foreign keys - Rails Many_to_many association -

i new rails , have problem. have 3 tables: books, authors, books_authors. in view display 2 columns. first should display author's name , second books author has written decimal. in books_authors table foreign keys belongs primary keys in books , authors tables. schema:

activerecord::schema.define(version: 20150709110928)  create_table "authors", force: :cascade |t|   t.string   "name"   t.string   "surname"   t.datetime "created_at", null: false   t.datetime "updated_at", null: false end  create_table "authors_books", id: false, force: :cascade |t|   t.integer  "author_id"   t.integer  "book_id"   t.datetime "created_at", null: false   t.datetime "updated_at", null: false end  add_index "authors_books", ["author_id"], name:   "index_author_books_on_author_id" add_index "authors_books", ["book_id"], name:    "index_author_books_on_book_id"  create_table "books", force: :cascade |t|   t.string   "title"   t.datetime "created_at", null: false   t.datetime "updated_at", null: false end 

and models looks like:

class author < activerecord::base   has_many :authors_books   has_many :books, through: :authors_books end  class book < activerecord::base   has_many :authors_books   has_many :authors, through: :authors_books end 

how it?

in model authors_book, should this

class authorsbook < activerecord::base    belongs_to :author    belongs_to :book end 

each entry in authors_books table has author_id , books_id holds many many assosiation. when

  @author.books 

it fetch books author has written.

you can traverse books , display them.
