Rails 3.2 Error de Error de Postgres "ActiveRecord :: StatementInvalid: PG :: Error: ERROR: Error de sintaxis cerca de 'T' en la posición 5"

Question

Mi aplicación ha comenzado a arrojar errores cuando intento guardar una clase en particular en la base de datos. No estoy seguro de qué fue lo que provocó que esto comenzara a suceder. He tenido todo tipo de problemas con la base de datos durante los últimos días ...

En cualquier caso, mi modelo parece estar funcionando bien (es calculando correctamente todos los valores before_save), pero luego intenta guardar en la base de datos y explota.

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"]] 

Lanza este error:

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

no tengo idea de lo que significa este error (o lo que es esta 'T' .....), o incluso por dónde empezar a solucionar problemas que .. .. Cualquier ayuda sería apreciada.

me pueden enviar cualquier información que pueda ser necesaria para resolver esto ....

create_table :portfolios do |t|

    t.decimal :mean_return, :precision => 15, :scale => 10 
    t.decimal :std_dev, :precision => 15, :scale => 10

ACTUALIZA 1 Algunos modelos de código según lo solicitado.

cosas macro:

validates_numericality_of :mean_return, :std_dev 

validate :uniqueness_of_weights 

before_destroy :check_for_dependent 

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

cualquier cosa y todo lo que puedo encontrar que ver con la columna de la hstore todo lo que realmente utilizo para hstore es para una búsqueda de teletipos específicos. Esto solía funcionar ... No sé qué cambió. Pude haber actualizado Postgres (estaba jugando con homebrew) o potencialmente algo cambió con los rieles. Intenté volver a 3.2.3 pero obtuve el mismo error.

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 

puedo publicar la totalidad del modelo si esto es demasiado inconexo. ¡Házmelo saber!

Answer 1

Acabo de tener un problema similar, en Rails 3.2. Si usted no está utilizando rieles tronco (trabajando hacia 4.0), que no entiende el hstore forma nativa - es necesario definir un codificador de serialización (que es proporcionada por el activerecord-postgres-hstore joya), así:

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