Show each users each post.

Rails • Asked by Peter Boomsma

I'm trying to create a page where all my users are listed, and every movie they've added to their account.

My UserController index def

def index
  @users = User.all
  if logged_in?
    @user = User.find(session[:user_id])
    @movies = @user.movies

And my user index.html.haml

  - @users.each do |user|
      = link_to, user
      - @movies.each do |movie|
          = movie.title
          = image_tag(movie.image)

At the moment the [email protected] do shows all the movies that are added to my database, it does this for every user. And not specifically the movies that that user has in his account. How do I show each movie for each user?

So you'll need a join table between Movies and Users. Something like UserMovie is a standard naming scheme for that. You could also give them a name like Favorite.

In essence you'll do this:

class User < ActiveRecord::Base
  has_many :user_movies
  has_many :movies, through: :user_movies

class UserMovie < ActiveRecord::Base
  belongs_to :movie
  belongs_to :user

class Movie < ActiveRecord::Base
  has_many :user_movies
  has_many :users, through: :user_movies

This lets you access @user.movies to get their movies and you can also get a list of a movie's users (people who favorited it for example) by doing @movie.users

You will need some mechanism to create the join table records, but if you check out the screencast I did on hearts/favoriting/liking, that's pretty much exactly what you'll be doing for that.
