インストール完了です。
settings.pyを変更します。
次は設定変更です。
#vi urls.py
INSTALLED_APPS = (
'pagination',
)
MIDDLEWARE_CLASSES = (
'pagination.middleware.PaginationMiddleware',
)
TEMPLATE_CONTEXT_PROCESSORS = (
'django.core.context_processors.i18n',
'django.core.context_processors.request',
)
PAGINATION_DEFAULT_PAGINATION = 2
テンプレートを編集します。
#vi ./templates/hoge.html
{% load pagination_tags %}
{% autopaginate list 20 %}
{% for item in list %}
{% endfor %}
{% paginate %}これで利用できるようになります。
例外：テンプレートエラー
TemplateSyntaxError at /hoge/ Caught KeyError while rendering: 'request'
のようなエラーが出る場合は、settings.pyの
TEMPLATE_CONTEXT_PROCESSORSを確認してください。
おまけ
TEMPLATE_CONTEXT_PROCESSORSが上書きされて、エラーが出る場合は、
次のように設定しなおしてみてください。
from django.conf import global_settings
TEMPLATE_CONTEXT_PROCESSORS = global_settings.TEMPLATE_CONTEXT_PROCESSORS + (
'django.core.context_processors.i18n',
'django.core.context_processors.request',
) これでページ送りが使えるようになります。便利です。
