Since Hotwire was released, Rails scaffolds generate LISTS with CARDS, not a TABLE in index.html.erb.

To continue having tables in your scaffolds, paste this code into lib/templates/erb/scaffold/index.html.erb.tt within your Rails app.

If you are using tailwindcss-rails, you will also want to specify that you want to use your own template_engine:

# config/application.rb
    config.generators.template_engine = :erb

In this same way you can overwrite the default scaffold templates to include:

  • your own CSS styling
  • i18n
  • search, pagination (in scaffold views and controllers)

For example, you can try adding simple_form & bootstrap styling for your scaffolds by default.

Example of final result:

If you run the below command in your terminal, it will run a script to add styled *.html.erb scaffold templates to your app:

rm ./lib/templates/erb/scaffold/_form.html.erb
rails app:template LOCATION="https://blog.corsego.com/script-custom-scaffold-templates.txt"

Regenerating scaffold views for existing model based on attributes:

rails g erb:scaffold Post title content

Here’s how a bootstrap-styled scaffold template erb file can look:

<!-- lib/templates/erb/scaffold/index.html.erb -->
<h3>
  <div class="text-center">
    <%= plural_table_name.capitalize %>
    <div class="badge badge-info">
      <%%= @<%= plural_table_name%>.count %>
    </div>
    <%%= link_to "New <%= singular_table_name %>", new_<%= singular_table_name %>_path, class: 'btn btn-primary' %>
  </div>
</h3>
<div class="table-responsive">
  <table class="table table-striped table-bordered table-hover table-sm table-light shadow">
    <thead>
      <tr>
        <th>Id</th>
    	  <% attributes.each do |attribute| %>
        <th><%= attribute.human_name %></th>
        <% end %>
        <th>Actions</th>
      </tr>
    </thead>
    <tbody>
      <%% @<%= plural_table_name%>.each do |<%= singular_table_name %>| %>
        <%%= content_tag :tr, id: dom_id(<%= singular_table_name %>), class: dom_class(<%= singular_table_name %>) do %>
          <td><%%= link_to <%= singular_table_name %>.id, <%= singular_table_name %> %></td>
          <% attributes.each do |attribute| %>
            <td><%%= <%= singular_table_name %>.<%= attribute.name %> %></td>
          <% end %>
          <td>
            <%%= link_to 'Edit', edit_<%= singular_table_name %>_path(<%= singular_table_name %>), class: 'btn btn-sm btn-warning' %>
            <%%= link_to 'Destroy', <%= singular_table_name %>, method: :delete, data: { confirm: 'Are you sure?' }, class: 'btn btn-sm btn-danger' %>
          </td>
        <%% end %>
      <%% end %>
    </tbody>
  </table>
</div>
