Heroku にプッシュするまではすべて正常に動作します。mysql と postgres がブール値を表示する方法が異なることに関係しているとわかりました。

Max OSXでMysql 5.2.35とともにRuby 1.9.2p318とRails 3.2.2を使用しています

ここに私が実行しようとしているクエリがあります

@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)

問題はinventories.special = ?, "true" mysqlにあるようですが、postgresを使用しているherokuにプッシュするとうまくいきません

"true" を 1 と "1" と "t" と t と true に置き換えてみましたが、何もうまくいかないようですか?

文字列ではなく、実際の TrueClass を使用すると、Rails が正しいクエリに変換します。

正しい：

"inventories.special = ?", true

正しくない：

"inventories.special = ?", "true"

2 番目のクエリでも有効なクエリが生成されるため、エラーはスローされません。special が実際の真の文字を含む文字列であるレコードを探しているだけです。
