Django provides a few classes that help you manage paginated data -- that is,\ndata that's split across several pages, with "Previous/Next" links. These\nclasses live in django/core/paginator.py.
\nPaginator classLink to this heading#Required. A list, tuple, QuerySet, or other sliceable object with a\ncount() or __len__() method. For consistent pagination,\nQuerySets should be ordered, e.g. with an\norder_by() clause or with a default\nordering on the model.
Required. The maximum number of items to include on a page, not including\norphans (see the orphans optional argument below).
Optional. Use this when you don't want to have a last page with very few\nitems. If the last page would normally have a number of items less than or\nequal to orphans, then those items will be added to the previous page\n(which becomes the last page) instead of leaving the items on a page by\nthemselves. For example, with 23 items, per_page=10, and orphans=3,\nthere will be two pages; the first page with 10 items and the second\n(and last) page with 13 items. orphans defaults to zero, which means\npages are never combined and the last page may have one item.
Optional. Whether or not the first page is allowed to be empty. If\nFalse and object_list is empty, then an EmptyPage error will\nbe raised.
Returns a Page object with the given 1-based index, while also\nhandling out of range and invalid page numbers.
If the page isn't a number, it returns the first page. If the page number\nis negative or greater than the number of pages, it returns the last page.
\nRaises an EmptyPage exception only if you specify\nPaginator(..., allow_empty_first_page=False) and the object_list is\nempty.
Returns a Page object with the given 1-based index. Raises\nInvalidPage if the given page number doesn't exist.
Jumlah angka obyek, di semua halaman.
\n\nJumlah angka halaman
\nA 1-based range iterator of page numbers, e.g. yielding [1, 2, 3, 4].
Page classLink to this heading#You usually won't construct Page objects by hand -- you'll get them using\nPaginator.page().
A page acts like a sequence of Page.object_list when using\nlen() or iterating it directly.
Mengembalikan True jika ada halaman selanjutnya.
Mengembalikan True jika ada halaman sebelumnya.
Returns True if there's a next or previous page.
Returns the next page number. Raises InvalidPage if next page\ndoesn't exist.
Returns the previous page number. Raises InvalidPage if previous\npage doesn't exist.
Returns the 1-based index of the first object on the page, relative to all\nof the objects in the paginator's list. For example, when paginating a list\nof 5 objects with 2 objects per page, the second page's\nstart_index() would return 3.
Returns the 1-based index of the last object on the page, relative to all\nof the objects in the paginator's list. For example, when paginating a list\nof 5 objects with 2 objects per page, the second page's\nend_index() would return 4.
Daftar dari obyek-obyek pada halaman ini.
\nThe 1-based page number for this page.
\nObyek Paginator terkait.
A base class for exceptions raised when a paginator is passed an invalid\npage number.
\nThe Paginator.page() method raises an exception if the requested page is\ninvalid (i.e. not an integer) or contains no objects. Generally, it's enough\nto catch the InvalidPage exception, but if you'd like more granularity,\nyou can catch either of the following exceptions:
Raised when page() is given a value that isn't an integer.
Raised when page() is given a valid value but no objects\nexist on that page.
Both of the exceptions are subclasses of InvalidPage, so you can handle\nthem both with except InvalidPage.
