<p>不,不能将请求传递给<code>user_passes_test</code>。要理解它为什么以及如何工作,只需转到<a href="https://github.com/django/django/blob/1.3.1/django/contrib/auth/decorators.py" rel="noreferrer">source</a>:</p>
<pre><code>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):
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
</code></pre>
<p>这是装饰器后面的代码。如您所见,传递给decorator的测试函数(在您的例子中,<code>lambda u: has_add_permission(u, "project")</code>)只传递了一个参数<code>request.user</code>。现在,当然可以编写自己的decorator(甚至直接复制并修改代码)来传递<code>request</code>本身,但是不能使用默认的<code>user_passes_test</code>实现。</p>
