class Paginator(object_list, per_page, orphans=0, allow_empty_first_page=True, error_messages=None)Link to this definition#

Feidhmíonn leathanaigh cosúil le seicheamh de:class: Leathanach nuair a úsáidtear `len () ``nó é ag athrá go díreach.

Paginator.object_listLink to this definition#

Riachtanach. Liosta, tuple, QuerySet, nó réad eile atá inslithe le modh count () ``nó ``__len__ (). Le haghaidh leathanaigh chomhsheasmhach, ba cheart QuerySets a ordú, m.sh. le an:meth: ~django.db.models.query.queryset.order_by clásal nó le clásal réamhshocraithe:attr: ~Django.db.Models.Options.Ordering ar an tsamhail.

Paginator.per_pageLink to this definition#

Riachtanach. An líon uasta na míreanna atá le cur san áireamh ar leathanach, gan dílleachtaí san áireamh (féach an argóint roghnach: attr: ~Paginator.orphans thíos).

Paginator.orphansLink to this definition#

Optional. Use this when you don't want to have a last page with very few items. If the last page would normally have a number of items less than or equal to orphans, then those items will be added to the previous page (which becomes the last page) instead of leaving the items on a page by themselves. For example, with 23 items, per_page=10, and orphans=3, there will be two pages; the first page with 10 items and the second (and last) page with 13 items. orphans defaults to zero, which means pages are never combined and the last page may have one item. orphans should be less than the per_page value.

Paginator.allow_empty_first_pageLink to this definition#

Optional. Whether or not the first page is allowed to be empty. If False and object_list is empty, then an EmptyPage error will be raised.

Paginator.error_messagesLink to this definition#

Ligeann an argóint error_messages duit na teachtaireachtaí réamhshocraithe a ardóidh an paginator a shárú. Pas isteach i bhfoclóir le heochracha a mheaitseálann leis na teachtaireachtaí earráide is mian leat a shárú. Is iad na heochracha teachtaireachta earráide atá ar fáil ná: invalid_page, min_page`, agus no_results.

Mar shampla, seo an teachtaireacht earráide réamhshocraithe:

Python console

>>> from django.core.paginator import Paginator
>>> paginator = Paginator([1, 2, 3], 2)
>>> paginator.page(5)
Traceback (most recent call last):
  ...
EmptyPage: That page contains no results

Agus seo teachtaireacht earráide saincheaptha:

Python console

>>> paginator = Paginator(
...     [1, 2, 3],
...     2,
...     error_messages={"no_results": "Page does not exist"},
... )
>>> paginator.page(5)
Traceback (most recent call last):
  ...
EmptyPage: Page does not exist

AsyncPaginator classLink to this heading#

class AsyncPaginator(object_list, per_page, orphans=0, allow_empty_first_page=True, error_messages=None)Link to this definition#

Asynchronous version of Paginator.

AsyncPaginator has the same attributes and signatures as Paginator, with the following exceptions:

• The attribute Paginator.count is supported as an asynchronous method AsyncPaginator.acount().

• The attribute Paginator.num_pages is supported as an asynchronous method AsyncPaginator.anum_pages().

• The attribute Paginator.page_range is supported as an asynchronous method AsyncPaginator.apage_range().

AsyncPaginator has asynchronous versions of the same methods as Paginator, using an a prefix - for example, use await async_paginator.aget_page(number) rather than paginator.get_page(number).

Aicme LeathanachLink to this heading#

De ghnáth ní thógfaidh tú rudaí Page de láimh - gheobhaidh tú iad trí:class: Paginator a athrá, nó trí:meth: Paginator.page a úsáid.

class Page(object_list, number, paginator)Link to this definition#

Feidhmíonn leathanach cosúil le seicheamh de:attr: Page.Object_List nuair a úsáidtear `len () ``nó ag athrá go díreach é.

AsyncPage classLink to this heading#

class AsyncPage(object_list, number, paginator)Link to this definition#

Asynchronous version of Page.

AsyncPage has the same attributes and signatures as Page, as well as asynchronous versions of all the same methods, using an a prefix - for example, use await async_page.ahas_next() rather than page.has_next().

AsyncPage has the following additional method:

aget_object_list()Link to this definition#

Returns AsyncPage.object_list as a list. This method must be awaited before AsyncPage can be treated as a sequence of AsyncPage.object_list.

EisceachtaíLink to this heading#

exception InvalidPageLink to this definition#

Aicme bonn le haghaidh eisceachtaí a ardaítear nuair a chuirtear uimhir leathanaigh neamhbhailí ar phaginator.

Ardaíonn an modh: Meth: Paginator.page eisceacht mura bhfuil an leathanach iarrtha neamhbhailí (ie nach sláimhir) nó nach bhfuil aon rudaí ann. Go ginearálta, is leor an eisceacht Invalidpage a ghabháil, ach más mian leat níos mó gráinneachta, is féidir leat ceachtar de na heisceachtaí seo a leanas a ghabháil:

exception PageNotAnIntegerLink to this definition#

Ardaítear nuai:meth: ~Paginator.page tugtar luach nach sláimhir é.

exception EmptyPageLink to this definition#

Ardaítear nuai:meth: ~Paginator.page tugtar luach bailí ach níl aon rud ann ar an leathanach sin.

Is fo-aicmí iad an dá eisceacht de:exc: InvalidPage, ionas gur féidir leat iad a láimhseáil le ach amháin InvalidPage.
