sorting an array basedon two attributes of objects

[senthil]

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 ??

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

Kind regards,

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.
