Show content from another controller in RoR

I have a problem: I want to show images inside the post views. I have the following controllers:

# posts_controller.rb
class PostsController < ApplicationController
  before_action :set_post, only: [:show]

  # GET /posts
  # GET /posts.json
  def index
    if params[:search]
      @posts = Post.search(params[:search]).order("created_at DESC")
    else
      @posts = Post.all.order('created_at DESC')
    end
  end

  # GET /posts/1
  # GET /posts/1.json
  def show
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_post
      @post = Post.find_by_slug(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def post_params
      params.require(:post).permit(:titulo, :slug, :texto, :imagem)
    end

end

and

# imgs_controller.rb
class ImgsController < ApplicationController
  before_action :set_img, only: [:show]

  # GET /imgs
  # GET /imgs.json
  def index
    @imgs = Img.all
  end

  # GET /imgs/1
  # GET /imgs/1.json
  def show
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_img
      @img = Img.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def img_params
      params.require(:img).permit(:imagem, :nome, :descricao, :to_slide)
    end
end

How can I call the methods 'index' and/or 'show' of ImgsController inside the views/posts/index.html.erb? Is there a way?

All the answers helped me to see the solution. I read the guide as Benjamin Sinclair said.

All I needed to do was put

@imgs = Img.all

inside the method 'index' of PostsController.

So, I called @imgs in views/posts/index.html.erb

Simple!

Thanks!

Nope.

If you want to render your images within your post views, you should make those resources available within your posts_controller.

I assume you have an association somewhat like

class Post
  has_many :images
end

So you could do something like:

# posts/index.html.erb
<% @posts.each do |post| %>
  <p><%= post.name %></p>
  <% @post.images.each do |img|
    <p><%= img.name %></p>
  <% end %>
<% end %>

Of course, you can render any template file:

render "posts/show" # or index

Docs

I assume that you have logic that works with both or you controller variables.
