odoo类型错误:在继承的模型上混合苹果和橙子

Question

我有odoo 12和模块合同管理 - 定期"，我正在编写一个模块来创建一个名为"leases"的模型，该模型使用_inherit从account.analytic.account继承。 窗体视图继承自contract.account_analytic_account_sale_form。它运行良好，除了当我尝试从发票行添加产品时，出现错误

TypeError: Mixing apples and oranges: account.analytic.account(<odoo.models.NewId object at 0x07736650>,) & pmtest.leases(<odoo.models.NewId object at 0x07736650>,)

该模型为：

class leases(models.Model):
    _name = 'pmtest.leases'
    _description = 'Leases - inherit from Contracts'
    _inherit = 'account.analytic.account'
    lease

名称 = 字段。字符((

视图是

<record id="pmtest_leases_form" model="ir.ui.view">
    <field name="name">pmtest.leases.form</field>
    <field name="model">pmtest.leases</field>
    <field name="inherit_id" ref="contract.account_analytic_account_sale_form"/>
    <field name="mode">primary</field>
    <field name="priority" eval="20"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='partner_id']" position="after">
                <field name="leasename" string="Lease Name"/>
        </xpath>
    </field>
</record>

完整堆栈跟踪如下：

Answer 1

我认为问题出在属性_name上。

尝试删除_name属性。

不同之处在于，如果添加_name，则会在数据库中创建一个新表。如果仅添加 _inherit 属性，则创建的字段将添加到名为 _inherit 属性的表中。

如果您看到，错误表明您无法将"account.analytic.account"模型与"pmtest.leases"模型进行比较，因为您使用_name定义了不同的模型。
