Rails 3.2 Postgres-Speicherfehler “ActiveRecord :: StatementInvalid: PG :: Error: ERROR: Syntaxfehler in der Nähe von 'T' an Position 5”

Meine App hat angefangen, Fehler auszulösen, wenn ich versuche, eine bestimmte Klasse in der Datenbank zu speichern. Ich bin mir nicht sicher, was genau dazu geführt hat - ich hatte in den letzten Tagen alle möglichen Datenbankprobleme ...

In jedem Fall scheint mein Modell einwandfrei zu funktionieren (es berechnet alle before_save-Werte ordnungsgemäß), aber dann wird versucht, sie in der Datenbank zu speichern, und es wird in die Luft gesprengt.

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"]]

Löst diesen Fehler aus:

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

Ich habe keine Ahnung, was dieser Fehler bedeutet (oder was dieses "T" ist ...) oder wo ich mit der Fehlerbehebung beginnen soll ... Jede Hilfe wäre willkommen.

Ich kann jede Information posten, die nötig ist, um das herauszufinden ...

Relevante Migration:

  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 Modellcode wie angefordert.

Makrosachen:

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'

Alles und jedes, was ich mit der HStore-Spalte finden kannAlles, wofür ich HStore wirklich benutze, ist die Suche nach bestimmten Tickern. Das hat früher funktioniert ... Ich weiß nicht, was sich geändert hat. Möglicherweise habe ich Postgres aufgerüstet (ich habe mit Homebrew rumgespielt) oder möglicherweise etwas mit Rails geändert. Ich habe versucht, zu 3.2.3 zurückzukehren, aber ich habe den gleichen Fehler erhalten.

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

Ich kann das gesamte Modell posten, wenn dies zu unzusammenhängend ist. Gib mir Bescheid!

UPDATE Nr. 2 - Ich erhalte ähnliche Fehler auch an anderer Stelle.

Nach einer einfachen Benutzeranmeldung ....

In meiner Datenbank / Benutzertabelle scheint etwas Ungewöhnliches vor sich zu gehen. Beim Laden der Umgebung in einer Migration wird die folgende Fehlermeldung angezeigt:
