Layouts

In the last video, we ended up with a controller that rendered inline views that looks like this:

class PostsController < ApplicationController
  before_action do
    @blog = current_user.blog
    @posts = @blog.posts
  end

  class Index < Phlex::HTML
    def initialize(posts:)
      @posts = posts
    end

    def template
      h1 "Posts"
      ul do
        @posts.each do |post|
          li do
            a href: post_path(post), post.title
          end
        end
      end
    end
  end

  def index
    render Index.new(posts: @posts)
  end

  # ...
end
