Hi All!
I've written a custom template tag, but I get the error:
'reservationtags' is not a valid tag library: Could not load template
library from django.templatetags.reservationtags, No module named
reservationtags
I've looked in the archives and have tried everything I know so far:
1. templatetags directory is in the same level as models.py
2. templatetags has two files: __init__.py and reservationtags.py
3. I ran python manage.py shell, and executed:
from pennysaver.reservations.templatetags import reservationtags
and received no error.
4. reservationtags.py has: register = template.Library() and
register.tag('columnize', do_columnize)
For good measure, here's my code:
from django import template
register = template.Library()
def do_columnize(parser, token):
nodelist = parser.parse(('endcolumnize',))
parser.delete_first_token()
#Get the number of columns, default 1
try:
tag_name, columns, row_class, cell_class =
token.contents.split(None, 3)
except ValueError:
columns = 1
return ColumnizeNode(nodelist, columns)
class ColumnizeNode(template.Node):
def __init__(self, nodelist, columns):
self.nodelist = nodelist
self.columns = columns
self.counter = 1
def render(self, context):
self.counter += 1
if (self.counter > self.columns):
self.counter = 1
if (self.counter == 1):
output = '<tr'
if self.row_class:
output += ' class="%s">' % self.row_class
else:
output += '>'
output += '<td'
if self.cell_class:
output += ' class="%s">' % self.cell_class
else:
output += '>'
output += self.nodelist.render(context)
if (self.counter == self.columns):
output += '</tr>'
return output
register.tag('columnize', do_columnize)
Thanks for any help!
Corey
