attr_accessible in rails 4

I am watching the intro workshop but using rails 4 and trying to see where things change. One thing that I noticed now is that while in rails 3, it gave an mass-assignment protect attributes error when trying to create an object by passing an hash value in, it doesn’t give the same error in my rails 4.

Where can I find more information about it? I did a google search but nothing comes up for this particularly.

Any help?

Hi Shankard,

This link has a good write up on mass-assignment: Mass Assignment, Rails, and You
