今天的實作

• 創造表單，跟搜尋功能
• Check ISBN button
• web測試

表單是給管理者新增書籍:
到views底下新增library_menu.xml 以下code就能輸入書的基本資料，用group分別列出要輸入的資料

<odoo>
  <record id="view_form_book" model="ir.ui.view">
    <field name="name">Book Form</field>
    <field name="model">library.book</field>
    <field name="arch" type="xml">

    <form>
      <header>
        <button name="button_check_isbn" type="object"
          string="Check ISBN" />
      </header>
      <sheet>
        <group name="group_top">
          <group name="group_left">
        <field name="name" />
        <field name="author_ids" widget="many2many_tags" />
        <field name="publisher_id" />
        <field name="date_published" />
          </group>
          <group name="group_right">
        <field name="isbn" />
        <field name="active" />
        <field name="image" widget="image" />
          </group>
        </group>
      </sheet>
    </form>

    </field>
  </record>
 </odoo>

新增書籍後，顯示的內容能自行定義，另外也能使用搜尋
到views/book_view.xml，以下code定義顯示的內容，包含書名、作者、出版社、出版日期:

<record id="view_tree_book" model="ir.ui.view">
<field name="name">Book List</field>
<field name="model">library.book</field>
<field name="arch" type="xml">
  <tree>
    <field name="name"/>
    <field name="author_ids" widget="many2many_tags" />
    <field name="publisher_id"/>
    <field name="date_published"/>
  </tree>
</field>
</record>

搜尋功能一樣在book_view.xml裡新增:

<record id="view_search_book" model="ir.ui.view">
 <field name="name">Book Filters</field>
 <field name="model">library.book</field>
 <field name="arch" type="xml">
   <search>
     <field name="publisher_id"/>
     <filter name="filter_inactive"
             string="Inactive"
             domain="[('active','=',True)]"/>
     <filter name="filter_active"
             string="Active"
             domain="[('active','=',False)]"/>
   </search>
 </field>
</record>

Check ISBN 的按鈕，已經先做好了，會出現在新增書籍的上放，這邊就是要讓功能啟用。
到models/library_book.py裡，來確認ISBN是否有效:

def _check_isbn(self):
  self.ensure_one()
  digits = [int(x) for x in self.isbn if x.isdigit()]
  if len(digits) == 13:
      ponderations = [1, 3] * 6
      terms = [a * b for a, b in zip(digits[:12], ponderations)]
      remain = sum(terms) % 10
      check = 10 - remain if remain != 0 else 0
      return digits[-1] == check

def button_check_isbn(self):
      for book in self:
          if not book.isbn:
              raise ValidationError("Please provide an ISBN for %s" % book.name)
          if book.isbn and not book._check_isbn():
              raise ValidationError("%s ISBN is invalid" % book.isbn)
      return True

web測試我們來做一個書籍清單，讓使用者看到目前的書籍。
我們先到library_app/init.py裡新增，新增controllers目錄:

from . import controllers

ibrary_app/controllers/init.py裡新增，根據main來做調整:

from . import main

library_app/controllers/main.py：

from odoo import http

class Books(http.Controller):

  @http.route("/library/books")
  def list(self, **kwargs):
      Book = http.request.env["library.book"]
      books = Book.search([])
      return http.request.render(
          "library_app.book_list_template",
          {"books": books}
      )

在到views/book_list_template.xml

<odoo>

<template id="book_list_template" name="Book List">
<div id="wrap" class="container">
  <h1>Books</h1>
    <t t-foreach="books" t-as="book">
      <div class="row">
        <span t-field="book.name" />,
        <span t-field="book.date_published" />,
        <span t-field="book.publisher_id" />
      </div>
    </t>
</div>
</template>

</odoo>

最後進入http://my-server/library/books，這樣簡單的書本清單就有了。
