Question

我已经使用Django 1.11.14，python 2.7和win 7建立了一个网站，可以让注册用户登录。但是，当我登录时，某些页面应该再次显示登录链接，而应该是注销链接。

主页

view.py

class LoanedFWsByUserListView(LoginRequiredMixin,generic.ListView, FormView):


model = XX
paginate_by = 10
template_name = 'FW_request.html'
def get(self, request):
    form = xx[![enter image description here][1]][1]Form()
    FW_list = FW.objects.all().order_by('approve_time').reverse()        
    return render_to_response(self.template_name, locals())

当我登录到主页时，它是正确的，但是当我单击“我的应用”之类的其他选项卡时，尽管我仍然处于登录状态，但它会在页面上显示登录名，应该在该位置注销

Answer 1

您应该使用render函数而不是public class ConfigureMvcOptions : IConfigureOptions<MvcOptions> { private readonly IUserRepository userRepository; public ConfigureMvcOptions(IUserRepository userRepository) { this.userRepository = userRepository; } public void Configure(MvcOptions options) { var policy = new AuthorizationPolicyBuilder() .RequireAuthenticatedUser() .Build(); options.Filters.Add(new RolesAuthorizationFilter(userRepository)); } }。该请求可以在模板中使用。

render_to_response

Answer 2

您错过了在此处使用基于类的视图的意义。如果有的话，应该很少定义get（或post）。在这种情况下，您只应定义get_context_data来添加FW_list，并让视图处理创建表单和呈现模板的过程。

def get_context_data(self, **kwargs):
    kwargs['FW_list'] = FW.objects.all().order_by('approve_time').reverse()        
    return super().get_context_data(**kwargs)

Django网页在应该注销时显示登录名
