Pagination

Le vrai pouvoir de la pagination Hugo brille quand elle est combinée avec la fonction where et ses opérateurs de type SQL : first, last, and after. Vous pouvez même ordonner le contenu de la façon que vous aviez l’habitude de faire avec Hugo.

Configurer la Pagination

La pagination peut être configurée dans votre configuration de site:

Paginate

default = 10. Ce réglage peut être annulé dans le modèle.

PaginatePath

default = page. Vous permet de régler un chemin différent pour vos pages de pagination.

Setting Paginate to a positive value will split the list pages for the homepage, sections and taxonomies into chunks of that size. But note that the generation of the pagination pages for sections, taxonomies and homepage is lazy — the pages will not be created if not referenced by a .Paginator (see below).

PaginatePath is used to adapt the URL to the pages in the paginator (the default setting will produce URLs on the form /page/1/.

List Paginator Pages

There are two ways to configure and use a .Paginator:

1. The simplest way is just to call .Paginator.Pages from a template. It will contain the pages for that page.
2. Select a subset of the pages with the available template functions and ordering options, and pass the slice to .Paginate, e.g. {{ range (.Paginate ( first 50 .Data.Pages.ByTitle )).Pages }}.

For a given Page, it’s one of the options above. The .Paginator is static and cannot change once created.

The global page size setting (Paginate) can be overridden by providing a positive integer as the last argument. The examples below will give five items per page:

• {{ range (.Paginator 5).Pages }}
• {{ $paginator := .Paginate (where .Data.Pages "Type" "post") 5 }}

It is also possible to use the GroupBy functions in combination with pagination:

{{ range (.Paginate (.Data.Pages.GroupByDate "2006")).PageGroups  }}

Construire la Navigation

The .Paginator contains enough information to build a paginator interface.

The easiest way to add this to your pages is to include the built-in template (with Bootstrap-compatible styles):

{{ template "_internal/pagination.html" . }}

The following example shows how to create .Paginator before its used:

{{ $paginator := .Paginate (where .Data.Pages "Type" "post") }}
{{ template "_internal/pagination.html" . }}
{{ range $paginator.Pages }}
   {{ .Title }}
{{ end }}

Without the where filter, the above example is even simpler:

{{ template "_internal/pagination.html" . }}
{{ range .Paginator.Pages }}
   {{ .Title }}
{{ end }}

If you want to build custom navigation, you can do so using the .Paginator object, which includes the following properties:

PageNumber

The current page’s number in the pager sequence

URL: The relative URL to the current pager

Pages: The pages in the current pager

NumberOfElements

The number of elements on this page

HasPrev

Whether there are page(s) before the current

Prev

The pager for the previous page

HasNext

Whether there are page(s) after the current

Next

The pager for the next page

First

The pager for the first page

Last

The pager for the last page

Pagers

A list of pagers that can be used to build a pagination menu

PageSize

Size of each pager

TotalPages

The number of pages in the paginator

TotalNumberOfElements

The number of elements on all pages in this paginator

Information Supplémentaire

The pages are built on the following form (BLANK means no value):

[SECTION/TAXONOMY/BLANK]/index.html
[SECTION/TAXONOMY/BLANK]/page/1/index.html => redirect to  [SECTION/TAXONOMY/BLANK]/index.html
[SECTION/TAXONOMY/BLANK]/page/2/index.html
....
