Rails是否在数据库中存储数据关系？
[英]Does rails store data relationships in the database?
问题描述
When using relationships in rails are they stored in the database so all foreign keys are stored in the tables and such like or are all relationships controlled via the software? 
在rails中使用关系时，它们是否存储在数据库中，因此所有外键都存储在表中，诸如此类，还是所有关系都通过软件控制？

The foreign keys are stored in the tables. 外键存储在表中。 The has_many and belongs_to declarations in the models are only there to create the attributes used to access the relationships. 模型中的has_many和belongs_to声明仅用于创建用于访问关系的属性。
