I believe I understand what you are saying. But I was hoping that
Django offered the javascript framework that allowed multi-windows. To
get what I want I will have to use a javascript framework - I
understand. But that said, I have been researching several of the
javascript frameworks and they do in fact allow new tabs (using
chrome). Example: google mail will allow multi-pages (actually tabs) of
contacts just with multi clicks on the GMAIL dropdown. But that wasn't
what I was hoping for - I want individual windows/forms that I can
resize, move, Max, Min, etc... So far the only thing I have found was
the electron app I spoke about earlier. The electron framework allowed
windows that can be resized, moved about the screen, and closed. I am
still researching but so far only Electron. BTW the Electron is really
a desktop app using web tools (css, html, javascript, and nodejs). I'm
guessing (mostly from your emails) that there are javascript frameworks
that will allow what I looking for - I just haven't found it YET!

No John,
I don't think you understand what we are saying :-)
Like I said earlier - Django is a HTML framework - like ALL HTML
framework, it renders the pages you are seeing on the backend and
presents the information to the user. That is per design in the HTML
world. You click on a link and then the server renders a new page and
so on. There is no way to add "windows" in any other way than to open
a new browser. That is the way HTML works.
If you want to add a fancy single page application (which is what you
are suggesting) then the only way to do so is to use a Javascript
framework of some kind. What that does is to add the ability to do
windows and the like - just in the way you want to do it - and that is
still within the "web UI wold". If you look at things like the google
cloud engine interface or gmail or the amazon AWS interface, that is
all done on the web, with a web UI. However all of those pages REQUIRE
javascript to function.
So it is often requested and I am currently working on a single page
application that uses django for the backend, but HTML cannot render
the single page application - that is done in a javascript framework.
So web UI is completely on par with a desktop application but it
requires more components that you are willing to use :-)

The reason I wanted Django was to insure that the data is valid
(using python). When they enter the data and the submit button
is clicked I want to be able to modify the response using python.
So what I'm hearing from the list - is that in general - people
are not using the Django template system. Is that right?
I have been doing a little research and have discovered a couple
of javascript tools that allow multi -
windows/forms/dialogs/frames. But then - like you said - I'm
replacing the Django template system.
It seems that web UI is still not up to the desktop abilities.
That's not good. BTW I was looking at Electron and discovered
that it can easily match the desktop multi-window and it's using
web tech. So I'm guessing it is possible but not often requested.

Hi,
I think you are not thinking this completely through correctly.
Django is a framework used to generate HTML pages. HTML pages
render one page at a time in one webbrowser window. That is the
way HTML works.
You can via javascript do some funky things, like Single page
applications - but then most of the templating engine in django
isn't used. You could create templates on the backend and send
them via ajax to the frontend but that is mainly used for
rendering partial pages and not for complete pages. Also, it
would be really cumbersome to write the code.
If you already have a REST backend, why do you need django at
all? Django isn't the best framework for getting information from
a REST API and then publishing the information. You really should
be looking into running a single page application in that case...
Django can be used to create a REST backend for the single page
application however.

I have the backend covered with REST. When I try to google
hybrid google comes up with hybrid mobile apps. I did find
fragment.js but I don't see any type of real information on
how to use it. I did find some info on javascript and
multi-windows but here again it looks like it wants to
replace the template system that Django uses.
It just seems to me that this issue must have come up in the
past. There must be a solution provided by Django without
replacing parts of the Django framework????

Hi.
Yes and no. Usually you do SPA, a single page application,
that just talks to backend, Django in this case, using some
means. REST api and JSON data is quite common.
So basically you need only one template that fires up rest
of your interface.
There are though alternative approaches like using hybrid of
JS library to request HTML fragments and render them using
JS. Fragments then are generated using templates.

But doesn't Django provide the template system? Do you
replace the template system with DoyuoToolkit?

Hi,
This actually doesn't have anything to do with
Django, but frontend. Basically you need to pick
some Javascript UI framework that supports features
you're after.
Personally I've only used Dojotoolkit (free, nicely
licensed) and ExtJS (commercial).

Hi,
I have a desktop CRUD application that allows
the same form to be opened many times. Example:
I can open a customer's (A) record in one
window/form and then from the first window/form
(customer A's) open a second or third window to
process customer B or customer C etc... all
without closing any of the windows/forms. IOW I
can have many windows open at the same time all
using the same form with different customer records.
How can I do this with Django? I would like to
replace the desktop app with a web app using Django.
