Mostly correct, yes.
For now you can ignore your #2, if I can figure out #1 I should be good
to go.
For #1, Ideally I would like to have a snippet that handles putting the
urls together. I know where in my hierarchy news pages will be, but I
wont necessarily know when someone has added a new project with news. I
would be easier to be able to do:
{pseudocode}<r:find url="projects"><r:children:each><if has child url
matches /news/ return url></r:children:each></r:find>
if that is not possible, but having a page "HOME" with a page part
"news_urls" /news;/project1/news;/project2/news;
and then saying
<r:aggregate urls='<r:find url="/home"><r:content
part="news_urls"/></r:find></r:aggregate>
would be sufficient.
If you're comfortable writing tags, I think this is what you need to do:
* Merge the code from the 2 sets below: 1 is from aggregate and the
other is from snippet
--- from standard_tags.rb > tag: snippet
tag 'snippet' do |tag|
if name = tag.attr['name']
if snippet = Snippet.find_by_name(name.strip)
tag.locals.yield = tag.expand if tag.double?
tag.globals.page.render_snippet(snippet)
else
raise TagError.new('snippet not found')
end
else
raise TagError.new("`snippet' tag must contain `name' attribute")
end
end
---- from aggregation_tags.rb > tag: aggregate
tag "aggregate" do |tag|
raise "`urls' attribute required" unless tag.attr["urls"]
urls = tag.attr["urls"].split(";").map(&:strip).reject(&:blank?).map
{ |u| clean_url u }
parent_ids = urls.map {|u| Page.find_by_url(u) }.map(&:id)
tag.locals.parent_ids = parent_ids
tag.expand
end
If you could just merge the 2, it should be possible to create:
* aggregate_snippet snippet_name="..." or modify aggregate to do:
You could try something like this (done from a lot of copy and paste, no
testing!)
tag "aggregate_snippet" do |tag|
raise "`snippet_name' attribute required" unless
tag.attr["snippet_name"]
if name = tag.attr['snippet_name']
if snippet = Snippet.find_by_name(name.strip) #snippet was found..
urls =
snippet.content.split(";").map(&:strip).reject(&:blank?).map { |u|
clean_url u }
parent_ids = urls.map {|u| Page.find_by_url(u) }.map(&:id)
tag.locals.parent_ids = parent_ids
tag.expand
end
You should be able to use this by doing:
<r:aggregate_snippet snippet_name="whatever">.........
</r:aggregate_snippet>
Hope this helps.
Cheers,
Mohit.
