Impossible to reset protected field to nil about strongbox HOT 9 CLOSED

All data is encrypted, nil, blank, or otherwise, to avoid revealing anything about the data. If you which to store an unencrypted nil (or anything else for that matter) you can explicitly set the attribute:

u[:secret] = nil
u.secret.nil?
=> true

This could be a lot more consistent and there should be a option to disable the behavior, I'll add it to my to-do.

That makes sense! Thanks for the reply and the workaround/solution.

When I try to set encrypted field to blank (remove text of field from view), the data is retained and its not updated with blank. The form is not showing any errors.

That is because the resulting empty string is encrypted. Check in the controller is the string is empty and set the field to nil

Like that?

if (params[:contact][:mobile].empty?)
  params[:contact][:mobile] = nil
end

Yep

hum, it does not work for me. The value is retained and not set to nil. any clues?

If you want to clear it you'll probably need to do something like:

@model[:attribute] = nil

and then save it.

works like a charm. Thanks!
