Odoo 中工作流模型的状态

Question

我正在尝试为我的自定义模型实施 Odoo 发布工作流 'product_images.product_image'。

我的模型是这样的：

# product_images/models/models.py
# -*- coding: utf-8 -*-
from odoo import models, fields, api, tools

class PublishingStatus(models.Model):
    _name = 'product_images.publishing_status'
    _description = 'Publishing status'

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


class ProductImage(models.Model):
    _name = 'product_images.product_image'
    _description = 'Product image'

    name = fields.Char(string="Alternative text")
    product_id = fields.Many2one('product.product', string='Product', ondelete='set null', index=True)
    original_image = fields.Binary(string='Original image')

    @api.model
    def _get_default_state(self):
        return self.env['product_images.publishing_status'].search([['slug', '=', 'draft']])

    @api.model
    def _get_all_states(self, groups, domain, order):
        state_ids = self.env['product_images.publishing_status'].search([])
        return state_ids

    state_id = fields.Many2one(
        'product_images.publishing_status',
        string='Publishing status',
        default=_get_default_state,
        group_expand='_get_all_states',
    )

    @api.multi
    def action_set_to_draft(self):
        self.state_id = self.env['product_images.publishing_status'].search([['slug', '=', 'draft']])

    @api.multi
    def action_request_for_approval(self):
        self.state_id = self.env['product_images.publishing_status'].search([['slug', '=', 'pending']])

    @api.multi
    def action_approve(self):
        self.state_id = self.env['product_images.publishing_status'].search([['slug', '=', 'approved']])

    @api.multi
    def action_reject(self):
        self.state_id = self.env['product_images.publishing_status'].search([['slug', '=', 'rejected']])

然后我有一些发布状态的数据记录：

<!-- product_images/data/data.xml -->
<odoo>
    <data>
        <!-- explicit list view definition -->
        <record model="product_images.publishing_status" id="product_images.publishing_status_draft">
            <field name="name">Draft</field>
            <field name="slug">draft</field>
        </record>
        <record model="product_images.publishing_status" id="product_images.publishing_status_pending">
            <field name="name">Pending</field>
            <field name="slug">pending</field>
        </record>
        <record model="product_images.publishing_status" id="product_images.publishing_status_approved">
            <field name="name">Approved</field>
            <field name="slug">approved</field>
        </record>
        <record model="product_images.publishing_status" id="product_images.publishing_status_rejected">
            <field name="name">Rejected</field>
            <field name="slug">rejected</field>
        </record>
    </data>
</odoo>

我也有一些记录来创建一个允许在发布状态之间切换的工作流：

<odoo>
    <data>
        <record model="workflow" id="product_images.wkf_image_publishing">
            <field name="name">Product Image Publishing Workflow</field>
            <field name="osv">product_images.product_image</field>
            <field name="on_create">True</field>
        </record>

        <record model="workflow.activity" id="product_images.wkf_activity_draft">
            <field name="name">Draft</field>
            <field name="wkf_id" ref="product_images.wkf_image_publishing" />
            <field name="flow_start" eval="True" />
            <field name="kind">function</field>
            <field name="action">action_set_to_draft()</field>
        </record>
        <record model="workflow.activity" id="product_images.wkf_activity_pending">
            <field name="name">Pending</field>
            <field name="wkf_id" ref="product_images.wkf_image_publishing" />
            <field name="kind">function</field>
            <field name="action">action_request_for_approval()</field>
        </record>
        <record model="workflow.activity" id="product_images.wkf_activity_approved">
            <field name="name">Approved</field>
            <field name="wkf_id" ref="product_images.wkf_image_publishing" />
            <field name="flow_stop" eval="True" />
            <field name="kind">function</field>
            <field name="action">action_approve()</field>
        </record>
        <record model="workflow.activity" id="product_images.wkf_activity_rejected">
            <field name="name">Rejected</field>
            <field name="wkf_id" ref="product_images.wkf_image_publishing" />
            <field name="flow_stop" eval="True" />
            <field name="kind">function</field>
            <field name="action">action_reject()</field>
        </record>

        <record model="workflow.transition" id="product_images.wkf_transition_draft_to_pending">
            <field name="act_from" ref="product_images.wkf_activity_draft" />
            <field name="act_to" ref="product_images.wkf_activity_pending" />
            <field name="condition">name != "" and original_image != ""</field>
            <field name="signal">pending</field>
        </record>
        <record model="workflow.transition" id="product_images.wkf_transition_pending_to_draft">
            <field name="act_from" ref="product_images.wkf_activity_pending" />
            <field name="act_to" ref="product_images.wkf_activity_draft" />
            <field name="signal">draft</field>
        </record>
        <record model="workflow.transition" id="product_images.wkf_transition_pending_to_approved">
            <field name="act_from" ref="product_images.wkf_activity_pending" />
            <field name="act_to" ref="product_images.wkf_activity_approved" />
            <field name="signal">approve</field>
        </record>
        <record model="workflow.transition" id="product_images.wkf_transition_pending_to_rejected">
            <field name="act_from" ref="product_images.wkf_activity_pending" />
            <field name="act_to" ref="product_images.wkf_activity_rejected" />
            <field name="signal">reject</field>
        </record>
    </data>
</odoo>

现在是最棘手的部分！我需要一个带有按钮的表单来在工作流状态和显示当前活动状态的状态栏之间切换。这是我试过的：

    <record model="ir.ui.view" id="product_images.form">
        <field name="name">Product Image</field>
        <field name="model">product_images.product_image</field>
        <field name="arch" type="xml">
            <form>
                <header>
                    <!--
                    <button name="draft"
                            type="workflow"
                            string="Set to draft"
                            attrs="{'invisible': [('state_id.slug','not in',['pending'])]}"
                    />
                    <button name="pending"
                            type="workflow"
                            string="Request for approval"
                            attrs="{'invisible': [('state_id.slug','not in',['draft'])]}"
                    />
                    <button name="approve" 
                            type="workflow"
                            string="Approve"
                            attrs="{'invisible': [('state_id.slug','not in',['pending'])]}"
                            class="oe_highlight"
                    />
                    <button name="reject" 
                            type="workflow"
                            string="Reject"
                            attrs="{'invisible': [('state_id.slug','not in',['pending'])]}"
                            class="oe_highlight"
                    />
                    -->
                    <field name="state_id" widget="statusbar" />
                </header>

                <sheet>
                    <group>
                        <field name="product_id" />
                        <field name="name" string="Alternative text" />
                        <field name="original_image" widget="image" class="oe_avatar" />
                        <field name="state_id" />
                    </group>
                </sheet>
            </form>
        </field>
    </record>

我遇到的问题：

显示状态栏，但当前发布状态未激活
如果我取消注释按钮，它们会抛出有关域无效的错误：

Uncaught Error: Unknown field state_id.slug in domain [["state_id.slug","not in",["pending"]]]

我错过了什么？

Answer 1

在 domain 属性中，我们不能使用左侧的父字段。对于您的情况，我们需要添加相关字段。

例如：

class ProductImage(models.Model):
    _name = 'product_images.product_image'

    slug = fields.Char(related='state_id.slug', string='Slug', store=True)

在你的视图文件state_id之后放置slug字段

<field name="slug" invisible="1"/>

现在取消注释 <button> 代码。

之后，重启Odoo服务器并升级您的自定义模块。
