在显示视图中包括Rails Index支架

Question

Sorry if this has been asked - i looked but couldnt find.

I'm trying to put the following code into a partial:

<% @products.each do |product| %>
   <%= product.id %>'>
   <img src='<%= product.image_1 %>'/>
   <%= product.title %>
   <%= product.image_2 %>
 <% end %>

But can't make it work - can anyone help?

Thanks.

Answer 1

When calling your partial you need to provide the @products variable

<%= render partial: 'your_partial', locals: {products: @products} %>

In your partial:

<% products.each do |product| %>
  <%= product.id %>
  <img src='<%= product.image_1 %>'/>
  <%= product.title %>
  <%= product.image_2 %>
<% end %>

A better way to do it would be just to pass the collection into the partial:

<%= render partial: 'your_partial', collection: @products %>

Then create the _product partial with the following code:

<%= product.id %>
<%= image_tag(product.image_1) %> 
<%= product.title %>
<%= product.image_2 %>
