Problem With Templatetags

[Showket Bhat]

Hi All,

I am using templatetags to create one tag.. I created the folder
templatetags and created 2 files in it.. __init__.py which is empty
and another temp_tags.py.. where i put one method

temp_tags.py
====================
from django import template
register = template.Library()
register.filter('lower', lower)

def lower(value): # Only one argument.
# "Converts a string into all lowercase"
return value.lower()

=========================
template2.html
=========================

{% load temp_tags %}

This will print my name in lowercase: {{ name|lower }}

============================

I ve not inserted anything in setting.py regarding templatetags and I
am getting this error


=============================

TemplateSyntaxError at /view2/

'temp_tags' is not a valid tag library: Template library temp_tags not

Hi, I m new in django too but i ll try to help you.

In your tem_tag.py can you add : @register.simle_tag just before you def you tag, just like this :

@register.simle_tag

def my_tag():

    return blablabla

[Showket Bhat]

[Juergen Schackmann]

have you added the application that holds your template tag to settings.py?

Actually (according to your code snippet) a filter.

s/method/function/

If this is your exact real code, you should get a NameError on the
third line, where you try to register your filter function before it's
defined.


Also and FWIW, you don't really need such a filter, just use
{{ name.lower }} in your template.

The django app containing your templatetags package needs to be
registered in settings.INSTALLED_APPS.

That's nice from you, but you should possibly read the post you're
answering a bit more carefully:

The OP is actually defining a template filter, not tag, so
register.simple_tag is not going to help...

That's actually a __init__.py (*not* .pyc). And yes, the OP did and
explicitely mentionned it.

Err... is this actually 'myTag.py' or 'temp_tags.py' ?

[nicolas HERSOG]

https://docs.djangoproject.com/en/dev/howto/custom-template-tags/

It was just an exemple I gave to Showket, and you'r right, we don t need a __init__.pyc in the templateTag folder. 

I tried to help Showket but i m quite too unexperiment for it yet :)
