FLASK-ADMIN顯示列表中增長自定義連接

一個需求就是在flask-admin的表格中放入一個根據組id外鍵生成的連接,點擊後跳轉到組

from flask_admin.model.template import EndpointLinkRowAction, LinkRowAction
#重載類,增長row.group_id這個外鍵id    
class glink(LinkRowAction):
        def render(self, context, row_id, row):
            m = self._resolve_symbol(context, 'row_actions.link')
            
            if isinstance(self.url, string_types):
                row_group_id = row.group_id
                url = self.url.format(row_id=row_id, row_group_id=row_group_id)
            else:
                url = self.url(self, row_id, row)
            return m(self, url)


column_extra_row_actions = [
#注意圖標生成在原有的編輯和刪除的小圖標後面,先根據外鏈的id拼出url
        glink('glyphicon glyphicon-user', '/admin/group/edit/?url=%2Fadmin%2Fgroup%2F&id={row_group_id}'),
        EndpointLinkRowAction('glyphicon glyphicon-test', 'user.index_view')
    ]

以上代碼寫在class UserModelView(ModelView): 中
