rails - 使用段落返回输出用户输入? [英] rails - outputting user input with Paragraph Returns?

问题描述

我有一个 textarea 输入，允许用户输入多个段落，这意味着用户可以输出一个新行.

I have a textarea input that allows users to input in more than on paragraph, meaning the user can output a new line.

问题是当我从数据库中输出时，它全部缩小为一行?

Problem is when I output that from the database it's all shrunk into one line?

如何将新行变成 HTML 友好的新行，使其看起来像用户输入文本的方式?

How do I make that new line into an HTML friendly new line so it looks the way the user inputted the text?

谢谢

推荐答案

使用 simple_format 帮手.它用
或

Use the simple_format helper. It's replace all \n by <br /> or <p>

来自 API 的示例:

Examples from API :

 my_text = "Here is some basic text...\n...with a line break."

  simple_format(my_text)
  # => "<p>Here is some basic text...\n<br />...with a line break.</p>"

  more_text = "We want to put a paragraph...\n\n...right there."

  simple_format(more_text)
  # => "<p>We want to put a paragraph...</p>\n\n<p>...right there.</p>"

  simple_format("Look ma! A class!", :class => 'description')
  # => "<p class='description'>Look ma! A class!</p>"
