Question

我正在学习如何在OpenERP v7上开发模块。在我尝试添加向导之前一切正常：OpenERP将不接受我的View架构，我无法弄清楚原因！

模块架构是：

_ init.py _ （我导入module.py和向导）
_ openerp.py _ （依赖项：Base; data：view / view.xml; wizard / wizard.xml）
module.py （我已经获得了主要代码，一切正常）
view / view.xml （主视图与主代码一致，没问题）
向导/ _ init.py _ （导入向导）
向导/ wizard.py （下面的代码）
向导/ wizard.xml （下面的代码）

这是wizard.py文件：

# -*- coding: utf-8 -*-
from openerp.osv import fields, osv

class idea_wizard(osv.TransientModel):
    _name = 'idea.wizard'
    _columns = {
                'idea_age': fields.integer('Age'),
                }

这是wizard.xml文件：

<?xml version="1.0"?>
<openerp>
    <data>
        <!-- Idea Category Form View -->
        <record model="ir.ui.view" id="view_idea_wizard_form">
            <field name="name">idea.wizard.form</field>
            <field name="model">idea.wizard</field>
            <field name="arch" type="xml">
                <form string="Cleanup" version="7.0">
                    <field name="idea_age"/>
                </form>
            </field>
        </record>
    </data>
</openerp>

目前这一切都是基本的，但我希望它有效，所以我可以在它上面......

这是服务器回溯：

  File "/usr/lib/pymodules/python2.7/openerp/addons/base/ir/ir_model.py", line 967, in _update

raise except_orm('ValidateError', '\n'.join(error_msgs)) except_orm: ('ValidateError', u'Error occurred while validating the field(s) arch: Invalid XML for View Architecture!')

如果我清空wizard.xml文件中的“arch”标记，则服务器不会引发任何错误。但我无法理解我的架构有什么问题。

感谢您的帮助：）

简短回答

确保使用utf-8编码保存XML文件。在xml定义中添加encoding属性：

 <?xml version="1.0" encoding="utf-8"?>

希望这有帮助。

一般来说，OpenERP中的数据验证主要通过每个模型的_constraints属性中设置的方法来处理。在您的情况下，您在尝试创建新的ir.ui.view对象时遇到错误。查看base/ir/ir_ui>view.py文件，您可以看到以下内容：

_constraints = [
    (_check_xml, 'Invalid XML for View Architecture!', ['arch'])
]

这里我们只定义了一个约束，并通过_check_xml方法进行评估。看看这种方法，您可以看到除了XML本身的有效性之外，还进行了编码测试。 OpenERP 6.0中不存在此测试。这意味着您的视图可能会在OpenERP 6.0下正确呈现。

如果您愿意，可以通过在__check_xml类的view方法中添加断点来进一步调查。

更改模型名称意味着给出要放置它的类的名称

<field name="model">test.wizard</field>
