在模型 2 的树视图中显示模型 1 的字段

Question

我想显示 payroll.adjustment.lines 中的字段，即employee_id，并从 payroll.adjustment 模型的树视图中显示它。是否可以？他们有关系。

来自 payroll.adjustment 模型

adjustment_lines = 
fields.One2many('payroll.adjustment.lines','adj_id',string="Adjustment 
lines")

来自 payroll.adjustment.lines 模型

adj_id = fields.Many2one('payroll.adjustment',string="Payroll 
Adjustment",ondelete='cascade')

在我的 xml 中

<record id="payroll_adjustment_tree_view" model="ir.ui.view">
        <field name="name">payroll_adjustment.tree</field>
        <field name="model">payroll.adjustment</field>
        <field name="arch" type="xml">
            <tree string="Payroll Adjustment" colors="red:state == 
            'void';green:state == 'draft';blue:state=='confirm'">
                <field name="doc_num"/>
                <field name="company_id"/>
                <field name="adjustment_lines"/>
                <field name="date_from"/>
                <field name="date_to"/>
                <field name="state"/>
            </tree>
        </field>
    </record>

<field name="adjustment_lines"/>

只显示（2 条记录）而不是员工姓名。请帮帮我。谢谢

我尝试了下面的答案，这就是结果。员工姓名显示为假

这是我的树视图，我从行中调用该字段并从我的 payroll.adjustment 模型将其显示到树视图。

这是我的树视图的输出，它只显示（记录）

当您覆盖模型payroll.adjustment.line 的name_get() 方法时，它可以工作。以下代码示例希望是自我解释和您案例的一般示例：

from odoo import models, fields, api


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

    another_model_ids = fields.One2Many(
        comodel_name="another.model", inverse="my_model_id",
        string="Another Model Entries")


class AnotherModel(models.Model):
    _name = "another.model"

    my_model_id = fields.Many2One(
        comodel_name="my.model", string="My Model")
    number = fields.Integer(string="A Number")
    yet_another_model_id = fields.Many2One(
        comodel_name="yet.another.model", string="Yet Another Model")

    @api.multi
    def name_get(self):
        # with context flags you can implement multiple
        # possibilities of name generation
        # best example: res.partner
        res = []
        for another_model in self:
            res.append((another_model.id, "{} {}".format(
                another_model.number,
                another_model.yet_another_model_id.name)))
        return res


class YetAnotherModel(models.Model):
    _name = "yet.another.model"

    name = fields.Char(string="Name")

my.model 将是您的 payroll.adjustment、another.model 线路，yet.another.model 将是 hr.employee employee_id 后面的模型。
