How do you place a variable inside a template tag's argument?

问题

With Django media I could do the following:

{% for language in LANGUAGES %}
  <script type="text/javascript" src="{{ MEDIA_URL }}app/js/jquery.ui.datepicker.{{ language.0 }}.js"></script>
{% endfor %}

Now, I'd like to switch to static files. However this (obviously) does not work any more:

{% for language in LANGUAGES %}
  <script type="text/javascript" src="{% static "app/js/jquery.ui.datepicker.{{ language.0 }}.js" %}"></script>
{% endfor %}

Is there some clean way to achieve what I'm trying to do?

[ I want to switch for consistency, because the admin and many third-party apps I'm using have switched. Also, I'm worried that the Django media will be deprecated sometime in the future. ]

回答1:

You have two options. First one, as suggested, use {{ STATIC_URL }}:

{% for language in LANGUAGES %} 
<script type="text/javascript"
  src="{{STATIC_URL}}app/js/jquery.ui.datepicker.{{ language.0 }}.js"
></script> 
{% endfor %}

Alternatively, as {% static %} only prefixes its argument but does not require the path to be actually valid:

{% for language in LANGUAGES %} 
<script type="text/javascript"
  src="{% static "app/js/jquery.ui.datepicker" %}.{{ language.0 }}.js"
></script>                                 
{% endfor %}
