Use 'now' in django blocktrans?

Question

I'd like to add the year into a Django blocktrans - using the syntax below.

{% blocktrans with now|date:"Y" as copydate %}
     © {{ copydate }} Company
{% endblocktrans %}

This is similar to this existing Django ticket (http://code.djangoproject.com/ticket/3088), which apparently should work now but I can't get to work either.

In both cases the tag is simply not expanded, but the rest of the blocktrans renders fine.

Answer 1

The only way is to get your date in python and use date filter as Reiner proposes or define your own templatetag. You can create a little context processors to set date in your context.

def my_date(request):
  import datetime
  return {'my_date':datetime.datetime.now()}

and add this in settings.py

TEMPLATE_CONTEXT_PROCESSORS = DEFAULT_SETTINGS.TEMPLATE_CONTEXT_PROCESSORS + (
      'the_package_of_my_tiny_function.my_date',
      )

Use it in your templates like this:

   {% blocktrans with my_date|date:"Y" as copydate %}
      © {{ copydate }} Company
   {% endblocktrans %}

Don't forget to pass RequestContext as context_instance in your views

Here is the example.

Starting from Django 1.8, you can now use the {% now 'Y' as copydate %} syntax, so you should be able to do:

{% now 'Y' as copydate %}
{% blocktrans %}© {{ copydate }} Company{% endblocktrans %}

The now tag returns a formatted date as string matching the format passed. date probably needs a datetime/date object. So chaining these together wouldn't work.

I'm not even sure if you can use the now tag in the with statement, but try this.

{% blocktrans with now "Y" as copydate %}

now accepts the same format string as date. If this doesn't work either, my best bet would be to just pass the template a datetime.datetime.now() result, and use that instead of now.

{% blocktrans with my_date|date:"Y" as copydate %}
