Question

考虑一下：

is_book_block

如果指定位置有足够的产品数量（isbn），请将文档状态更改为True，并将布尔字段state更改为class bsi_print_order(models.Model): _name = 'bsi.print.order' @api.model def create(self, vals): if vals.get('name', 'New') == 'New': vals['name'] = self.env['ir.sequence'].next_by_code('bsi.print.order') or '/' return super(bsi_print_order, self).create(vals) name = fields.Char('Reference', required=True, index=True, copy=False, readonly='True', default='New') order_lines = fields.One2many('bsi.print.order.lines', 'print_order', string="Order lines") book_block = fields.Boolean(string="Book Block", default=True) binding = fields.Boolean(string="Binding") edging = fields.Boolean(string="Edging") state = fields.Selection([ ('draft','Draft'), ('awaitingraw','Awaiting raw materials'), ('work_in_progress','Print in Progress'), ('delivered','Delivered'), ('cancel','Cancel'), ], string="State")。

is_book_block字段位于父模型上：

One2many order_lines field

class bsi_print_order_lines(models.Model): _name = 'bsi.print.order.lines' print_order = fields.Many2one('bsi.print.order', string="Print Order") isbn = fields.Many2one('product.product', string="ISBN", domain="[('is_isbn', '=', True)]") qty = fields.Integer(string="Quantity") consumed_qty = fields.Integer(string="Quantity consumed") remaining_qty = fields.Float(string="Remaining quantity") is_book_block = fields.Boolean(string="Is Book Block Done") is_binding = fields.Boolean(string="Is Binding Done") is_edging = fields.Boolean(string="Is Edging Done") isbns = fields.Many2one('worksheets.isbns', string="Worksheet ISBNS")字段位于子类is_binding上：

is_edging

还有其他两个字段state和is_book_block。

无论如何，知道一个足以弄清楚其他两个（我猜，大声笑）所以，因为True在父类上，它运作良好，记录的状态实际上发生了变化， order_lines没有语法错误，它应该更改为public class MyFirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService { @Override public void onCreate() { super.onCreate(); ShortcutBadger.applyCount(MyFirebaseMessagingService.this, 1); } }，但它没有，所以，我认为这是因为该方法在var Dog = React.createClass({ bark: function() { alert('bow'); }, render: function() { return (<div>Dog</div>); } });上循环，但它改变了一些东西仅限父类（bsi.production.order）。

有什么想法吗？

根据我的理解，is_book_block在行中循环时，每行都是一个记录，如果你想设置多于字段或只是改变那个字段，你就会调用write：

  # when you change just one field no need for write just 
  rec.state = 'work_in_progress' # is enough
  # because rec.state will trigger write method
  # but for more than one field use write to trigger it only one time
  # line is a record too you can call write also if you want
  line.is_book_block = True

有一件事从onchange装饰器中移除order_lines.is_book_block，因为你将触发对该方法的不定式调用：

  @api.onchange('order_lines')
