Cassandra Datastax Рубин Вставка ошибка

Question

У меня есть проблема с запросом вставить в рубине с Кассандрой,

Это мой стол:

CREATE TABLE testkeyspace.ticket (
    id int, 
    uid text, 
    annule boolean, 
    avoir decimal, 
    caisse int, 
    clotureid int, 
    couverts decimal, 
    creation_iso timestamp, 
    modif_iso timestamp, 
    montantencaisse decimal, 
    montantttc decimal, 
    nb_articles int, 
    numero int, 
    remise decimal, 
    remise_montant decimal, 
    remise_type text, 
    remise_valeur decimal, 
    rendu decimal, 
    stats_iso timestamp, 
    PRIMARY KEY (id, uid) 
) 

В рубина я сделал подготовить заявление:

insert_table_ticket = session.prepare("INSERT INTO ticket(id, uid, annule, avoir, caisse, clotureid, couverts,creation_iso, modif_iso, montantencaisse, montantttc, nb_articles, numero, remise,remise_montant, remise_type, remise_valeur, rendu,stats_iso) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)") 

И я поставлю эти значения для тестирования:

session.execute(insert_table_ticket, 
         1, 
         "test", 
         true, 
         1.1, 
         1, 
         1, 
         1.0, 
         1415350203, 
         1415350203, 
         1.1, 
         1.1, 
         1, 
         1, 
         1.1, 
         1.1, 
         "tests", 
         1.1, 
         1.1, 
         1415350203 
    ) 

Я получил эту ошибку:

Вы имели представление о моей проблеме? Спасибо

Answer 1

Проблема была с номером поплавка.

Ruby in float интерпретируется как double или float в cassandra. Чтобы положить десятичный символ в cassandra, мы должны поместить BigDecimal в Ruby.

источник: «http://datastax.github.io/ruby-driver/features/basics/»

решение:

session.execute(insert_table_ticket, 
        1, 
        "test", 
        true, 
        BigDecimal.new('1.1'), 
        1, 
        1, 
        BigDecimal.new('1.0'), 
        1415350203, 
        1415350203, 
        BigDecimal.new('1.1'), 
        BigDecimal.new('1.1'), 
        1, 
        1, 
        BigDecimal.new('1.1'), 
        BigDecimal.new('1.1'), 
        "tests", 
        BigDecimal.new('1.1'), 
        BigDecimal.new('1.1'), 
        1415350203 
)
