IS this the RAILS’s bug?

The way rails does it is the correct way. It will be reconstructed as  
an array in the params hash.

Looks like it. However, did you try in edge rails ? url\_for()  
generates expected link in edge for me. That’d be  
“users?names[]=aotianlong&names[]=ayowaya” in your case,
