Question

J'ai un problème avec ActiveAdmin en utilisant Ruby Ruby 1.9.2p290 et Ruby sur Rails 3.2.1.

J'ai utilisé cette page wiki pour configurer la ressource pour les administrateurs qui fonctionne parfaitement: Votre première ressource d'administration: l'administrateur

Après cela, je voulais créer la ressource pour mon modèle de projet. Les migrations pour cela ressemble à ceci:

class CreateProjects < ActiveRecord::Migration
  def change
    create_table :projects do |t|
      t.string :name
      t.text :description
      t.boolean :isactive

      t.timestamps
    end
  end
end

class AddSlugToProjects < ActiveRecord::Migration
  def change
    add_column :projects, :slug, :string
    add_index :projects, :slug
  end
end

Mon modèle de projet:

class Project < ActiveRecord::Base

  scope :isactive, :conditions => ["isactive = ?",true]

  extend FriendlyId
  friendly_id :name, use: [:slugged, :history]

  attr_accessible :name, :description, :isactive

end

Et c'est le project_controller:

class ProjectsController < ApplicationController

  def index
    #
    # @projects gets filled in application_controller to be always
    # available for the twitter bootstrap navbar
    # @projects = Project.isactive.find(:all, :order => 'LOWER(name) asc')
    #
  end

  def show
    @project = Project.isactive.find(params[:id])
    if request.path != project_path(@project)
      redirect_to @project, :status => :moved_permanently
    end
  end

end

L'administrateur / projects.rb est actuellement «vide»

ActiveAdmin.register Project do  
end

Et après tout cela, tout ce que j'obtiens est l'erreur suivante:

Et je n'ai aucune idée du problème ...

Était-ce utile?

La solution

Ah, j'ai trouvé la solution. Je ne sais pas exactement pourquoi l'erreur s'est produite, mais j'ai dû changer mon application_controller.

Dans l'application_Controller, j'ai récupéré tous les projets sur @projects:

before_filter :getActiveProjects

protected

  def getActiveProjects
    @projects = Project.isactive.find(:all, :order => 'LOWER(name) asc')
  end

Cela confondait Activeadmin. Après avoir changé cela pour

before_filter :getActiveProjects

protected

  def getActiveProjects
    @projects_all = Project.isactive.find(:all, :order => 'LOWER(name) asc')
  end

et projets_Controller Index Action à

def index
  @projects = @projects_all
end

Tout a bien fonctionné;)

Autres conseils

Une solution plus facile consiste à sauter simplement le filtre dans le contrôleur d'administration actif particulier:

ActiveAdmin.register Project do  
    controller do
      skip_before_filter :getActiveProjects
    end
end

L'administrateur actif fait un traitement spécial de @resource variables. Où resource Le nom de classe correspondant à la méthode d'enregistrement. Donc pour le code:

ActiveAdmin.register Project do  
end

Le nom de la variable est

`@project`

Nous ne devons pas attribuer de la valeur à la variable avec un tel nom. De telles variables peuvent également être l'objet de la classe ActiveRecord :: Relation. Et comment @oliver écrivent le nom comme @projects_all est un bon choix. L'utilisation de skip_before_filter résout également le problème.

Une chose astucieuse doit vérifier. Le contrôleur des ressources peut ne pas avoir de filtres. Le contrôleur des ressources peut ne pas existent du tout. Quel est le nom du filtre à mettre sur skip_before_filter? Et où sont ces filtres? Le contrôleur d'application par défaut est utilisé de toute façon. Le filtre peut être installé sur le contrôleur d'application principal. Le message d'erreur de ce problème n'est pas du tout informatif. Il faut donc également vérifier le contrôleur d'application pour les filtres installés.
