QUESTION
I'm trying to create custom FilterSet for filtering nearby users by distance using django-filter
For example if I send
GET /api/list/?distance=300, I want to get all nearby users who are lower or equals to 300m far away
My model has 2 fields:
...ANSWER
Answered 2022-Mar-29 at 12:58I would recommend using the existing tools that solved this problem a long time ago. Doing accurate (and efficient) distance calculations on an irregularly shaped sphere is more complicated than this.

Hi all!
New in Django, and confused, help is appreciated! I've created a table, , thanks to a stackoverflow users, like:
Organization Total amount of appeals Amount of written form appeals Amount of oral form appeals Organization 1 3 1 2 Organization 2 2 1 1Have three models:
...ANSWER
Answered 2022-Jan-31 at 15:14The most general way to define a complicated filter is to use the method argument. I can't say I completely understand your problem, but you can apply any filter for which you can dream up a queryset in this way. In outline:
QUESTION
I have a Item model with a numeric number field. This number field defaults to null.
ANSWER
Answered 2022-Jan-01 at 04:51Well, the only solution I can think of is to pass the min range, max range, and is_null boolean into a single char field then convert it into the 3 individual filters for actioning.
So the query URL will look like ?master_num=1-10-1 for range 1 - 10 incl. None and ?master_num=1-10-0 for range 1 - 10 excl. None.
QUESTION
This appears to be a common error, and I have checked all the solutions I could find (there are only about 4 and almost all of them involve misconfigurations). I am NOT using heroku, but I AM using docker. I am using the docker images python:3.9.7 and postgis/postgis:10-3.1-alpine.
My Dockerfile contains the following line:
ANSWER
Answered 2021-Nov-08 at 18:43Solved! This was due to another configuration overriding the DB settings. I was very adamant that it was not a configuration issue, and I'm sorry. I verified this by running the admin shell in the running django app and checking settings.DATABASES. (The other override was django-prometheus, if you're curious.)

QUESTION
I am using the django-filter module. I would like to get all objects where the year is 2011 or greater.
this is my setup ...
Actual behaviour:When I enter a year, then I get the error message: "Enter a valid date." and the queryset is unchanged.
I tried entering a date instead of the year, but then the whole page fails with the error message
Field 'None' expected a number but got datetime.date(2011, 1, 1).
ANSWER
Answered 2021-Sep-11 at 15:24Your billing_year is not a DateFilter, but an NumberFilter. Indeed, a year is an integer, not a date. This thus means that we can filter with a given number (for example 2011) on the year of that date:
QUESTION
I want to retrieve data filtered by user and category.
I'm using Django Rest Framework.
models.py
...ANSWER
Answered 2021-Sep-06 at 09:40Yes it is possible to filter with many parameters. Django Rest Framework provide us many options to achieve this goal. I'll show you one of them : Filtering against query parameters.
You can override .get_queryset() of your class based view to deal with URLs such as api/practice-filter-subcategory-user?user=1&category=Math
QUESTION
I have a Dockerfile, docker-compose.yml and a run.sh script that runs my django server with so many configurations that work just fine and everything is tested but... the server does not run at the end on python3 manage.py runserver 127.0.0.1:80 command inside run.sh bash script.
I searched everywhere but didn't find any solution at all. If someone can guide me what the problem is, I would be so thankful because I literally lost two days of my life in the process of running a simple django server with docker-compose.

ANSWER
Answered 2021-Sep-01 at 10:09Maybe python3 manage.py runserver 127.0.0.1:80 already run, just the log did not be flushed.
One option could be add PYTHONUNBUFFERED=1 to docker-compose.yaml to let python not buffer output:

Install django-filter
You can use django-filter like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
