Dan, I don't think context_processors will do any good, since I'd have
to load each product and its price on the context.
imagine a model:
Product(models.Model):
price = models.FloatField(...)
and a
Currency(models.Model):
code = models.CharField(maxlength=3) # USD, YEN, etc
factor = models.FloatField(...) # defines the difference to euro
and in a template I do:
{% for product in product_list %}
{{ product.name }}
{{ product.price|currency:"EUR" }}
...
{% endfor %}
All that does, is take the product price and multiply it with the
currency's factor.
I've already set up a context_processor which registers CURRENCY,
which the user can set his preferred currency (EUR, USD, etc).
But since I cannot do {{ product.price|currency:{{ CURRENCY }} }}, as
only strings are allowed, and filters don't have access to context
variables or the request session, I am wondering if middleware is the
answer here. But I have no prior middleware experience :)
Maybe a template tag would do it, not sure if it gets access to the
request.
