Creating fields

After creating a new model, the next step is to add fields to it. Let's explore the several types of fields available in Odoo.

Basic field types

We now have a Stage model and will expand it to add some additional fields. We should edit the todo_ui/todo_model.py file, by removing some unnecessary attributes included before for the purpose of explanation, making it look like this:

class Stage(models.Model):
    _name = 'todo.task.stage'
    _order = 'sequence,name'
    # String fields:
    name = fields.Char('Name', 40)
    desc = fields.Text('Description')
    state = fields.Selection(
        [('draft','New'), ('open','Started'),('done','Closed')],
        'State')
    docs = fields.Html('Documentation')
    # Numeric fields:
    sequence = fields.Integer('Sequence')
    perc_complete = fields.Float('% Complete', (3, 2))
    # Date fields:
    date_effective = fields.Date('Effective Date')
    date_changed = fields.Datetime('Last Changed')
    # Other fields:
    fold = fields...
