填充 Many2many 字段 (odoo 8)

Question

我做了什么：

我有一个模块

myfield = fields.Many2one('res.partner', string="Graduate", domain=[('is_graduated', '=', True)])

然后我有另一个 class 和

_inherit = 'res.partner'
is_graduated = fields.Boolean("Graduated before?", default=False)
graduations = fields.Many2many('my_module.courses', string="Graduation courses")

我得到的是：

myfield 工作正常，但 graduations 字段为空。如果您编辑 user 1 配置文件，您可以使用 Add item 将条目添加到 graduation 字段，但我需要它自动填充。

我的期望：

我希望当您打开 user 1 配置文件时，myfield 设置为 user 1 的每条记录都将在字段 graduations 中可见。当我创建记录并将 myfield 值设置为 user 1 时，该记录必须在字段 graduations 的 user 1 配置文件中可见。如何实现？

Answer 1

您需要为 myfield 使用 onchange method，然后您需要在其中填写 graduations 字段，如下所示：

@api.onchange('myfield'):
def _onchange_myfield(self):
    #fill graduations field here...
    ...

Answer 2

你可以这样实现。

例如：

@api.one
@api.depends(
      #here you may define your depend field name
)
def _set_graduations(self):
    #here comes your logic which will collect ids
    #and than return it with self.field_name like

    self.graduations = [list_of_ids]


graduations = fields.Many2many('my_module.courses', string='Payments',
                                compute='_set_graduations')

如果您不想使用 @api.depends，您可以使用 @api.multi。作为参考，您可以查看 account 模块和 account_invoice.py 文件。

Answer 3

user_rel_ids = fields.Many2many(comodel_name='course', 关系='user_course_rel', column1='user_id', column2='course_id')

或

user_rel_id = fields.Many2many('course')

用于填充数据（用于添加新关系）

user_rel_id = [(4,course_id)]

根据http://odoo4u.blogspot.com/2014/10/orm-methods.html，它说： class 的文档中提供了完整的选项列表。同样的事情将适用于 one2many

For a many2many and one2many field, a list of tuples is expected. Here is the list of the tuple that is accepted, with the corresponding semantics:

(0, 0, { values }) link to a new record that needs to be created with the given values dictionary

(1, ID, { values }) update the linked record with id = ID (write values on it)

(2, ID) remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)

(3, ID) cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)

(4, ID) link to existing record with id = ID (adds a relationship)

(5) unlink all (like using (3, ID) for all linked records)

(6, 0, [IDs]) replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs)

Answer 4

_inherit = 'crm.phonecall'    
alarm_ids = fields.Many2many('calendar.alarm',string="Reminders") 
 set the alarm_ids of calendar.event model in create method of crm phonecall...
 alarm_ids = [(6,0,self.alarm_ids.ids)] 

_inherit = 'calendar.event'
 alarm_ids = fields.Many2many('calendar.alarm',string="Reminders")
