从UpdateView或Django中的ListView创建С对象的完整副本

from django.views.generic import UpdateView, ListView
from django.shortcuts import render
from django.urls import reverse_lazy
import copy

from .forms import YourForm
from .models import YourModel


class CopyObjectView(UpdateView):
    model = YourModel
    form_class = YourForm
    template_name = 'your_template.html'
    success_url = reverse_lazy('your_success_url')

    def get(self, request, *args, **kwargs):
        original_object = self.get_object()
        
        # 浅复制对象
        # copy_object = copy.copy(original_object)
        
        # 深复制对象
        copy_object = copy.deepcopy(original_object)
        
        # 可以为复制对象设置新的属性或值
        copy_object.id = None
        
        context = self.get_context_data(
            form=self.get_form(),
            original_object=original_object,
            copy_object=copy_object
        )
        return self.render_to_response(context)
