Combining Multiple Models into one view Rails

Question

I want to show data from 4 models into a single view. I have created a separate controller for this named posts_controller.rb and in views I have created posts folder and created index.html.erb file.

After that in controllers file I have added the following code.

 class PostsController < ApplicationController

    def index
        @quotes = Quote.all.order("created_at DESC")
        @images = Image.all.order("created_at DESC")
        @jokes = Joke.all.order("created_at DESC")

        @items = (@quotes.to_a + @jokes.to_a)
    end
end

And here is the view file where I am trying to show 2 items data as for now. But its not working. Pls check the code.

<% if @items.any? %>

  <div class="col-md-12">
    <% @items.each.do |item| %>
      <% if item.is_a? Quote %>

      <div class="postbg">

              <%= quote.quotefie %>
              <div class="wedate pull-right wehi">
              <%= quote.created_at.strftime("%b %d, %Y") %>
            </div>
            <div class="clearfix"></div>
              <em class="pull-right wehi" style="margin-top:20px;"> - <%= quote.author %></em>
              <%= link_to 'Show', quote %>
              <%= link_to 'Edit', edit_quote_path(quote) %>
              <%= link_to 'Destroy', quote, method: :delete, data: { confirm: 'Are you sure?' } %>
         </div>
    <% else %>

       <% @jokes.each do |joke| %>

       <div class="postbg">

              <%= joke.jokefie %>
              <div class="wedate pull-right wehi">
              <%= joke.created_at.strftime("%b %d, %Y") %>
            </div>
            <div class="clearfix"></div>
              <%= link_to 'Show', joke %>
              <%= link_to 'Edit', edit_joke_path(joke) %>
              <%= link_to 'Destroy', joke, method: :delete, data: { confirm: 'Are you sure?' } %>
         </div>

         <% end %>
         <% end %>
  </div>

<% end %>

Here is the error it is showing.

undefined method `do' for #<Enumerator:0x007fd55fb032b8>

Answer 1

Your problem is in this line here:

<% @items.each.do |item| %>

do defines a block, not a method call, so it should be:

<% @items.each do |item| %>

Note the removed . .

You've used do correctly further down the view when you use @jokes.each do |joke| .

Answer 2

This line

<% @items.each.do |item| %>

should be

<% @items.each do |item| %>
