在 OpenERP 7.0 中设置向导需要帮助

Question

我正在尝试实现一个将更新表单的向导（如果可能，向工作流发送信号以更改对象的状态，但这将在以后进行）。我一直在尝试，但我做错了，因为我遇到了这个烦人的错误！

ValueError：系统中当前没有定义这样的外部ID：processos_uc.reformulate_generic_request_wizard

我在“wizard”文件夹中有这两个文件： 重构向导.py：

from openerp.osv import osv
from openerp.osv import fields
from openerp.tools.translate import _

class ref_generic_request(osv.osv_memory):
    _name='ref.generic.request'

    _columns = {
        'reformulation_info': fields.text('Reformulation instructions', help='Instructions for the requestor justification the reformulation needs'),
            }

        def save_info(self, cr, uid, ids, context=None):
            if 'active_id' in context:
                info=self.browse(cr,uid,ids)[0].reformulation_info
                self.pool.get('generic.request').write(cr,uid,context['active_id'],
                                                     {'reformulation_info' : reformulation_info})
            return {
                    'type': 'ir.actions.act_window_close',
             }
    ref_generic_request()

reformulate_wizard.xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <record id="view_reformulate_generic_request_wizard" model="ir.ui.view">
            <field name="name">reformulate_generic_request_wizard.form</field>
            <field name="model">ref.generic.request</field>
            <field name="type">form</field>
            <field name="arch" type="xml">

                        <field name="reformulation_info" string="Reformulation info"/>
                        <newline/>
                    </group>
                    <separator string="" colspan="4" />
                    <group colspan="4" col="6">
                        <button  icon="gtk-cancel" special="cancel" string="Cancel"/>
                        <button  icon="gtk-ok" name="save_info" string="Send to reformulation" type="object" />
                    </group>
               </form>
            </field>
        </record>
        <record id="action_reformulate_generic_request" model="ir.actions.act_window">
            <field name="name">Reformulate Request</field>
            <field name="type">ir.actions.act_window</field>
            <field name="res_model">ref.generic.request</field>
            <field name="view_type">form</field>
            <field name="view_mode">form</field>
            <field name="view_id" ref="view_reformulate_generic_request_wizard"/>
            <field name="target">new</field>
        </record>

        <act_window id="action_reformulate_generic_request"
                name="Reformulate Request"
                res_model="generic.request"
                view_mode="form"
                target="new"
        />

    </data>
</openerp>

我并没有忘记其中带有“import reformulate_wizard”的__init__.py。

我正在像这样从我的 xml 视图调用向导（我猜这就是我得到错误的地方）：

<button  name="%(reformulate_generic_request_wizard)d" string="Button that calls wizard" type="object" />

在我的基本文件夹中，我正在导入__init__.py 中的向导文件夹：

import parecer
import pedido_generico
import tracing
import wizard

这是我的__openerp__.py 的内容（错误可能来自我加载东西的顺序）：

    'version': '0.1',
    'category': 'Tools',
    'description': """

             ],
    'installable': True,
    'images': [],
}

这是来自服务器日志的错误消息。

非常欢迎任何帮助！

Answer 1

错误消息告诉您问题出在哪里：您使用的 ID reformulate_generic_request_wizard 未在任何地方声明。

您的按钮应指向操作的 ID，action_reformulate_generic_request_wizard。

那么，试试这个：

<button  name="%(action_reformulate_generic_request_wizard)d" string="Button that calls wizard" type="object" />
