Odoo 10选择字段值

您可以通过以下方式执行此操作:

self._fields['your_field']._desription_selection(self.env)

如果您只需要可能的值,可以使用 get_values 方法

self._fields['your_field'].get_values(self.env)

class BaseSelectionType(object):
    """ Base abstract class """

    values = None

    @classmethod
    def get_selection(cls):
        return [(x, cls.values[x]) for x in sorted(cls.values)]

    @classmethod
    def get_value(cls, _id):
        return cls.values.get(_id, False)


class StateType(BaseSelectionType):
    """ Your selection """
    NEW = 1
    IN_PROGRESS = 2
    FINISHED = 3

    values = {
        NEW: 'New',
        IN_PROGRESS: 'In Progress',
        FINISHED: 'Finished'
    }

你可以在任何地方使用这个类,只需导入它。

state = fields.Selection(StateType.get_selection(), 'State')

在代码中使用它们真的很方便。例如,如果您想在特定状态下执行某些操作:

if self.state == StateType.NEW:
    # do your code ...

from datetime import datetime
from odoo import models, fields


class MyModel(models.Model):
    _name = 'my.model'

    def month_selection(self):
        return [(1, 'Month1'), (2, 'Month2')]

    def compute_default_value(self):
        selection = self.month_selection()
        # do whatever you want here

    month = fields.Selection(
        selection=month_selection, string='Month',
        default=datetime.now().month, required=True)
