動態顯示具有不同域的多個one2many字段？

Question

我有一個與另一個模型（modelB）相關的one2many字段的模型（modelA），modelB中的一個字段是一個category字段，它是一個many2one字段。要求是爲每個類別顯示一個二十個字段。因此，如果有兩個類別分別命名爲'category1'和'category2'，則modelA的表單視圖應該有2個one2many字段，其中一個顯示category1的記錄，另一個顯示category2的記錄（可能可以使用域）。

例如，modelA和modelB具有以下結構。

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') 

我會如何實現用於MODELA一種形式的視圖，以便爲每個類別（其可以由用戶來添加，因此，可以有任意數量的類別中的）有一個單獨的one2many字段。

Answer 1

你在問什麼需要很多時間來給出一個很好的答案我認爲你需要嘗試的方式之一是覆蓋fields_view_get，因爲這是檢索視圖的方法，在這裏你可以改變arch字段添加一個costum場看看這個教程：

Tutorial for dynamic view

，但我認爲你將有一個問題，因爲即使當你把域在XML的one2many場，odoo不會過濾 在視圖上發生加載時的記錄：

<!-- 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)]"> 

但是當我這個字段添加到蟒蛇聲明

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

所以通過fields_view_get增加one2many場拱問題是容易的，但問題是filtring數據！

Answer 2

這在技術上是不可能的。因爲在同一視圖中不能有兩次相同的字段。

但是你可以創建一個特定的小部件來顯示你想要的東西。您如何在時間表視圖中查看（我的當前時間表菜單）。

這是一個創建小部件的小教程。 https://www.odoo.com/documentation/10.0/howtos/web.html#widgets-basics

這不是一個答案，但你能說動態視圖的教程示例： MODUL structur：

意見。XML：

我發現，您可以使用ORM方法甚至計算領域建立領域。我認爲創建一個小部件比較好，但是很高興知道文能夠創建成本領域。

希望這有助於你

注意我沒有爲個人記錄創建一個菜單，但你可以通過點擊在車上形式owner_id看風景，如果未顯示剛剛刷新的新one2many場頁。
