Kaminari ordered scope

Kaminari pagination not (always) showing

by rolf

The strangest thing...I paginate a scope with a total of, say 100 records. It works fine, except with a few people...It looks like kaminari calculates the need to add pagination-links by looking at the amount of records on the page it is showing, and returns early when this is less then the specified per-page-amount. 

return @total_count = (current_page - 1) * limit_value + 
 @records.length if @records.any? && (@records.length < limit_value)

(from "kaminari/kaminari-activerecord/lib/kaminari/activerecord/active_record_relation_methods.rb")

Since I could not find the time to solve this, I found a workaround by adding total_pages: @total_pages in the call for te pagination-helper. This @total_pages-variable is set the controller. It takes an extra , simple sql-query to find the total amount of records, divided by :per_page. I think it diasables kaminari's solution to speed things up, but, at least it will show all my records and links...

happy days ;-)

easy and concise versioning by the app_verion gem

by rolf

Started looking for an easy way to version my applications a few years ago. Bumped into the app_version-gem, which by then was pretty basic. For convenience reasons, I added a few rake tasks. When I recently looked at it again, I found the tests not working anymore, and more things to do...
