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).

welcome to Docker! It can be quite the thing to wrap one's head around, especially when beginning, but you're asking really valid questions that are all pertinent

Reducing Size How to

A great place to start is Docker's own Dockerfile best practices page:

https://docs.docker.com/develop/develop-images/dockerfile_best-practices/

They explain neatly how your each directve (COPY, RUN, ENV, etc) all create additional layers, increasing your containers size. Importantly, they show how to reduce your image size by minimising the different directives. They key to alot of minimisation is chaining commands in RUN statements with the use of &&.

Something else I note in your Dockerfile is one specific line:

Django provide a import_id_fields so we can specify fields that we wants to import. Without it, it always look for a field ID.

The solution was to emcapsulate my class with resources.ModelResource and specify import_id_fields.

As already remarked in the comments, one of your dependencies (activiti-engine) has an alternative implementation of the EL Specification: JUEL.

This is, in my opinion, an error in activiti-engine's POM: the project should not depend on a specific EL implementation, just the EL API.

You can correct it by explicitly excluding the JUEL dependencies from your project:

First of all, this navbar is added by Django 3.1+ and not by any other 3rd part packages.

Copy & Pasting from Django 3.X admin showing all models in a new navbar,

From the django-3.1 release notes,

The admin now has a sidebar on larger screens for easier navigation. It is enabled by default but can be disabled by using a custom AdminSite and setting AdminSite.enable_nav_sidebar to False.

So, this is a feature that added in Django 3.1 and can be removed by settings AdminSite.enable_nav_sidebar = False (see How to customize AdminSite class)

How to fix irregular styling?

You don't have to edit any CSS or HTML file to fix the styling, because Django comes with a new set of CSS and HTML, which usually fix the issue. (That is, it is not recommended to alter the styling file only for this)

If that doesn't work for you, it might be because of your browser cache.

If you are using Chrome,

Go to the admin page
Ctrl + Shift + i and select Network tab and then tick Disable Cache
Refresh the page

How to correctly install PyICU on Heroku?

Asked 2021-May-28 at 00:31

I am trying to deploy my Python app on Heroku, but have been unsuccessful. It seems that a problem is occurring with the PyICU package, which I'm unsure how to correct. I've confirmed that this is the only issue with my deployment; when I remove PyICU from my requirements file, everything works. But of course my site can't work without it.

Can anyone please guide me in how to correctly install this package on Heroku? I've tried various methods, including downloading the .whl file and then adding that to my requirements file, but then I get another error:

ERROR: PyICU-2.7.3-cp38-cp38m-win_amd64.whl is not a supported wheel on this platform. I don't understand why - it's the correct Python and os version.

Here are the relevant excerpts from the build log:

Answered 2021-May-26 at 15:55

Why are you using the windows wheel (PyICU-2.7.3-cp38-cp38m-win_amd64.whl)? You probably need a manylinux wheel.

You can also try pyicu-binary package.

Exporting the filtered data from a django table

Asked 2021-Mar-22 at 18:26

I am using django-filter and django-import-export. I can build an HTML table and filter it using django-filter just fine, but I want the user to be able to export the filtered table, not the whole table. (That is, this is not through the admin feature.)

I suspect the issue is I have one view for the list itself, but the export is in another view, and I can't seem to pass the filtered queryset to the export view, and I can't figure out how to do the export and filter on the same view. They're both GET requests. I feel like I'm missing something very very basic here.

Starting with baby steps is a great idea. I would suggest get a standalone script working first so that you can check the file can be read and imported.

If you can set breakpoints and step into the django-import-export source, this will save you a lot of time in understanding what's going on.

Install tablib

You can install using 'pip install tablib' or download it from GitHub, PyPI.
You can use tablib 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.
