在Django前端删除多行 [英] Deleting multiple rows in Django frontend

问题描述

我将在django中添加多个删除（通过选择框）视图。

I am going to implment a multi delete (via select boxes) view in django.

我知道django.contrib.admin.actions中有一个视图，但是我不能将其移植到前端。

I know there's a view in django.contrib.admin.actions but I can't port this to frontend.

我应该将表单中的对象ID分配给我的删除视图，然后使用.delete（）？

Should I assign object id's in the form and POST these to my delete view and then use .delete() ?

我以前没有编程，Django是我开始编程冒险的框架。

I haven't been programming before, and Django is the framework I start my programming adventure.

我在寻找例子（对于Django视图+ html），但找不到任何。

I was looking for example (for Django view + html) but couldn't find any.

推荐答案

使用 modelformset 并手动呈现表单只需删除选项： https://docs.djangoproject.com/en/dev/topics/forms/formsets/#manually-rendered-can-dele te-and-can-order

替代解决方案：

使用 modelformset 创建一堆带有删除复选框，如下所示：

Using a modelformset to create a bunch of forms with a delete checkbox like this:

class YourModelForm(forms.ModelForm):
    id = fields.IntegerField(widget=widgets.HiddenInputField)
    delete = fields.BooleanField(required=False)

    def save(self, commit=False):
        if self.is_valid() and self.cleaned_data['delete']:
            self.instance.delete()             

    class Meta:
        model = YourModel
