Hey all,
I'm helping Andrea Franz work on his fantastic Gallery Extension:
http://darcs.bigchieflabs.com/radiant/extensions/gallery/
(download with 'darcs' - http://darcs.net)
Anyway I'm trying to add some globally available tags to it:
There is a Model declared thus:
class Gallery < ActiveRecord::Base
has_many :items,
:class_name => 'GalleryItem'
<snip>
end
And I have made a module in the extension /lib called gallery_tags.rb
which contains this (fake example)...
module GalleryTags
#tags available globally, not just on GalleryPages
include Radiant::Taggable
tag "mytag" do |tag|
if tag.attr["id"]
tag.locals.gallery = Gallery.find_by_id tag.attr["id"]
tag.expand
end
tag "anothertag" do |tag|
tag.locals.gallery.name
end
<snip>
end
added to the extension with:
def activate
admin.tabs.add "Galleries", "/admin/gallery", :after =>
"Layouts", :visibility => [:all]
Page.send :include, GalleryTags
end
yet when I do this in a page:
<r:mytag id='1'>
<r:anothertag>
</r:mytag>
I get this:
You have a nil object when you didn't expect it! The error occurred
while evaluating nil.name
It seems that tag.locals.gallery is being set to nil in between the
tag calls... I can't work out why because other extensions seem to do
similar things... it's very confusing.
Any help much appreciated.
Thanks,
-Adam
