activerecord

I have the following models

user

has_many :leave_balances

leave_balance

belongs_to :user
belongs_to :leave_type

leave_type

has_many :leave_balances

I want to output a table format showing user names and their balance by leave type. Not every user can have every balance i.e. outer joins required.

I'd like to see something like this:

Employee   Annual Leave   Sick Leave
Bob        10 
Fred                      9
Sara       12             15

I am unsure how to get this out as a single statement?

I am thinking something like User.joins(:leave_balances).joins(:leave_type)
