我该如何缓存Django的staticfile破坏文件？

Question

I have a webpage which includes an image. I wish to cache bust that image using the ? technique. However, staticfiles encodes questionmarks as '%3F', so the path is no longer correct.

{% load staticfiles %}
<img src="{% static 'poll/img/test.jpg?v2' %}">

Gets compiled as.

<img src="/static/poll/img/test.jpg%3Fv2">

There is no test.jpg%3Fv2 file. So it doesn't show. Using static it works fine.

{% load static %}
<img src="{% static 'poll/img/test.jpg?v2' %}">

Get's compiled as expected. I want to use staticfiles rather than static as I serve my static files from a cloud service. Is there a way to prevent the encoding of my string path or a workaround of the problem?

Answer 1

To solve the encoding either write your own version of the static tag or simply move the parameters beyond the tag.

{% load staticfiles %}
<img src="{% static 'poll/img/test.jpg' %}?v2">
