Odoo 11 Development Cookbook - Second Edition - Second Edition

Overview of this book

Odoo is a full-featured open source ERP with a focus on extensibility. The flexibility and sustainability of open source are also a key selling point of Odoo. It is built on a powerful framework for rapid application development, both for back-end applications and front-end websites. Version 11 offers better usability and speed: a new design (as compared to the current Odoo Enterprise version) and a mobile interface. The book starts by covering Odoo installation and administration and Odoo Server deployment. It then delves into the implementation of Odoo modules, the different inheritance models available in Odoo. You will then learn how to define access rules for your data; how to make your application available in different languages; how to expose your data models to end users on the back end and on the front end; and how to create beautiful PDF versions of your data. By the end of the book, you will have a thorough knowledge of Odoo and will be able to build effective applications by applying Odoo development best practices

Reporting errors to the user

During method execution, it is sometimes necessary to abort the processing because an error condition was met. This recipe shows how to do this so that a helpful error message is displayed to the user when a method that writes a file to disk encounters an error.

Getting ready

To use this recipe, you need a method with an error condition. We will use the following one:

import os 
from odoo import models, fields, api 
 
class SomeModel(models.Model):
    _name = 'some.model'
    data = fields.Text('Data') 
 
    @api.multi 
    def save(self, filename): 
        path = os.path.join('/opt/exports', filename) 
        with open(path, 'w') as fobj: 
          ...
