Fixed! I tried putting the contents of my previous templatetags in
another directory and it worked. Seems silly, though. Anyhow, now I
have:
project/templatetags/__init__.py
project/templatetags/templatetags/__init__.py
project/templatetags/templatetags/general_tags.py
Also, in case anyone closely scans the code above, I've fixed the
errors in general_tags.py and the tag works dandy!
New general_tags.py:
from django.template import Node, NodeList, resolve_variable
from django.template import TemplateSyntaxError, VariableDoesNotExist
from django.template import Library
register = Library()
class IfGreaterThanNode(Node):
def __init__(self, var1, var2, nodelist_true, nodelist_false):
self.var1, self.var2 = var1, var2
self.nodelist_true, self.nodelist_false = nodelist_true,
nodelist_false
def __repr__(self):
return "<IfGreaterThanNode>"
def render(self, context):
try:
val1 = resolve_variable(self.var1, context)
except VariableDoesNotExist:
val1 = None
try:
val2 = resolve_variable(self.var2, context)
except VariableDoesNotExist:
val2 = None
if (val1 > val2):
return self.nodelist_true.render(context)
return self.nodelist_false.render(context)
def do_ifgreaterthan(parser, token):
bits = list(token.split_contents())
if len(bits) != 3:
raise TemplateSyntaxError, "%r takes two arguments" % bits[0]
end_tag = 'end' + bits[0]
nodelist_true = parser.parse(('else', end_tag))
token = parser.next_token()
if token.contents == 'else':
nodelist_false = parser.parse((end.tag,))
parser.delete_first_token()
else:
nodelist_false = NodeList()
return IfGreaterThanNode(bits[1], bits[2], nodelist_true,
nodelist_false)
def ifgreaterthan(parser, token):
"""

return do_ifgreaterthan(parser, token)
ifgreaterthan = register.tag(ifgreaterthan)
