Hi ,
I want to update model from web controller , but I got this error when getting the current record id :
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'


<form action="/update/teacher">
        <input type="text" class="form-control" id="teacher_name" name="teacher_name"
               t-att-value="teacher_id.teacher_name"/>
    <button type="submit" class="btn btn-default">Submit</button>
</form>


@http.route('/update/teacher', type="http", website=True, auth="public")
    def update_teacher(self, **kw):
        http.request.env['academy.teacher'].browse(kw.get('id')).write(
            {
                'teacher_name': kw.get('teacher_name')
            }
            )

Any help please ?
Thanks.
