6 How to use linaro-django-pagination
7 ===================================
9 ``linaro-django-pagination`` allows for easy Digg-style pagination without modifying
12 There are really 5 steps to setting it up with your projects (not including
13 installation, which is covered in :ref:`installation`.)
15 1. List this application in the ``INSTALLED_APPS`` portion of your settings
16 file. Your settings file might look something like::
20 'linaro_django_pagination',
24 2. Install the pagination middleware. Your settings file might look something
27 MIDDLEWARE_CLASSES = (
29 'linaro_django_pagination.middleware.PaginationMiddleware',
32 3. If it's not already added in your setup, add the request context processor.
33 Note that context processors are set by default implicitly, so to set them
34 explicitly, you need to copy and paste this code into your under
35 the value TEMPLATE_CONTEXT_PROCESSORS::
37 ("django.core.context_processors.auth",
38 "django.core.context_processors.debug",
39 "django.core.context_processors.i18n",
40 "django.core.context_processors.media",
41 "django.core.context_processors.request")
43 4. Add this line at the top of your template to load the pagination tags:
45 {% load pagination_tags %}
48 5. Decide on a variable that you would like to paginate, and use the
49 autopaginate tag on that variable before iterating over it. This could
50 take one of two forms (using the canonical ``object_list`` as an example
53 {% autopaginate object_list %}
55 This assumes that you would like to have the default 20 results per page.
56 If you would like to specify your own amount of results per page, you can
59 {% autopaginate object_list 10 %}
61 Note that this replaces ``object_list`` with the list for the current page, so
62 you can iterate over the ``object_list`` like you normally would.
65 6. Now you want to display the current page and the available pages, so
66 somewhere after having used autopaginate, use the paginate inclusion tag:
70 This does not take any arguments, but does assume that you have already
71 called autopaginate, so make sure to do so first.
74 That's it! You have now paginated ``object_list`` and given users of the site
75 a way to navigate between the different pages--all without touching your views.
77 Custom pagination templates
78 ===========================
80 In order to override the default pagination template use the extended form of
81 the ``paginate`` tag::
83 {% autopaginate posts pagesize %}
84 {% paginate using "pagination/blog/post.html" %}
86 The default pagination template is contained in the
87 ``pagination/pagination.html`` file inside the distribution.
92 It is important, when using linaro-django-pagination in conjunction with file
93 uploads, to be aware of when ``request.page`` is accessed. As soon as
94 ``request.page`` is accessed, ``request.upload_handlers`` is frozen and cannot
95 be altered in any way. It's a good idea to access the ``page`` attribute on
96 the request object as late as possible in your views.
102 In linaro-django-pagination, there are no required settings. There are,
103 however, a small set of optional settings useful for changing the default
104 behavior of the pagination tags. Here's an overview:
106 ``PAGINATION_DEFAULT_PAGINATION``
107 The default amount of items to show on a page if no number is specified.
110 ``PAGINATION_DEFAULT_WINDOW``
111 The number of items to the left and to the right of the current page to
112 display (accounting for ellipses). Defaults to 4.
114 ``PAGINATION_DEFAULT_MARGIN``
115 FIXME: This needs to be documented.
117 ``PAGINATION_DEFAULT_ORPHANS``
118 The number of orphans allowed. According to the Django documentation,
119 orphans are defined as::
121 The minimum number of items allowed on the last page, defaults to zero.
123 ``PAGINATION_INVALID_PAGE_RAISES_404``
124 Determines whether an invalid page raises an ``Http404`` or just sets the
125 ``invalid_page`` context variable. ``True`` does the former and ``False``
126 does the latter. Defaults to False
128 ``PAGINATION_DISPLAY_PAGE_LINKS``
129 If set to ``False``, links for single pages will not be displayed. Defaults to True.
131 ``PAGINATION_PREVIOUS_LINK_DECORATOR``
132 An HTML prefix for the previous page link; the default value is ``‹‹``.
134 ``PAGINATION_NEXT_LINK_DECORATOR``
135 An HTML postfix for the next page link; the default value is ``››``.
137 ``PAGINATION_DISPLAY_DISABLED_PREVIOUS_LINK``
138 If set to ``False``, the previous page link will not be displayed if there's
139 no previous page. Defaults to False.
141 ``PAGINATION_DISPLAY_DISABLED_NEXT_LINK``
142 If set to ``False``, the next page link will not be displayed if there's no
143 next page. Defaults to False.
