如何显示外键子项的Django Admin更改列表视图？
|
我正在使用“广告系列”>“类别”>“帐户”的模型层次结构的应用程序。理想情况下，我希望用户能够单击广告系列管理员列表视图中的链接，并转到\“ / admin / myapp / campaign / 2 / accounts / \”这样的网址，它将显示django管理员视图具有所有方便的ChangeList便利设施，但经过过滤后仅显示指定广告系列中类别中的帐户（即Account.object.filter（category_campaign_id = 2））。 （请注意，类别本身很高兴能够在此帐户列表视图中成为“过滤器”）。
我似乎找不到任何模仿这种在许多其他框架中很常见的模仿“项-键-外键-子项列表”方法的方法的参考。
可能吗？ Django范例中是否有“更好”的方法？
谢谢你的帮助！

# models.py from django.db import models class Campaign(models.Model): name = models.CharField(max_length=20) def __unicode__(self): return unicode(self.name) class Category(models.Model): campaign = models.ForeignKey(Campaign) name = models.CharField(max_length=20) def __unicode__(self): return unicode(self.name) class Account(models.Model): category = models.ForeignKey(Category) name = models.CharField(max_length=20) def __unicode__(self): return unicode(self.name) # admin.py from django.contrib import admin from models import Campaign, Category, Account class CampaignAdmin(admin.ModelAdmin): list_display = (\'name\', \'related_accounts\', ) def related_accounts(self, obj): from django.core import urlresolvers url = urlresolvers.reverse(\"admin:<yourapp>_account_changelist\") lookup = u\"category__campaign__exact\" text = u\"View Accounts\" return u\"<a href=\'%s?%s=%d\'>%s</a>\" % (url, lookup, obj.pk, text) related_accounts.allow_tags = True admin.site.register(Campaign, CampaignAdmin) admin.site.register(Category) class AccountAdmin(admin.ModelAdmin): list_display = (\'category\', \'name\') list_filter = (\'category__campaign\',) admin.site.register(Account, AccountAdmin)篮肥炼皖
假设类别是Campaign-Model上的一个字段，则可以将以下方法添加到CampaignAdmin中：def account_link(self, obj): return \'<a href=\"/admin/yourproject/account/?category__id__exact=%s\">Accounts</a>\' % (obj.category.id) account_link.allow_tags = True不过，这取决于您的数据模型。 如果要创建适合您需要的经过过滤的永久性change_list视图，可以查看以下文章：http://lincolnloop.com/blog/2011/jan/11/custom-filters-django-admin/蔬谢窗港
或来做到这一点：class AccountAdmin(ModelAdmin): model = Account list_display = (\'pk\', \'campaign_changelist\') # ... def queryset(self, request): self._get_params = request.GET return super(AccountAdmin, self).queryset(request) def campaign_changelist(self, obj): url = reverse(\'admin:yourapp_account_changelist\') querystring = self._get_params.copy() querystring[\'campaign__id__exact\'] = obj.campaign.pk return u\'<a href=\"{0}?{1}\">{2}</a>\'.format( url, querystring.urlencode(), obj.campaign) campaign_changelist.allow_tags = True澳绍能
