Creating fields

Having created a new model, the next step is to add fields to it. Odoo supports all the basic data types that are expected, such as text strings, integers, floating-point numbers, Booleans, dates and time, and image or binary data.

Let's explore the several types of fields available in Odoo.

class Book(models.Model):

    _description = "Book"
    # String fields:
    name = fields.Char("Title")
    isbn = fields.Char("ISBN")
    book_type = fields.Selection(
        [("paper","Paperback"...
