can you support boss_db:find have a hook

[roowe]

I want to save simple erlang term(like [1,2,3], [{lv, 1}, {vip, 1}]) in mysql, so it is varchar in mysql. when I select it, then some fields alway string_to_term.it just like before_update hook.

bitstring_to_term(BitString) -> string_to_term(binary_to_list(BitString)). string_to_term(String) -> case erl_scan:string(String++".") of {ok, Tokens, _} -> case erl_parse:parse_term(Tokens) of {ok, Term} -> Term; _Err -> undefined end; _Error -> undefined end.
