Raylar 3.2 Postgres Kaydetme Hatası "ActiveRecord :: StatementInvalid: PG :: Hata: HATA: 5 konumunda" T "yakınında sözdizimi hatası"

Question

Uygulamam, belirli bir sınıfı veritabanına kaydetmeye çalıştığımda hata atmaya başladı. Bunun tam olarak başlamasının tam olarak ne olduğundan emin değilim - Son birkaç gündür her türlü veritabanı sorununu yaşıyorum ....

Her halükarda, benim modelim gayet iyi çalışıyor gibi görünüyor. tüm before_save değerlerini düzgün şekilde hesaplar), ancak sonra veritabanına kaydetmeye çalışır ve patlar. Bu hata araçlarının (veya bu 'T' ne .....), hatta bunu giderme başlamak için hiçbir fikrim yok

ActiveRecord::StatementInvalid: PG::Error: ERROR: Syntax error near 'T' at position 5 

..:

SQL (0.8ms) INSERT INTO "portfolios" ("correlation_matrix", "created_at", "data", "mean_return", "std_dev", "updated_at", "weights") VALUES ($1, $2, $3, $4, $5, $6, $7) RETURNING "id" [["correlation_matrix", "--- \n- - 1.0\n - -0.4873114574375062\n- - -0.4873114574375062\n - 1.0\n"], ["created_at", Sat, 16 Jun 2012 15:12:35 MDT -06:00], ["data", {"TSX"=>0.5, "VUSTX"=>0.5}], ["mean_return", #<BigDecimal:7fadb119b750,'0.488052381E-1',18(45)>], ["std_dev", #<BigDecimal:7fadb119b598,'0.7668705159 123244E-1',18(45)>], ["updated_at", Sat, 16 Jun 2012 15:12:35 MDT -06:00], ["weights", "--- \nTSX: 0.5\nVUSTX: 0.5\n"]] 

bu hatayı Atar .. Herhangi bir yardım takdir edilecektir.

Bunu anlamaya için gerekli ne olursa olsun bilgi gönderebilir

....

İlgili göç:

create_table :portfolios do |t| 
    t.text :weights 
    t.decimal :mean_return, :precision => 15, :scale => 10 
    t.decimal :std_dev, :precision => 15, :scale => 10 
    t.text :correlation_matrix 
    t.hstore :data 

    t.timestamps 
    end 

    execute "CREATE INDEX portfolios_gin_data_hstore ON portfolios USING GIN(data);" 

Tam yığın takibi:

Benim veritabanı/kullanıcı tablosu ile devam eden bir şey gibi görünüyor. Çevre geçişi yükleme sırasında aşağıdaki hatayı alıyorum:

Answer 1

Rails 3.2'de benzer bir sorunla karşılaştım. Eğer Raylar bagajı (4.0 doğru çalışma) kullanmıyorsanız, bu doğal hstore anlamıyor - Eğer (activerecord-postgres-hstore taş tarafından sağlanan) bir seri kodlayıcı tanımlamak şöyle gerekir:

class Example < ActiveRecord::Base 
    serialize :data, ActiveRecord::Coders::Hstore 
end
