How to find record from an array of two dimensional array in rails 3?

ruby ruby-on-rails-3 multidimensional-array

my_array.select{ |user, flag| user.id == 2}

all users with true flag:

my_array.select{ |user, flag| flag }

or false:

my_array.select{ |user, flag| !flag }

ruby ruby-on-rails-3 multidimensional-array

You can do something like

[ [user1,true], [user2,true], [user3,false] ].select { |u| u.first.id == 2}

This will return only the records that have the user id equal to 2.

ruby ruby-on-rails-3 multidimensional-array

Same answer as @eugen, only syntax difference(and using detect to return single dimensional array instead of 2 dimensional array):

[ [user1,true], [user2,true], [user3,false] ].detect { |user, boolean| user.id == 2 }=> [user2, true]
