我该如何满足 direct_to_template 的导入？

Question

我在一个最初是用Pinax 0.7做的项目中遇到了一个错误页面：

ImportError at /
No module named simple

它在urls.py的第3行出问题了，具体是：

from django.views.generic.simple import direct_to_template

我该如何更改导入的内容或者它使用的地方呢：

    urlpatterns = patterns('',
    url(r'^$', direct_to_template, {
        "template": "homepage.html",
    }, name="home"),

看起来我可以创建一个视图，使用render_to_response()来处理主页，但我想知道应该怎么解决这个问题，如果没有人告诉我更好的方法，我就先用这个办法。

Answer 1

除了基于类的视图 TemplateView，你还可以像这样使用 render 函数：

from django.shortcuts import render

urlpatterns = patterns("",
    url(r'^$', lambda request: render(request, 'homepage.html'), name="home"),
)

Answer 2

direct_to_template这个功能已经不再推荐使用了。在django 1.5版本中，建议你使用一种基于类的视图，叫做 TemplateView，你可以在 urls.py 文件中使用它。

from django.views.generic import TemplateView

urlpatterns = patterns('',
    url(r'^$', TemplateView.as_view(template_name='homepage.html'), name="home"),
)

关于如何迁移到1.4版本（这个功能在那时就不推荐了）的信息，可以在 这里 找到。
