动态显示具有不同域的多个one2many字段？

Question

我有一个与另一个模型（modelB）相关的one2many字段的模型（modelA），modelB中的一个字段是一个category字段，它是一个many2one字段。要求是为每个类别显示一个二十个字段。因此，如果有两个类别分别命名为'category1'和'category2'，则modelA的表单视图应该有2个one2many字段，其中一个显示category1的记录，另一个显示category2的记录（可能可以使用域）。

例如，modelA和modelB具有以下结构。

class classA(models.Model): 
    _name = 'modelA' 

    modelA_one2manyfield = fields.One2many('modelB', 'modelB_many2onefield') 

class classB(models.Model): 
    _name = 'modelB' 

    name = fields.Char() 
    category = fields.Many2one('modelC') 
    modelB_many2onefield = fields.Many2one('modelA') 

我会如何实现用于MODELA一种形式的视图，以便为每个类别（其可以由用户来添加，因此，可以有任意数量的类别中的）有一个单独的one2many字段。

Answer 1

你在问什么需要很多时间来给出一个很好的答案我认为你需要尝试的方式之一是覆盖fields_view_get，因为这是检索视图的方法，在这里你可以改变arch字段添加一个costum场看看这个教程：

Tutorial for dynamic view

，但我认为你将有一个问题，因为即使当你把域在XML的one2many场，odoo不会过滤 在视图上发生加载时的记录：

<!-- here all record are shown but the expected behavior is the one2many should be empty --> 
<field name="one2many_field_name" readonly="1" nolabel="1" domain="[('id', '=', False)]"> 

但是当我这个字段添加到蟒蛇声明

# here no record will be shown on the view and that's what was expected 
one2many_field_name = fields.One2many(..., domain=[('id', '=', False)]) 

所以通过fields_view_get增加one2many场拱问题是容易的，但问题是filtring数据！

Answer 2

这在技术上是不可能的。因为在同一视图中不能有两次相同的字段。

但是你可以创建一个特定的小部件来显示你想要的东西。您如何在时间表视图中查看（我的当前时间表菜单）。

这是一个创建小部件的小教程。 https://www.odoo.com/documentation/10.0/howtos/web.html#widgets-basics

这不是一个答案，但你能说动态视图的教程示例： MODUL structur：

我发现，您可以使用ORM方法甚至计算领域建立领域。我认为创建一个小部件比较好，但是很高兴知道文能够创建成本领域。

希望这有助于你

注意我没有为个人记录创建一个菜单，但你可以通过点击在车上形式owner_id看风景，如果未显示刚刚刷新的新one2many场页。
