odoo模块的创建 openacademy学习笔记
odoo -u academy -d academyopenacademy官网完整教程
- 练习创建模块
使用上面的命令行创建一个空模块Open Academy，并将其安装在Odoo中。
odoo scaffold openacademy myaddons- 练习定义模型，
在openacademy模块中定义新的数据模型课程,每门课程包含两个字段，标题和描述，其中标题是必填字段。编辑文件openacademy/models/models.py以包含Course类。
openacademy/models/models.py
from odoo import models, fields, api
class Course(models.Model):
#定义了两个字段name,description
_name = 'openacademy.course'
name = fields.Char(string=<span class="hljs-string">"Title"</span>, required=<span class="hljs-keyword">True</span>)
description = fields.Text()
- 练习定义演示数据，
添加演示数据以填充Course模型的数据，编辑文件openacademy/demo/demo.xml来添加演示数据
openacademy/demo/demo.xml
<odoo>
<data>
<record model="openacademy.course" id="course0">
<field name="name">Course 0</field>
<field name="description">Course 0's description
Can have multiple lines
</field>
</record>
<record model="openacademy.course" id="course1">
<field name="name">Course 1</field>
<!-- no description for this one -->
</record>
<record model="openacademy.course" id="course2">
<field name="name">Course 2</field>
<field name="description">Course 2's description</field>
</record>
</data>
</odoo>
demo.xml如何起作用？
必须添加到data中
'data': [
# 'security/ir.model.access.csv',
'views/views.xml',
'views/templates.xml',
'demo/demo.xml',
],添加到demo中不起作用
- 练习定义新菜单项，
在开放学院菜单项下定义新菜单项来访问课程。用户应该能够：
显示所有课程的列表
建立或编辑课程
1.建立openacademy/views/openacademy.xml以创建操作和能够触发操作的菜单项。
2.添加这个文件到openacademy/__manifest__.py下的data列表。
编写菜单（menuitem）和行为(action)
<?xml version="1.0" encoding="UTF-8"?>
<odoo>
<data>
<!-- window action -->
<!-- The following tag is an action definition for a "window action", that is an action opening a view or a set of views -->
<record model="ir.actions.act_window" id="course_list_action">
<field name="name">Courses</field>
<field name="res_model">openacademy.course</field>
<field name="view_type">form</field>
<field name="view_mode">tree,form</field>
<field name="help" type="html">
<p class="oe_view_nocontent_create">Create the first course
</p>
</field>
</record>
<span class="hljs-comment"><!-- top level menu: no parent --></span>
<span class="hljs-tag"><<span class="hljs-name">menuitem</span> <span class="hljs-attr">id</span>=<span class="hljs-string">"main_openacademy_menu"</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"Open Academy"</span>/></span>
<span class="hljs-comment"><!-- A first level in the left side menu is needed
before using action= attribute --></span>
<span class="hljs-tag"><<span class="hljs-name">menuitem</span> <span class="hljs-attr">id</span>=<span class="hljs-string">"openacademy_menu"</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"Open Academy"</span>
<span class="hljs-attr">parent</span>=<span class="hljs-string">"main_openacademy_menu"</span>/></span>
<span class="hljs-comment"><!-- the following menuitem should appear *after*
its parent openacademy_menu and *after* its
action course_list_action --></span>
<span class="hljs-tag"><<span class="hljs-name">menuitem</span> <span class="hljs-attr">id</span>=<span class="hljs-string">"courses_menu"</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"Courses"</span> <span class="hljs-attr">parent</span>=<span class="hljs-string">"openacademy_menu"</span>
<span class="hljs-attr">action</span>=<span class="hljs-string">"course_list_action"</span>/></span>
<span class="hljs-comment"><!-- Full id location:
action="openacademy.course_list_action"
It is not required when it is the same module --></span>
<span class="hljs-tag"></<span class="hljs-name">data</span>></span>
</odoo>
- 练习使用XML定制窗体视图
建立课程对象的表单视图，显示课程的名称和描述字段。
- 练习notebook结构元素
在课程的表单视图中，将描述字段放在一个选项卡中，然后再添加选项卡放置其它字段。修改后的课程表单视图如下：
openacademy/views/openacademy.xml
<!--form视图 Course-->
<record model="ir.ui.view" id="view_form_openacademy_course">
<field name="name">course.form</field>
<field name="model">openacademy.course</field>
<field name="arch" type="xml">
<form string="Course Form">
<sheet>
<group>
<field name="name"/>
<field name="description"/>
</group>
<!--notebook标签页-->
<notebook>
<!--描述-->
<page string="Description">
<field name="description"/>
</page>
<span class="hljs-tag"></<span class="hljs-name">notebook</span>></span>
<span class="hljs-tag"></<span class="hljs-name">sheet</span>></span>
<span class="hljs-tag"></<span class="hljs-name">form</span>></span>
<span class="hljs-tag"></<span class="hljs-name">field</span>></span>
<span class="hljs-tag"></<span class="hljs-name">record</span>></span></code></pre>
notebook效果：
当然也可以用纯HTML页面写
- 练习搜索课程
通过标题和描述来搜索课程。
<!--搜索视图 Course-->
<record model="ir.ui.view" id="course_search_view">
<field name="name">course.search</field>
<field name="model">openacademy.course</field>
<field name="arch" type="xml">
<search>
<field name="name"/>
<field name="description"/>
<filter name="my_courses" string="My Courses" domain="[('responsible_id', '=', uid)]"/>
<group string="Group By">
<filter name="by_responsible" string="Responsible" context="{'group_by': 'responsible_id'}"/>
</group>
</search>
</field>
</record>
- 练习建立一个授课模型
在开放学院模块中，我们考虑一个授课模型：一个授课是在给定的时间中对给定的受众教授指定的课程。为授课建立模型，授课包括名称、开始时间、持续时间和席位数。添加操作和菜单项来显示新的模型。
openacademy/models.py
class Session(models.Model): _name = 'openacademy.session' name = fields.<span class="hljs-built_in">Char</span>(required=<span class="hljs-literal">True</span>)
start_date = fields.<span class="hljs-built_in">Date</span>()
duration = fields.Float(digits=(<span class="hljs-number">6</span>, <span class="hljs-number">2</span>), help=<span class="hljs-string">"Duration in days"</span>)
seats = fields.<span class="hljs-built_in">Integer</span>(<span class="hljs-built_in">string</span>=<span class="hljs-string">"Number of seats"</span>)
openacademy/views/openacademy.xml
<!-- session form view -->
<record model="ir.ui.view" id="session_form_view">
<field name="name">session.form</field>
<field name="model">openacademy.session</field>
<field name="arch" type="xml">
<form string="Session Form">
<sheet>
<group>
<field name="name"/>
<field name="start_date"/>
<field name="duration"/>
<field name="seats"/>
</group>
</sheet>
</form>
</field>
</record>
<span class="hljs-tag"><<span class="hljs-name">record</span> <span class="hljs-attr">model</span>=<span class="hljs-string">"ir.actions.act_window"</span> <span class="hljs-attr">id</span>=<span class="hljs-string">"session_list_action"</span>></span>

<span class="hljs-tag"><<span class="hljs-name">field</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"view_mode"</span>></span>tree,form<span class="hljs-tag"></<span class="hljs-name">field</span>></span>
<span class="hljs-tag"></<span class="hljs-name">record</span>></span>
<span class="hljs-tag"><<span class="hljs-name">menuitem</span> <span class="hljs-attr">id</span>=<span class="hljs-string">"session_menu"</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"Sessions"</span>
<span class="hljs-attr">parent</span>=<span class="hljs-string">"openacademy_menu"</span>
<span class="hljs-attr">action</span>=<span class="hljs-string">"session_list_action"</span>/></span>
- 练习Many2one关联
编辑Course和Session模型以反映他们与其它模型的关联：
- 课程有一个负责的用户；该字段的值是内置模型
res.users的记录
#class Course(models.Model)
responsible_id = fields.Many2one('res.users',
ondelete='set null', string="Responsible", index=True)- 一个授课有一个教师；该字段的值是内置模型
res.partner的记录
#class Session(models.Model)
instructor_id = fields.Many2one('res.partner', string="Instructor")- 授课与课程相关；该字段的值是
openacademy.course模型的记录，并且是必填项
#class Session(models.Model)
course_id = fields.Many2one('openacademy.course',
ondelete='cascade', string="Course", required=True)- 在模型中添加Many2one关联，并在视图显示
#form视图
<record model="ir.ui.view" id="view_form_openacademy_course">
<field name="name">course.form</field>
<field name="model">openacademy.course</field>
<field name="arch" type="xml">
<form string="Course Form">
<sheet>
<group>
<field name="name"/>
<field name="description"/>
<field name="responsible_id"/>
</group>
<!--notebook标签页-->
<notebook>
<!--描述-->
<page string="Description">
<field name="description"/>
</page>
<span class="hljs-tag"></<span class="hljs-name">notebook</span>></span>
<span class="hljs-tag"></<span class="hljs-name">sheet</span>></span>
<span class="hljs-tag"></<span class="hljs-name">form</span>></span>
<span class="hljs-tag"></<span class="hljs-name">field</span>></span>
<span class="hljs-tag"></<span class="hljs-name">record</span>></span></code></pre>
<record model="ir.ui.view" id="course_tree_view">
<field name="name">course.tree</field>
<field name="model">openacademy.course</field>
<field name="arch" type="xml">
<tree string="Course Tree">
<field name="name"/>
<field name="description"/>
<field name="responsible_id"/>
</tree>
</field>
</record>
多对一关系
关联字段
Many2one(other_model, ondelete='set null')
多对一字段
一个链接到其它对象的简单示例是这样的：
print foo.other_id.name
One2many(other_model, related_field)
一对多模型，通过for循环遍历
这是一个虚拟的关联，是Many2one的逆，One2many作为记录的容器，访问它将返回一个记录集（也可能是一个空记录集）：
for other in foo.other_ids:
print other.name
练习逆关联One2many
使用逆关联字段one2many，编辑模型以反映课程和授课之间的关系。
编辑Course类，并且加入字段到它的表单视图
#class Course(models.Model)
session_ids = fields.One2many(
'openacademy.session', 'course_id', string="Sessions")
<!--form视图 Course-->
<record model="ir.ui.view" id="course_form_view">
<field name="name">course.form</field>
<field name="model">openacademy.course</field>
<field name="arch" type="xml">
<form string="Course Form">
<sheet>
<group>
<field name="name"/>
<field name="responsible_id"/>
</group>
<!--notebook标签页-->
<notebook>
<!--描述-->
<page string="Description">
<field name="description"/>
</page>
<!--域-->
<page string="Sessions">
<field name="session_ids">
<tree string="Registered sessions">
<field name="name"/>
<!--instructor_id授课教师与课程的捆绑-->
<field name="instructor_id"/>
</tree>
</field>
</page>
</notebook>
</sheet>
</form>
</field>
</record>
notebook中添加了session
练习多对多关联many2many
在授课模型中添加关联字段many2many,将每次授课和参与的听众做关联，听众来自于内置模型res.partner。相应的调整对应的视图。
- 修改Session类并且加入字段到它的表单视图中
# class Session(models.Model)
attendee_ids = fields.Many2many('res.partner', string="Attendees")
视图
<record model="ir.ui.view" id="session_form_view">
<field name="name">session.form</field>
<field name="model">openacademy.session</field>
<field name="arch" type="xml">
<form string="Session Form">
<sheet>
<group>
<field name="name"/>
<field name="start_date"/>
<field name="duration"/>
<field name="seats"/>
</group>
<!--授课和参与的听众做关联，听众来自于内置模型res.partner-->
<label for="attendee_ids"/>
<field name="attendee_ids"/>
</sheet>
</form>
</field>
</record>
练习更改现有内容
- 使用模型继承，修改现有partner模型，添加
instructor布尔字段，以及对应表示"授课-讲师"关联的many2many字段
使用视图继承在partner的表单视图中显示这个字段
注意，这里是通过开发人员模式来查找视图外部ID并放置新字段的。
- 创建文件openacademy/models/partner.py并将其导入__init__.py
- 创建文件openacademy/views/partner.xml并将其添加到__manifest__.py

- 练习在关联字段上使用Domain，
当为授课选取讲师时，只有instructor值为True的讲师会被显示出来。
注意
声明为文字列表的domain会在服务端进行计算，不会出现在右侧的动态列表中，而声明为字符串的domain是在客户端进行计算的，字段名将出现在右侧列表。
#class Session(models.Model)
instructor_id = fields.Many2one('res.partner', string="Instructor",
domain=[('instructor', '=', True)])- 练习更复杂的domain，创建新的partner类别Techer/Level1和Techer/Level2.一个授课的教授人可以是讲师或者任意级别的教师。

视图继承路径\odoo\odoo10\odoo\addons\product\views\res_partner_views.xml
练习计算字段
- 加入座席占用百分比字段到授课模型。
- 在列表视图和表单视图中显示这个字段
以进度条的方式显示这个字段
#class Session(models.Model) taken_seats = fields.Float(string="Taken seats", compute='_taken_seats')
@api.depends(<span class="hljs-string">'seats'</span>, <span class="hljs-string">'attendee_ids'</span>) <span class="hljs-comment">#依赖的任一字段变化时（ORM or Form），触发该函数执行</span>

r.taken_seats = <span class="hljs-number">100.0</span> * len(r.attendee_ids) / r.seats
<field name="taken_seats" widget="progressbar"/>progresbar进度条
- 练习默认值
定义start_date默认值为今天
在授课类添加字段active，并且设置其默认值为True
class Session(models.Model): start_date = fields.Date(default=fields.Date.today) active = fields.Boolean(default=True)注意
Odoo 有内置规则：active字段值为False时记录不可见
- 练习
通过"onchange"机制显示的验证无效值，例如座位数为负数或者座位数多与参与者。
#class Session(models.Model)
@api.onchange('seats', 'attendee_ids')
def _verify_valid_seats(self):

}
if self.seats < len(self.attendee_ids):
return {
'warning': {
'title': "Too many attendees",
'message': "Increase seats or remove excess attendees",

- 练习添加Python约束，讲师不能在自己的授课出席人中
import exceptions
#class Session(models.Model):
@api.constrains('instructor_id', 'attendee_ids') #讲师不能在自己的授课出席人中
def _check_instructor_not_in_attendees(self):
for r in self:
if r.instructor_id and r.instructor_id in r.attendee_ids:
raise exceptions.ValidationError("A session's instructor can't be an attendee")
- 练习添加重复项，因为我们为课程名称添加了唯一性约束，所以不能再使用"复制"功能(表单->复制)。重写"复制"方法,允许复制课程对象，将原始名称更改为"原始名称的副本"。

工作流和安全
- 练习伪工作流
在授课模型上添加一个字段state，用于定义一个工作流程。授课存在三个可能的状态：Draft（草稿，默认值）、Confirmed（已确认）、Done（已完成）。在授课的form视图中，添加一个只读字段用于显示课程状态，并可以通过按钮来改变状态。有效的状态值迁移包括：
- Draft->Confirmed
- Confirmed->Draft
- Confirmed->Done
- Done->Draft
- 添加一个新的字段state
- 添加状态迁移方法，这个方法可以被form表单的按钮所调用，用以更改授课的状态
- 将相关按钮添加到授课的form视图
- openacademy/models.py
#class Session(models.Model):
state = fields.Selection([
('draft', "Draft"),
('confirmed', "Confirmed"),
('done', "Done"),

练习工作流
使用真正的授课工作流替换之前的伪工作流。修改授课的form视图，按钮将调用工作流而不是调用模型的方法。练习自动状态迁移
当超过一半座席被保留时，自动将授课的状态从Draft迁移到Confirmed。
当定义了工作流，需要卸载模块，否则原来定义好的数据无法进入工作流（可以直接修改数据库）
<record model="workflow.transition" id="session_auto_confirm_half_filled">
<field name="act_from" ref="draft"/>
<field name="act_to" ref="confirmed"/>
<field name="condition">taken_seats > 50</field>
</record>
</data>
</odoo>
- 练习服务器动作
用服务器动作替换用于同步授课状态的Python方法。工作流和服务器动作都可以从UI创建。

John Smit通过 设置->用户->用户 - 建立一个新组
session_read通过 设置->用户->组,这个组拥有对授课模型的读权限 - 编辑
John Smith用户，把他加入到session_read组 - 以
John Smith身份登录系统，检查权限是否正确。
练习
通过数据文件添加访问控制权限：- 建立一个组OpenAcademy / Manager，这个组对开放学院的所有模型都有完全权限。
- 让Session和Course对所有用户可读
- 建立新的文件openacademy/security/security.xml用来定义OpenAcademy Manager组
- 编辑文件openacademy/security/ir.model.access.csv来添加对模型的访问权限
- 最后更新openacademy/manifest.py来添加新的数据文件
openacademy/__manifest__.py
注意security.xml顺序,优先加载security.xml 然后加载csv,否则报错
Exception: Module loading openacademy failed: file openacademy/security/ir.model.access.csv could not be processed:

- 练习记录规则
为授课模型和OpenAcademy / Manager组添加记录规则，这个记录规则限制只有课程负责人可以对课程进行write和unlink操作，如果课程还没有负责人，这个组的所有用户都可以编辑它。在openacademy/security/security.xml文件中创建新的规则：
openacademy/security/security.xml

向导与国际化
-------
- 练习定义向导
创建一个向导模型，这个向导模型通过many2one关联授课模型，并通过many2many关联合作伙伴模型。添加新文件openacademy/wizard.py
openacademy/models/__init__.py
from . import models
from . import partner
from . import wizardopenacademy/wizard.py
# -*- coding: utf-8 -*-
from odoo import models, fields, api
class Wizard(models.TransientModel):
_name = 'openacademy.wizard'
session_ids = fields.Many2one(<span class="hljs-string">'openacademy.session'</span>,
string=<span class="hljs-string">"Session"</span>, required=<span class="hljs-keyword">True</span>)
attendee_ids = fields.Many2many(<span class="hljs-string">'res.partner'</span>, string=<span class="hljs-string">"Attendees"</span>)
- 练习启动向导
- 为向导定义一个form视图
- 在授课模型的上下文中添加action用于启动向导
- 给向导的session字段定义默认值；使用上下文参数self._context来获取当前授课
openacademy/wizard.py
class Wizard(models.TransientModel):
_name = 'openacademy.wizard'
<span class="hljs-function"><span class="hljs-keyword">def</span> <span class="hljs-title">_default_session</span><span class="hljs-params">(<span class="hljs-keyword">self</span>)</span></span>:

session_ids = fields.Many2one(<span class="hljs-string">'openacademy.session'</span>,
string=<span class="hljs-string">"Session"</span>, required=True, default=_default_session)
attendee_ids = fields.Many2many(<span class="hljs-string">'res.partner'</span>, string=<span class="hljs-string">"Attendees"</span>)

- 练习注册与会者
给向导添加按钮，并且实现相应的方法，将与会者添加到给定的授课。
<footer>
<!--订阅按钮-->
<button name="subscribe" type="object" string="Subscribe" class="oe_highlight"/>
<!--取消按钮-->
<button special="cancel" string="Cancel"/>
</footer>
- 练习与会者注册多个授课
修改向导模型，以便与会者可以注册到多个授课
class Wizard(models.TransientModel): _name = 'openacademy.wizard' <span class="hljs-function"><span class="hljs-keyword">def</span> <span class="hljs-title">_default_sessions</span><span class="hljs-params">(<span class="hljs-keyword">self</span>)</span></span>:

翻译一个模块
为已经安装的Odoo模块选择第二语言。使用Odoo提供的功能对模块进行翻译。
- 创建目录
openacademy/i18n/ - 安装任意一种你希望的语言 （设置->翻译->加载翻译 ）
- 同步翻译术语（设置->翻译->应用程序术语->同步术语）
- 导出不指定语言的翻译模板文件（设置->翻译->导入/导出->导出翻译），保存在
openacademy/i18n/ - 导出指定语言的翻译文件（设置->翻译->导入/导出->导出翻译），保存在
openacademy/i18n/ - 打开导出的翻译文件（使用任意一款文本编辑软件或者专用的PO文件编辑器，例如POEdit然后翻译其中的术语）
- 在
models.py文件中，为odoo._方法添加一个导入声明，并且标记需要翻译的字符串 - 重复3-6的步骤
实际上添加i18n这个文件夹，放入导出的po文件zh_cn.po文件，必须重新安装模块后，整个翻译才会生效
openacademy/models.py
