Question

我需要你的帮助。我是django初学者，我无法使用django-tables2中的linkcolumn。我真的很失望，因为我确信这很简单，但直到现在，它还不起作用。我提前感谢你给我的问题所给予的时间，如果它是简单的愚蠢请求你原谅; - ）

总结：

index.html返回一个django-tables2表，一切正常
我想更改列的数据＆＃34; name＆＃34;超链接（使用linkcolumn）与目标＆＃34; ... / Audit / 1 /＆＃34;其中1来自点击行的pk

Answer 1

您的网址正则表达式有一个命名组，因此grid_id应该是一个关键字参数。使用

name = tables.LinkColumn('detail', args={'grid_id': A('pk')})

Linkcolumn不能正常工作django-tables2
