django - 如何通过 django admin 中的操作请求用户输入？

Question

在我的代码中，我正在编写一个用于分组的操作，我想询问用户他们希望每个组有多少人，然后用一个警告框进行响应，根据用户输入，您有 4 个组.我如何在 django admin 中执行此操作，我如何创建某种弹出窗口，询问他们想要加入一个组的人数？ (我试图通过一个 Action 来实现这一点)

管理.py:

 Def howmany (modeladmin, request, queryset):
      people = queryset.count()
      amount_per = [the number that the user inputs]
      Amount_of_groups = people/amount_per

Answer 1

admin.py 类似:

Class MyAdmin(admin.ModelAdmin):

    def howmany (modeladmin, request, queryset):
        people = queryset.count()
        amount_per = [the number that the user inputs]
        Amount_of_groups = people/amount_per

        if 'apply' in request.POST:
            form = AmountPerForm(request.POST)

            if form.is_valid():
                amount_per = form.cleaned_data['amount_per']
                self.message_user(request, u'You selected - %s' % amount_per)
            return HttpResponseRedirect(request.get_full_path())
        else:
            form = AmountPerForm()

        return render(request, 'admin/amount_per_form.html', {
            'items': queryset.order_by('pk'),
            'form': form,
            'title': u'Your title'
            })

文件“admin/amount_per_form.html”包含如下内容:

 {% extends 'admin/base_site.html' %}

 {% block content %}
 <form action="" method="post">
    {% csrf_token %}
    <input type="hidden" name="action" value="assign_new_manager" />
    {{ form }}
    <p>Apply for:</p>
    <ul>{{ items|unordered_list }}</ul>
    <input type="submit" name="apply" value="Apply" />
 </form>
 {% endblock %}
