rake db: schéma: la charge n'a pas pu trouver une table

StackOverflow https://stackoverflow.com/questions/8353744

Question

EDIT normalocity : Ma réponse n'a pas été en mesure de résoudre ce problème, donc je poste une prime pour des solutions alternatives.

Question d'origine:

J'ai commencé à travailler sur un projet il y a Rails une semaine, en changeant plusieurs fois le schéma de base de données à l'aide des migrations. Hier, je tente de créer ma base de données (environnement Developement, configuration par défaut) à partir de zéro en utilisant ces commandes: 

rake db:drop
rake db:create
rake db:schema:load

Je suis arrivé ce message lors du chargement du schéma en utilisant l'option --trace: 

** Invoke db:schema:load (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!

Tasks: TOP => db:schema:load => environment

Rails débutant, je n'ai aucune idée comment résoudre ce problème en particulier mon schema.rb ont des commandes pour créer des galeries e tableau.

Mon code est disponible ici: https://github.com/fabienengels/portfolio

Était-ce utile?

La solution

Vous devez modifier votre /app/admin/photos.rb 

# /app/admin/photos.rb
index :as => :grid, :columns => 6 do |photo|
    Gallery.all.each do |gallery|
      scope gallery.slug.to_sym do |photos|
        photos.where(:gallery_id => gallery)
      end
    end
    # link_to(image_tag(photo.file.url(:thumb)), admin_photo_path(photo))
end

vous avez besoin de mettre ce code à l'intérieur du bloc index. Je commentais votre balise de lien là. Je vais laisser à vous de comprendre comment concevoir votre grille / bloc / whatever. assurez-vous qu'il est dans le champ d'index. Bonne chance.

Autres conseils

Donc, la question est que lorsque le chargement de votre application, il chargement de votre stuff activeadmin. Ce tour se termine à la course à pied Gallery.all savoir ce oscilloscopes à la configuration.

L'exécution d'une tâche Rake comme schema:load encore charge l'application, il est donc toujours essayer de faire Gallery.all mais vous avez juste laissé tomber / recréée le db il est dit à juste titre que la table n'est pas là.

Qu'est-ce que vous voulez être en mesure de faire est de dire ActiveAdmin pas pris la peine de se configurer, comme vous êtes juste en cours d'exécution des migrations.

Heureusement, il y a une $rails_rake_task variable globale qui est définie dans ces cas. J'essaie de ne pas courir le code dans votre active_admin chaque fois $rails_rake_task est initialiseur vrai ou si cela ne fonctionne pas aussi faire aucune configuration de activeadmin (par exemple la substance dans app / admin / photos) si $rails_rake_task est vrai.

Je ne l'ai jamais utilisé ActiveAdmin avant, mais à partir de la documentation, mais il semble que vous ne pouvez faire référence à un modèle unique dans un bloc de ActiveAdmin.register, ou que vous avez tout simplement pas fait le modèle Gallery intérieur visible de ce fichier.

Ainsi, app/admin/photos.rb où vous avez 

ActiveAdmin.register Photo do
  ...

  Gallery.all.each do |gallery|              # <= this is invalid, because this file 
    scope gallery.slug.to_sym do |photos|    # doesn't know what `Gallery` (and therefore
      photos.where(:gallery_id => gallery)   # `galleries` table`) is referring to
    end
  end

  ....
end

Je ne sais pas comment faire des enregistrements de ActiveAdmin imbriquées, ou même si vous le pouvez, mais le message d'erreur que vous obtenez est vous dire que Gallery n'est pas accessible dans le cadre de ce dossier, et par conséquent, il est comme, "Qu'est-ce que « table de galeries? Nous avons pas 'table' des galeries ici.".

Alors, vous pouvez essayer une de ces deux choses à résoudre et voir ce qui se passe - c'est, espérons-soit la réponse, ou vous mènera à la réponse:

  • Au sommet du fichier app/admin/photos.rb, ajoutez cette ligne exacte:
    • require '../models/gallery'
  • Si cela ne fonctionne pas, au lieu de Gallery.all.each... essayer
    • ActiveAdmin.register Gallery do suivi par ce même bloc
