Hi all

I think I figured this nav puzzle out on a project many years ago but can't find my old code.

I want to make next and prev nav links in a blog story that would link to the previous story in the same category - ordered by cover date. There's not a way to use story->list() and Offset => -1 is there? If so it doesn't seem to be working for me.

here's what I have in the Blog story:


my ($next) = $story->list({
element_key_name => 'article',
category_id => $story->get_primary_category->get_id,
unexpired => 1,
publish_status => 1,
limit => 1,
exclude_id => $story->get_id,
cover_date_start => $story->get_cover_date,
Order => 'cover_date',
OrderDirection => 'DESC',
});



my ($prev) = $story->list({
element_key_name => 'article',
category_id => $story->get_primary_category->get_id,
unexpired => 1,
publish_status => 1,
limit => 1,
offset => -1,
exclude_id => $story->get_id,
cover_date_start => $story->get_cover_date,
Order => 'cover_date',
OrderDirection => 'ASC',
});

thanks
Dawn

You could get the next story with:
(...other search parameters...
cover_date_start => $story->get_cover_date,
Order => 'cover_date',
Limit => 1,
OrderDirection => 'ASC' )

And the previous story with:
(...other search parameters...
cover_date_end => $story->get_cover_date,
Order => 'cover_date',
Limit => 1,
OrderDirection => 'DESC' )

Hi Dawn,

How about this?


my ($next) = $story->list({
element_key_name => 'article',
category_id => $story->get_primary_category->get_id,
unexpired => 1,
publish_status => 1,
limit => 1,
exclude_id => $story->get_id,
cover_date_start => $story->get_cover_date,
Order => 'cover_date',
OrderDirection => 'ASC',
});



my ($prev) = $story->list({
element_key_name => 'article',
category_id => $story->get_primary_category->get_id,
unexpired => 1,
publish_status => 1,
limit => 1,
exclude_id => $story->get_id,
cover_date_end => $story->get_cover_date,
Order => 'cover_date',
OrderDirection => 'DESC',
});

thanks you guys.. I actually DID try that first but it didn't seem to be working.. so I thought me code was flawed.

But it was late.. and now I will try it again in the clear light of day.

oh so the trick is use cover_date_end ? I was mixing that up with expire_date.

from the docs Bric::Biz::Asset::Business::Story

cover_date_end
Returns a list of stories with a cover date on or before a given date/time.



thank you
Dawn
