django后台list_display中添加自定义字段

list_display = ("apply_prove",)
    def apply_prove(self, obj):
        if obj.prove == 1:
            return "<a href=‘/‘ target=‘_blank‘>申请认证</a>"
        else:
            return "<span>认证完成</span>"
apply_prove.short_description = ‘操作‘
apply_prove.allow_tags = True

#adminx.py文件
#由time表的tid连接到teacher表的tname

@xadmin.sites.register(models.order)
class TimeAdmin(object):
    list_display = (‘tid‘,‘get_tname‘,)

    def get_tname(self, obj):
        return ‘%s‘ % obj.tid.tname #☆☆☆☆☆
    get_tname.short_description = ‘老师‘
