Docker Image > 1GB in size from python:3.8.3-alpine
I'm pretty new to docker and, although I've read lots of articles, tutorials and watched YouTube videos, I'm still finding that my image size is in excess of 1 GB when the alpine image for Python is only about 25 MB (if I'm reading this correctly!). I'm trying to work out how to make it smaller (if in fact it needs to be). [Note: I've been following tutorials to create what I have below. Most of it makes sense .. but some of it feels like voodoo] Here is my Dockerfile: FROM python:3.8.3-alpine ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 RUN mkdir -p /home/app RUN addgroup -S app && adduser -S app -G app ENV HOME=/home/app ENV APP_HOME=/home/app/web RUN mkdir $APP_HOME RUN mkdir $APP_HOME/staticfiles RUN mkdir $APP_HOME/mediafiles WORKDIR $APP_HOME RUN pip install --upgrade pip COPY requirements.txt .

Django deployment with Zappa - root URL is wrong
I have successfully set up a Django app following a Zappa tutorial I found. However, the problem is that Zappa deploys my app to the location: https://some-aws-address/devel where "devel" is the name of my particular Zappa deployment. The problem with this is that, at this position, I have pages that have links on them beginning with a '/' that map to: https://some-aws-address/ and not (as I would want): https://some-aws-address/devel For example, in one of my template files I have a link on an image: <a href="/"><img src="{% static 'images/main/ryzosens-logo-white-background.png' %}"></a> where the href="/" always maps to https://some-aws-address/ I don't want to have to do some hack to get my root URLS to map to https://some-aws-address/devel, so the question is: What must I have in my Django settings (or elsewhere) so that my URL root '/' maps to the HTTP endpoint that Zappa creates? Many thanks in advance! -
How to query records from a nested M2M field in Django?
I'm trying to understand how to get a QuerySet for a nested ManyToMany relationship in Django. Imagine models that look something like this: class Collection: ...fields... class Group: collections = ManyToMany(Collection) class Account: groups = ManyToMany(Group) I can't quite figure out how to query all of the collections for a given account. E.g. something similar to: account.groups.all().values('collections') But the above query gives me a generic QuerySet of just the PKs of the collections, and I'd like a CollectionQuerySet containing the full models. -

Django login - "Cannot force an update in save() with no primary key"
I have implemented the standard Django login in the following manner: from django.contrib.auth import authenticate, login, logout def login_request(request): username = password = "" if request.POST: username = request.POST["username"].lower() password = request.POST["password"] user = authenticate(username=username, password=password) if user is not None: if user.is_active: login(request, user) return redirect("../..") return render(request, "login.html", context={"error": "TRUE"}) return render(request, "login.html", context={"error": "FALSE"}) For most users, this has worked fine. However, for some users it has been throwing the following error: ValueError at /login/ Cannot force an update in save() with no primary key. This error is sourced back to the user.save(update_fields=['last_login']) in django/contrib/auth/models.py. I have been unable to determine why this error is occurring, and why it happens to some users and not others. I've looked closely, and been unable to find anything that differentiates between users who have had this problem and those who haven't. -

Why is my django application not serving .css files?
I have an issue with serving a specific css file in my django app and I can't seem to find the solution to it, hopefully someone can help. I have a website PersonalWebsite and in there I have three apps, the important one being the dashboard. I decided to separate the static files of each app and then also the static files of the base website so my folder structure is like this: PersonalWebsite | |static |PersonalWebsite | |css | style.css |fonts | font.ttf |dashboard | |static |dashboard |css | style.css When I open up the website I can see all files from the static/PersonalWebsite are being served, however the ones from static/dashboard are not. Could anyone provide some insight as to what is wrong? I have run the collectstatic command several times and that one detects the file and I see it being copied into the root folder. These are my static settings. I added boot because in that one I have bootstrap downloaded. STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'root') STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static/'), os.path.join(BASE_DIR, 'boot/'), ] -

Django annotate value based on another model field

So I can get the Specialty name related to a specific Case instance using something like this: my_pk = #some number here... my_case_judge = Case.objects.get(pk=my_pk).judge my_specialty_name = Specialty.objects.get(sys_num=my_case_judge) I know this sounds really weird but I can't change the underlying schemma of the tables, just work around it with sql and Django's orm.

Mutate and query multiple apps having same database schema in GraphQL Django app
I am new to django and graphQL. Am working with 2 databases which have exact same schema. Problem is - My query and mutations are executing only on one database.

I process them (lower case conversion + remove punctuations) and store them in OutDb. Similarly, I need to mutate and query OutDb. I have correctly configured ops with 2 database using dbrouters.

Django tests failing after unique_together error catch
Writing my tests for a certain part of my Django application I am trying to test if a unique_together error message pops up on my API. This is the test I am running: re = self.c.patch('/api/me/dashboards/' + str(default_id) + '/', {'widgets': [{ 'name': 'Testwidget 2', 'type': 1, 'coord_x': 1, 'coord_y': 1 }]}, content_type='application/json') self.assertEqual(500, re.status_code) self.assertEqual( re.content, b'{"message":"UNIQUE constraint failed: dashboard_widget.coord_x, dashboard_widget.coord_y, dashboard_widget.dashboard_id","status":500,"error":true,"detail":""}') It works fine, but after that no matter whicht test I am running it states django.db.transaction.TransactionManagementError: An error occurred in the current transaction. You can't execute queries until the end of the 'atomic' block. If I remove all tests after this, there is no error message or similar. The API endpoint works otherwise, it is just the test that messes up. Also I did this with a similar test, which should raise a Validationerror and this test behaves the same: Everything is fine but the subsequent test is failing with the error.
