我想基于布尔字段隐藏one2many树视图中的字段

如果选中了布尔字段，则在下面的树视图中显示字段总数。

树视图属于class'account.invoice.line'，代码如下（布尔字段）：

class account_invoice_line(models.Model):
    _name = "account.invoice.line"
    _description = "Invoice Line"
    _order = "invoice_id,sequence,id"

    name = fields.Text(string='Description')
    tot_qty_bool = fields.Boolean(string='Total Quantity', default=False)
    tot_qty = fields.Float(string='Total Quantity')
    origin = fields.Char(string='Source Document',
        help="Reference of the document that produced this invoice.")
    sequence = fields.Integer(string='Sequence', default=10,
        help="Gives the sequence of this line when displaying the 
invoice.")
    invoice_id = fields.Many2one('account.invoice', string='Invoice 
Reference',
        ondelete='cascade', index=True)
    uos_id = fields.Many2one('product.uom', string='Unit of Measure',
        ondelete='set null', index=True)
    product_id = fields.Many2one('product.product', string='Product',
        ondelete='set null', index=True)
    account_id = fields.Many2one('account.account', string='Account',
        domain=[('type', 'not in', ['view', 'closed'])],
        default=_default_account,
        help="The income or expense account related to the selected 
product.")
    price_unit = fields.Float(string='Unit Price', required=True,
        digits= dp.get_precision('Product Price'),
        default=_default_price_unit)
    price_subtotal = fields.Float(string='Amount', digits= 
dp.get_precision('Account'),
        store=True, readonly=True, compute='_compute_price')
    quantity = fields.Float(string='Actual Quantity', digits= 
dp.get_precision('Product Unit of Measure'),
        required=True, default=1)
    discount = fields.Float(string='Discount (%)', digits= 
dp.get_precision('Discount'),
        default=0.0)
    invoice_line_tax_id = fields.Many2many('account.tax',
        'account_invoice_line_tax', 'invoice_line_id', 'tax_id',
        string='Taxes', domain=[('parent_id', '=', False)])
    account_analytic_id = fields.Many2one('account.analytic.account',
        string='Analytic Account')
    company_id = fields.Many2one('res.company', string='Company',
        related='invoice_id.company_id', store=True, readonly=True)
    partner_id = fields.Many2one('res.partner', string='Partner',
        related='invoice_id.partner_id', store=True, readonly=True)

和代码部分我在fields_view_get中尝试了类似的东西（没有成功）

def fields_view_get(self, view_id=None, view_type='form', 
toolbar=False, submenu=False):
        res = super(account_invoice_line, self).fields_view_get(
            view_id=view_id, view_type=view_type, toolbar=toolbar, 
submenu=submenu)
        if self._context.get('tot_qty_bool'):
            doc1 = etree.XML(res['arch'])
            for node in doc.xpath("//field[@name='tot_qty']"):
                if self._context['tot_qty_bool'] in ('False'):
                    node.set('invisible', '1')
                else:
                    node.set('invisible', '0')
            res['arch'] = etree.tostring(doc)
        return res

请指导我这样做的正确方法，或者让我知道是否有其他正确的方法可以实现相同目的。真的是一个很大的帮助。

当odoo呈现模型视图时，只有在初始渲染过程中才会调用

fields_view_get。因此，只有在呈现account.invoice.line视图时才能执行您尝试执行的操作。

尝试继承invoice_form视图并使用attrs隐藏tot_qty字段。 （您需要在树视图中添加tot_qty_bool字段）。

<record id="invoice_form_inherit" model="ir.ui.view">
  <field name="name">invoice.form.inherit</field>
  <field name="model">account.invoice</field>
  <field name="inherit_id" ref="account.invoice_form"/>
  <field name="arch" type="xml">
      <xpath expr="//tree/field[@name='name']" position="after">
            <field name='tot_qty_bool' invisible="True"/> 
            <field name='tot_qty' attrs="{'invisible':[('tot_qty_bool', '=', False)]}"/>
        </xpath>

  </field>
</record>

正如@macdelacruz已在评论中提及，请在树状视图定义中使用attrs和invisible。

我在Odoo V8 runbot上测试过类似的例子。

从原始时间表表单视图：

<field name="name" />

只需将其更改为：

<field name="name" attrs="{'invisible': [('unit_amount','=',0)]}"/>

保存，重新加载并尝试使用它。它正在工作。

如何动态隐藏one2many树视图中的列？
