Question

我正在尝试在索引页面上创建一个电子表格以显示带有复选框的项目，并且如果经过验证-复选框将被禁用，以便人们不会误勾选它。我想知道我应该使用控制器还是视图来实现？谢谢：你能帮忙吗？

在app / views / scooties_coupons / index.html.erb

<table class="table table-hover">

<h1>Scooties Coupons</h1>

<%= form_with(url: validate_coupons_path, method: 'patch') do |f| %>
  <table>
    <thead>
      <tr>
        <th>Valid</th>
        <th>Coupon</th>
        <th>Redeemed</th>
        <th>First name</th>
        <th>Surname</th>
        <th>email</th>
        <th>occupation</th>
        <th>validation</th>
        <th colspan="3"></th>
      </tr>
    </thead>

    <tbody>
      <% @scooties_coupons.each do |scooties_coupon| %>
        <tr>
          <td>
            <%= fields_for('scooties_coupons[]', scooties_coupon) do |cf|
              cf.check_box(:validated)
            end %>
          </td>
          <td><%= scooties_coupon.coupon %></td>
          <td><%= scooties_coupon.redeemed %></td>
          <td><%= scooties_coupon.first_name %></td>
          <td><%= scooties_coupon.surname %></td>
          <td><%= scooties_coupon.email %></td>
          <td><%= scooties_coupon.occupation %></td>

        </tr>
      <% end %>
    </tbody>
  </table>
  <%= f.submit %>
<% end %>

<br>

</table>

在app / controllers / scotties_coupons_controller.rb中：


def set_valid_coupons
  to_valid = params[:scooties_coupons].select do |id, attrs|
    attrs[:validated] == '1'
  end
  to_not_valid = params[:scooties_coupons].reject do |id, attrs|
    attrs[:validated] == '1'
  end
  ScootiesCoupon.transaction do
    ScootiesCoupon.where(id: to_valid.keys, validated: false).update_all(
      validated:true)
    ScootiesCoupon.where(id: to_not_valid.keys, validated: true).update_all(
      validated:false)
  end
  redirect_to action: :index, notice: 'Validations updated'
end

            <% if true %>
                SOMETHING HERE 
            <% else %>
              <%= fields_for('scooties_coupons[]', scooties_coupon) do |cf|
                cf.check_box(:validated)
              end %>

            <% end %>
          </td>
          <td><%= scooties_coupon.coupon %></td>
          <td><%= scooties_coupon.redeemed %></td>
          <td><%= scooties_coupon.first_name %></td>
          <td><%= scooties_coupon.surname %></td>
          <td><%= scooties_coupon.email %></td>
          <td><%= scooties_coupon.occupation %></td>

        </tr>
      <% end %>
    </tbody>
  </table>
  <%= f.submit %>
<% end %>
