Mysql zu PostgreSql Rails 3 heroku app true/false

Alles funktioniert gut, bis ich zu Heroku schiebe, habe ich festgestellt, dass es mit diffident Möglichkeiten zu tun hat, mysql und postgres die booleschen Werte anzeigen?Mysql zu PostgreSql Rails 3 heroku app true/false

Ich verwende Rubin 1.9.2p318 und Rails 3.2.2 mit Mysql 5.2.35 auf Max OSX

Hier ist die Abfrage I

@special_offers = Wine.find(:all, :include => [:inventories], :conditions => ["inventories.special = ? AND inventories.warehouse_id IN (?)", "true", @wharehouses_array], :order => "inventories.updated_at DESC", :limit => 3)

zu laufen versuchen

Es scheint das Problem liegt mit der inventories.special = ?, "true" Dies funktioniert gut auf mysql, aber nicht, wenn ich zu Heroku schieben, die postgresverwendet

Ich habe versucht, die "wahre" mit 1 und "1" und "t" und t und wahr ersetzen, aber nichts scheint zu funktionieren?

Die SQL generiert und der Fehler von PostgreSQL wäre hilfreich. Sobald Sie diese haben, kann Ihnen jemand sofort sagen. Eigentlich, wenn Sie diese haben, werden Sie wahrscheinlich nicht fragen müssen. –

* nichts scheint zu funktionieren * ist keine gültige Fehlermeldung. –

Ich habe mir die Heroku-Protokolldatei angesehen, sie zeigt keine Fehlermeldungen an, sie fragt nur die Felder ab, wenn 'Wine.find (: all,: include => [: inventories],: conditions => [ "inventures.special =?", "true"]), weil der "wahre" Wert in postgresql nicht gleich ist? – Francois

Verwenden Sie die tatsächliche TrueClass, keine Zeichenfolge, und Rails wird es in die richtige Abfrage für Sie übersetzen.

Richtig:

"inventories.special = ?", true

Falsch:

"inventories.special = ?", "true"

Es ist kein Fehler zu werfen, weil der zweite noch eine gültige Abfrage erstellt, es ist nur für Aufzeichnungen, wo spezielle eine Zeichenkette mit dem eigentlichen ist wahre Charaktere drin.

ok lass mich das versuchen! :) Vielen Dank! – Francois

ok Ich habe '"inventures.special =?", "True" 'in' "inventories.special =?" Geändert, "true", aber jetzt zeigt es mir keine Ergebnisse? Lassen Sie mich einen Blick in Schema-Datei schnell – Francois

es sieht aus wie die Spalte ist in der Tat boolean, oder in mysql als Tinyint gezeigt, ist das korrekt? – Francois
