Keith,
This didn't work.
I'm going to work around it by doing:
<r:anothertag id='1' />
<r:yetanothertag id='1' />
for the moment... but it's not going to work in the long run... is
there a way to force/pass or create your own variables?
e.g
tag "mytag" do |tag|
if tag.attr["id"]
tag.locals.gallery = Gallery.find_by_id tag.attr["id"]
tag.expand { "id" => "1"}
end
...or...
tag "mytag" do |tag|
if tag.attr["id"]
tag.locals.my_gallery = Gallery.find_by_id tag.attr["id"]
tag.expand
end
...or...
tag "mytag" do |tag|
if tag.attr["id"]
tag.globals.gallery = Gallery.find_by_id tag.attr["id"]
tag.expand
end
Thanks in advance,
-Adam

You need to call the id in both tags. I know it is a little
counterintuitive, but the id tag is not being passed to the first
tag, just the second. I banged my head on this for a few days, try
it like this:
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|
gallery = Gallery.find_by_id tag.attr["id"] || tag.locals.gallery
gallery.name
end
This should work, but I haven't tested it, so I make no promises.
You may want to add a some sort of error handling in there in case
no id is found.

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
