yesod-pagination's Introduction

yesod-pagination

(yesod-paginate is taken)

This package makes it pretty simple to paginate records.

You'll probably want to use the function paginateWith, which takes an esqueleto query and gives you Handler (Page r). The returned Page object might have next page and previous page links (pre-rendered).

The most trivial example of an esqueleto query is return (paginate is basically paginateWith return). This one is a bit less trivial.

import Import
import Yesod.Paginate

getMessagesR :: Handler Html
getMessagesR = do
    myMessages <- paginateWith $ \msg -> do
        orderBy [asc (msg ^. MsgCreatedAt)]
        return msg

    defaultLayout $(widgetFile "message-list")

For a lesson on how to write esqueleto queries, see the haddocks.

yesod-pagination's Issues

Add an additional option to obtain the full list of pages and last page if explicitly requested?

Currently the pagination restricts to first, prev and next, which makes a lot of sense in minimizing the queries. Would it make sense to offer a lazy computation of all page numbers as well as the last page, if explicitly requested?

I envision to extend Page to include previousPages :: [Int], currentPage :: Int, nextPages :: [Int] and lastPage :: Maybe route. For these computation an additional count would be sufficient, I think, which again would only be needed when requested and hence due to the laziness only be computed when requested, no?
