html - Rails 从 Helper 模块返回多个 content_tags

Question

我编写了以下助手:

def section_to_html (block)
      case block[0].downcase
      when "paragraph"
        block.shift
        block.each do |value|
          return content_tag(:p, value)
        end
      end
  end

目前正在解析这些数组。

["paragraph", "This is the first paragraph."]
["paragraph", "This is the second.", "And here's an extra paragraph."]

它返回:

<p>This is the first paragraph.</p>
<p>This is the second.</p>

有没有办法累积content_tag？所以它返回:

<p>This is the first paragraph.</p>
<p>This is the second.</p>
<p>And here's an extra paragraph.</p>

我现在唯一的解决方案是改用部分。但是，一旦我开始向案例条件添加更多内容，情况就会变得非常困惑。

使用#concat:
