dynamic - 如何在向导 openerp 中删除不可见字段的值

Question

我有一个很少领域的向导。最初它只显示一个选择字段，并根据选择的内容（我使用过 on_change），它会显示其他字段。

现在我在这种情况下遇到问题。用户最初选择“选择 1”并显示（比如说）姓名、地址、年龄并为该字段赋值，但用户决定将初始字段更改为“选择 2”，这将隐藏其他字段并显示字段主题，时间，导师。但是当我再次尝试选择“选择 1”时，这些值不会被删除。

我想删除隐藏字段的现有值。

你对如何做到这一点有任何想法吗？

谢谢，

Answer 1

您可以为选择类型字段创建 on_change 方法。

在该方法中，您可以根据选择字段值返回字段的 '' 值。

i.e if select=1 then return {'value':{'subject':'', 'time':'' , 'instructure': False}}
& if select=2 then return {'value':{'name':'', address:'' , 'age': 0}}

希望这会帮助你。

@anoma我还重载了调用 generate_xml() 的 field_view_get() ，其中不可见的字段属性也是动态的
