Best practice for looping python script in Django
So I have an app design question I'm hoping someone can help me with. I am building a network automation app for my company and currently have a python script which runs on a constant loop every 15 seconds to check on the health of a few hundred network devices across the company, essentially just pinging out. As an FYI, the app is in a docker container and being deployed to an azure web app. The goal is to build a django app that interfaces with all this information so there is a nice little web front end to view the state of the network and run commands from. The problem is, when trying to get the looping function to be called from 'views.py' for my python script it just takes over the server, so now the website goes down while it's looping. I can't seem to run the forever looping python script and keep the django web server running at the same time. Is there a better way to do this with Django and a constantly looping python script? Should I take this particular script out of the django app entirely and host it separate in azure some how … -
Django Rest Framework - How to serialize reverse relation field
I have a CustomerSerializer which uses a reverse foreign key field images to return all associated Image objects. class CustomerSerializer(serializers.ModelSerializer): class Meta: model = Customer fields = ('id', 'name', 'images') read_only_fields = ('id',) This is what I get from the response: [ { 'id': 1, 'name': 'John Doe', 'images': [ 1, 2, 3, 4, ... ] } ... ] Question: Instead of just showing images as a list of ids, how can I show a different property i.e. name? The desired result would be: [ { 'id': 1, 'name': 'John Doe', 'images': [ 'foo.jpg', 'bar.jpg', 'foobar.jpg', 'lorem.jpg', ... ] } ... ] My first attempt - I replaced the reverse foreign key images with image_names from the SerializerMethodField() in order to select the field name, but I get a null value. class CustomerSerializer(serializers.ModelSerializer): image_names = serializers.SerializerMethodField() def get_image_names(self, obj): return obj.images.name class Meta: model = Customer fields = ('id', 'name', 'image_names') read_only_fields = ('id',) Additional Info Example models: class Customer(models.Model): name = models.CharField() class Image(models.Model): name = models.CharField() customer = models.ForeignKey( Customer, related_name='images', on_delete=models.CASCADE) Please let me know if anything is unclear and I will update the question. Thank you. -

Im trying to get an id for a comment for update, delete, and to count Upvotes and downvotes, everything was working fine until I began using Django-mptt in order to have reply-able comments.

Do I need background tasks in django channels or can I just call functions inside the consumer?
I've just started learning how to use Django Channels - I've followed the tutorial on the docs and a read a bit online. My use case is fairly simple, I'm working with the Web MIDI API and I want to send MIDI to the server and have it represented in JSON, so that the client can query it later. I was doing this over HTTP, but the MIDI data was getting sent too fast and too often for HTTP to keep up. Once the data is received by the consumer, am I OK to just call a python function on it to store it in a dictionary directly inside the consumer, I've got functions already written that could do this. Is this an acceptable way to do it, or do I need to use these Worker or Background processes I've read about. The functions are quite simple, so I figured this method would be OK, but is there any reason why I should avoid this? -
Django code throws render to response error even though I'm not using it?
I get this error: ImportError: cannot import name 'render_to_response' from 'django.shortcuts' (C:\Python34\lib\site-packages\django\shortcuts.py) But my code looks like this: from django.shortcuts import render, redirect, render_to_response def proratesearch(request): context = { 'queryset': ers, 'ers2': ers2, } return render(request, 'conversion/query.html', context) What am I missing.

How do I resolve a raise NoReverseMatch(msg) django.urls.exceptions.NoReverseMatch error in Django 3.1 on Mac OS Catalina?
I'm currently going through "Python Crash Course" by Eric Matthes. I'm on Chapter 19 trying to add a page to a web app where users can enter data.

Recurrent objects in Django
I need some help in order to manage adding a new feature on my website created in Django. I made a spendings tracker website where a user can add as many personalized spendings and budgets he/she likes but I have a problem. I want to make a user to have the possibility to create recurrent spendings and budgets. For example if a user creates a spending right now and he select to be recurrent the website should some how add in the next month the same spending at the same date.

Django forcing logout on form submission
I have a Django application being used by multiple users. Users have told me that sometimes they will submit a form and it will redirect them to the login view (logs them out). When they log back in, the form was successfully submitted, but it is a strange and annoying bug. I have tried to duplicate this, but I can't seem to reproduce this behavior. Sorry for the lack of information here, but I am hoping someone has either seen this before, or can point me in the right direction for de-bugging an error like this. Thanks in advance! A little more info that may be useful: -I am using Django 3.1, and am running this on a local ubuntu Virtual machine within a corporate network. The VM is using postgres, NGINX, gunicorn to serve the application. -
Django Foreignkey in MongoDB's EmbeddedField
I am using Djongo engine for MongoDB in my Django project. I have two tables # app/models.py # My Main Table class Questions(models.Model): questionId = models.UUIDField(default=uuid.uuid4, editable=True, unique=True) question = models.TextField() answer = models.EmbeddedField( model_container=Answers ) date = models.DateTimeField(auto_now_add=True, blank=True) User = models.ForeignKey(UserDetailTable,on_delete=models.CASCADE,related_name='userinfo') and # app/models.py # This table needs to be Embedded in Questions Table class Answers(models.Model): answerId = models.UUIDField(default=uuid.uuid4, editable=True, unique=True) answer = models.TextField() date = models.DateTimeField(auto_now_add=True) User = models.ForeignKey(UserDetailTable,on_delete=models.CASCADE) class Meta: abstract = True I want to embed Answers in the Questions table. But I am getting this error django.core.exceptions.ValidationError: ['Field "App.Answers.User" of model container:"<class \'App.models.Answers\'>" cannot be of type "<class \'django.db.models.fields.related.ForeignKey\'>"'] I know this error is because I am using User = models.ForeignKey(UserDetailTable,on_delete=models.CASCADE) in Answers which is itself an EmbeddedField on Questions. How Can I solve this error? As there will be multiple answers from different users on the same question and with ForeignKey it will be simple to show the user's info along with his/her answer. I have also looked djongo's docs but couldn't find anything. Any help would be appreciated. -

How to group by and count in a subquery with Django's ORM?
I have a table map(id, key, value) from where I would like to select the keys that have same value. In SQL I could do SELECT key FROM map WHERE value IN (SELECT value FROM map GROUP BY value HAVING COUNT(*) > 1); I tried to translate it into Django's ORM style from django.db.models import Count Map.objects.filter(value__in=Map.objects.values('value').annotate(count=Count('value')).filter(count__gt=1)).values('key') But it fails because the subquery in the __in filter returns two columns, the selected value column and a column for the count: SELECT "map"."key" FROM "map" WHERE "map"."value" IN (SELECT U0."value", COUNT(U0."value") AS "count" FROM "map" U0 GROUP BY U0."value" HAVING COUNT(U0."value") > 1) How can I remove the uneeded count column from that subquery? -

How to disable VSCode's Explorer opening directory of opened file?
I'm using VSCode (1.47.3) on Ubuntu Bionic with the MS Python Extension Pack. I really want to disable the feature whereby Explorer decides to open the parent folder of the file I have just opened and allow me the control to open this folder manually (if I want to, which I rarely do). Scenario: I have some app-specific .py files open and Explorer shows my app's folder: "app" - all good. I navigate to a DJango dependency e.g. models.Manager when suddenly Explorer automatically shows the folder: site-packages/django/db/models - which I don't to happen. I didn't ask it to happen. In order to go back to the context of my top-level "app" folder, I have to scroll 100km back to where I was! I just want Explorer to stay in my "app" directory, regardless of what other files I may open. I only opened the DJango dependency for context/reference. I have no intention of editing that file (obviously) so I don't need any other DJango context. If I want to open a parent directory of a random file I've opened, I'll do that myself. How can I disable VSCode from doing this? Is there some JSON config I can modify? -

How to create objects of forms through Django Admin
I have a problem that I need to solve. I have no clue what to search or how to approach the problem. I want with the help of Django, create my "own" custom forms through Django Admin so I can use these as Objects. For example through Django Admin I want to for example press a button "Create new form" and select what new field I want to use, for example I want to have one field of charfield, and two fields of datefield. So it will create a new form, and then next time when i press that button I want to create a different one, one with IntegerField and one with charfield. What things should I look into to solve this problem? I have already knowledge in Django but I have no idea what to use to solve this perticular problem. I have read through the documentation. -

What do we have: Django app hosted on Pythonanywhere with sqlite db initialized MySql DB activated on Pythonanywhere (it provided me with db name, pasword and host - everything that I need to setup settings.py) pip install mysqlclient finished successfully python manage.py makemigrations - DONE python manage.py migrate - DONE mysql console on Pythonanywhere shows all my tables created but restarting app causes pythonanywhere error page and link to error log 2020-08-15 17:22:56,536: Error running WSGI application 2020-08-15 17:22:56,569: django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module. 2020-08-15 17:22:56,569: Did you install mysqlclient? So the question is how could it be possible? As i got it right migrations are used mysqlclient to manipulate DB, how can it be not installed? Might be someone did face with similar issue? -
