You can always have some field that keep when the chat was
started (in the session), and redisplay everything since
that time.

Then what would be the good / best method to update only
the chat content ?
(I have 2 ideas but they don't seems very Django'ic)

2.
For now, I update the content every XX ms with a
periodic request client
side.
Would it be possible / preferable to have a push from
server when new
data comes or is there a better way to update this kind
of content ?


Trying to hack django to get server push would be hell (look
into tornado). If you really need server push, you may need
to look into other technologies, like nodejs.

Using the periodic request client-side is what is mostly done.


Hope this helps.

1.
My question was not clear enough,
Let's admit i have this template page :

/{% for elem in data %}//
////
//{{ elem.datetime }}//
//{{ elem.name 
}} ://
//{{ elem.text }}//
////
//{% endfor %}//
//Text : /

and this view.py :

/def getchat(request)://
//template = loader.get_template('chat.html')//
//context  = RequestContext(request, { 'data': lines
})//# lines is an array with lines
//response = {'html' : template.render(context)}//
//return HttpResponse(json.dumps(response),
mimetype='application/json')/

and this javascript :

/function getchat()//
//{ //
//$.post('/getchat')//.done(function(data, textStatus,
jqXHR) //
//{//
//$("#chat").html(data["html"])//
//})//
//}

/Then whenever I call getchat() in javascript, the chat is
reloaded with all the old lines, this point is ok, but
 field is reseted too, which mean that if user was
typing, the content is erased.
I would say the solution is to create a second function in
view /getchatcontent/ that will send only the content so I do
not
update the whole thing. Do you think it is the right way ?

Thank you for your answer



There is nothing more in chat.html
there is a base.html template that contains

///
//{% load staticfiles %}//






//post//
///


appchat.js


/$(document).ready(function()//
//{//
//$("#addline").click(function()//
//{//
//addline($("#chatname")[0].value,
$("#chatinput")[0].value);//
//$("#chatinput")[0].value = "" //
//})//
//setInterval(function() { getchat() }, 1000);//
//})//
//
//function addline(name, text)//
//{//
//$.post('/addline', {"name":name, "text":text})//
//.done(function() //{//})//
//}//
//
//function getchat()//
//{ //
//   $.post('/getchat')/
/
//.done(function(data, textStatus, jqXHR) //
//{//
   $("#chat").html(data["html"])//
//})//
//}/


Now you have everything, does this seems the right way to do what
I want to achieve with django or is there a better way ?

html templates and dynamic loading

2013-08-22 Thread Bastien Amiel 

Hi list,

I'm testing Django for a few days now and I have 2 questions.

I created for my tests a simple chat integrated in a base page (one 
template for the main page, and one for the chat).


I need to update the chat when an event come but :

1.
If I update my chat sub page, inputs are reset (seems logic since html 
is recreated).

Then what would be the good / best method to update only the chat content ?
(I have 2 ideas but they don't seems very Django'ic)

2.
For now, I update the content every XX ms with a periodic request client 
side.
Would it be possible / preferable to have a push from server when new 
data comes or is there a better way to update this kind of content ?
