Thanks for the encouragement, Alex. This was so easy, it should be a
first lesson in how to write a custom tag. It took about 15 minutes
and worked the first time!
from django import template
register = template.Library()
@register.tag(name="eval")
def do_eval(parser, token):
try:
tagName, variableName = token.split_contents()
except ValueError:
raise template.TemplateSyntaxError("%r requires a single
argument: the name of the variable to evaluate as the body of a
template" % tagName)
return EvalNode(variableName)
class EvalNode(template.Node):
def __init__(self, variableName):
self.variableName = variableName
def render(self, context):
t = template.Template(context[self.variableName])
return t.render(context)
