Question

我有一个相关字段＆＃39; region_id＆＃39;从另一个类中的many2one字段中获取值，如此

 class activity_summary(osv.osv):
_name = "budget.activity_summary"
_rec_name = "activity_summarycode"
_columns = {
'activity_summarycode' : fields.many2one("budget.activity_year", "Activity Summary Code", ondelete= "no action", required=True ),
    'region_id' : fields.related("activity_summarycode", "mgmt_code", type="char", string = "Management Code", size=64, store = True),
}

但它没有给出正确的价值，相反，当我保存时，它给了我这个：browse_record（budget.org_table，12）。为什么不返回价值？我该怎么办呢？

活动年级

class activity_year(osv.osv):
_name = "budget.activity_year"
_description = "Activity year"
_rec_name = "activity_yearcode"
_columns = {
    'activity_yearcode' : fields.char("Activity Code", size=64, required=True),
'activity_name' : fields.char("Activity Name", size=128),
'mgmt_code' : fields.many2one("budget.org_table","Management Unit Code"),
    }
_sql_constraints = [
    ('activity_yearcode_unique', 'UNIQUE(activity_yearcode)', 'Each activity code is unique.'),
]

budget.org-table class

class org_table(osv.osv):
_name = "budget.org_table"
_rec_name = "org_code"
_columns = {
    'org_code' : fields.char("Code", size=64),
    'org_name' : fields.char("Name"),
  }
_sql_constraints = [
    ('org_code_unique', 'UNIQUE(org_code)', 'Each org_table ID is unique.'),
]

在OpenERP中，当您使用related字段时，它会根据它type.提供值或输出，例如type='char'，See other fields type

在您的情况下，您需要使用type='many2one'获取欲望输出。

试试这个，

class activity_summary(osv.osv):
    _name = "budget.activity_summary"
    _rec_name = "activity_summarycode"
    _columns = {
        'activity_summarycode' : fields.many2one("budget.activity_year", "Activity Summary Code", ondelete= "no action", required=True ),
        'region_id' : fields.related("activity_summarycode", "mgmt_code", type="many2one", string = "Management Code", relation="budget.activity_year", size=64, store = True),
}

相关类型字段未显示值
