Django + Esputnik (part 2) – Error: Cannot transform message content

Long story short, something is wrong with your dynamic tags. Two rules need to be applied:

1. Use ‘ but not “

Right version:

$!data.get(‘your_variable’)

Wrong version:

$!data.get("your_variable") 

2. The tag was broken by another tag

Open the HTML editor of the entire message and Ctrl+F $!data.get(‘.

All the tags need to look like this $!data.get(‘something’). BUT! You may see something like this:

$!data.get(‘something' <span><strong>)

And these <span><strong> are what causing the error.

[Note] ‘ChatConsumer’ has no attribute ‘as_asgi’ – Sloppy development

Following Channels’ docs I encountered yet another error the solution to what was not obvious right off the bat.

Ditch Channels.

The End.

This was my original post in October 2020 and I stand by it.

You can make your project work with Google Firebase - it handles signals well enough. Yes it is primarily used by mobile developers, but overall it is fine for web too.

I spent trying to install Django Channels on my local Linux 18.04, and I kind of made it work, but then I had to deploy it... And as a professional backender you don't want to let people down.

I decided to try Channels because my Python-related friends talked about it. But days into the trouble I asked my friend about a certain step and he asked me in return "oh so [you use it because] they fixed Channels since two years ago?". I as like ??????????????????. So that moment I ditched it. Too much time wasted, but I like the result I achieved with Firebase.

What I am saying - Firebase is fast and universal. In a matter of days I managed to make and deploy an internal Customer Support chat service that connected mobile app users and a support from the web.</p>

I will be writing a new series on Django + Firebase, and this post is pretty much a short introduction.

Django + Froala: style fix

Froala provides a great WYSIWYG editor for Django admin, but on page the styles for django-froala-editor didn’t work no matter what I tried. It didn’t look like what I get at all.

At some point, it was clear that providing a quick fix would suffice. I made a short style sheet to make these styles work on Django templates. It is my example that fits my needs. I don’t eliminate the fact that I failed to find an organic solution to this via package files.

Copyable table column // 1-minute guide 🌺 🐋

I like Excel for the ability to copy the whole column, and HTML tables don’t normally provide that. As a result, tons of time and nerves spent on copying cell by cell, cell by cell…

My friend and colleague (who btw likes HTML tables but in Adobe Dreamweaver graphic mode) needs a lot of data searched and sorted and put in table, but also copyable. Hm…

So, let’s make HTML tables great!

sidenote In my examples, tables are light blue, and cells are pink.
