index.html.erb

<h1>Product Listings</h1>
        <%= @products.each do |p| %>
            <li><%= p.name %></li>
            <li><%= p.description %></li>
            <li><%= sprintf("$%0.02f", p.price) %></li>
            <li><%= p.photo %></li>
        <% end %>

Any idea on how to make Rails only display the iterations through the model and not the hash at the bottom?

Answer 1

这是你的问题：

<%= @products.each do |p| %>

那应该是：

<% @products.each do |p| %>

因为等号<%=导致它输出返回值，而不仅仅是作为流控制。
