以一个例子开头
* To-do 向导
# 配置文件
__openerp_.py:
{ 'name': 'To-do Tasks Management Assistant',
'description': 'Mass edit your To-Do backlog.',
'author': 'Daniel Reis',
'depends': ['todo_user'],
'data': ['todo_wizard_view.xml'], }
__init__.py:
from . import todo_wizard_model
# 模型 todo_wizard_model.py
# -*- coding: utf-8 -*-
from openerp import models, fields, api
from openerp import exceptions # will be used in the code
import logging
_logger = logging.getLogger(__name__)
class TodoWizard(models.TransientModel):
_name = 'todo.wizard'
task_ids = fields.Many2many('todo.task', string='Tasks')
new_deadline = fields.Date('Deadline to Set')
new_user_id = fields.Many2one( 'res.users', string='Responsible to Set')
@api.multi
def do_mass_update(self):
self.ensure_one()
if not (self.new_deadline or self.new_user_id):
raise exceptions.ValidationError('No data to update!')
# else:
_logger.debug('Mass update on Todo Tasks %s', self.task_ids.ids)
if self.new_deadline:
self.task_ids.write({'date_deadline': self.new_deadline})
if self.new_user_id:
self.task_ids.write({'user_id': self.new_user_id.id})
return True
@说明几点：
@ 引入了日志功能，记录的级别如下4级
_logger.debug('A DEBUG message')
_logger.info('An INFO message')
_logger.warning('A WARNING message')
_logger.error('An ERROR message')
# 表单 todo_wizard_view.xml
To-do Task Wizard
todo.wizard
name="To-Do Tasks Wizard"
src_model="todo.task" res_model="todo.wizard"
view_mode="form" target="new" multi="True"/>
@说明：有一个批量更新的逻辑 do_mass_update
