Hi everyone,
I am a newb. I have one question about following code:
def self.up
create_table :order_histories do |t|
t.column :order_id, :integer, :null => false
t.column :created_at, :timestamp
t.column :notes, :text
end
end
so, create_table is a method which takes the name of table
(order_histories) and a code block. I wonder what's the data type of
t?? where can I find it?

Couple of ways you could figure it out... the hack-ish way would be to add the following to your migration and then run it:
puts t.class
Or, look at the source for create_table in activerecord/lib/active_record/connection_adapters/abstract/schema_statements.rb
That says it's a TableDefinition object.
