问题
I am writing a simple Django application and wish to add ajax paging using Dajax / Dajaxice. I have started by trying to implement the simple paging example from the Dajax website (http://dajaxproject.com/pagination/) - but haven't managed to get it working. Whenever I press the "next" button I get the following js error:
Uncaught TypeError: Cannot call method 'pagination' of undefined
My Django project is called "DoSomething" - and it contains a single app called "core".
I have followed all of the instructions to install Dajaxice here: https://github.com/jorgebastida/django-dajaxice/wiki/installation
I have an python file in the "core" directory called "ajax.py" which contains the following code:
from views import get_pagination_page
from dajax.core.Dajax import Dajax
from django.template.loader import render_to_string
from dajaxice.decorators import dajaxice_register
from django.utils import simplejson
@dajaxice_register
def pagination(request, p):
try:
page = int(p)
except:
page = 1
items = get_pagination_page(page)
render = render_to_string('posts_paginator.html', { 'items': items })
dajax = Dajax()
dajax.assign('#pagination','innerHTML',render)
return dajax.json()
My views.py file contains the following method:
def index(request):
posts = Post.objects.order_by('id').reverse()
items = get_pagination_page(1)
return render_to_response('index.html', locals(), context_instance=RequestContext(request))
def get_pagination_page(page=1):
from django.core.paginator import Paginator, InvalidPage, EmptyPage
from django.template.loader import render_to_string
items = Post.objects.order_by('id').reverse()
paginator = Paginator(items, 10)
try:
page = int(page)
except ValueError:
page = 1
try:
items = paginator.page(page)
except (EmptyPage, InvalidPage):
items = paginator.page(paginator.num_pages)
return items
My index template contains the following:
<div id="pagination">
{% include "posts_paginator.html" %}
</div>
My posts_paginator.html template contains the following link, to trigger the pagination method:
{% for i in items.object_list %}
{{ i }}<br>
{% endfor %}
{% if items.has_next %}
<a href="#" onclick="Dajaxice.core.pagination(Dajax.process,{'p':{{ items.next_page_number }}})">next</a>
{% endif %}
My question is, within the onClick value, how should I be referencing the pagination method (from my ajax.py file). I can't find anything to explain this - and I've tried every combination of project name/app name that I can think of!
THANKS! :)
回答1:
At least in my case I have to append the Project name as well as the app_label.
Dajaxice.MyProject.core.my_dajax_method(Dajax.process, {'form' : data});
