字段基于父字段Odoo 8不可见

I need to invisible a column of one2many field based on parent field. By inheriting account.invoice model i have added a field inv_type. In account_invoice_line i need to make invisible field 'quantity' if inv_type = 'utility'.

我需要根据父字段隐藏一个one2many字段的列。通过继承account.invoice模型，我添加了一个字段inv_type。在account_invoice_line中，如果inv_type ='utility'，我需要创建不可见字段'quantity'。

I tried below code:

我尝试下面的代码：

XML：

<record id="ams_invoice_form" model="ir.ui.view">
        <field name="name">account.invoice.form</field>
        <field name="model">account.invoice</field>
        <field name="inherit_id" ref="account.invoice_form"></field>
        <field name="inherit_id" ref="ams.3e_invoice_form"></field>
        <field name="arch" type="xml">
            <xpath expr="//notebook/page/field/tree/field[@name='quantity']" position="replace">
                <field name="quantity"  attrs="{'invisible':[('parent.inv_type,'=','utility')]}" />
                <field name="consumed_unit"/>
                <field name="fixed_charge"/>
            </xpath>

        </field>
    </record>

Really complicated, as a suggestion you can use an attribute that applies in odoo 9:

真的很复杂，作为建议你可以使用适用于odoo 9的属性：

<record id="ams_invoice_form" model="ir.ui.view">
        <field name="name">account.invoice.form</field>
        <field name="model">account.invoice</field>
        <field name="inherit_id" ref="account.invoice_form"></field>
        <field name="inherit_id" ref="ams.3e_invoice_form"></field>
        <field name="arch" type="xml">
            <xpath expr="//notebook/page/field/tree/field[@name='quantity']" position="replace">
                <field name="quantity" invisible="context.get('ok_invisible', False)"/>
                <field name="consumed_unit"/>
                <field name="fixed_charge"/>
            </xpath>

        </field>
    </record>

In the invoicing module it has to affect the fields_view_get function, I understand that you want to hide the columns of the invoice product list so it must affect the account.invoice.line object:

在发票模块中，它必须影响fields_view_get函数，我知道您要隐藏发票产品列表的列，因此它必须影响account.invoice.line对象：

class AccountInvoiceLine(models.Model):

      _inherit = "account.invoice.line"

      @api.model
      def fields_view_get(self, view_id=None, view_type=False, toolbar=False, submenu=False):
          if self.invoice_id.inv_type == 'utility':
             self = self.with_context(ok_invisible=True)
          else:
             self = self.with_context(ok_invisible=False)

          return super(AccountInvoiceLine, self).fields_view_get(view_id=view_id, view_type=view_type, toolbar=toolbar, submenu=submenu)

In Odoo 8.0 I had to implement it a little bit others. It has the same logic in view but I had to use the fields_view_get method of sale.order and it is needed to load the order from its identifier:

在Odoo 8.0中，我不得不实施一些其他的。它在视图中具有相同的逻辑，但我必须使用sale.order的fields_view_get方法，并且需要从其标识符加载订单：

class SaleOrder(models.Model):
    _inherit = 'sale.order'

    @api.model
    def fields_view_get(self, view_id=None, view_type=False, toolbar=False,
                        submenu=False):
        order = False
        params = self.env.context.get('params', False)
        if params:
            order_id = params.get('id', False)
            if order_id:
                order = self.browse(order_id)

        if order and not order.is_agreement:
            self = self.with_context(hide_agreement_cols=False)

        result = super(SaleOrder, self).fields_view_get(
            view_id=view_id, view_type=view_type,
            toolbar=toolbar, submenu=submenu
        )
        return result
