I am trying to set up a templatetag that will give me a variable to
use
in templates so we can modify our presentation of stories depending
upon
whether the accompanying photo is horizontal or vertical. I am using
0.91 EllingtonCMS.
I've made a templatetag in /ellington/media/photos.py that looks like
this:
class WideOrDeepNode(CachedNode):
def __init__(self, photoobj, varname):
self.photoobj = photoobj
self.varname = varname
self.cache_timeout = 180
def get_cache_key(self, context):
return
"ellington.media.templatetags.photos.do_get_wideordeep:%s" % (SITE_ID)
def get_content(self, context):
if self.photoobj.width <= self.photoobj.height:
context[self.varname] = '0'
else:
context[self.varname] = '1'
return ""
def do_get_wideordeep(parser, token):
"""
Checks to see if the photo object's width is greater than its
length
and will return '0' if it is. Otherwise returns '1'.
Syntax::
{% get_wideordeep object.id [as varname] %}
"""
bits = token.contents.split()
if len(bits) == 2:
photoobj = bits[1]
varname = 'imageflag'
elif len(bits) == 4:
photoobj = bits[1]
varname = bits[3]
else:
raise template.TemplateSyntaxError, "'%s' tag takes either one
or two arguments" % bits[0]
return WideOrDeepNode(photoobj,varname)
on the template, here is how I am asking for it:
{% get_wideordeep homepage.get_piece_dict.lead_story.get_lead_photo
as
imageflag %}
{% ifequal imageflag 0 %}
<h1>This story's image is square or wider than deeper<br /><a
href="{{
homepage.get_piece_dict.lead_story.get_absolute_url }}">{{
homepage.get_piece_dict.lead_story.headline }}</a></h1>
<p>{% if
homepage.get_piece_dict.lead_story.get_lead_photo.get_photo_url %} <a
href="{{ homepage.get_piece_dict.lead_story.get_absolute_url }}">
<img
style="max-height:190px;padding-left:5px;float:right;border-width:
5px;border-color:#ffffff;"
border=3 bordercolor="white" src="{{
homepage.get_piece_dict.lead_story.get_lead_photo.get_photo_url|
thumbnail:"180"
}}"></a>{% endif %}
{% if homepage.get_piece_dict.lead_story.tease %} {{
homepage.get_piece_dict.lead_story.tease }}{% endif %} </p>
{% endifequal %}
{% endif %}
the results I get are "AttributeError at /homepage/dmtest/
'str' object has no attribute 'width'"
the problem line seems to be this one:
if self.photoobj.width <= self.photoobj.height:
this code is also at dpaste -- http://dpaste.com/122889/
Am I going about this all wrong?
