I would like to save a person's information like Education, Address, etc into database tables.
If I generate Person Table(with Education) using Scaffold - id is automatically generated as primary key.
I would like to generate another table called Address for the same person using Scaffold. How can I link the id of Address table to id of Person table?
You want person to have_many addresses -see the rails guide for more on associations http://guides.rubyonrails.org/association_basics.html#the-has-many-association
You can scaffold this by doing
Rails g scaffold Address person:references line1:string city:string etc
This will generate another model, Address, with a foreign key person_id to say which person it belongs to.
