In my opinion you are taking a wrong strategy for the create action. Just do

@user = User.new(params[:user])
@user.save

If you want to ensure that email is unique across users, use a Rails' validation like so:

class User
  #...
  validates_uniqueness_of :email
  #...
end

Your approach will modify an existing user with the same email during a create. Sounds wrong.

For more details, have a look at the create of a scaffolded controller.
