我有一个父模型(Plant(，它在上下文中发送active_id(Plant_id(作为默认值：
class Plant(models.Model):
_name = 'db.plant'
_description = 'db.plant'
name = fields.Char("Name", required=True)
...
工厂视图与多个之间的关系：
<odoo>
<data>
<record id="plant_list_view" model="ir.ui.view">
<field name="name">db.plant.view</field>
<field name="model">db.plant</field>
<field name="arch" type="xml">
<tree>
<field name="name"/>
...
</tree>
</field>
</record>
<record id="plant_form_view" model="ir.ui.view">
<field name="name">db.form.view</field>
<field name="model">db.plant</field>
<field name="arch" type="xml">
<form>
<sheet>
<group string="Plant">
<field name="name"/>
...
</group>
<group string="Components">
<notebook>
<page string="Data Sources">
<field name="data_source_ids" context="{'default_plant_id': active_id}">
<tree >
<field name="name"/>
...
<!-- <field name="plant_id"/> -->
</tree>
</field>
</page>
</notebook>
</group>
</sheet>
</form>
</field>
</record>
<record id="plant_action" model="ir.actions.act_window">
<field name="name">plant</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">db.plant</field>
<field name="view_mode">tree,form</field>
</record>
</data>
和他的子模型(数据源(:
class DataSource(models.Model):
_name = 'db.data_source'
_description = 'db.data_source'
name = fields.Char("Name", required=True)
plant_id = fields.Many2one('db.plant', name="Plant", required=True)
数据源视图：
<odoo>
<data>
<record id="data_source_list_view" model="ir.ui.view">
<field name="name">db.data_source.view</field>
<field name="model">db.data_source</field>
<field name="arch" type="xml">
<tree>
<field name="name"/>
...
</tree>
</field>
</record>
<record id="data_source_form_view" model="ir.ui.view">
<field name="name">db.form.view</field>
<field name="model">db.data_source</field>
<field name="arch" type="xml">
<form>
<group>
<field name="name"/>
...
</group>
<group>
<field name="plant_id" domain="[('id', '=', context.default_plant_id)]" />
</group>
<group>
</group>
</form>
</field>
</record>
<record id="data_source_action" model="ir.actions.act_window">
<field name="name">Data Source</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">db.data_source</field>
<field name="view_mode">tree,form</field>
</record>
</data>
我知道default_plant_id是在子级中接收的，因为plant_id域只过滤我的plant_id，但我无法将其自动设置为默认值。我需要点击列表并选择我的plant_id(这是列表中唯一的元素(。
我还尝试通过两种方式在子级(data_source(中添加@api.on_change("plant_id"(：
选项1：
@api.onchange('plant_id')
def onchange_plant_id(self):
if self.plant_id:
context = dict(self._context or {})
return [(0,0,{'plant_id': context.get('default_plant_id')})]
给我一个异常：
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "/Users/albertocrespo/tools/odoo/odoo/http.py", line 640, in _handle_exception
return super(JsonRequest, self)._handle_exception(exception)
File "/Users/albertocrespo/tools/odoo/odoo/http.py", line 316, in _handle_exception
raise exception.with_traceback(None) from new_cause
AttributeError: 'list' object has no attribute 'get'
选项2(我不确定要发送什么作为响应，但写入语句也不起作用(：
@api.onchange('plant_id')
def onchange_your_many_to_one_field(self):
context = dict(self._context or {})
self.plant_id.write({'id':context.get('default_plant_id')})})
res = {}
return res
在保存之前，我需要在data_source视图中自动选择我的工厂作为选项。
在xml端上下文级别上不需要onchange方法或任何东西。您可以简单地在任意字段data_source_ids之间的关系中使用字段plant_id。
试试这个：
data_source_ids = fields.One2many("db.data_source", "plant_id")
