Hi
I am not clear about how to use INNER JOINS and IN(…) sub query in
rails. Is there a good tutorial which helps newbies step by step ?
I have a
model Library
model Authors
model Fictions
The relation maybe explained as:
Library has many fiction books
authors have many fictions
The authors table has information like full name, period of life,
country etc.
In that case, I want to select fictions from library, where the authors
are from countries US and FRANCE
Thanks
R
