相关类型字段不显示值

Question

我有一个相关领域的“REGION_ID”是获得在这样

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), 
} 

另一个类从many2one字段中的值，但它不能做出正确的价值，而不是当我保存，它给了我这个：browse_record（budget.org_table，12）。为什么它没有返回值？我该如何解决它？

活动年份类

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表类

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.'), 
] 

Answer 1

在OpenERP的，当您使用related场，这是给基于它的价值或输出的type.例如type='char'，See other fields type 。

在你的情况下，你需要使用type='many2one'获得欲望输出。

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), 
}
