Creating fields

After creating a new model, the next step is to add fields to it. Odoo supports all the basic data types expected, such as text strings, integers, floating point numbers, Booleans, dates, date-times, and image/binary data.

Some field names are special, either because they are reserved by the ORM for special purposes, or because some built-in features make use of some default field names.

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

Basic field types

We now have a Stage model and we will expand it to add some additional fields. We should edit the todo_stage/models/todo_task_stage_model.py file and add extra field definitions to make it look like this:

class Stage(models.Model): 
    _name = 'todo.task.stage' 
    _description = 'To-do Stage' 
    _order = 'sequence,name'
# String fields: 
    name = fields.Char('Name') 
    desc = fields.Text('Description') 
    state = fields.Selection( 
        [('draft','New'),
         ('open','Started'),
         ('done','Closed...
