html - rails render helper 返回带有 '\n' 作为新行的 p 标签

Question

我得到的这个字符串里面有'\n'，我想在有'\n'的地方显示一个新行，而不是显示原始字符串

在 fruits.description 里面

fruits.description: 'This is an red apple \n It is also very sweet'

我的渲染辅助方法

def get_description(fruits)
  if fruits.type == 'apple'
    haml_tag 'p', fruits.description, {id: fruits.id}
  end
end

我想让字符串显示成这样

This is an red apple
It is also very sweet

Answer 1

尝试 simple_format , 这将添加 <p>标记并翻译 \n至 <br>等

具体来说:

Two or more consecutive newlines(\n\n) are considered as a paragraph and wrapped in <p> tags. One newline (\n) is considered as a linebreak and a <br /> tag is appended.
