I'm working through the random machine example, but I'm having trouble. I've installed Dajax and Da开发者_JS百科jaxice according to these two pages: Dajax and Dajaxice. My ajax.py file looks like this:
import random
from dajax.core import Dajax
from dajaxice.decorators import dajaxice_register
@dajaxice_register
def randomize(request):
dajax = Dajax()
dajax.assign('#result','value',random.randint(1, 10))
return dajax.json()
Here's my views.py:
from django.shortcuts import render_to_response
from django.template import RequestContext
def dajax(request):
return render_to_response( 'dajax.html', context_instance=RequestContext(request) )
Here's my urls.py:
from django.conf.urls.defaults import patterns, include, url
from dajaxice.core import dajaxice_autodiscover
from dajaxice import urls
from django.conf import settings
from Dajax.myapp.views import dajax
dajaxice_autodiscover()
urlpatterns = patterns('',
(r'^%s/' % (settings.DAJAXICE_MEDIA_PREFIX), include('dajaxice.urls')),
(r'^dajax/$', dajax),
)
My html form tag looks like this:
<form>
<input type="text" name="result" value="" id="result">
<input type="button" name="rand" value="Let's Rand!" id="rand" onclick="Dajaxice.myapp.randomize(Dajax.process); return false;">
</form>
Here's what my head tag looks like:
<head>
<title>My base template</title>
{% dajaxice_js_import %}
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js" type="text/javascript" charset="UTF-8"></script>
<script src="{{ STATIC_URL }}js/jquery.dajax.core.js" type="text/javascript" charset="UTF-8"></script>
</head>
I added the following to my init.py file in my project dir:
from myapp.ajax import randomize
Also of note, my Django app's name is myapp.
On my page, when I click on Let's Rand!, the page goes to http://localhost:8000/dajax/?result=2, and no value shows up in the text input box. I checked the console in Chromium and there aren't any errors.
Did I incorrectly install either Dajax or Dajaxice, or is there something wrong with my code above?
My guess is that because I'm using jQuery instead of Prototype, there's something different I need to do.
Thanks for your help!
You need a return false; in your onClick handler after the call to Dajax.
put this in your views.py :
from dajaxice.core import dajaxice_autodiscover
dajaxice_autodiscover()
You need to make sure that the app you are trying to import the ajak.py file from is in your INSTALLED_APPS in settings.py.
See the source for autodiscover:
