[RUBY] The problem that the contents of params are completely displayed in the [Rails] view

This is Qiita's first post.

Currently, I am creating an EC site with Ruby on Rails. When displaying the product list, the phenomenon that the contents (?) Of params are displayed in a row at the bottom of the view occurred as shown below.

It looks like this at the bottom of the view

#<Item id: 5, title: "Ah ah", artist: "Ah ah", text: "Ah ah", genre_id: 15, country: "JP", format_id: 2, status_id: 2, price: 500, stock: 1, created_at: "2020-09-30 15:55:20", updated_at: "2020-09-30 15:55:20">,# <Item id: 4, title: "Good", artist: "Good", text: "Good", genre_id: 13, country: "JP", format_id: 2, status_id: 2, price: 5000, stock: 1, created_at: "2020-09-30 15:32:51", updated_at: "2020-09-30 15:32:51">,

The following is omitted

<%= render "shared/header" %>
<div class="main-wrapper">
  <div class="item-wrapper">
    <%= @items.each do |item| %>
      <div class="item">
        <div class="item-image-content">
          <%= image_tag item.image, class:"item-image" %>
        <div class="item-format">
          <%= item.format.name %>
        <div class="item-artist">
          <%= item.artist %>
        <div class="item-title">
          <%= item.title %>
        <div class="item-price">
          <%= item.price %>Circle(tax included)
    <% end %>

At first I thought I forgot to close the tag, but it seems that it is different.

It was actually a very simple mistake.

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

I equated it with <% =%> even though I didn't actually see it in the view.

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

If you remove =, the contents of params that were displayed in a row disappeared. It was a new learning that if you add = to something that is not displayed in the view, this will happen.
