Question

如何隐藏many2one字段中的所有项目。我想只允许用户创建新的付款条件。我们在account中的account_invoice.py模块中包含此代码：

class AccountInvoice(models.Model):
    _name = "account.invoice"
    payment_term_id = fields.Many2one('account.payment.term', 
                                       string='Payment Terms', 
                                       oldname='payment_term',
                                       readonly=True, 
                                       states={'draft': [('readonly', False)]})

在account_invoice_view.xml我们有：

<field name="payment_term_id" 
       options="{'no_create': True}" 
       attrs="{'invisible': [('payment_term_id','=',False)]}"/>

我尝试了这段代码{'no_open':True}，但它没有用。

如果要隐藏列表中的所有元素，请尝试添加始终为False的域：

<field name="id" />
<field name="payment_term_id" 
       domain="[('id', '=', -1)]"
       attrs="{'invisible': [('payment_term_id','=',False)]}"/>

options="{'no_create': True}"如果我理解的话，你会得到你想要的反面

我认为你会发现这个解决方案对你有好处：

建议在模型中添加一个字段，此字段为many2many字段包含在当前记录中创建的payment_term_id列表。

 # this field is for technical purpose 
 create_payment_terms_ids = fields.Many2many(co_model='account.payment.term',
                                             relation='created_payment_rel',
                                             column1= 'invoice_id',
                                             column2= 'paymen_id',
                                             string='Created payment terms')

在此之后使用onchange方法来跟踪创建的付款并添加新的付款此字段的付款条件

@api.onchange('payment_term_id')
def onchange_payment_terms(self):
    """ keep track of created payment from the current
        invoice and show only them in drop down list."""
    if self.payment_term_id:
        # keep list of old ids here
        payment_ids = self.create_payment_terms_ids and self.create_payment_terms_ids.ids or []
        # check if list payment is empty this means that this is the first created payment
        # second check if the selected payment is a new payment that is created 
        # if one of the two is true add the selected value to the list of payment
        if not self.create_payment_terms_ids or self.payment_term_id.id not in payment_ids:
            payment_ids.append(self.payment_term_id.id)
            self.create_payment_terms_ids = [(4, self.payment_term_id.id)]

        # if list is not empty we change the domain to show only payment that exist in the list
        # else we use a special domain to show empty set.
        domain = payment_ids and [('payment_term_id', 'in', payment_ids)] or [('id', '=', -1)]
        return {'domain': {'payment_term_id': domain}}

在您的视图中添加新字段visible = "1"您不是用户可以看到它的值。你需要将它放在视图中，因为你需要它在onchange事件中的值，如果你没有把它放在你的many2many字段将永远是空的。

       <field name="create_payment_terms_ids" invisible="1"/>

并删除options="{'no_create':False}"这将删除下拉列表中的创建和编辑选项，但您不希望这样。

注意：当您处于开发阶段时，请移除invisible="1"以查看many2many字段是否包含您拥有的付款列表创建。

如何仅允许在many2one字段中创建选项
