如何在 Django 模板中将变量显示为 HTML？

Question

let's said that I have function

def func(request):
    a="Hello, <br> this is my first app"
    return render_to_response(
                            'home.html',
                            {'a':a, 'request':request},
                            context_instance=RequestContext(request)
                          )

when I load variable a in home.html as

{{a}}

I will get Hello, <br> this is my first app , how to present <br> as new line in django template ...??

Answer 1

Try this:

from django.utils.safestring import mark_safe


a = mark_safe("Hello, <br> this is my first app")

Django automatically escapes any HTML in your variables, so you need to mark it as a safestring.

Keep in mind, for example, that safestring + unsafestring = unsafestring. You can read more about it here

Answer 2

An easier way would be to use

{{a|safe}}

in the template itself.

Answer 3

在模板文件中使用 {{a|safe}}，而不是 {{a}}
