odoo 8 ParseError：“ValidateError Field（s）`arch`对约束失败：视图定义无效

Question

我正在尝试在Odoo 8中安装模块，并收到以下错误：

根据错误，模块的违规部分似乎是：

          </tree>
        </field>
      </page>
    </xpath>
  </field>
</record>

发现有大量类似错误的帖子，各种解决方案似乎都有所不同，但似乎没有一个对我有用。我该怎么办？

修改

清理第一个代码块并在第二个代码块中替换为完整错误 申请后

<xpath expr="/form/sheet/group[@string='General Properties']" position="after">

如下面的评论所示，我的错误如下：

Answer 1

错误显示在父视图（fleet_vehicle_form）中找不到您定义的路径。

您需要更正该xpath。

使用Odoo- v8.0时，

<xpath expr="/form/sheet/notebook/page[@string='General Properties']" position="after">

使用以下内容更改此xpath ...

<xpath expr="/form/sheet/group[@string='General Properties']" position="after">

父视图中没有notebook & page个标记（fleet_vehicle_form）。所以，这就是为什么它会给你错误。

Answer 2

查看继承

Odoo不是修改现有视图（通过覆盖它们），而是提供视图继承，其中子视图“扩展”视图应用于根视图之上，并且可以添加或删除其父视图中的内容。

扩展视图使用inherit_id字段引用其父级。

提示

匹配单个元素时，可以直接在要查找的元素上设置position属性。下面的两个遗产都会给出相同的结果。

<xpath expr="//field[@name='field_name']" position="after">
    <field name="new_field" />
</xpath>

<field name="field_name" position="after">
    <field name="new_field" />
</field>

页面无法在组后添加，您需要将其放在侧页或任何其他页面之后/之前。

<xpath expr="/form/sheet/group[@string='General Properties']" position="after">

将此行更新为

<page string="existing page string" position="after">
    <!-- add your page here -->
</page>

视图继承中非常重要的是 PRIORITY ，但似乎大多数都被忽略了。

<field name="priority" eval="50" />

优先级定义在可以使用父子层次结构的情况下执行创建视图的时间。

<record model="ir.ui.view" id="inherited_fleet_vehicle_form_view">
    <field name="name">Inherited Fleet Vehicle Form</field>
    <field name="model">fleet.vehicle</field>
    <field name="inherit_id" ref="fleet.fleet_vehicle_form"/>
    <field name="priority" eval="50" />
    <field name="arch" type="xml">
        <xpath expr="//label[@for='tag_ids']" position="before">
              <label for="internal_number" class="oe_edit_only"/>                      
            <h2>
                <field name="internal_number" class="oe_inline"/>       
            </h2>
             <label for="is_trailer" class="oe_edit_only"/>                 
             <field name="is_trailer" string="Is Trailer" help="Mark this if the vehicle is a trailer"/>
        </xpath>
        <sheet position="inside">
            <page string="Transport sales">
                <field name="sales_order_ids" readonly="1">
                    <tree editable="bottom">
                        <field name="sale_order_id"/>
                        <field name="sales_date"/>
                        <field name="partner_departure_id"/>
                        <field name="partner_destination_id"/>

                        <field name="return_date"/>
                    </tree>
                </field>

Answer 3

我得到了相同的错误“字段arch对约束失败：视图定义无效”，我使用了另一个模块中的字段，需要在中的'depends'中列出openerp .py文件。希望这有帮助。
