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] }
