<p>我发现编辑<code>user_passes_test</code>使修饰函数在<code>request</code>上操作而不是<code>request.user</code>并不太困难。我在<a href="http://blog.jdotjdot.com/2014/06/decorator-decorator/" rel="nofollow">this blog post</a>中有一个关于视图装饰器装饰器的简短版本,但是对于子孙后代,这里是我的完整编辑代码:</p>
<pre><code>def request_passes_test(test_func, login_url=None, redirect_field_name=REDIRECT_FIELD_NAME):
"""
Decorator for views that checks that the request passes the given test,
redirecting to the log-in page if necessary. The test should be a callable
that takes the request object and returns True if the request passes.
"""
def decorator(view_func):
@wraps(view_func, assigned=available_attrs(view_func))
def _wrapped_view(request, *args, **kwargs):
if test_func(request):
return view_func(request, *args, **kwargs)
path = request.build_absolute_uri()
# urlparse chokes on lazy objects in Python 3, force to str
resolved_login_url = force_str(
resolve_url(login_url or settings.LOGIN_URL))
# If the login url is the same scheme and net location then just
# use the path as the "next" url.
login_scheme, login_netloc = urlparse(resolved_login_url)[:2]
current_scheme, current_netloc = urlparse(path)[:2]
if ((not login_scheme or login_scheme == current_scheme) and
(not login_netloc or login_netloc == current_netloc)):
path = request.get_full_path()
from django.contrib.auth.views import redirect_to_login
return redirect_to_login(
path, resolved_login_url, redirect_field_name)
return _wrapped_view
return decorator
</code></pre>
<p>我唯一做的就是把<code>if test_func(request.user):</code>改成<code>if test_func(request):</code>。</p>
