Sorting an array of objects in Ruby by object attribute?
I recommend using sort_by instead:
objects.sort_by {|obj| obj.attribute}
Especially if attribute may be calculated.
Or a more concise approach:
objects.sort_by(&:attribute)
Yes, using Array#sort! this is easy.
myarray.sort! { |a, b| a.attribute <=> b.attribute }
Ascending order :
objects_array.sort! { |a, b| a.attribute <=> b.attribute }
or
objects_array.sort_by{ |obj| obj.attribute }
Descending order :
objects_array.sort! { |a, b| b.attribute <=> a.attribute }
or
objects_array.sort_by{ |obj| obj.attribute }.reverse
