1 How to use linaro-django-pagination
2 ----------------------------
4 ``linaro-django-pagination`` allows for easy Digg-style pagination without modifying
7 There are really 5 steps to setting it up with your projects (not including
8 installation, which is covered in INSTALL.txt in this same directory.)
10 1. List this application in the ``INSTALLED_APPS`` portion of your settings
11 file. Your settings file might look something like::
19 2. Install the pagination middleware. Your settings file might look something
22 MIDDLEWARE_CLASSES = (
24 'pagination.middleware.PaginationMiddleware',
27 3. If it's not already added in your setup, add the request context processor.
28 Note that context processors are set by default implicitly, so to set them
29 explicitly, you need to copy and paste this code into your under
30 the value TEMPLATE_CONTEXT_PROCESSORS::
32 ("django.core.context_processors.auth",
33 "django.core.context_processors.debug",
34 "django.core.context_processors.i18n",
35 "django.core.context_processors.media",
36 "django.core.context_processors.request")
38 4. Add this line at the top of your template to load the pagination tags:
40 {% load pagination_tags %}
43 5. Decide on a variable that you would like to paginate, and use the
44 autopaginate tag on that variable before iterating over it. This could
45 take one of two forms (using the canonical ``object_list`` as an example
48 {% autopaginate object_list %}
50 This assumes that you would like to have the default 20 results per page.
51 If you would like to specify your own amount of results per page, you can
54 {% autopaginate object_list 10 %}
56 Note that this replaces ``object_list`` with the list for the current page, so
57 you can iterate over the ``object_list`` like you normally would.
60 6. Now you want to display the current page and the available pages, so
61 somewhere after having used autopaginate, use the paginate inclusion tag:
65 This does not take any arguments, but does assume that you have already
66 called autopaginate, so make sure to do so first.
69 That's it! You have now paginated ``object_list`` and given users of the site
70 a way to navigate between the different pages--all without touching your views.
72 Custom pagination templates
73 ---------------------------
75 In order to override the default pagination template, declare a context variable
76 named ``pagination_template`` set to the template name::
78 {% with 'pagination/blog/post.html' as pagination_template %}
79 {% autopaginate posts pagesize %}
83 The default pagination template is contained in the ``pagination/default.html``
84 file inside the distribution.
89 It is important, when using linaro-django-pagination in conjunction with file uploads,
90 to be aware of when ``request.page`` is accessed. As soon as ``request.page``
91 is accessed, ``request.upload_handlers`` is frozen and cannot be altered in any
92 way. It's a good idea to access the ``page`` attribute on the request object
93 as late as possible in your views.
99 In linaro-django-pagination, there are no required settings. There are, however, a
100 small set of optional settings useful for changing the default behavior of the
101 pagination tags. Here's an overview:
103 ``PAGINATION_DEFAULT_PAGINATION``
104 The default amount of items to show on a page if no number is specified.
106 ``PAGINATION_DEFAULT_WINDOW``
107 The number of items to the left and to the right of the current page to
108 display (accounting for ellipses).
110 ``PAGINATION_DEFAULT_ORPHANS``
111 The number of orphans allowed. According to the Django documentation,
112 orphans are defined as::
114 The minimum number of items allowed on the last page, defaults to zero.
116 ``PAGINATION_INVALID_PAGE_RAISES_404``
117 Determines whether an invalid page raises an ``Http404`` or just sets the
118 ``invalid_page`` context variable. ``True`` does the former and ``False``
121 ``DISPLAY_PAGE_LINKS``
122 If set to ``False``, links for single pages will not be displayed.
124 ``PREVIOUS_LINK_DECORATOR``
125 An HTML prefix for the previous page link; the default value is ``‹‹ ``.
127 ``NEXT_LINK_DECORATOR``
128 An HTML postfix for the next page link; the default value is `` ››``.
130 ``DISPLAY_DISABLED_PREVIOUS_LINK``
131 If set to ``False``, the previous page link will not be displayed if there's
134 ``DISPLAY_DISABLED_NEXT_LINK``
135 If set to ``False``, the next page link will not be displayed if there's no
