Ruby on Rails

Thanks for your answers. I already know cancancan, but it doesn't solve my issue. I'm looking for a way to use cancan to determine my strong parameters (see my examples), not cancan to use strong parameters.

Hello Rails World,

does anybody know a good solution for Strong Parameters in a Rails app authorized by Cancan (or a similar authorization gem)?

def user_params

  if current_user.admin?

    params.require(:user).permit!

  else

    params.require(:user).permit(:password, :password_confirmation)

  end

end

Now I want to do this the "Cancan way". My first idea looks strange to me:

def user_params

  if can? :edit_all_attributes, User

    params.require(:user).permit!

  elsif can? :edit_password, User

    params.require(:user).permit(:password, :password_confirmation)

  end

end

How would you realize the attribute level in Cancan? :edit_all_attributes and :edit_password scales very badly if more user roles and optional attributes are involved. It would be nice if allowed attributes are defined in Cancan's Ability class and used automatically to determine strong parameters.

Do you Cancan plugins or replacements that allow a more satisfying attribute level authorization and/or strong parameters integration?
