相關類型字段不顯示值

Question

我有一個相關領域的「REGION_ID」是獲得在這樣

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), 
} 

另一個類從many2one字段中的值，但它不能做出正確的價值，而不是當我保存，它給了我這個：browse_record（budget.org_table，12）。爲什麼它沒有返回值？我該如何解決它？

活動年份類

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表類

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，當您使用related場，這是給基於它的價值或輸出的type.例如type='char'，See other fields type 。

在你的情況下，你需要使用type='many2one'獲得慾望輸出。

試試這個，

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), 
}
