views.py

Question

我有一个使用django的登录系统，我希望能够在包含导航的基本模板中显示属于它的登录用户和组酒吧。

直到现在，我可以返回用户名和组，并在控制台中打印出来。并在模板中显示用户名，但不包含组

views.py

def login_request(request):
    if request.method == "POST":
        username = request.POST['lognName']
        password = request.POST['lognCode']
        user = authenticate(username = username,password = password)
        if user.is_authenticated:
            print("user is authenticated", {username})
        else:
            print("user is NOT authenticated", {username})
        currentU = User.objects.filter(username=username).first()
        currentID = currentU.id
        print('current user is : ',currentID)
        groupName=User.objects.all().get(pk=currentID).groups.get().name
        print('set done ')
        print('the Groups Name {0}'.format(groupName))
        if user is not None:
            login(request,user)
            messages.info(request,f"You are now logged in as {username}")
            return redirect("create")
        else:
            messages.error(request,"invalid username or password")
            print("invalid username or password")

    return render(request,'login.html')

base.html

<!DOCTYPE html>

             </th>
    </ul>

Answer 1

您可以看到表格official documents，Django的内置string reportName = "TestReport"; string displayName = reportName; bool isDomainAuthentication = false; var reportParameters = new List<ReportParameter>(); reportParameters.AddRange((List<ReportParameter>)Session["ReportParameters"]); string ReportServerURL = "http://DESKTOP38/ReportServer_SQLEXPRESS"; reportViewer1.ServerReport.ReportServerUrl = new Uri(ReportServerURL); reportViewer1.ServerReport.ReportPath = "FolderName" + reportName; reportViewer1.ServerReport.DisplayName = displayName; reportViewer1.ShowPrintButton = true; reportViewer1.ShowToolBar = true; reportViewer1.ShowCredentialPrompts = false; if (!isDomainAuthentication) { string userId = "DESKTOP38"; //Username string password = "test"; string domain = ReportServerURL; IReportServerCredentials reportCredentials = new ReportServerCredentials(userId, password, domain); reportViewer1.ServerReport.ReportServerCredentials = reportCredentials; } if (reportParameters != null) { reportViewer1.ServerReport.SetParameters(reportParameters); } this.reportViewer1.ServerReport.Refresh();模型与User模型具有ManyToMany关系。您可以按Group访问用户组，但是由于可能有一个用户分配了多个组，因此您需要使用user.groups循环类型的表达式来显示它。

您可以使用此

{{user.groups.all.0.name}}

如何在Django中返回并在模板上显示用户名和组
