I think what he meant is 'session' in django.

Probably can take a look at this: https://docs.djangoproject.com/en/4.0/ref/request-response/

For example, django app wants to know who is the current user, can use something like:

`request.user`

Python is a programming language so there's no such thing as a "session
for login and logout".

If you want someone to help you, you should try to clarify what you
actually need help with. I assume you mean something with Django
sessions but it's impossible for me or anyone else to know exactly what
kind of issue you need to solve.

Kind regards,

Re: uvicorn and ASGI

Hi Dan. 

Your question interested me so I went looking. The page you link to further links to the uvicorn documentation which seems to indicate their suggestion for production deployments is to use gunicorn and the uvicorn worker. 

Their rationale seems to be that uvicorn is great at running an event loop and operating asynchronously but the worker process management including increasing and decreasing them and hitless upgrades were managed by gunicorns more mature features here. 

The way I am conceptualising the core benefit here is multi core machines where workers can be thrown into different process threads to utilise all available cores while the asynchronous benefits improve parallelisation of requests where applied to reduce time to run particular views to completion. So they work together for best effect. 

https://www.uvicorn.org/#running-with-gunicorn

I am doing some work comparing various ASGI frameworks, SQL Alchemy, just writing the SQL, and that sort of thing, in order to determine what I think.  Speed isn't every thing, but speed is a thing.

Anyway, I was reading about this at https://docs.djangoproject.com/en/4.0/howto/deployment/asgi/uvicorn/ and it is curious that the advise is to run uvicorn as a work rather than a full ASGI server.  Can someone explain why this is necessary or better?

Thanks,

Hi Sencer, signals will be helpful only if you are auditing on certain models 

but if you are trying to audit a set of views then middleware will be a better choice since that will be more manageable

one good source when you have a question "is there anything in django that does X?" is to go to djangopackages.org.

Hi,

I've been planning to add audit logging to the project.

But, I can not decide which approach is the best;

Using signals or creating middleware?

Project needs to being log events on change of model object with these informations below:

- If a record is inserted, updated and deleted:

   - who is taking this action (ForeignKey)

   - what is the action (Choice)

   - which applications model object affected (ContentType)

   - affected object (Generic relation)

   - current data in json format

   - previous data in json format

Kind regards,

A good start would be to understand what the difference between square
brackets and curly braces is. The JSON format is very simple:

https://en.wikipedia.org/wiki/JSON#Syntax

So you actually want to convert your array to an object with anonymous
properties/members. That doesn't really make any sense and wouldn't be
valid JSON.

Of course you could write a dirty hack and do it anyway but I seriously
doubt that's really what you want.

Hope that helps.

Re: ComboBox

Thanks for the responses. 

rgam - I appreciate what you are saying. I think it is roughly what I am doing now, but it is a bit clumsy in that  the user (of a financial application) will typically have a list of regular  customers to select from, and also may have other customers that are one-off, or infrequent which they will not want to clutter their options list with but still need to record against a transaction.

Ryan - thanks, the datalist looks like it might be right option. I will look at custom widgets.

All the best - Phil

Hi

If any arbitrary text is allowable, then at the model level I'd just use a CharField. I wouldn't add a choices= argument to the field unless is the value is strictly constrained to those choice as other test would then fail validation.

At the Form level, I'm not sure. I'd probably work just mirror what the frontend needed.

Does that help ?

Hi all

I am converting a desktop application to Django web application. The desktop app uses comboboxes (editable dropdown/select). Is their any elegant way of applying the same functionality in Django? Stack Overflow etc. all seem to be about dropdown select lists only.

I can see ways of doing this with a Choicefield plus a separate Charfield, but is there a better way?

Re: ComboBox

The HTML element you probably want is a datalist[1]. There's no built-in Django support for datalist[2] so you'll probably need to create a custom widget.
