django-ex | Django Example | REST library

to build and run a local instance, im following the tutorial at https://haha.readthedocs.io/en/latest/install.html but i use the git repo https://github.com/readthedocs/readthedocs.org.git instead of https://github.com/rtfd/readthedocs.org.git for the "git clone" command, as the link in the tutorial does not exist. i am also using venv, and not virtualenv, as i was not able to make virtualenv work.

i then get to the step to run the following command

I have an input file

I have a script that loops through the rows of an external csv file (about 12,000 rows) and executes a single Model.objects.get() query to retrieve each item from the database (final product will be much more complicated but right now it's stripped down to the barest functionality possible to try to figure this out).

For right now the path to the local csv file is hardcoded into the script. When I run the script through the shell using py manage.py runscript update_products_from_csv it runs in about 6 seconds.

The ultimate goal is to be able to upload the csv through the admin and then have the script run from there. I've already been able to accomplish that, but the runtime when I do it that way takes more like 160 seconds. The view for that in the admin looks like...

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:

My django app deployed in heroku managed to show upload file form. However once I try uploading Excel xlsx file, it shows

I am building an Alpine based image of a Django application to connect with a MySQL db. For connecting with the database, I am using mysqlclient. For building the image, I am using docker-compose. When I do docker-compose build I get the respective error:

I'm usign django-excel library in my Django project, and I want to skip some rows before save it to the database using the save_to_database() method.

I have something like the following:

After running pip3 install -r requirements.txt

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:
