Ruby on Rails Tutorial” by Michael Hartl Ch 10 - undefined method `rest_digest=' for #0x007f3c04f08e20>

I need some help. The problem is when I try submitting an email to reset a password, I get the following error.

Application trace gives the following

app/models/user.rb:57:in create_reset_digest' app/controllers/password_resets_controller.rb:8:increate'

Request

Parameters:

{"utf8"=>"✓", "authenticity_token"=>"/jhl+HQLT42IZLH2ashW6y2fpSiUY+htnOSq4oQPeUTrkHDbaj2IvLYEmt5209E7BJV07nJK/1PH+lE1CkUgUw==", "password_reset"=>"[FILTERED]", "commit"=>"Submit"}
