This book is meant for developers who have basic knowledge of the Python programming language, as the Odoo backend runs on Python. In Odoo, data files are created with XML, so basic knowledge of XML is required.

This book also covers the backend JavaScript framework, point-of-sale applications, and the website builder, which requires basic knowledge JavaScript, jQuery, and Bootstrap 4.

The community edition of Odoo is open source and freely available, but a few features, including IoT, cohort, and dashboard, are available only in the Enterprise edition, so to follow along with that recipe, you will need the Enterprise edition.

To follow Chapter 24, IoT Box, you will require the Raspberry Pi 3 Model B+, which is available at https://www.raspberrypi.org/products/raspberry-pi-3-model-b-plus/.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

{ 
    'name': "My library",
    'summary': "Manage books easily",
    'description': """Long description""", 
    'author': "Your name", 
    'website': "http://www.example.com", 
    'category': 'Uncategorized', 
    'version': '12.0.1', 
    'depends': ['base'], 
    'data': ['views.xml'], 
    'demo': ['demo.xml'], 
} 

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

from odoo import models, fields   
class LibraryBook(models.Model): 
    _name = 'library.book' 
    name = fields.Char('Title', required=True) 
    date_release = fields.Date('Release Date')
    author_ids = fields.Many2many(
        'res.partner', 
         string='Authors'
    )

Any command-line input or output is written as follows:

$ sudo apt-get update

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Odoo has special support for monetary values related to a currency."
