Question

以下视图按预期工作

class BrandEditView(PermissionRequiredMixin ,generic.UpdateView):
    permission_required = 'change_brand'

    template_name = 'brand_update_form.pug'
    model = Brand
    fields = ['name']

    def get_object(self, queryset=None):
        print(self.request.user)
        self.object = Brand.objects.get(id=self.kwargs['pk'])
        obj = Brand.objects.get(id=self.kwargs['pk'])
        return obj

表单提交后，如何返回相同的视图（使用相同的对象），但是使用上下文，如消息：＆＃34;品牌编辑成功＆＃34; /＆＃34;您可以＆＃39;做那个＆＃34;？我找到了一种重定向到相同视图的方法，但没有使用上下文。

在基于类的视图中使用消息框架我们使用SuccessMessageMixin

所以请将您的观点更新为：

#!/bin/bash

function add_user () {
    while true; do
        echo -e "\nInsert a name for the Squid3 user (0=exit): \c"
        read utente
        case "$utente" in
            0)
                echo -e "\nGoodbye $USER!\n"
                exit 0
            ;;
            *\ *)
                echo -e "\nYou can't use spaces in the name!"
                sleep 2
                continue
            ;;
            *)
                break
            ;;
        esac
    done
    if [ ! -e '/etc/squid3/.passwd' ]; then
        sudo htpasswd -c /etc/squid3/.passwd $utente
    else
        sudo htpasswd /etc/squid3/.passwd $utente
    fi
}

function installer () {
    sudo apt-get install squid3 apache2-utils -y
    sudo bash -c "echo 'here
you
must
paste
your
configuration
file' > /etc/squid3/squid.conf"
    sudo service squid3 restart
}

if ! [ "$(sudo which squid3)" ]; then
    installer
    add_user
else
    add_user
fi

并在基本模板或任何模板中添加：

from django.contrib.messages.views import SuccessMessageMixin
class BrandEditView(SuccessMessageMixin, PermissionRequiredMixin ,generic.UpdateView):
    permission_required = 'change_brand'
    success_url = reverse_lazy('your redirect url')
    template_name = 'brand_update_form.pug'
    model = Brand
    fields = ['name']
    success_message = "created successfully!"
    def get_object(self, queryset=None):
        print(self.request.user)
        self.object = Brand.objects.get(id=self.kwargs['pk'])
        obj = Brand.objects.get(id=self.kwargs['pk'])
        return obj

Django：如何从UpdateView（CBV）返回上下文？
