django - Django新闻通讯应用

Question

django是否有任何新闻通讯应用程序，允许用户订阅/取消订阅新闻通讯？我想要一个易于使用且可通过Django管理员进行管理的应用。

也许吧，也许不是。拥有在时事通讯（无论如何想象）与订阅者（用户或用户的外键或firstName / lastName / emailAddress / password）之间具有多对多关联的应用程序并不难。

您的模型将如下所示：

from django.db import models
from django.contrib.auth.models import User

class Subscriber(models.Model):
    user = models.ForeignKey(User)
    email = models.EmailField()

    def __unicode__(self):
        return "User %s" % (self.user.username, )

    @models.permalink
    def get_absolute_url(self):
        return ('subscriber', None, {'object_id' : self.id})

    class Meta:
        ordering = [ "id" ]

class Newsletter(models.Model):
    name = models.CharField(max_length=80)
    subscribers = models.ManyToManyField('Subscriber')
    # .... Other stuff

    def __unicode__(self):
        return "Newsletter %s" % (self.name, )

    @models.permalink
    def get_absolute_url(self):
        return ('newsletter', None, {'object_id' : self.id})

    class Meta:
        ordering = [ "id" ]

您的urls.py将如下所示：

from django.conf.urls.defaults import *
from django.views.generic.simple import direct_to_template

urlpatterns = patterns('',
    url(r'^subscriber/(?P<object_id>\d+)/$', views.subscriberview, name='subscriber_view'),
    url(r'^newsletter/(?P<object_id>\d+)/$'', views.newsletterview,name='newsletter_view'),
    url(r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': MEDIA_ROOT}),
)

这足以使您前进吗？
