Hi!
I have a model "Adherent" correspondint to a table "adherents" in my
Postgres database. In this table, when I create a row from my app, I want
to set the "creator_id" column to same value as id. With Sequel the
folowing intruction works ok
DB[:adherents].insert(:name => "foo", :creator_id =>
Sequel.function("currval","adherents_id_seq"))
But this one does fail:
Adherent.new(:name => "foo", :creator_id =>
Sequel.function("currval","adherents_id_seq"))
This fail at validation, because the sequel function object is not an
integer as expected.
To bypass validation, I affect the value in the "before_create" hook:
def before_create
super
self.creator_id ||= Sequel.lit("currval('adherents_id_seq')")
end
This is also failing
using Sequel.lit("currval('adherents_id_seq')") the error is:
ERROR -- : PG::InvalidTextRepresentation: ERREUR: syntaxe en entrée
invalide pour le type integer : « currval('adherents_id_seq') »
using Sequel.function("currval","adherents_id_seq") the error is:
ERREUR: syntaxe en entrée invalide pour le type integer : «
#<Sequel::SQL::Function:0x000055f8811d3fd8> »
(PG::InvalidTextRepresentation)
I feel this is because of the auto-generated PREPARE statement
PREPARE smpsp_1 AS INSERT INTO "adherents" ("name", "creator_id") VALUES
($1, $2) RETURNING "id", "prenom", "nom", "annee_naissance", "email",
"tel_portable", "motivations", "commentaires", "echeance_SEPA",
"envoi_papier", "adresse_id", "premiere_adhesion", "stop_relance",
"perdu_trace", "updated_at", "created_at", "titre", "date_naissance",
"sceau", "creator_id", "updater_id"
the $2 variable should not be declared, instead it should be written the
raw sql
currval('adherents_id_seq')
When using a Sequel::Model instance, is there a way to put a sql function
as a value for a given field ?
Thanks for your help.
