Why am I getting error: invalid filter 'customfilter' ?

Question

I have a custom module and need to create a custom template filter. I used this reference http://meta.osqa.net/questions/5528/can-a-forum-module-define-template-tags and created this setup:

in mymodule_tags.py:

from forum.templatetags.extra_tags import register
@register.filter
def customfilter(value):
    return 1 #will edit this to do something based on "value"

in startup.py:

from mymodule_tags import *

in mytemplate.html:

{% load extra_tags %}
{{ myvalue|customfilter }}

however, this just gets me the error: invalid filter 'customfilter'

Try changing your startup.py to this:

import mymodule_tags

Otherwise, that looks like it should work.

@Kevin Yank: that didn't fix it (btw, thanks for the reply). I looked over it several times now and I don't think I have any typos or things like that. mymodule_tags.py and startup.py should both be placed in my module's main folder, correct? I can't imagine why this isn't working.

I faced the same problems-- and figured out a solution. Does this answer work for you?

@Justin Grant thanks, but that doesn't seem to work either. I even checked out the latest osqa release to see if that helped. I have the exact problem you described: if my module is in the forum/templatetags folder everything works fine, but if its in my module's folder it doesn't work. I tried your solution, which seems like it should work, but it doesn't.
