(request) self.assertEqual(response.status_code, status.HTTP_201_CREATED) And here's the view: from rest_framework import viewsets, status from rest_framework.response import Response from django.shortcuts import get_object_or_404 from .serializers import PostSerializer, LikeSerializer from .models import Post, Like class PostViewSet(viewsets.ModelViewSet): serializer_class = PostSerializer queryset = Post.objects.all() def get_queryset(self): posts = Post.objects.all() return posts def get_object(self): post = get_object_or_404(self.get_queryset(), pk=self.kwargs["pk"]) self.check_object_permissions(self.request, post) return post def create(self, request, *args, **kwargs): try: post = Post.objects.create( title=request.data.get("title"), body=request.data.get("body"), author=request.user, ) post = PostSerializer(post) return Response(post.data, status=status.HTTP_201_CREATED) except Exception as ex: return Response(str(ex), status=status.HTTP_400_BAD_REQUEST) def list(self, request, *args, **kwargs): posts = self.get_queryset() serializer = self.get_serializer(posts, many=True) return Response( data=dict(posts=serializer.data, total=len(serializer.data)), status=status.HTTP_200_OK, ) That's what I get: … -
Way to show latest 4 blog posts on my page
I want to be able to show the latest 4 blog posts only. I can't seem to get them to show. Any help would be greatly appreciated. Here is my code: Models.py class BlogPost(models.Model): blog_title = models.CharField(max_length=48) blog_article = RichTextUploadingField(null=True, blank=True, default="ici") blog_image = models.ImageField(null=True, blank=True, upload_to="images", default="default.png") blog_date = models.DateField(auto_now_add=True) blog_published = models.BooleanField(default=False) blog_featured = models.BooleanField(default=False) def publish(self): self.blog_date = timezone.now() self.save() def __str__(self): return self.blog_title Views.py def blogTest(request): posts = BlogPost.objects.filter(blog_date__lte=timezone.now()).order_by('blog_date') context_blog = {'posts': posts} return render(request, 'blogtest.html', context_blog) def latestPosts(request): latest = BlogPost.objects.filter(blog_date__lte=timezone.now()).reverse()[:3] return render(request, 'blogtest.html', {'latest': latest}) Template <div class="blog-post-container"> <div class="row"> <h1 id="lastest-blogs-title" style="text-align: center;">Latest Blogs</h1> {% for latestpost in latest %} {% if latestpost.blog_published is True %} <div class="col-md-4" id="bloggrid1"> <hr> <div class="blog-post"> <div class="blog-content"> <img class="blog-img"src="{{latestpost.blog_image.url}}"alt="My image"/> <h2 class="blog-title">{{latestpost.blog_title}}</h2> <hr id="blog-hr" style="width: 90%" /> <article class="blog-article"> <p>{{latestpost.blog_article|truncatechars_html:265|safe}}</p> </article> <a href="{% url 'viewblog' post.id %}"class="btn btn-secondary"type="button"class="blog-button">Read More...</a> <p class="blog-date">Posted on: {{latestpost.blog_date}}</p> </div> </div> </div> {% endif %} {% empty %} <h3>No Blog Uploads</h3> {% endfor %} </div> </div> </div> I have followed many other tutorials but I can't seem to see what I'm doing wrong here. -
Rollup Not Tree Shaking D3.js Correctly, Even With sideEffects Flag Set To False?
When using rollup v3 to bundle my npm project that uses the D3.js v7 library to an es6 module for use on the browser, I am ending up with a lot of extra unnecessary code from D3.js in the produced bundle. This happens even with the sideEffects flag set to false in package.json, which seemed to be the solution to this issue when it was discussed a couple of years ago on this github issue: https://github.com/d3/d3/issues/3076 . While treeshaking is definitely occuring, I'm still ending up with almost 1000 lines of code in my bundle from just importing one function (select from d3-selection). Besides setting the sideEffects flag to false in package.json, is there anything else I need to do? I also tried setting moduleSideEffects to false in rollup.config, but this didn't seem to have any additional effect. I have created a very simple example npm project that reproduces the issue. It is on github here: https://github.com/SpechtacularDave/rollupd3treeshake , or you can view the the example input index.js, package.json, and rollup.config.js below (but see the repo if you want to take a look at the output bundle since it's almost 1000 lines long). // index.js import {select} from "d3-selection"; select('#someid'); // … -
How are environment variables processed from ".env" file if Django project deployed to AWS from Github?
I have a Django project deployed on AWS EBS from a Github repo. My secret key is kept on a .env file. I've included the following: settings.py from decouple import config "SECRET_KEY" = config.("MY_SECRET_KEY") requirements.txt python-decouple==3.7 .env MY_SECRET_KEY = "THISISMYSECRETKEY-THISISMYSECRETKEY-THISISMYSECRETKEY" Since I've include .env inside my .gitignore file, the .env is not being pushed to Github. When I try to deploy my project I keep getting an error: "web: decouple.UndefinedValueError: SECRET_KEY not found". The project runs fine on a local server. Any advice would be appreciated. -

How could I configure it so that the user who is logging in is a user of a PostgreSQL database manager?
I am developing a web application, I would like to know how I can configure it so that the user who is logging in is a user of the PostgreSQL database manager, generally there is a superuser who has permissions to freely manage all the databases, but other users with a lower hierarchy can be added, so I would like it to be possible to access as such with those users created in the DBMS. I use python as programming language and django as framework. I really have no idea how to achieve this functionality, I'm starting my studies, I want to surprise my database teacher with something different from the rest of the students, and I would like someone to help me with this, I don't expect a complete solution, just a guide and references to be able to achieve what is proposed
