Question

我在基于类的视图中使用以下代码

from django.core.urlresolvers import reverse_lazy

url = reverse('url_name')

urls.py如下所示

from django.conf.urls import patterns, url

from myapp import views

urlpatterns = patterns('',
    url(r'^$', views.TestView.as_view(), name='url_name'),
)

这样做时我收到了弃用警告：

DeprecationWarning: Function-based generic views have been deprecated; use class-based views instead.
  DeprecationWarning

警告会出现在'django / views / generic / simple.py:8`

上

这是一个堆栈，看看有什么hapens：

-> return urlresolvers.reverse('url_name')
  /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/core/urlresolvers.py(476)reverse()
-> return iri_to_uri(resolver._reverse_with_prefix(view, prefix, *args, **kwargs))
  /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/core/urlresolvers.py(363)_reverse_with_prefix()
-> possibilities = self.reverse_dict.getlist(lookup_view)
  /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/core/urlresolvers.py(276)reverse_dict()
-> self._populate()
  /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/core/urlresolvers.py(265)_populate()
-> lookups.appendlist(pattern.callback, (bits, p_pattern, pattern.default_args))
  /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/core/urlresolvers.py(216)callback()
-> self._callback = get_callable(self._callback_str)
  /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/utils/functional.py(27)wrapper()
-> result = func(*args)
  /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/core/urlresolvers.py(92)get_callable()
-> lookup_view = getattr(import_module(mod_name), func_name)
  /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/utils/importlib.py(35)import_module()
-> __import__(name)
> /home/vagrant/.virtualenvs/wfp/lib/python2.5/site-packages/django/views/generic/simple.py(6)<module>()
-> import warnings

未来的做法是什么？我目前正在使用Django 1.4。

Answer 1

这只是Django功能的自动警告，如果您计划迁移到不支持此版本的较新Django版本，则不应使用该警告。

您可以查看弃用计划here

Answer 2

这只是一个猜测，但也许我正在以正确的方式做到这一点我只是可以忽略这个警告，因为我使用的函数不依赖于基于函数的视图，而只是它们在扩展的导入范围内urlresolvers模块。
