Reusable Chat Application for Django Developers

Hello everyone, A couple of months ago I was trying to check if I can use any of the apps that appear in Django Packages Chat section but it seems like none of them are maintained very well. So I decided to build an open source chat project based on

Hello! I need your help and assistance in my project. Currently we are developing project on the device, which is on arduino written on C low level, it is really difficult to handle do many things, we want to keep it as simple as we can, everything will rely on to the our web app(Django).

Thanks a lot, Simon! The delete and create sounds like the perfect solution in my case, since I don't have a lot of permissions assigned. Will try it now on a test case. On Mon, Mar 18, 2019 at 3:53 PM Simon Charette wrote: > > Would the following strategy work? delete all app permission and

Re: Channels - Updating client when the long running celery job finishes

Can you give some pointers on how you do that? In particular, will the client be notified on the same web socket it established with Django server? On Mon, Mar 18, 2019, 6:07 PM Aldian Fazrihady wrote: > Hi Suresh, > > Yes, celery task can send websocket message to client/JS. > My celery task

Re: test if model object fits into QuerySet without executing SQL?

Hi, Note that Django querysets are lazy. So running: qs1 = MyModel.objects.all() As is, doing that doesn't execute any queries. If you want filtered objects, just add filter: qs2 = qs1.filter(color="blue") qs2 is not even evaluated yet. You need actually cause something that evaluates

Channels - Updating client when the long running celery job finishes

In my web application based on Django and Channels, the user makes a web-socket and send a JSON message. This initiates a celery task and a reference to the task is sent to the user. Now, I want to update the client when the results are ready. The possible solutions I thought were: 1. The

Thanks Simon! Two questions: a) Would the following strategy work? delete all app permission and use, create_permissions to recreate them b) How do I know to which db table a given permission points? Or does it point to a model? On Mon, Mar 18, 2019 at 6:38 AM Simon Charette wrote: > Hello
