我如何在django中使用字符串作为html?其中包括django的内联html

Question

例如:

str = "<b>Hello<b> this string also includes my {{myvariable}} {%if myvariable%} and its true {%endif%}"

我知道|safe过滤器存在，但它不适用于内联html，仅适用于html。autoescape off也一样。

如果有人能帮助我，我会很高兴的。D

Answer 1

您必须决定是否要在Python中执行此格式化并将其传递给模板，还是在模板中。此外，您是否希望对myvariable中的特殊字符进行转义

模板中:

<b>Hello<b> this string also includes my {{myvariable}} {%if myvariable%} and its true {%endif%}"

或避免转义

<b>Hello<b> this string also includes my {{myvariable|safe}} {%if myvariable%} and its true {%endif%}"

在Python中使用转义

annitt = "and its true " if myvariable else ""
safestr = format_html( 
"<b>Hello<b> this string also includes my {} {}", myvariable, anitt)

没有逃避

annitt = "and its true " if myvariable else ""
unsafestr = f"<b>Hello<b> this string also includes my {myvariable} {anitt}"
safestr = mark_safe( unsafestr)

传递给模板，其中，{{safestr}}

像这样使用

from django.utils.safestring import mark_safe
str = "<b>Hello<b> this string also includes my {{myvariable}} {%if myvariable%} and its true {%endif%}"
str = mark_safe(str)

对于所有需要看到的，这里有一个教程:

首先需要你的字符串:

str = '{{ value.passed }}{% if not value.passed %}. Thats not good, Look here for help <a href="https://{{url}}" target="_blank">Google</a>.{% endif %}'

，然后使用渲染函数和上下文来影响模板:

from django.template import Context, Template
t = Template(str)
dict = {'value':{'passed': False} ,'url': "www.google.com"}
newstr = (t.render(Context(dict)))

最后但并非最不重要的是使用一种方法来执行HTML代码

我现在使用这个方法(感谢@Dad)

from django.utils.safestring import mark_safe
str = mark_safe(newstr)
