Groupify NameError: неинициализированная константа Пользователь :: GroupMembership

Question

Я выполнил документацию, вручную создав файл миграции и модели. У меня уже была модель пользователя в мое приложение:

user.rb:

class User < ActiveRecord::Base 
    authenticates_with_sorcery! 

    validates :name, presence: true 
    validates :password, length: { minimum: 4 } 
    validates :password, confirmation: true 
    validates :password_confirmation, presence: true 

    validates :email, uniqueness: true 

    has_many :testimonials 
    has_many :materials 

    groupify :group_member 
    groupify :named_group_member 
end 

class Assignment < ActiveRecord::Base 
    groupify :group_member 
end 

group.rb:

class Group < ActiveRecord::Base 
    groupify :group, members: [:users, :assignments], default_members: :users 
end 

GroupMembership.rb:

class GroupMembership < ActiveRecord::Base 
    groupify :group_membership 
end 

schema.rb :

ActiveRecord::Schema.define(version: 20150301133633) do 

    create_table "group_memberships", force: :cascade do |t| 
    t.string "member_type" 
    t.integer "member_id" 
    t.integer "group_id" 
    t.string "group_name" 
    t.string "membership_type" 
    end 

    add_index "group_memberships", ["group_id"], name: "index_group_memberships_on_group_id" 
    add_index "group_memberships", ["group_name"], name: "index_group_memberships_on_group_name" 
    add_index "group_memberships", ["member_id", "member_type"], name: "index_group_memberships_on_member_id_and_member_type" 

    create_table "groups", force: :cascade do |t| 
    t.string "type" 
    end 

    create_table "materials", force: :cascade do |t| 
    t.string "level" 
    t.text  "description" 
    t.string "link" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    t.string "title" 
    t.integer "user_id" 
    end 

    add_index "materials", ["user_id"], name: "index_materials_on_user_id" 

    create_table "testimonials", force: :cascade do |t| 
    t.text  "content" 
    t.integer "user_id" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

    add_index "testimonials", ["user_id", "created_at"], name: "index_testimonials_on_user_id_and_created_at" 
    add_index "testimonials", ["user_id"], name: "index_testimonials_on_user_id" 

    create_table "tests", force: :cascade do |t| 
    t.string "name" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

    create_table "users", force: :cascade do |t| 
    t.string "email",   null: false 
    t.string "crypted_password" 
    t.string "salt" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    t.string "name" 
    end 

    add_index "users", ["email"], name: "index_users_on_email", unique: true 

end 

Я бегу мой пульт в изолированном режиме и сделать:

group = Group.new 
user = User.new 

group.add user 

И моя консоль извергает:

NameError: uninitialized constant User::GroupMembership 

Что происходит?

РЕШИТЬ: Класс GroupMembership.rb написано в ГорбатыйРегистр, так что имя файла должно быть:

group_membership.rb
