Betreff: custom templatetag that checks groups

 

Hi,

 

I want to create my own templatetag that returns true if a user is member of a certain group.

I did the following:

 

Created a package „templatetags“ in my app.

Wrote a module:

 

from django import template

register = template.Library()

 

def check(user):

    if str(user.groups.all()[0]) == "Timesheet-Boss":

        return True

    else:

        return False

 

Put this in my html:

 

{% load checkers %}

 

{{ check:user  }}

 

I get the following error:

 

Invalid filter: 'check'

Request Method:	GET
Request URL:	http://localhost:8000/
Django Version:	1.2.4
Exception Type:	TemplateSyntaxError
Exception Value:	Invalid filter: 'check'

 

 

What am i doing wrong ?!

 

Best regards
