I need to pass a user id to a template tag.
After reading this: http://groups.google.com/group/django-users/
browse_thread/thread/96fe34b4561415dc/b7aba25f22bdd261?
lnk=gst&q=template+tags+variable&rnum=1#b7aba25f22bdd261
I came up with:
class SongListNode(template.Node):
def __init__(self, artist, varname):
self.artist, self.varname = artist, varname
def __repr__(self):
return "<Song Node>"
def render(self, context):
artist=self.artist.resolve(context)
context[self.varname] = Song.objects.filter(artist=artist)
#context[self.varname] = [self.artist]
return ''
class DoGetSongList:
"""
{% get_song_list as song_list %}
"""
def __init__(self, tag_name):
self.tag_name = tag_name
def __call__(self, parser, token):
bits = token.contents.split()
if len(bits) != 4:
raise template.TemplateSyntaxError, "'%s' tag takes three
arguments" % bits[0]
if bits[2] != "as":
raise template.TemplateSyntaxError, "second argument to
'%s' tag must be 'as'" % bits[0]
#return SongListNode(bits[1], bits[3])
return SongListNode(parser.compile_filter(bits[0]), bits[3])
register.tag('get_song_list', DoGetSongList('get_song_list'))
But no love. Suggestions?
