我有一个带有onchange方法的类,它从另一个模型中检索活动名称。当我运行它时,我得到这样的错误。
AttributeError:'在browse_record中找不到字段activity_name(budget.activity_year,16)'
任何人都可以说出为什么会这样,我该如何解决?
使用onchange方法的课程
class wpb(osv.osv):
_name = "wpb.wpb"
_description = "Work Program and Budget"
_columns = {
'activity_id' : fields.many2one("budget.activity_summary", "ID", type="char", size=64, ondelete="no action"),
'activity_name' : fields.char("Activity Name", type="char", size=64, ondelete="no action" ),
'region_id' : fields.related("activity_code", "region_id", type="char", string="Management Unit"),
'service_lvl' : fields.float("Service Level", digits=(4,2)),
'annual_work' : fields.float("Annual Work", digits=(4,2)),
}
def onchange_activity_code(self, cr, uid, ids, activity_id, context = None):
if activity_id:
names = self.pool.get('budget.activity_year').browse(cr, uid, activity_id, context=context)
return {'value': {'activity_name': names.activity_name }}
return {'value':{}}
xml视图
<record id="wpb_form" model="ir.ui.view">
<field name="name">wpb.wpb.form</field>

我试图获取活动名称字段的类
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),
'act_status' : fields.selection([
('1', 'All'),
('2', 'Active'),
('3', 'Inactive'),
], 'Status'),
}
_sql_constraints = [
('activity_yearcode_unique', 'UNIQUE(activity_yearcode)', 'Each activity code is unique.'),
]

您的activity_id
与budget.activity_summary
有关系,您可以从budget.activity_year
获得价值。我认为这可能与budget.activity_year
有关系。更改此关系并尝试使用on_change方法。
试试这个on_change
def onchange_activity_code(self, cr, uid, ids, activity_id, context = None):
res = {}
names = self.pool.get('budget.activity_summary').browse(cr, uid, activity_id, context=context)
if names:
res['activity_name'] = names.activity_name
return {'value': res}
请参阅其他on_change
格式,以便您更清楚地了解它。
希望这会对你有所帮助。

更新 onchange 方法
def onchange_activity_code(self, cr, uid, ids, activity_id, context = None):
if activity_id:
names = self.pool.get('budget.activity_year').browse(cr, uid, [activity_id], context=context)
return {'value': {'activity_name': names.activity_name }}
from openerp.osv import fields, osv
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),
'act_status' : fields.selection([
('1', 'All'),
('2', 'Active'),
('3', 'Inactive'),
], 'Status'),
}
_sql_constraints = [
('activity_yearcode_unique', 'UNIQUE(activity_yearcode)', 'Each activity code is unique.')
]
class wpb(osv.osv):
_name = "wpb.wpb"
_description = "Work Program and Budget"
_columns = {
'activity_id' : fields.many2one("budget.activity_summary", "ID", type="char", size=64, ondelete="no action"),
'activity_name' : fields.char("Activity Name", type="char", size=64, ondelete="no action" ),
'region_id' : fields.related("activity_code", "region_id", type="char", string="Management Unit"),
'service_lvl' : fields.float("Service Level", digits=(4,2)),
'annual_work' : fields.float("Annual Work", digits=(4,2)),
}
def onchange_activity_code(self, cr, uid, ids, activity_id, context = None):
if activity_id:
names = self.pool.get('budget.activity_year').browse(cr, uid, [activity_id], context=context)
return {'value': {'activity_name': names.activity_name }}
来自budget.activity_year对象的 activity_name
字段设置值。

名称的类型是记录列表,因此要浏览记录列表,必须定义元素。 在您的情况下,您可以键入:name [0] .activity_name - &gt;对于名称的第一个记录的activity_name。 原谅我的英语不好
