A possible solution would be the children:each to count the number of
children pages and automatically set it as the value for the limit
param.
I think it would be a very fast and easy solution.

Supose I've got 6 children pages, if I write:
r:children:each offset=3.../r:childen:each
it behaves like a pure
r:children:each.../r:childen:each
showing all 6 pages.
But if I write:
r:children:each limit=6 offset=3.../r:childen:each
it works correctly, showing only the last three.
Is it correct?
I recently ran into this confusing problem too.
Here are the relevant specs:
http://github.com/radiant/radiant/tree/master/spec/models/standard_tags_spec.rb#L90-96
which test children:each given a limit, or an offset with a limit. But there
is no spec for an offset without a limit. When I saw this, I tried adding a
limit to my children:each tag (which had only an offset), and reached the
same conclusion as Gabriel.
Page.find(:all, :offset = 3) returns all pages.
This is essentially what the children:each does (scoped to a particular
page)
If this is incorrect behavior, it's with ActiveRecord::Base
As Jim points out, the behaviour is defined at the level of ActiveRecord.
I wonder if an interim solution might be for the children:each tag to set a
default limit of a very high number (such as 10,000). This way, you could
call:
r:children:each offset=3.../r:childen:each
which would run something like:
Page.find(:all, :offset = 3, :limit = 1)
and produce the expected effect of returning all pages after the first 3.
(As long as you have less than 1 pages!)
Any thoughts?
