ruby on rails - Coping with "string contains null byte" sent from users -

-

i have api controller receives information media file's path , id3 tags, , saves them active record instance, using postgresql/rails.

sometimes user sends strings such as:

"genre"=>"hip-hop\u0000hip-hop/rap"

and rails/postgres aren't happy when trying persist on save:

an argumenterror occurred in internals#receive:   string contains null byte  activerecord (3.2.21) lib/active_record/connection_adapters/postgresql_adapter.rb:1172:in `send_query_prepared'

how can clean string in ruby remove null bytes?

the gsub method on string suitable. can string.gsub("\u0000", '') rid of them.
