Rails 3.2 Postgres Salva errore "ActiveRecord :: Istruzione non valida: PG :: Errore: ERRORE: Errore di sintassi vicino a" T "nella posizione 5"

Question

La mia app ha iniziato a generare errori quando provo a salvare una determinata classe nel database. Non sono sicuro di cosa abbia causato questo evento - ho avuto tutti i tipi di problemi con i database negli ultimi giorni ....

In ogni caso, il mio modello sembra funzionare bene (è calcola correttamente tutti i valori di before_save), ma poi prova a salvare nel database e fa esplodere.

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"]] 

Lanci questo errore:

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

Non ho idea di cosa questo significhi di errore (o che cosa è questo 'T' .....), o anche dove per iniziare la risoluzione dei problemi esso .. .. Qualsiasi aiuto sarebbe apprezzato.

posso pubblicare qualsiasi informazione potrebbe essere necessario per capirlo ....

migrazione Rilevante:

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);"

UPDATE 1 Qualche codice modello come richiesto.

roba macro:

attr_accessible :weights 

serialize :correlation_matrix 
serialize :weights 

has_and_belongs_to_many :securities, :uniq => true 
has_and_belongs_to_many :efficient_frontiers 

before_validation :format_weights_tickers, :add_securities, :validate_weights, :set_weights_in_hstore, :build_correlation_matrix, :set_mean_return, :set_standard_deviation 

validates_presence_of :mean_return, :std_dev, :securities, :correlation_matrix, :weights 
validates_numericality_of :mean_return, :std_dev 

validate :uniqueness_of_weights 

before_destroy :check_for_dependent 

scope :by_std_dev, :order => 'std_dev ASC' 

nulla e tutto ciò che posso trovare a che fare con la colonna hstore tutto quello che ho davvero usare hstore per è per una ricerca su ticker specifici. Questo funzionava ... non so cosa sia cambiato. Potrei aver aggiornato Postgres (stavo armeggiando con homebrew) o potenzialmente qualcosa cambiato con i binari. Ho provato a tornare alla 3.2.3 ma ho avuto lo stesso errore.

def self.find_by_hstore(search_key, search_value) 
    where("data @> (:key => :value)", :key => search_key.to_s, :value => search_value.to_s) 
end 

def set_weights_in_hstore 
    self.data = {} if self.data.nil? 
    weights.each_pair {|ticker, weight| self.data[ticker.to_s] = weight} 
end 

posso postare la totalità del modello se questo è troppo sconnesso. Fammi sapere!

UPDATE # 2 - sto ottenendo errori simili anche altrove ....

Dopo una semplice registrazione utente ....

UDPATE 3

Ci sembra essere qualcosa di funky in corso con il mio database/tabella utente. Ho il seguente errore durante il caricamento l'ambiente in una migrazione:

rake aborted! 
PG::Error: ERROR: relation "users" does not exist 
LINE 4:    WHERE a.attrelid = '"users"'::regclass 
             ^
:    SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc,   a.attnotnull 
       FROM pg_attribute a LEFT JOIN pg_attrdef d 
       ON a.attrelid = d.adrelid AND a.attnum = d.adnum 
      WHERE a.attrelid = '"users"'::regclass 
       AND a.attnum > 0 AND NOT a.attisdropped 
      ORDER BY a.attnum 

Answer 1

Ho appena avuto un problema simile, on Rails 3.2. Se non si utilizza Rails tronco (lavorando per 4,0), non capisce il hstore nativamente - è necessario definire un codificatore serializzazione (che è fornito dal activerecord-postgres-hstore gemma), in questo modo:

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