Hey, i have made a custom porta view for myself which displays attendance and then i had another class in controller which calls another template with a diff url and i am trying to open the detail of one attendance by clicking on it. Just as it happens in Sale order for portal. I am unable to open the page when i click the link as it gives me error as "Page 404 not found". 

Here is the code for my redirection, Kindly check and tell

class NewAttendView(http.Controller):
    @http.route('/attendance_line/{{order.id}}', type='http', auth='public', website=True)
    def this_attend_detail(self, **kwargs):
        new_attend_detail = request.env['op.attendance.sheet'].sudo().search([])
        return request.render('attendance_website.attendance_lines', {'attendance_line': new_attend_detail})

    @http.route('/attendance_line/{{order.id}}', type='http', auth='public', website=True)
    def that_attend_rights(self, new_attend_detail=None):
        new_attend_detail = request.env['op.attendance.sheet'].browse()
        return request.render('attendance_website.attendance_lines', {'attendance_line': new_attend_detail})

XML line of code

<a t-attf-href="/attendance_line/{{order.id}}?{{keep_query()}}">
