Heroku "Es tut uns leid, aber etwas ging schief."

Question

Ich entwickle eine Rails-App, die in der Entwicklung gut funktioniert. Wenn ich jedoch auf Heroku umstelle, stoße ich auf Probleme. Die App funktioniert gut, bis ich einen neuen Benutzer erstellen kann. In diesem Fall bekomme ich "Es tut uns leid, aber etwas ist schiefgelaufen." Ich habe versucht, die Datenbank über pg:reset zu entladen und die Datenbank zu migrieren. Hier ist meine Protokolle heroku logs:

Wer irgendwelche Ideen, was dieses verursachen würde? Sehr verwirrend, dass es in meiner Entwicklungsumgebung funktioniert, aber nicht in Produktion auf Heroku.

WowCharacter Modell:

# == Schema Information 
# 
# Table name: wow_characters 
# 
# id     :integer   not null, primary key 
# user_id   :integer 
# realm    :string(255) 
# name    :string(255) 
# level    :integer 
# race    :string(255) 
# class_id   :string(255) 
# gender    :integer 
# guild    :text 
# talents   :text 
# items    :text 
# professions  :text 
# progression  :text 
# achievement_points :integer 
# thumbnail   :string(255) 
# last_modified  :datetime 
# created_at   :datetime  not null 
# updated_at   :datetime  not null 
# stats    :text 
# appearance   :text 
# 

class WowCharacter < ActiveRecord::Base 

    # Set accessible fields 
    attr_accessible :user_id, :realm, :name, :level, :race, :class_id, :gender, :guild, :stats, 
        :talents, :items, :professions, :appearance, :achievement_points, :thumbnail, 
        :last_modified, :wow_character 

    serialize :guild 
    serialize :talents 
    serialize :items 
    serialize :professions 
    serialize :progression 
    serialize :stats 
    serialize :appearance 

    # Create reference to User model 
    belongs_to :user 
end 

Nicht sicher, ob das hilft, aber nach etwas mehr Tests machen kann ich bestätigen, dass es aufhört auf: app[web.1]: cache: [POST /users] invalidate, pass jedes Mal. Ich habe das herausgefunden, indem ich die Heroku-Logs verfolgt habe.

Answer 1

Ich konnte dieses Problem beheben. Ich entschied mich, SQLite3 durch Postgre in meiner Entwicklung ENV zu ersetzen, so dass es meinem Setup in Heroku entsprach. Nachdem ich das getan hatte, war ich in der Lage, das Problem viel einfacher zu debuggen und was es letztendlich war, war ein Typcasting-Problem. Das :last_modified Feld ist :datetime aber der Wert ich in sie schob war ein UNIX-Zeitstempel und wurde ein Fehler mit Postgre werfen:

„Typ-Zeitstempel ohne Zeitzone aber Ausdruck vom Typ bigint“

ich war in der Lage, das Problem zu beheben, indem eine Konvertierung auf dem UNIX Zeitpunkt ausgeführt wird:

:last_modified = Time.at(timestamp)
