Won't work. Django's template language is *not* Python, it's a
language on it's own.

This might be a solution, yes. But why not just populate your context
with relevant data, ie:
def myview(request, yadda):
author = get_author_someway()
date = get_date_somehow()
books = author.get_books_published_after(date)
context = dict(author=author, date=date, books=books)
return render_to_response("mytemplate.html", context)
> Then the call would be like so??
For a template tag ? Well, since you'll have to implement it by
yourself, the syntax is up to you. But just for the record, an
emerging convention for template tags that "insert" additional data in
the context is to end them with " as " to let the caller
specify the name under which the data must be known in the template.

I'd suggest:
{% get_books_published for after as
%}
Now you just have to write the compilation function and rendering
Node. Relevant doc is here:
http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#writing-custom-template-tags
Please feel free to come back here with more questions *once* you'll
have read the doc and started to write your custom tag - we'll be glad
to help further. Until then, anything I could add is already explained
in the doc.

sending a context to a template by calling a function with parameters.
Hello, I want to return a context of data to the template that contains information in the models. I want to pass in variables that dictate what is returned. Example: author1.get_books_published_after Then it grabs all the data via a method in the model and returns it. Should I instead use the custom template tags? Then the call would be like so?? Example: get_books_published_after Then it would return all the books for the author that was published after a certain date. Can someone explain?
