【问题描述】：

我在页面上有一个表单，可以将数据添加到数据库并显示在表格中

我需要添加一个按钮，该按钮将按 id 从数据库中删除特定行

index.html

<tbody>
                            % for expense_item in expense_items %
                            <tr>
                                <td> expense_item.username</td>
                                <td> expense_item.expense_name </td>
                                <td> expense_item.category </td>
                                <td> expense_item.cost zł</td>
                                <td> expense_item.date_added</td>
                                <td>BUTTON HERE</td>
                            </tr>
                            % endfor %
                        </tbody>

模型.py

class ExpenseInfo(models.Model):
     username = models.CharField(max_length=255, default='NoName')
     expense_name = models.CharField(max_length=20)
     category = models.CharField(max_length=20)
     cost = models.FloatField()
     budget_id = models.CharField(default='0123456789', max_length=10)
     date_added = models.DateField()
     user_expense = models.CharField(max_length=20)

Views.py

def add_item(request):
budget_id = request.user.last_name
name = request.POST['expense_name']
category = request.POST['category']
expense_cost = request.POST['cost']
expense_date = request.POST['expense_date']
try:
    ExpenseInfo.objects.create(username=request.user, expense_name=name, category=category, cost=expense_cost,
                               date_added=expense_date, user_expense=budget_id)
except ValueError or TypeError:
    print('No data.')
return HttpResponseRedirect('app')

【参考方案1】：

您可以在form 标签内添加一个按钮，form 标签在td 标签内，如下所示：

<tbody>
   % for expense_item in expense_items %
   <tr>
      <td> expense_item.username</td>
      <td> expense_item.expense_name </td>
      <td> expense_item.category </td>
      <td> expense_item.cost zł</td>
      <td> expense_item.date_added</td>
      <td>
         <form method="POST" action=% some url%>
            % csrf_token %
            <button type="submit">Button Here</button>
         </form>
      </td>
   </tr>
   % endfor %
</tbody>
