Divide array of objects by common parameters in Ruby

Question

I have an array of objects @objects and would like to split this into an array of arrays based on a parameter, ending up with an array where each entry is an array of objects all of which have object.property the same.

@objects = [obj1, obj2, obj3, obj4, obj5]
obj1.property = a
obj2.property = a
obj3.property = b
obj4.property = b
obj5.property = c
array = [[obj1, obj2,], [obj3, obj4], [obj5]]

Answer 1

@objects.group_by { |obj| obj.property }.values
