Hstore Postgres Rails4的語法錯誤

Question

嗨，我遇到了Postgres語法錯誤，使用HSTORE時似乎無法追蹤到

錯誤：

2.0.0p247 :021 > e.save                                                                                                                                                                                                                        
   (218.8ms)  BEGIN

PG::InternalError: ERROR:  Syntax error near 'e' at position 13                                                                                                                                                                                
: INSERT INTO "communications" ("created_at", "incoming", "properties", "type", "updated_at") VALUES ($1, $2, $3, $4, $5) RETURNING "id"                                                                                                       
   (218.4ms)  ROLLBACK 

當我嘗試保存電子郵件記錄時，該錯誤來自Rails控制台，在我的應用程序中，電子郵件繼承自Communication模型，並且記錄存儲在數據庫的“ communications”表中。

楷模：

class Communication < ActiveRecord::Base
    belongs_to :patient
    belongs_to :practice
end

和...

class Email < Communication
    store_accessor :properties, :to, :cc, :bcc, :message, :subject
end

不知道為什么，但是幾天后數據庫或服務器重新啟動可能已解決了問題……非常感謝您的協助@ user647622
