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
复制代码 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}
复制代码 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中共享
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 id="link_estate_property_action" model="ir.actions.act_window">
- <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 id="estate_property_search_view" model="ir.ui.view">
- <field name="name">estate.property.search</field>
- <field name="model">estate.property</field>
- <field name="arch" type="xml">
- <search>
-
- <field name="name" string="Title" />
- <separator/>
-
- <filter string="Available" name="state" domain="['|',('state', '=', 'New'),('state', '=', 'Offer Received')]"></filter>
- </search>
- </field>
- </record>
-
- </odoo>
复制代码 说明:- <field name="context">{'search_default_fieldName': content}</field>
复制代码 search_default_fieldName,其中fieldName 表示过滤器名称,即搜索视图中定义的、元素的name属性值
content 如果fieldName为搜索字段的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>
-
- <record id="estate_property_search_view" model="ir.ui.view">
- <field name="name">estate.property.search</field>
- <field name="model">estate.property</field>
- <field name="arch" type="xml">
- <search>
-
- <group expand="1" string="Group By">
- <filter string="朝向" name="garden_orientation" context="{'group_by':'garden_orientation'}"/>
- </group>
- </search>
- </field>
- </record>
-
- </odoo>
复制代码 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
复制代码 视图设计
- <?xml version="1.0"?>
- <odoo>
-
- <record id="estate_property_type_view_form" model="ir.ui.view">
- <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>
-
- <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" />
- </footer>
- </sheet>
- </form>
- </field>
- </record>
- </odoo>
复制代码 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.
复制代码 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],)
复制代码 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
复制代码 - 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

复制代码 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:- {'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'}, 'propertyTypeId': 1}

- _description = 'estate property tag'
- name = fields.Char(string='tag', required=True)
- color = fields.Integer(string='Color')
- @api.model
- def create(self, vals_list): # 通过重写模型的create或者write方法,调用该方法前修改上下文,然后在方法中通过self.env.context获取上下文中的目标key值,进而实现目标需求
- res = super(EstatePropertyTag, self).create(vals_list)
- # 获取上下文目标key值
- if not self.env.context.get('is_sync', True):
- # do something you need
- return res
复制代码- >>> self.env['estate.property.tag'].with_context(is_sync=False).create({'name': 'tag4', 'color': 4}).env.context
- {'lang': 'en_US', 'tz': 'Europe/Brussels', 'is_sync': False}
