我使用Ruby ruby​​ 1.9.2p290和Ruby on Rails 3.2.1时遇到ActiveAdmin的问题.

我使用此Wiki页面为完美运行的AdminUsers设置资源:您的第一个管理资源:AdminUser

之后我想为我的项目模型创建资源.迁移的内容如下所示:

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

我的项目模型:

class Project < ActiveRecord::Base

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

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

  attr_accessible :name, :description, :isactive

end

这就是project_controller:

class ProjectsController < ApplicationController

  def index
    #
    # @projects gets filled …
