Мое приложение начало выдавать ошибки, когда я пытаюсь сохранить определенный класс в базе данных. Я не уверен, что именно привело к тому, что это начало происходить - у меня были все виды проблем с базами данных в течение последних нескольких дней ...

В любом случае, моя модель работает нормально (она правильно рассчитывает все значения before_save), но затем пытается сохранить ее в базе данных и взрывается.

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"]]

Выдает эту ошибку:

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

Я понятия не имею, что означает эта ошибка (или что это за «T»…), или даже с чего начать ее устранение .... Любая помощь будет принята с благодарностью.

Я могу опубликовать любую информацию, которая может понадобиться, чтобы понять это ....

Соответствующая миграция:

  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);"

Трассировка полного стека:

UPDATE 1 Код модели по запросу.

макросъемка:

attr_accessible :weights

validate :uniqueness_of_weights 

before_destroy :check_for_dependent

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

все, что я могу найти, чтобы сделать с колонкой HStore all I really use HStore for is for a search on specific tickers. This used to work... I don't know what changed. I might have upgraded Postgres (I was fiddling around with homebrew) or potentially something changed with rails. I did try going back to 3.2.3 but I got the same 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

Я могу опубликовать всю модель, если она слишком разрозненная. Дай мне знать!

UPDATE #2 - I am getting similar errors elsewhere also....
