ok, new question: i'm following yariv's login tutorial. what i'm
getting is, you store the cookie in the db (in my case mysql), then
base64:encode it and put it in the arg's cookie field...and then,
after redirecting to another component, you get the cookie and
base64:decode it and query the db for it.
the problem is that the decoded key doesn't match the key in the
database, so my query comes up empty. i've tried storing it as
char(20), varchar(20), binary, and blob... the way i test it is just
fetching the cookie from the arg and decoding it, and then fetching
the stored cookie of my user, and then sending them both to the view.
each one gets printed like this:
<% show_data(Data) %>
<% Data %>
when i print them out they're visibly different.
so what should i do with the cookie, or with the database, to get this
to work? this seems like a problem of converting between types but i
don't know how erlang handles that. thanks for your help!
