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:

但在我的项目中，我有这个:
Uncaught TypeError: Cannot call method 'sayhello' of undefined

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:
ajapp.py 中添加一些打印语句看看它们是否被打印出来。 models.py和 views.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 :)
关于ajax - 达贾西。无法调用未定义的方法 '...'。再次，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13572826/
