如何从Odoo的弹出窗口中获取父窗体的字段？

I have a form with a One2many field. From this field you can add elements, if you do this, a pop-up is opened. I would like to know how to get a field which was in the parent form in this pop-up.

我有一个One2many字段的表单。在此字段中，您可以添加元素，如果执行此操作，则会打开一个弹出窗口。我想知道如何在弹出窗口中获取父窗体中的字段。

For example:

例如：

The parent form (model my.parent.model) has a field named partner_id. The pop-up (model my.child.model) has a field named product_id. In my.child.model I added a function which is called when product_id changes (@api.onchange('product_id')). In this function I want to get the partner_id selected in the parent form.

父表单（模型my.parent.model）有一个名为partner_id的字段。弹出窗口（模型my.child.model）有一个名为product_id的字段。在my.child.model中，我添加了一个在product_id更改时调用的函数（@ api.onchange（'product_id'））。在这个函数中，我想在父表单中选择partner_id。

To do this, I added this to product_id in the XML view:

为此，我在XML视图中将其添加到product_id：

<field name="product_id" context="{'partner_id':parent.partner_id}" />

In the onchange function, if there is not a selected partner, I raise an exception. When the pop-up is opened, this exception always raises, despite having a partner selected. But then, when I select any product, it works perfect.

在onchange函数中，如果没有选定的伙伴，我会引发异常。打开弹出窗口时，尽管选择了合作伙伴，但此异常总是会提升。但是，当我选择任何产品时，它都是完美的。

The problem is that the onchange function is triggered when the pop-up is opened, and in this case the context does not have the variable partner_id (as if it hadn't had enough time to get it).

问题是打开弹出窗口时会触发onchange函数，在这种情况下，上下文没有变量partner_id（就好像它没有足够的时间来获取它）。

This problem did not happened in version 7, because in this version you had to pass variables to the onchange and you can include the partner_id there, but now, in version 8, how can I manage this?

这个问题在版本7中没有发生，因为在这个版本中你必须将变量传递给onchange，你可以在那里包含partner_id，但现在，在版本8中，我该如何管理？

Thank you in advance!

先谢谢你！

Ok, I wasted a lot of time looking for a solution without adding new fields to the model, and I've found a solution just one minute after asking my question.

好吧，我浪费了很多时间寻找解决方案，而没有在模型中添加新字段，我在问我的问题后一分钟就找到了解决方案。

I had to add a context too to the One2many field of the parent form:

我不得不在父窗体的One2many字段中添加一个上下文：

<field name="order_line" position="attributes">
   <attribute name="widget">"one2many_list"</attribute>
   <attribute name="context">"{'partner_id': partner_id}"</attribute>
</field>

Now it works when the pop-up is opened!

现在它在弹出窗口打开时有效！
