Question

我试图冲破Django的以下法典,以说明其做些什么,并在必要时加以ed弄,但我可以清楚地说明其中几个职能正在做些什么,或者它们从哪里恢复。

是否测试——func,并且认为——func Django是特定的,还是这些建筑职能?

Conclusion: I m not sure how/why I overlooked the fact that these were simply being defined as arguments to the functions. I need to start paying better attention to details.

这里的Django功能I m试图打破/数字:

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

Answer 1

Django view.test_func is a function “theeck that theuserpass the given test”。

因此,你写了要求用户提供某种物品的职能,如果通过,请上。然后,你将这一功能通过到<条码>用户_passes_test上,并创设了一个指导器,在用户看到其意见之前,可以首先测试用户。

@user_passes_test
def test_intelligence(user):
    if is_intelligent:
        return True
    else:
        return False

@test_intelligence
def my_view(request):
    #this is the view you only want intelligent people to see
    pass

http://docs.python.org/fer/compound_stmts.html#Function"rel=“nofollow” <代码>wraps 是通过评分程序保存所包装功能(名称、动力等)的标记。位于in functools 。

Answer 2

>>> 用户_passes_test-rel> is a 。这一概念适用于一种观点(成为变式<代码>view_func)——它通过了一个具有<代码>User和回归代码/code>或False的功能。
