使用Django管理员操作与中间页面的问题 [英] Problem using Django admin Actions with intermediate pages

问题描述

我通过admin.py添加了一个管理操作send_EMAIL。我希望管理员对所选用户使用 send_EMAIL 操作时，应该显示所有选定用户的中间页面，并要求确认。在我的情况下请求确认，但是当我点击发送电子邮件按钮没有任何反应，我已经返回到change_list视图，没有send_EMAIL操作被调用。

I added an admin action send_EMAIL through admin.py.I want when admin uses send_EMAIL action for selected users it should show an intermediate page with all selected users and ask for confirmation.In my case it ask for confirmation but when I click on "send Email" button nothing happens and i got returned to change_list view without send_EMAIL action got called.

Admin.py

class MyUserAdmin(UserAdmin):
    list_display = ['username', 'email', 'first_name', 'last_name', 'is_active', staff]
    list_filter = ['groups', 'is_staff', 'is_superuser', 'is_active']
    actions = ['send_EMAIL']


    def send_EMAIL(self, request, queryset):
        from django.core.mail import send_mail
        if 'apply' in request.POST:
            for i in queryset:
                if i.email:
                    send_mail('Subject here', 'Here is the message.', '[e-mail]',[i.email], fail_silently=False)
                else:
            self.message_user(request, "Mail sent successfully ")
        else:
            from django.http import HttpResponse
            from django.template import RequestContext, loader
            t = loader.get_template('admin/send_mail.html')
            c = RequestContext(request, {'articles': queryset})
            return HttpResponse(t.render(c),)



admin.site.unregister(User)
admin.site.register(User, MyUserAdmin)

模板/send_mail.html

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

{% block content %}


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

    <p>The mail will be send to following users:</p>

    <ul>{{ articles|unordered_list }}</ul>

    <input type="hidden" name="action" value="send_EMAIL" />
    <input type="submit" name="apply" value="Send Email" />
</form>

{% endblock %}

我找到了一个简单的方法。它对我有用...我希望它有助于：

I found an easy way to do it. It worked for me... I hope it helps:

您需要做的是将选定的项目传递到确认页面，并将它们包含在表单中以及包含< input type =hiddenname =actionvalue =admin_action/> ，以便django管理员知道它仍然应该调用 admin action 。 post 只是要知道是处理查询集还是呈现确认页面。

What you need to do is to "pass" the selected items to the confirmation page and include them in the form as well as including the <input type="hidden" name="action" value="admin_action" /> so that django admin knows that it should still call an admin action. The post is just to know whether to process the query set or render the confirmation page.

# Write your admin action.
# IMPORTANT: Note the context passed to TemplateResponse

from django.contrib.admin import helpers
from django.template.response import TemplateResponse

class MyModelAdmin(admin.ModelAdmin):
    def admin_action(self, request, queryset):
        if request.POST.get('post'):
            # process the queryset here
        else:
            context = {
                'title': _("Are you sure?"),
                'queryset': queryset,
                'action_checkbox_name': helpers.ACTION_CHECKBOX_NAME,
            }
            return TemplateResponse(request, 'path/to/template.html',
                context, current_app=self.admin_site.name)

# The template
{% extends "admin/base_site.html" %}
{% load i18n l10n %}

{% block content %}
<form action="" method="post">{% csrf_token %}
    <p>The following videos will be accepted:</p>

    <ul>{{ queryset|unordered_list }}</ul>

    <div>
    {% for obj in queryset %}
    <input type="hidden" name="{{ action_checkbox_name }}" value="{{ obj.pk|unlocalize }}" />
    {% endfor %}
    <input type="hidden" name="action" value="admin_action" />
    <input type="hidden" name="post" value="yes" />
    <input type="submit" value="{% trans "Yes, I'm sure" %}" />
    </div>
</form>
{% endblock %}
