context用法总结
获取上下文
>>> self.env.context # 返回字典数据,等价于 self._context
{'lang': 'en_US', 'tz': 'Europe/Brussels'}
>>> self._context
{'lang': 'en_US', 'tz': 'Europe/Brussels'}
>>> recordSet.env.context # 注意,上下文是和记录集绑定的,上述的self也代表记录集
设置上下文
Model.with_context([context][, **overrides])
-> records[源代码]
返回附加到扩展上下文的此记录集的新版本。
扩展上下文是提供的合并了overrides
的context
,或者是合并了overrides
当前context
# current context is {'key1': True}
r2 = records.with_context({}, key2=True)
# -> r2._context is {'key2': True}
r2 = records.with_context(key2=True)
# -> r2._context is {'key1': True, 'key2': True}
需要注意的是,上下文是和记录集绑定的,修改后的上下文并不会在其它记录集*享
应用场景示例
用于action,为关联视图添加默认搜索、过滤条件
视图定义
为设置action打开的tree列表视图,添加默认搜索,搜索条件为 state
字段值等于True
<?xml version="1.0"?>
<odoo>
<record >
<field name="name">Properties</field>
<field name="res_model">estate.property</field>
<field name="view_mode">tree,form</field>
<field name="context">{'search_default_state': True}</field>
</record>
<record >
<field name="name">estate.property.search</field>
<field name="model">estate.property</field>
<field name="arch" type="xml">
<search>
<!-- 搜索 -->
<field name="name" string="Title" />
<separator/>
<!-- 筛选 -->
<filter string="Available" name="state" domain="['|',('state', '=', 'New'),('state', '=', 'Offer Received')]"></filter>
</search>
</field>
</record>
<!--此处代码略...-->
</odoo>
说明:
<field name="context">{'search_default_fieldName': content}</field>
search_default_fieldName
,其中fieldName
表示过滤器名称,即搜索视图中定义的<field>
、<filter>
元素的name
属性值
content
如果fieldName
为搜索字段<field>
的name
属性值,那么content
表示需要搜索的内容,输入内容是字符串,则需要添加引号,形如'test'
;如果fieldName
为搜索过滤器<filter>
的name
属性值,那么content
表示布尔值,该值为真,则表示默认开启name
所代表的过滤器,否则不开启。
用于搜索视图,添加分组查询条件
视图设计
<?xml version="1.0"?>
<odoo>
<!--此处代码略...-->
<record >
<field name="name">estate.property.search</field>
<field name="model">estate.property</field>
<field name="arch" type="xml">
<search>
<!-- 分组 -->
<group expand="1" string="Group By">
<filter string="朝向" name="garden_orientation" context="{'group_by':'garden_orientation'}"/>
</group>
</search>
</field>
</record>
<!--此处代码略...-->
</odoo>
说明:'group_by': '分组字段名称'
用于视图对象按钮,传递数据给模型方法
模型设计
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from odoo import models, fields, api
class EstatePropertyType(models.Model):
_name = 'estate.property.type'
_description = 'estate property type'
name = fields.Char(string='name', required=True, help='help text')
property_ids = fields.One2many('estate.property', 'property_type_id')
offer_ids = fields.One2many('estate.property.offer', 'property_type_id')
offer_count = fields.Integer(compute='_compute_offer_count')
@api.depends('offer_ids.price')
def _compute_offer_count(self):
for record in self:
record.offer_count = len(record.mapped('offer_ids.price'))
@api.model
def action_confirm(self, *args):
print(self, self.env.context, args)
# ... do something else
视图设计
<?xml version="1.0"?>
<odoo>
<!--此处代码略...-->
<record >
<field name="name">estate.property.type.form</field>
<field name="model">estate.property.type</field>
<field name="arch" type="xml">
<form string="Property Type">
<sheet>
<!--此处代码略...-->
<field name="offer_count">
<field name="property_ids">
<tree string="Properties">
<field name="name"/>
<field name="expected_price" string="Expected Price"/>
<field name="state" string="Status"/>
</tree>
</field>
<footer>
<button name="action_confirm" type="object" context="{'currentRecordID': active_id, 'offer_count':offer_count, 'property_ids': property_ids}" string="确认" class="oe_highlight"/>
</footer>
</sheet>
</form>
</field>
</record>
</odoo>
说明:context
属性值中的字典的键值如果为模型中定义的字段名称,则该字段名称必须以<field>
元素的形式,出现在模型对应的视图(即不能是内联视图,比如内联Tree列表)中,否则会出现类似错误提示:
Field offer_count used in context.offerCount ({'offerCount': offer_count}) must be present in view but is missing.
点击界面按钮后,服务端打印日志如下
estate.property.type() {'lang': 'en_US', 'tz': 'Europe/Brussels', 'uid': 2, 'allowed_company_ids': [1], 'params': {'action': 165, 'cids': 1, 'id': 1, 'menu_id': 70, 'model': 'estate.property.type', 'view_type': 'form'}, 'currentRecordID': 1, 'offer_count': 4, 'property_ids': [[4, 49, False], [4, 48, False]]} ([1],)
说明:args
从日志来看,args
接收了当前记录ID
注意:
-
如果将
def action_confirm(self, *args)
改成def action_confirm(self, arg)
,服务端控制台会收到类似如下告警(虽然点击按钮后,服务端不会抛异常):2023-02-06 01:28:53,848 28188 WARNING odoo odoo.addons.base.models.ir_ui_view: action_confirm on demo.wizard has parameters and cannot be called from a button
-
如果将
def action_confirm(self, *args)
改成def action_confirm(self)
,则点击页面确认按钮时,服务端会报错误,如下:TypeError: action_confirm2() takes 1 positional argument but 2 were given

打开上述视图(即加载内联Tree视图)时,会自动调用estate.property
模型的read
方法,服务端控制台输出如下:
