Django Admin内联递归ManyToMany

Question

我有以下模型与自身的多对多关系

class Ticket(models.Model):

    STATUS = (
        (0, "Open"),
        (1, "Closed"),
    )
    status = models.SmallIntegerField(default=0,choices=STATUS)
    title = models.CharField(max_length=100)
    replies = models.ManyToManyField('self')
    description = models.TextField()

我试图使用以下代码将此模型显示为管理员中的内联

class TicketReply(admin.TabularInline):
    model = Ticket.replies.through

但是我一直收到这个错误

<class 'tsn.ticket.models.Ticket_replies'> has more than 1 ForeignKey to <class 'tsn.ticket.models.Ticket'>

所以我这样做错了,还是不支持？

Answer 1

可能是它'迟到了,但我尝试回答这个问题.Ticket.replies.through是一个管理多对多关系的表,它包含from_ticket和to_ticket(FK到模型Ticket)字段,您可以将此字段设置为TabularInline的选项fk_name.

class TicketReply(admin.TabularInline):
    model = Ticket.replies.through
    fk_name = 'from_ticket'
