进展如何？我正在学习用django编程。目前，我正在构建一个简单的应用程序，该应用程序利用表单更新引用的表。现在，我尝试在表的每一行中添加一个删除按钮，但是，除了我尝试了很多解决方案之外，我没有找到一个正常工作的解决方案。在我的代码下面：网址from django.urls import pathfrom app import viewsapp_name = 'main'urlpatterns = [ path('', views.homepage, name='homepage'), path('delete_item/<int:pk>', views.delete_item, name="delete_item"),]形式from django import formsfrom .models import Incomeclass IncomeModelForm(forms.ModelForm): class Meta: model = Income fields = "__all__"表import django_tables2 as tablesfrom django_tables2.utils import Afrom .models import Incomeclass PersonTable(tables.Table): delete = tables.LinkColumn('main:delete_item', args=[A('delete-id')], attrs={'a': {'class': 'btn'}}) class Meta: model = Income template_name = "django_tables2/bootstrap.html"视图from django.shortcuts import renderfrom django.http import HttpResponsefrom django.views.generic import ListViewfrom .models import Incomefrom .tables import PersonTablefrom .forms import IncomeModelFormdef homepage(request): table = PersonTable(Income.objects.all()) if request.method == 'POST': form = IncomeModelForm(request.POST) if form.is_valid(): print("Il form è valido") new_input = form.save() else : form = IncomeModelForm() context= {"form": form, "table":table } return render(request, "app/base.html", context)def delete_item(request, pk): Income.objects.filter(id=pk).delete() items = Income.objects.all() context = { 'items': items } return render(request, 'app/base.html', context)断续器{% load static %}{% load render_table from django_tables2 %}<!doctype html><html> <head> <!-- Required meta tags --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">我的表取消了“删除”列，但没有 buttoms，只有一个“-”。为什么？我的错误在哪里？

在表中显示记录时，需要使用“删除表单”按钮添加额外的表数据。例如：
<table>
{% for item in items%}
<tr>
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>
<form method="delete">
<input type="hidden" value="{{item.id}}" name="delete-id">
<input type="Submit">Delete</button>
</form>
</td>
</tr>
{% endfor}
</table>
现在，在 views.py 添加删除部分并删除记录：
if request.method == 'DELETE':
Person.objects.get(pk=request.DELETE['delete-id']).delete()
您正在使用django_tables2，您只需将此代码添加到 tables.py
from django_tables2.utils import A # alias for Accessor
class PersonTable(tables.Table):
delete = tables.LinkColumn('main:delete_item', args=[A('delete-id')], attrs={
'a': {'class': 'btn'}
})
