Django Admin Inline & TabularInline – Appending ordered text fields with a sql database structure
I have read and have tried some of the examples in https://docs.djangoproject.com/en/3.1/ref/contrib/admin/ in regard to appending additional objects.

I want to get that working first; but down the road I also want to do the following: Ordered list of Answers: that is, ranked ordering to the questions.

What would be the most optimal/logical way to store answers to pre-determined yes or no questions to the database
I've been thinking: What would be the most optimal/logical way to store user answers to pre-determined 'yes or no' questions to the database. Note: the question model is in a one-to-one relationship with the user model. No. of Questions: 25 A: Store the questions as straight boolean variable/column to the database. Per user x 25 columns B: Store the questions as 'question' and boolean 'answer' to the database. Per user x 25 question rows, 1 user x 25 answer rows Which is faster? Please share your thoughts. -

How to achieve multiple output representations in Django Rest Framework Serializer
I am trying to use the Django Rest Framework(DRF)'s serializer with Djnago models with some PostgreSQL fields. I understand that by overriding to_representation() method of the serializer, the outgoing (serialized) data format can be changed. Is there any way to have multiple outgoing representations in DRF serializers? For example, what I am trying to achieve is something like this. from rest_framework import serializers class MySerializer(serializers.Serializer): first_name = serializers.CharField(max_length=20) last_name = serializers.CharField(max_length=20) def to_representation_1(self, instance): return { 'first_name': instance.first_name, 'last_name': instance.last_name } def to_representation_2(self, instance): return { 'firstName': instance.first_name, 'lastName': instance.last_name } def to_representation_2(self, instance): return { 'name': f'{instance.first_name} {instance.last_name}', } Is there such support in DRF? If no, what is the recommended way to achieve this keeping the possibility of nested serializers in mind? -

Django REST API: Deduplicating authorization checks in test code

Djangon 2.2 filtering a single data set across pages
In my django app I have a main page which shows the numbers of books for each genre in a table and it also has a search bar that allows filtering of the books by Genre, title or author which then posts the data to a search page and allows viewing of the book entries in a table. On the search results page I want to then be able to additionally filter the same set of data further using an extended set of search bars - including the original filters, plus filters such as publish date and rating. In the extended search I would not want to lose the original search - so for example if I search for horror genre on the main page and then wish to filter that further to only include highly rated books on the sesrch page I dont want to lose the horror filter if I don't add the filter again. Is this possible? Essentially I'm wondering if you can apply different filters to a single view? Thank you in advance -
How to programatically post to Django Rest Framework endpoint?
I've got an endpoint built with Django Rest Framework. I now want to separate the ingress and the parsing. So I created an endpoint which basically writes the received string of data to a textfield in. I now create a management command which continuously loops over that table and parses the contents. So I get the I raw string from the ingress table, and I now want to post this to the DRF endpoint programmatically. I've done this many times in my unit tests. But I'm unsure how I can do this from the management command. I can use the same code as I do for test requests, but it seems weird to use testing code in production. People might suggest to manually use the serializer, but there's also things happening in the viewset which I need. Does anybody have a good idea how I would be able to do this? -
Vscode with beautify does not indent django html templates
I am looking to format my django templates in the same manner as HTML. Beautify ends up treating my templates like text, and not indenting their contents. For example, after formatting my code looks like this: <head> {% if title %} <title>Django Blog - {{ title }}</title> {% else %} <title>Django Blog</title> {% endif %} </head> Instead of <head> {% if title %} <title>Django Blog - {{ title }}</title> {% else %} <title>Django Blog</title> {% endif %} </head> I currently have Beautify & Django extensions installed, running on VSCode and WSL. settings.json VSCode: "files.associations": { "**/*.html": "html", "**/templates/*/*.html": "django-html", "**/templates/*": "django-txt", "**/requirements{/**,*}.{txt,in}": "pip-requirements" }, "emmet.includeLanguages": { "django-html": "html" }, "beautify.language": { "html": [ "htm", "html", "django-html" ] }, "[django-html]": { "editor.defaultFormatter": "HookyQR.beautify" } Why isn't beautify correctly formatting / indenting my templates? How can I resolve this behavior? -
How to handle management command exception in django app?
I'm working on a django app which is based on consuming an external ZeroMQ message queue - it listens to the queue all the time, processing the messages and saving the outcome in the database. The data will be in the future made accessible to the users by API. Currently I'm running it by a custom management command listen, which runs an infinite loop and it works fine. However, whenever some kind of error appears (and they will sometimes appear, it's an external data source) the command dies. What's the best approach to handle such errors? Things I'm considering: Bash script which will restart the command on failure Big Try... except Exception in the main command function (but this seems extremely wrong) Some custom exception handler - the problem is that the recommended handlers only handle errors in views/requests, and my command is not a view/request, it just runs. Any advice would be useful, maybe it's a misuse of the management command?
