odoo模塊的創建 openacademy學習筆記
odoo -u academy -d academyopenacademy官網完整教程
- 練習創建模塊
使用上面的命令行創建一個空模塊Open Academy，並將其安裝在Odoo中。
odoo scaffold openacademy myaddons- 練習定義模型，
在openacademy模塊中定義新的數據模型課程,每門課程包含兩個字段，標題和描述，其中標題是必填字段。編輯文件openacademy/models/models.py以包含Course類。
openacademy/models/models.py
from odoo import models, fields, api
class Course(models.Model):
#定義了兩個字段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()
- 練習定義演示數據，
添加演示數據以填充Course模型的數據，編輯文件openacademy/demo/demo.xml來添加演示數據
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？
必須添加到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
- 練習定義新菜單項，
在開放學院菜單項下定義新菜單項來訪問課程。用戶應該能夠：
顯示所有課程的列表
建立或編輯課程
1.建立openacademy/views/openacademy.xml以創建操作和能夠觸發操作的菜單項。
2.添加這個文件到openacademy/__manifest__.py下的data列表。
編寫菜單（menuitem）和行為(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>
- 練習使用XML定制窗體視圖
建立課程對象的表單視圖，顯示課程的名稱和描述字段。
- 練習notebook結構元素
在課程的表單視圖中，將描述字段放在一個選項卡中，然后再添加選項卡放置其它字段。修改后的課程表單視圖如下：
openacademy/views/openacademy.xml
<!--form視圖 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標簽頁-->
<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：
當然也可以用純HTML頁面寫
- 練習搜索課程
通過標題和描述來搜索課程。
<!--搜索視圖 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>
- 練習建立一個授課模型
在開放學院模塊中，我們考慮一個授課模型：一個授課是在給定的時間中對給定的受眾教授指定的課程。為授課建立模型，授課包括名稱、開始時間、持續時間和席位數。添加操作和菜單項來顯示新的模型。
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"/>

</field>
</record>

<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>
- 練習Many2one關聯
編輯Course和Session模型以反映他們與其它模型的關聯：
- 課程有一個負責的用戶；該字段的值是內置模型
res.users的記錄
#class Course(models.Model)
responsible_id = fields.Many2one('res.users',
ondelete='set null', string="Responsible", index=True)- 一個授課有一個教師；該字段的值是內置模型
res.partner的記錄
#class Session(models.Model)
instructor_id = fields.Many2one('res.partner', string="Instructor")- 授課與課程相關；該字段的值是
openacademy.course模型的記錄，並且是必填項
#class Session(models.Model)
course_id = fields.Many2one('openacademy.course',
ondelete='cascade', string="Course", required=True)- 在模型中添加Many2one關聯，並在視圖顯示
#form視圖
<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標簽頁-->

<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>
多對一關系
關聯字段
Many2one(other_model, ondelete='set null')
多對一字段
一個鏈接到其它對象的簡單示例是這樣的：
print foo.other_id.name
One2many(other_model, related_field)
一對多模型，通過for循環遍歷
這是一個虛擬的關聯，是Many2one的逆，One2many作為記錄的容器，訪問它將返回一個記錄集（也可能是一個空記錄集）：
for other in foo.other_ids:
print other.name
練習逆關聯One2many
使用逆關聯字段one2many，編輯模型以反映課程和授課之間的關系。
編輯Course類，並且加入字段到它的表單視圖
#class Course(models.Model)
session_ids = fields.One2many(
'openacademy.session', 'course_id', string="Sessions")
<!--form視圖 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標簽頁-->
<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授課教師與課程的捆綁-->
<field name="instructor_id"/>
</tree>
</field>
</page>
</notebook>
</sheet>
</form>
</field>
</record>
notebook中添加了session
練習多對多關聯many2many
在授課模型中添加關聯字段many2many,將每次授課和參與的聽眾做關聯，聽眾來自於內置模型res.partner。相應的調整對應的視圖。
- 修改Session類並且加入字段到它的表單視圖中
# class Session(models.Model)
attendee_ids = fields.Many2many('res.partner', string="Attendees")
視圖
<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>
<!--授課和參與的聽眾做關聯，聽眾來自於內置模型res.partner-->
<label for="attendee_ids"/>
<field name="attendee_ids"/>
</sheet>
</form>
</field>
</record>
練習更改現有內容
- 使用模型繼承，修改現有partner模型，添加
instructor布爾字段，以及對應表示"授課-講師"關聯的many2many字段
使用視圖繼承在partner的表單視圖中顯示這個字段
注意，這里是通過開發人員模式來查找視圖外部ID並放置新字段的。
- 創建文件openacademy/models/partner.py並將其導入__init__.py
- 創建文件openacademy/views/partner.xml並將其添加到__manifest__.py

- 練習在關聯字段上使用Domain，
當為授課選取講師時，只有instructor值為True的講師會被顯示出來。
注意
聲明為文字列表的domain會在服務端進行計算，不會出現在右側的動態列表中，而聲明為字符串的domain是在客戶端進行計算的，字段名將出現在右側列表。
#class Session(models.Model)
instructor_id = fields.Many2one('res.partner', string="Instructor",
domain=[('instructor', '=', True)])- 練習更復雜的domain，創建新的partner類別Techer/Level1和Techer/Level2.一個授課的教授人可以是講師或者任意級別的教師。

class Session(models.Model): start_date = fields.Date(default=fields.Date.today) active = fields.Boolean(default=True)注意
Odoo 有內置規則：active字段值為False時記錄不可見
- 練習
通過"onchange"機制顯示的驗證無效值，例如座位數為負數或者座位數多與參與者。
#class Session(models.Model)
@api.onchange('seats', 'attendee_ids')
def _verify_valid_seats(self):
if self.seats < 0:
return {
'warning': {
'title': "Incorrect 'seats' value",
'message': "The number of available seats may not be negative",
},
}
if self.seats < len(self.attendee_ids):
return {
'warning': {
'title': "Too many attendees",
'message': "Increase seats or remove excess attendees",
},
}
- 練習添加Python約束，講師不能在自己的授課出席人中
import exceptions
#class Session(models.Model):
@api.constrains('instructor_id', 'attendee_ids') #講師不能在自己的授課出席人中
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")
- 練習添加重復項，因為我們為課程名稱添加了唯一性約束，所以不能再使用"復制"功能(表單->復制)。重寫"復制"方法,允許復制課程對象，將原始名稱更改為"原始名稱的副本"。
#class Course(models.Model)
@api.multi
def copy(self, default=None):
default = dict(default or {})
print '--------------'
print self.name
print '--------------'
copied_count = self.search_count(

if not copied_count:
new_name = u"Copy of {}".format(self.name)
else:
new_name = u"Copy of {} ({})".format(self.name, copied_count)
default[<span class="hljs-string">'name'</span>] = new_name

工作流和安全
- 練習偽工作流
在授課模型上添加一個字段state，用於定義一個工作流程。授課存在三個可能的狀態：Draft（草稿，默認值）、Confirmed（已確認）、Done（已完成）。在授課的form視圖中，添加一個只讀字段用於顯示課程狀態，並可以通過按鈕來改變狀態。有效的狀態值遷移包括：
- Draft->Confirmed
- Confirmed->Draft
- Confirmed->Done
- Done->Draft
- 添加一個新的字段state
- 添加狀態遷移方法，這個方法可以被form表單的按鈕所調用，用以更改授課的狀態
- 將相關按鈕添加到授課的form視圖
- openacademy/models.py
#class Session(models.Model):
state = fields.Selection([
('draft', "Draft"),
('confirmed', "Confirmed"),
('done', "Done"),

練習工作流
使用真正的授課工作流替換之前的偽工作流。修改授課的form視圖，按鈕將調用工作流而不是調用模型的方法。練習自動狀態遷移
當超過一半座席被保留時，自動將授課的狀態從Draft遷移到Confirmed。
當定義了工作流，需要卸載模塊，否則原來定義好的數據無法進入工作流（可以直接修改數據庫）
<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>
- 練習服務器動作
用服務器動作替換用於同步授課狀態的Python方法。工作流和服務器動作都可以從UI創建。

- 練習
通過Odoo界面添加訪問控制權限
建立一個新用戶John Smit，然后建立OpenAcademy/Session Read組，並賦予這個組對授課模型的讀權限。
- 建立一個新用戶
John Smit通過 設置->用戶->用戶 - 建立一個新組
session_read通過 設置->用戶->組,這個組擁有對授課模型的讀權限 - 編輯
John Smith用戶，把他加入到session_read組 - 以
John Smith身份登錄系統，檢查權限是否正確。
練習
通過數據文件添加訪問控制權限：- 建立一個組OpenAcademy / Manager，這個組對開放學院的所有模型都有完全權限。
- 讓Session和Course對所有用戶可讀
- 建立新的文件openacademy/security/security.xml用來定義OpenAcademy Manager組
- 編輯文件openacademy/security/ir.model.access.csv來添加對模型的訪問權限
- 最后更新openacademy/manifest.py來添加新的數據文件
openacademy/__manifest__.py
注意security.xml順序,優先加載security.xml 然后加載csv,否則報錯
Exception: Module loading openacademy failed: file openacademy/security/ir.model.access.csv could not be processed:

- 練習記錄規則
為授課模型和OpenAcademy / Manager組添加記錄規則，這個記錄規則限制只有課程負責人可以對課程進行write和unlink操作，如果課程還沒有負責人，這個組的所有用戶都可以編輯它。在openacademy/security/security.xml文件中創建新的規則：
openacademy/security/security.xml

向導與國際化
-------
- 練習定義向導
創建一個向導模型，這個向導模型通過many2one關聯授課模型，並通過many2many關聯合作伙伴模型。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>)
- 練習啟動向導
- 為向導定義一個form視圖
- 在授課模型的上下文中添加action用於啟動向導
- 給向導的session字段定義默認值；使用上下文參數self._context來獲取當前授課
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>)
openacademy/views/openacademy.xml

- 練習注冊與會者
給向導添加按鈕，並且實現相應的方法，將與會者添加到給定的授課。
<footer>
<!--訂閱按鈕-->
<button name="subscribe" type="object" string="Subscribe" class="oe_highlight"/>
<!--取消按鈕-->
<button special="cancel" string="Cancel"/>
</footer>
- 練習與會者注冊多個授課
修改向導模型，以便與會者可以注冊到多個授課
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>:

翻譯一個模塊
為已經安裝的Odoo模塊選擇第二語言。使用Odoo提供的功能對模塊進行翻譯。
- 創建目錄
openacademy/i18n/ - 安裝任意一種你希望的語言 （設置->翻譯->加載翻譯 ）
- 同步翻譯術語（設置->翻譯->應用程序術語->同步術語）
- 導出不指定語言的翻譯模板文件（設置->翻譯->導入/導出->導出翻譯），保存在
openacademy/i18n/ - 導出指定語言的翻譯文件（設置->翻譯->導入/導出->導出翻譯），保存在
openacademy/i18n/ - 打開導出的翻譯文件（使用任意一款文本編輯軟件或者專用的PO文件編輯器，例如POEdit然后翻譯其中的術語）
- 在
models.py文件中，為odoo._方法添加一個導入聲明，並且標記需要翻譯的字符串 - 重復3-6的步驟
實際上添加i18n這個文件夾，放入導出的po文件zh_cn.po文件，必須重新安裝模塊后，整個翻譯才會生效
openacademy/models.py
