Question

我的一个模板中有django_tables2的django数据表。其中一列用于保存指向不同页面的链接。我对SO的问题一直有很多疑问，但似乎没有任何成功。

tables.py

import django_tables2 as tables

from django_tables2.utils import A


class CampaignsTable(tables.Table):
    """docstring for CampaignsTable"""
    id = tables.Column(verbose_name='#')
    name = tables.LinkColumn('ad_sets', verbose_name='Campaign Name', empty_values=())
    # name = tables.Column(verbose_name='Campaign Name')
    objective = tables.Column(verbose_name='Campaign Objective')
    effective_status = tables.Column(verbose_name='Campaign Effective Status')

    class Meta:
        attrs = {'class':'table table-striped table-bordered', 'id':'campaigns'}
        orderable = True

从上面我尝试将Campaign Name列转换为LinkColumn，即每个单元格都被解析为/ad_accounts/{{ ad_account.id }}/campaigns/{{ campaign.id }}/ad_sets的链接：

urls.py 代码段

url(
    r'^ad_accounts/(?P<ad_account_id>[^/]+)/campaigns/(?P<campaign_id>\d+)/$',
    CampaignDetailView.as_view(),
    name="ad_sets"

根据文档和this answer的建议，我需要在args=[A('pk')]中添加LinkColumn，但这样做会给我带来错误

ValueError at /ad_accounts/act_1100111250039687/
Failed lookup for key [pk] in <Campaign> {
    "effective_status": "PAUSED",
    "id": "6040446448677",
    "name": "test77",
    "objective": "CANVAS_APP_ENGAGEMENT"
}, when resolving the accessor pk

然后我尝试args=[A('id')]给了我：

NoReverseMatch at /ad_accounts/act_1100111250039687/
Reverse for 'ad_sets' with arguments '(u'6040446448677',)' and keyword arguments '{}' not found. 0 pattern(s) tried: []

我真的很困惑如何在单元格中添加链接以及args=[A('id')]正在做什么。任何帮助将不胜感激。

更新

刚试过：

name = tables.LinkColumn('ad_sets', args=[A('id')], kwargs={'ad_account.id', 'campaign.id'}, verbose_name='Campaign Name',
                             empty_values=())

它将我重定向到我的登录页面
