django 类视图

from django.urls import reverse_lazy
from django.views.generic import (
    TemplateView, ListView, DetailView,
    CreateView, UpdateView, DeleteView
)
from .models import MyModel

# 1) 仅渲染模板，不依赖模型
class HomePageView(TemplateView):
    template_name = "myapp/base.html"


# 2) 列表视图
class MyModelListView(ListView):
    model = MyModel
    template_name = "myapp/object_list.html"     # 指定模板
    context_object_name = "object_list"          # 在模板中使用的上下文变量
    paginate_by = 10                             # 如果需要分页

# 3) 详情视图
class MyModelDetailView(DetailView):
    model = MyModel
    template_name = "myapp/object_detail.html"
    context_object_name = "object"


# 4) 新建视图
class MyModelCreateView(CreateView):
    model = MyModel
    fields = ["title", "content"]               # 自动生成表单字段
    template_name = "myapp/object_form.html"
    success_url = reverse_lazy("myapp:list")     # 成功后跳转

# 5) 更新视图
class MyModelUpdateView(UpdateView):
    model = MyModel
    fields = ["title", "content"]
    template_name = "myapp/object_form.html"
    success_url = reverse_lazy("myapp:list")

# 6) 删除视图
class MyModelDeleteView(DeleteView):
    model = MyModel
    template_name = "myapp/object_confirm_delete.html"
    success_url = reverse_lazy("myapp:list")
