How can I url-encode a translated block of text with variables?

I am trying to urlencode a translated block of text that contains variables in a Django (1.6.1) template. I need to do this because of a mailto link that contains a translated subject:

<a href="mailto:[email protected]?subject=_('Hello {{ username }}')|urlencode">Send email</a>

Except this code produces the following output:

<a href="mailto:[email protected]?subject=Hello%20%7D%7Dusername%7D%7D%20">Send email</a>

So, obviously, the username variable was not evaluated by the _() operator. If I'm not mistaken, the only translation tag that can evaluate variables is blocktrans.

So, what would be great would be to store the subject translation in a dedicated variable. Something like:

{% blocktrans as subject %}Hello {{ username }}{% endblocktrans %}
<a href="mailto:[email protected]?subject={{ subject|urlencode }}">Send email</a>

Except that "as" is not a valid argument for blocktrans.

I am aware that I could solve this with javascript. I am looking for a more "Djangonic" solution.

Try escaping the translation on the pinch brackets:

<a href="mailto:[email protected]?subject=_('Hello \{\{ username \}\}')|urlencode">Send email</a>

I hope this helps.

You probably have to do this outside of template. Either with templatetag or in view. In any case... Instead of:

<a href="mailto:[email protected]?subject=_('Hello {{ username }}')|urlencode">Send email</a>

you need something like this:

import urllib
d = {'subject':ugettext(u"Hello %s" % username)}

and change the subject part for 

value = urllib.urlencode(d)

'<a href="mailto:[email protected]?%s">Send email</a>' % value

If you are translating "hello" by the way, then you should probably consider translating "Send email" too :P
