Pouvez-vous publier la pile complète. Juste fait une petite application avec id convivial et les portées par défaut et je n'ai pas de problèmes –

@japed, bien sûr pour jeter un coup d'oeil! – daveomcd

Ce sera avant cela, où vous obtenez @player mais je ne pense pas que des rails évalues jusqu'à ce qu'il doit. Pour y accéder, vous pouvez simplement appeler non délimité.

@player = Player.unscoped.find(params[:id)

bien que j'ai déjà essayé ce '@player = Player.unscoped.friendly.find (params [: id])' désolé oublié de mentionner que je vais l'ajouter ci-dessus. – daveomcd

Donc, en utilisant 'byebug' cette ligne que vous avez suggérée fonctionne très bien, mais quand j'appelle la méthode de mise à jour, c'est quand elle semble rendre l'erreur que j'ai mentionnée. Aussi sélectionné manuellement à partir de la base de données et l'enregistrement est là. – daveomcd

Donc, j'ai découvert que je reçois l'erreur lors de l'utilisation de Carrierwave, Si je ne télécharge pas une photo de profil, cela fonctionne très bien. Donc j'essaie de découvrir le correctif pour ça. Merci – daveomcd

Player.unscoped.find(id)

Renvoie un champ pour le modèle sans les champs précédemment définis.

class Post < ActiveRecord::Base 
    def self.default_scope 
    where published: true 
    end 
end 

Post.all         # Fires "SELECT * FROM posts WHERE published = true" 
Post.unscoped.all       # Fires "SELECT * FROM posts" 
Post.where(published: false).unscoped.all # Fires "SELECT * FROM posts"

Dans la classe du joueur, on peut définir un nouveau champ d'application: with_errors, il sera unscope la valeur par défaut:

class Player < ActiveRecord::Base 
    default_scope { where(imported_with_errors: false) } 
    scope :with_errors, -> { unscope(where: :imported_with_errors) } 
end

Ainsi, vous pouvez simplement l'utiliser pour trouver un joueur comme votre besoin:

Player.with_errors.find(params[:id])
