django：选择多行时创建表格形式 [英] django : create table form when selecting multiple rows

问题描述

我需要使用Django创建一个非常简单的表单，但似乎无法为其找到合适的工具，也许是因为我想要的词汇缺乏：

I need to create a pretty straight forward form with Django but seems to be unable to find the proper tool for it, maybe because of the lack of vocabulary on what I want :

我有一个n行的表（n个变化），每一行代表一个数据库对象。我想在每行的左侧放置一个复选框，以便能够选择多行并在顶部的多选小部件中应用一个动作。

I have a table of n rows (n varies), each row represents a database object. I want to put a checkbox in front left of each row to be able to select multiple rows and apply an action placed in a multiplechoice widget at the top.

使用序列集序列化一个deleteview，但是无论如何我都不知道如何添加额外的操作（除delete之外）。

I thought about "serialize" a deleteview with formset but anyway I don't know how to add extra actions (apart from delete).

任何关于采取方向的有价值的信息都将受到欢迎，谢谢。

Any valuable information on direction to take would be welcome, thanks.

推荐答案

您可以尝试使用 Django表2 。像这样尝试：

You can try with Django Tables 2. Try like this:

import django_tables2 as tables


class YourTable(tables.Table):
    selection = tables.CheckBoxColumn(accessor='pk')  # Override here to show checkbox 
    class Meta:
        model = YourModel
        template_name = 'django_tables2/bootstrap.html'

使用表在视图中：

Use table in View:

def some_view(request):
    if request.method == "GET":
        table = YourTable(YourModel.objects.all())
        return render(request, 'template.html', context={'table': table})

模板

Template

<form method="post">
    {% csrf_token %}

    <select name="action_options">
        <option value="delete">Delete</option>
        <option value="hard_delete">Hard Delete</option>
    </select> 

    {% load render_table from django_tables2 %}  // loading template tag
    {% render_table table %}  // catching context as table from view

    <input type="submit" class="btn btn-primary" value="Delete">
</form>

更新视图以处理过帐请求

Update View to Handle Post Request

def some_view(request):
    ...
    if request.method == "POST":
        pks = request.POST.getlist("selection")  # handle selection from table
        action = request.POST.get('action_options')
        selected_objects = YourModel.objects.filter(pk__in=pks)
        if action == 'delete':
            selected_objects.delete()
        # Rest of your Logic
