我试图在Django中分解以下代码，以确定它在做什么，并在必要时对其进行编辑，但我不能很好地理解这些函数中的一些在做什么或它们来自何处。在
test-func和view-func-Django是特定的还是这些内置的python函数？在
结论：
我不知道我是如何/为什么忽略了这一事实，即它们只是被定义为函数的参数。我需要开始注意细节。在
下面是我要分解的Django函数：def user_passes_test(test_func, login_url=None, redirect_field_name=REDIRECT_FIELD_NAME):
"""
Decorator for views that checks that the user passes the given test,
redirecting to the log-in page if necessary. The test should be a callable
that takes the user object and returns True if the user passes.
"""
def decorator(view_func):
@wraps(view_func, assigned=available_attrs(view_func))
def _wrapped_view(request, *args, **kwargs):
print test_func
if test_func(request.user):
return view_func(request, *args, **kwargs)
path = request.build_absolute_uri()
# 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.urlparse(login_url or
settings.LOGIN_URL)[:2]
current_scheme, current_netloc = urlparse.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, login_url, redirect_field_name)
return _wrapped_view
return decorator
