Re: Use Django to implement my GUI!
Hi,
By looking your diagram it's still the same as you described in your earlier mails. So it doesn't help at all. :)
1) Is your server something that exists and is used in everyday life or is it something that you're going to build?
2) Are your clients something that already exists and is used in everyday life?
3) Are you now trying to figure out how to plug in Django in "Adming module/PC with GUI block"?

Hi Guys!
I've been busy a bit, I'm back to thread with the high level architecture. Attached here is a diagram, just to understand what i meant.
Don't pay attention for object I use to describe modules or architecture components.
Now you will be able to understand what I mean by the server module, the admin module, and the client module of my architecture.
As you could see on the diagram, the admin module is installd on the server(where the server module is installed) and is destined to provide views to the GUI.
The clients receive and send data to the server.
When the admin make some actions, some clients are notifed, and when client send informations admin (GUi is notified).
Now two things come in my mind when I was thinking :
- First I could stay in the way I want the server to use HTTP for the admin side, and another protocol to communicate with client. In that way the Admin Module (Django) will alter and read data from data base. and the server module will alter and read data from database. Then each information retrievement will lead in reading database since informations could have been changed. You can that's really heavy.
- Second do all things in http. Mean that my server is just a web application undertanding HTTP (I will the use django for that). The server will serve request depending on the type of request, and each client will communicate with the server using HTTP. Then server will define pages/urls for admin (to be sent to the GUI), and pages/urls for clients.
By this way, the only relation between my modules will be the protocol (HTTP for the instance) and they could be implemented in what ever language we like. The sever will run asynchronously for admin and clients.
The admin will then be just an interface to wich convert data to the right display format for the GUI. And the GUI could be any type, and for the web interface type I will use DJANGO for my Admin module.
I will then also have to develop a http client for my client module.
Actuallu I'm going to take the second choice, since it lets all the charge for read and write database to the server, which could run and publish informations asynchronously(websocket could help here).
I precise that I'm not a web architect or designer, but i understand software architecture. I'm really a system and network engineer, with good developpement skill but not to much in web.
Look now my architecture diagram and tell me if what I'm describing in the second item fit. And give idea if you have, about libraiies and or framwork that could help going fast and easy.
I thing I will use django and green unicorn.
Thanks for your attention.2012/5/16 Alec Taylor <alec.taylor6@gmail.com>
Oh right, it's just Pyjamas.
Still, annoyed I didn't think to recommend it first!
