Joins in ror

Rails
1

Hello Everyone,
I am having problems in implementing joins in ror. as I used

@users=User.joins('LEFT OUTER JOIN donations ON donations.user_id = users.id')

I also tried

@users=User.find_by_sql "select u.*, d.amount from users u left join donations d on u.id=d.user_id"

but since model name is user it only displays all records of users table
not a single record of donations table.
I want to display records of both tables users and donations with the
help of foreign key user_id in donations.

Thanks in advance

this way you don’t have to write queries.
To get a list of donations made by a user just make a call @user.donations

In addition see the Rails Guide on ActiveRecord Relationships for more
information.
