Odoo - 初始化函数不工作

Question

我在示例模块中工作，我正在创建一个视图，我想在其中显示基于条件和来自多个模型的记录。已经在创建中。

Pending Accounts

class PendingAccounts(models.Model):
    _name = 'amgl.pending_accounts'
    _description = 'Pending Account'

    name = fields.Char()
    first_name = fields.Char(string="First Name")
    last_name = fields.Char(string="Last Name")
    quantity_expected = fields.Float(string="Quantity Expected")
    quantity_received = fields.Float(string="Quantity Received")
    possible_reason = fields.Many2one('amgl.product_reason',string='Possible Reason')
    possible_solution = fields.Many2one('amgl.product_solution', string='Possible Solution')
    notes = fields.Html(string='Notes')

    @api.model_cr
    def init(self):
        tools.drop_view_if_exists(self._cr, 'pending_accounts')
        self._cr.execute("""
            CREATE VIEW pending_accounts AS (
                SELECT c.name AS first_name,
                c.last_name AS last_name,
                o.total_received_qty AS quantity_received,
                o.total_qty AS quantity_expected
                FROM amgl_order AS o
                INNER JOIN amgl_customer AS c ON c.id = o.customer_id
                WHERE o.is_pending = True
            )""")

Pending Accounts View

</odoo>

所以我创建了一个模型并添加了查询以在模型的 init 方法中获取所有这些记录。但它没有在树 view.I 中显示任何记录，也没有在 pgadmin 中的查询运行中显示，并且有一条记录针对此查询，如附件所示。

我现在面临以下错误，

Answer 1

使用_auto=False执行init()方法。

是否应该创建数据库table（默认值：True）

如果设置为 False，覆盖 init() 以创建数据库 table。

编辑

在这种情况下，首先我们需要从数据库中永久删除 table。转到您的终端并按照以下命令操作：

sudo su postgres
psql <YourDatabaseName>
DROP TABLE amgl_pending_accounts CASCADE;
\q

现在刷新网络浏览器并升级模块。

Answer 2

如果你定义了 _name = 'amgl.pending.acounts'

试试这个

odoo 预计数据库中 table 的名称是：amgl_pending_accounts 试试这个。只需了解 (.) 将是 table 名称中的 (_)。

class PendingAccounts(models.Model):
            _name = 'amgl.pending.accounts'
            _description = 'Pending Account'
                        _auto = False

            name = fields.Char()
            first_name = fields.Char(string="First Name")
            last_name = fields.Char(string="Last Name")
            quantity_expected = fields.Float(string="Quantity Expected")
            quantity_received = fields.Float(string="Quantity Received")
            possible_reason = fields.Many2one('amgl.product_reason',string='Possible Reason')
            possible_solution = fields.Many2one('amgl.product_solution', string='Possible Solution')
            notes = fields.Html(string='Notes')

            @api.model_cr
            def init(self):
                tools.drop_view_if_exists(self._cr, 'pending_accounts')
                self._cr.execute("""
                    CREATE VIEW amgl_pending_accounts AS (

                        SELECT 
                        -- by default view expect the id columns to exists.
                        row_number() OVER () AS id,
                        c.name AS first_name,
                        c.last_name AS last_name,
                        o.total_received_qty AS quantity_received,
                        o.total_qty AS quantity_expected
                        FROM amgl_order AS o
                        INNER JOIN amgl_customer AS c ON c.id = o.customer_id
                        WHERE o.is_pending = True

Answer 3

您可以使用以下方法完成。

class PendingAccounts(models.Model):
    _name = 'amgl.pending_accounts'
    _description = 'Pending Account'
    _auto=False

    name = fields.Char()
    first_name = fields.Char(string="First Name")
    last_name = fields.Char(string="Last Name")
    quantity_expected = fields.Float(string="Quantity Expected")
    quantity_received = fields.Float(string="Quantity Received")
    possible_reason = fields.Many2one('amgl.product_reason',string='Possible Reason')
    possible_solution = fields.Many2one('amgl.product_solution', string='Possible Solution')
    notes = fields.Html(string='Notes')

    @api.model_cr
    def init(self):
        tools.drop_view_if_exists(self._cr, 'amgl_pending_accounts')
        self._cr.execute("""
            CREATE VIEW amgl_pending_accounts AS (
                SELECT                 
                min(o.id) as id,
                c.name AS first_name,
                c.last_name AS last_name,

                sum(o.total_received_qty) AS quantity_received,
                sum(o.total_qty) AS quantity_expected
                FROM amgl_order AS o
                INNER JOIN amgl_customer AS c ON c.id = o.customer_id
                WHERE o.is_pending = True
                Group By c.name,c.last_name
            )""")

_auto=False : Determines whether a corresponding PostgreSQL table must be generated automatically from the object. Setting _auto to False can be useful in case of OpenERP objects generated from PostgreSQL views. See the "Reporting From PostgreSQL Views" section for more details.

You must take min(o.id) as id in select query other wise it will give you Error.

Your view name & table name must be equal amgl_pending_accounts .

Update your query and add missing fields by joining those tables, then your error will be fixed.

这可能对您有所帮助。

Answer 4

在您的 select 查询中添加此行将解决问题：

Select row_number() OVER () as id , customer_id .................. 和在你的模型中添加 customer_id = fields.Many2one(amgl_customer,'customer')
