Sorting an array basedon two attributes of objects

ruby-talk
1

Hi all,
     I want to sort the objects of array based on two attributes.I want
sort an employee class based on his salary and name , so that if two
person has same salary it should be sorted with name.
     Lets say for example the employee objects has following name and
salary.

         name salary
           d 100
           c 200
           b 50
           a 100

     so in this case the result which i expect is

         name salary
           c 50
           a 100
           d 100
           b 200

  Note:In the above example for salary 100 the sorting is done
alphabetically, but initially(before sorting) 'd' came first and then
'a' came.so basically i want to sort the array with more than one order.
  Can any one help me to solve it ??

Is this what you had in mind?

sorted_employees = employees.sort_by { |e| [ e.salary, e.name ] }

I think you could try this:

results = person.sort_by { |p| [p.salary, p.name] }

That should sort by salary first, then name.

Try this: employees.sort_by { |employee| [employee.salary,
employee.name] }
