我一直在尝试使用 dajaxice 创建一个最简单的应用程序。
我在这里阅读了有关此问题的所有主题,不仅在这里,多次重写所有代码,但仍然看不到问题所在。
最有趣的是,这些例子(几乎所有)都有效:
https://github.com/jorgebastida/django-dajaxice/downloads dajaxice-examples.tar.gz

但在我的项目中,我有这个:

Uncaught TypeError: Cannot call method 'sayhello' of undefined 

我的工具:
  • window 7 64
  • python-2.7.3
  • Django-1.4.2
  • django-dajaxice-0.2

  • 项目结构:
    BlocalProject/
    templates/
    template_1.html
    manage.py
    BlocalProject/
    ajapp/
    __init__.py
    ajview.py
    __init__.py
    settings.py
    urls.py
    views.py
    wsgi.py

    网址.py:
    from django.conf.urls.defaults import *
    import settings
    from dajaxice.core import dajaxice_autodiscover
    dajaxice_autodiscover()


    urlpatterns = patterns('',
    (r'^%s/' % (settings.DAJAXICE_MEDIA_PREFIX), include('dajaxice.urls')),
    (r'^$', 'BlocalProject.views.start_page'),
    )

    View .py:
    from django.shortcuts import render

    def start_page(request):
    return render(request,'template_1.html')

    ajapp.py:
    from django.utils import simplejson
    from dajaxice.core import dajaxice_functions


    def sayhello(request):
    return simplejson.dumps({'message': 'Trololo!'})

    dajaxice_functions.register(sayhello)

    模板_1.html:
    {% load dajaxice_templatetags %}
    <html>
    {% dajaxice_js_import %}
    <script>
    function alertMessage(data){
    alert(data.message);
    return false;
    }
    </script>

    <body>
    Some text
    <input type="button" value="Get!" onclick="Dajaxice.ajapp.sayhello(alertMessage);" />
    </body>

    最佳答案

    这可能为时已晚,但...

    恕我直言,dajaxice_autodiscover()实际上并没有得到你的方法。我记得另一个 ajax lib 也有类似的问题,我通过在 models.py 中添加导入解决了这个问题。 (或 views.py ),在应用程序启动时导入。 example你提到在 simple/views.py 中有一个导入:

    # Create your views here.
    from django.shortcuts import render

    # THIS ONE!
    from dajaxice.core import dajaxice_functions
    # ---------


    def index(request):

    return render(request, 'simple/index.html')

    看起来它正在初始化东西。我的方法是:
  • 在您的 ajapp.py 中添加一些打印语句看看它们是否被打印出来。
  • 创建空 models.pyviews.py在您的 BlocalProject.ajapp (django 是否仍然使用 models.py 将模块验证为 django 应用程序?)

  • 如果您的打印语句没有被触发,那么您需要找出原因。正如我所提到的,它可能就像在模型中导入 ajax 模块一样简单 :)
