Question

在odoo9中我覆盖了search_read方法。超级方法工作正常。返回的数据我想制作一个过滤器，过滤器在上下文中，该值在点击从视图出来的按钮时被赋予。

    <button name="status_instalacion" string="Instalación" type="action" icon="fa-wrench  fa-2x"  context="{'stage_id' : 1, 'current_id': active_id}"/>

当我在search_read方法中查询上下文时，会出现问题。它存在，但没有我放置的值

单击按钮的上下文：

self._context       {u＆＃39; lang＆＃39;：你＆＃39; en_US＆＃39;，你＆＃39; stage_id＆＃39;：1，你＆＃39; t：＆＃39;：错误，你＆＃39; uid＆＃39;： 1，你＆＃39; current_id＆＃39;：40，你＆＃39; tipo_validacion＆＃39;：你＆＃39; Sistemas Cr \ xedticos＆＃39;，你＆＃39; sistema_critico＆＃39;：你＆＃39; AGUA＆＃39; ;}

stage_id是我想要的值

read_search上的

上下文：

self._context       {u＆＃39; lang＆＃39;：你＆＃39; en_US＆＃39;，你＆＃39; bin_size＆＃39;：是的，你＆＃39; tipo_validacion＆＃39;：你＆＃39; Sistemas Cr \ xedticos＆＃39; ，你＆＃39;：错，你＆＃39;：1，       你好主意＆＃39;：错，你＆＃39; sistema_critico＆＃39;：你＆＃39; AGUA＆＃39;}

你可以看到＆＃39; stage_id＆＃39;价值缺失

尝试将值分配给类的属性，但值永远不会改变它始终是初始值。

from logging import getLogger
from openerp import api, fields, models

_logger = getLogger(__name__)


class MgmtsystemSistemasEquipos(models.Model):
    """ Equipos."""

    _name = 'mgmtsystem.sistemas.equipos'
    dmy = 99  # ---> this value never changes

    def dummy(self):       # ---> tried calling a function. not work
        return self.dmy

    def set_dummy(self, id):      # ----> set the value
        self.dmy = id or self.dmy

    codigo = fields.Char(
        string=u'Código',

        import pudb
        pu.db

        # save value to variable dmy to retrieve later
        id = self._context.get('stage_id')
        self.set_dummy(id)



    @api.model
    def search_read(
            self, domain=None, fields=None, offset=0,
            limit=None, order=None):

        import pudb
        pu.db

        # here the variable allways has the original value (99)
        current_stage_id = self.dmy
        current_stage_id = self.dummy()
        current_stage_id = getattr(self, dmy)


        res = super(MgmtsystemSistemasEquipos, self).search_read(
            domain, fields, offset, limit, order)

        current_id = res[0]['id']

        valid_protocols_ids = self._get_ids(
            current_stage_id, current_id,
            'mgmtsystem_equipos_protocolos',
            'mgmtsystem_equipos_protocolos_rel',
            'protocolo_id')

        # # remove ids
        res[0]['protocolos_ids'] = valid_protocols_ids
        res[0]['informes_ids'] = valid_informes_ids
        res[0]['anexos_ids'] = valid_anexos_ids

        return res


    # @api.multi
    def _get_ids(self, current_stage_id, current_id, model, model_rel, field_rel):

        import pudb
        pu.db

        # in this method the value of the variable is allways the original
        current_stage_id = self.dummy()

        sql = """ select a.id from
            %s as a
            join %s as b
            on a.id = b.%s where b.equipo_id = %s
            and a.stage_id = %s; """ % (model, model_rel, field_rel,
                                        current_id, current_stage_id)

        import psycopg2

        try:
            self.env.cr.execute(sql)
        except psycopg2.ProgrammingError, ex:
            message = 'Error trying to download data from server. \n {0} \n {1}'.format(ex.pgerror, sql)
            _logger.info(message)
            return False

        rows = self.env.cr.fetchall()
        list_of_ids = []

        for row in rows:
            list_of_ids.append(row[0])

        return list_of_ids

我不太了解Python，这就是我误解如何读取变量值的原因。

但话又说回来，为什么在search_read方法中修改了上下文？。

谢谢。

你应该尝试一下。

@api.model
def search_read(self, domain=None, fields=None, offset=0, limit=None, order=None):

    import pudb
    pu.db

    # Here you need to get the value from the context.
    current_stage_id = self._context.get('stage_id', getattr(self, dmy))

    res = super(MgmtsystemSistemasEquipos, self).search_read(domain=domain, fields=fields, offset=offset, limit=limit, order=order)

    current_id = res[0]['id']

    valid_protocols_ids = self._get_ids(
        current_stage_id, current_id,
        'mgmtsystem_equipos_protocolos',
        'mgmtsystem_equipos_protocolos_rel',
        'protocolo_id')

    # # remove ids
    res[0]['protocolos_ids'] = valid_protocols_ids
    res[0]['informes_ids'] = valid_informes_ids
    res[0]['anexos_ids'] = valid_anexos_ids

    return res

在你的代码中，这些行不起作用只是因为self中没有可用的记录集（正确的行为，search_read必须有@ api.model装饰器）。

    # here the variable allways has the original value (99)
    current_stage_id = self.dmy
    current_stage_id = self.dummy()
    current_stage_id = getattr(self, dmy)

所以只需删除那些和行并应用其他逻辑来获取数据。

覆盖方法中缺少Odoo 9上下文值
