Question

我有一个来自rails应用程序的数组，我得到以下数组。

[
  #<InvoiceDetail id: 66018858, invoice_id: 108855, package_id: 21008265, tracking_num: "1Z1Y81420342195332", base_charge: #<BigDecimal:7fed215e7188,'0.857E1',18(18)>, discount: #<BigDecimal:7fed215e70e8,'-0.308E1',18(18)>, created_at: "2012-07-30 15:33:43", updated_at: "2013-02-27 15:31:16", type_id: 54, transaction_date: "2012-07-23", gl_code: nil, division: nil>,

我想将这些数据解析成一个html表。 Rails还不是很新，也不知道从哪里开始。

编辑：

以下是我希望看到的表格。

       <table class="table table-condensed">
          <thead>
            <tr>
              <th>Invoice Id</th>
              <th>Package Id</th>
              <th>Tracking Number</th>
              <th>Base Charge</th>
              <th>Discount</th>
              <th>Type Id</th>
              <th>Transaction Date</th>
              <th>Gl Code</th>
              <th>Division</th>
            </tr>
          </thead>
          <tbody>
            <tr>
              <td>108855</td>
              <td>21008265</td>
              <td>1Z1Y81420342195332</td>
              <td>8</td>
              <td>-3</td>
              <td>54</td>
              <td>2012-07-23</td>
              <td>nil</td>
              <td>nil</td>
            </tr>
          </tbody>
        </table>

Answer 1

对于相同对象的通用列表，您可以选择（未测试）

之类的内容

<table>
  <thead>
    <tr>
      <% @array.first.attributes.each do |attr| %>
        <th><%= attr.titlelize %></th>
      <% end %>
    </tr>
  </thead>
  <tbody>
    <% @array.each do |x| %>
      <tr>
        <% x.attributes.each do |attr| %>
          <td><%= x[attr] %></td>
        <% end %>
      </tr>
    <% end %>
  </tbody>
</table>

或简单使用datagrid gem

ps。我在用户举例说明他希望他的桌子看起来像之前写了这个答案。对于那个确切的表，请查看@ankita answer。

fotanus的回答是正确的。但是如果您希望列按特定顺序排列，请使用此

<table class="table table-condensed">
      <thead>
        <tr>
          <th>Invoice Id</th>
          <th>Package Id</th>
          <th>Tracking Number</th>
          <th>Base Charge</th>
          <th>Discount</th>
          <th>Type Id</th>
          <th>Transaction Date</th>
          <th>Gl Code</th>
          <th>Division</th>
        </tr>
      </thead>
      <tbody>
        <% @invoice_details.each do |invoice_detail| %>
          <tr>
            <td><%= invoice_detail.id %></td>
            <td><%= invoice_detail.package_id %></td>
            <td><%= invoice_detail.tracking_number %></td>
            <td><%= invoice_detail.base_charge %></td>
            <td><%= invoice_detail.discount %></td>
            <td><%= invoice_detail.type_id %></td>
            <td><%= invoice_detail.transaction_date %></td>
            <td><%= invoice_detail.gl_code %></td>
            <td><%= invoice_detail.division %></td>
          </tr>
        <% end %>
      </tbody>
    </table>

注意：假设列名称。
