请更正代码，以便根据第一次选择加载第二个选择框。
type_id choice_id
fruit orange
fruit apple
drinks coffee
drinks tea
现在作为用户从选择框中选择水果的要求的一部分，其他选择框'选择'应该仅用橙色和苹果动态加载。当用户选择饮料作为类型时，应该加载咖啡和茶。

答案 0 :(得分：0)
选择字段有一个静态列表。在您的情况下，您应该在视图中使用带有widget ='selection'的many2one字段，以便您可以将一个字段的值传递给其他字段以进行过滤
例如，创建用于选择和类型的表。对于这些表，名称字段就足够了。在选择表中，为类型表添加一个many2one关系（比如type_id），这是一个必填字段。然后在new.base表中将这些字段添加为多个2字段（比如type_id和choice_id），并在字段<field name="type_id" widget='selection'/><field name="choice_id" domain="[('type_id','=',type_id)]" widget='selection'/>的视图中添加
