Django: allow line break from textarea input
提问by barin
How do I allow line breaking in textarea input in django to later show this input on page?
如何允许在 django 中的 textarea 输入中换行以稍后在页面上显示此输入？

Replaces line breaks in plain text with appropriate HTML; a single newline becomes an HTML line break (<br />) and a new line followed by a blank line becomes a paragraph break (</p>).
用适当的 HTML 替换纯文本中的换行符；单个换行符成为 HTML 换行符 ( <br />)，新行后跟一个空行成为分段符( </p>)。
For example:
例如：
{{ value|linebreaks }}
If value is Joel\nis a slug, the output will be <p>Joel<br />is a slug</p>.
如果值为Joel\nis a slug，则输出将为<p>Joel<br />is a slug</p>.

Don't use {% autoescape off %}! Otherwise user controlled input may not get escaped, which is a security risk. As mentioned use linebreaks or linebreaksbr.
不要用{% autoescape off %}！否则用户控制的输入可能不会被转义，这是一个安全风险。如前所述，使用linebreaks 或 linebreaksbr。

I had a text area for user minimal custom input in the template and I wanted to keep whatever formatted text the user inserted to stay the same. The solution, I simply changed the Model variable to a TextField type. It even shows the user formatted text in the admin. :)
我在模板中有一个用于用户最小自定义输入的文本区域，我想保留用户插入的任何格式化文本以保持不变。解决方案，我只是将 Model 变量更改为 TextField 类型。它甚至在管理员中显示用户格式化的文本。:)
ex.
前任。
class Uadds(models.Model):
title = models.CharField(max_length = 50)
description = models.TextField(max_length = 1000)
title will not show line breaks, however, description will show them. I haven't tested this with a Rich Text Editor... Hope this helped.
title 不会显示换行符，但是 description 会显示它们。我还没有用富文本编辑器测试过这个......希望这会有所帮助。

Use {% autoescape off %} {{ your_variable }} {% endautoescape %}.
使用{% autoescape off %} {{ your_variable }} {% endautoescape %}.
