in my model, i have a table called "person" with unique constraint on "name"
and "surname" columns.
then, i want to prevent duplicates creations by retrieving a message to the
user if once tries to create an existing person.
at the moment, i use my own validator (inspired by "propelUniqueValidator")
which performs a "select" on the database and retrieve an error if the data
already exists.
if possible, i would like to avoid this preliminar request by catching and
handling the "duplicate entry" propel exception ("Unable to execute INSERT
statement . . . Duplicate entry . . .") thrown by propel when i perform the
"insert" request.
my very problem is that this exception has no particular code (0) then i
don't know how to catch it !
how do you handle this kind of "duplicate creation" scenario ? any idea ?
