Thanks again for all your help.
I believe I have something that is finally working:
class WideOrDeepNode(template.Node):
def __init__(self, photoobj, varname):
self.photoobj = photoobj
self.varname = varname
def render(self, context):
self.photoobj = resolve_variable(self.photoobj, context)
context[self.varname] = self.photoobj.width <=
self.photoobj.height
return ''
def do_get_wideordeep(parser, token):
"""
Checks to see if the photo is horizontal (and square) or
vertical. Will return '1' if it is vertical. Otherwise returns '0'.
Syntax::
{% get_wideordeep object.id [as varname] %}
"""
bits = token.contents.split()
if len(bits) == 2:
photoobj = bits[1]
varname = 'image_is_vertical'
elif len(bits) == 4:
photoobj = bits[1]
varname = bits[3]
else:
raise template.TemplateSyntaxError, "'%s' tag takes either one
or two arguments" % bits[0]
return WideOrDeepNode(photoobj,varname)
