无法使用Django Endless Pagination实现多重分页

Question

我正在使用Twitter Style Pagination加载我的Feed，同时向下滚动。一切正常。

问题在于同一模板上的多个分页。我按照here的解释编写了我的代码。

但我得到了这个奇怪的错误：

Error during template rendering at line in other_entries_page.html::

{% paginate activity_obj using activity %}

，错误显示为：

/ accounts / home /

中的VariableDoesNotExist

Failed lookup for key [activity] in u'[{\'False\': False, \'None\': None, \'True\': True}, {u\'csrf_token\': <django.utils.functional.__proxy__ object at 0x7fa56404b5d0>}, {\'perms\': <django.contrib.auth.context_processors.PermWrapper object at 0x7fa56404bf10>, \'user\': <django.utils.functional.SimpleLazyObject object at 0x7fa564034710>}, {}, {u\'LANGUAGES\': ((\'af\', \'Afrikaans\'), (\'ar\', \'Arabic\'), (\'az\', \'Azerbaijani\'), (\'bg\', \'Bulgarian\'), (\'be\', \'Belarusian\'), (\'bn\', \'Bengali\'), (\'br\', \'Breton\'), (\'bs\', \'Bosnian\'), (\'ca\', \'Catalan\'), (\'cs\', \'Czech\'), (\'cy\', \'Welsh\'), (\'da\', \'Danish\'), (\'de\', \'German\'), (\'el\', \'Greek\'), (\'en\', \'English\'), (\'en-gb\', \'British English\'), (\'eo\', \'Esperanto\'), (\'es\', \'Spanish\'), (\'es-ar\', \'Argentinian Spanish\'), (\'es-mx\', \'Mexican Spanish\'), (\'es-ni\', \'Nicaraguan Spanish\'), (\'es-ve\', \'Venezuelan Spanish\'), (\'et\', \'Estonian\'), (\'eu\', \'Basque\'), (\'fa\', \'Persian\'), (\'fi\', \'Finnish\'), (\'fr\', \'French\'), (\'fy-nl\', \'Frisian\'), (\'ga\', \'Irish\'), (\'gl\', \'Galician\'), (\'he\', \'Hebrew\'), (\'hi\', \'Hindi\'), (\'hr\', \'Croatian\'), (\'hu\', \'Hungarian\'), (\'ia\', \'Interlingua\'), (\'id\', \'Indonesian\'), (\'is\', \'Icelandic\'), (\'it\', \'Italian\'), (\'ja\', \'Japanese\'), (\'ka\', \'Georgian\'), (\'kk\', \'Kazakh\'), (\'km\', \'Khmer\'), (\'kn\', \'Kannada\'), (\'ko\', \'Korean\'), (\'lb\', \'Luxembourgish\'), (\'lt\', \'Lithuanian\'), (\'lv\', \'Latvian\'), (\'mk\', \'Macedonian\'), (\'ml\', \'Malayalam\'), (\'mn\', \'Mongolian\'), (\'nb\', \'Norwegian Bokmal\'), (\'ne\', \'Nepali\'), (\'nl\', \'Dutch\'), (\'nn\', \'Norwegian Nynorsk\'), (\'pa\', \'Punjabi\'), (\'pl\', \'Polish\'), (\'pt\', \'Portuguese\'), (\'pt-br\', \'Brazilian Portuguese\'), (\'ro\', \'Romanian\'), (\'ru\', \'Russian\'), (\'sk\', \'Slovak\'), (\'sl\', \'Slovenian\'), (\'sq\', \'Albanian\'), (\'sr\', \'Serbian\'), (\'sr-latn\', \'Serbian Latin\'), (\'sv\', \'Swedish\'), (\'sw\', \'Swahili\'), (\'ta\', \'Tamil\'), (\'te\', \'Telugu\'), (\'th\', \'Thai\'), (\'tr\', \'Turkish\'), (\'tt\', \'Tatar\'), (\'udm\', \'Udmurt\'), (\'uk\', \'Ukrainian\'), (\'ur\', \'Urdu\'), (\'vi\', \'Vietnamese\'), (\'zh-cn\', \'Simplified Chinese\'), (\'zh-tw\', \'Traditional Chinese\')), u\'LANGUAGE_BIDI\': False, u\'LANGUAGE_CODE\': \'en-us\'}, {u\'MEDIA_URL\': \'/media/\'}, {u\'STATIC_URL\': \'/static/\'}, {u\'TIME_ZONE\': \'Asia/Kolkata\'}, {u\'request\': <WSGIRequest\npath:/accounts/home/,\nGET:<QueryDict: {}>,\nPOST:<QueryDict: {}>,\nCOOKIES:{\'csrftoken\': \'EqzLQqDxLReLeY9748OIFavZYGIyEKu6\',\n \'sessionid\': \'7ghle3l0naigipqq5kvwbr6tbmw65ul7\'},\nMETA:{\'COLORTERM\': \'gnome-terminal\',\n \'COMPIZ_CONFIG_PROFILE\': \'ubuntu\',\n \'CONTENT_LENGTH\': \'\',\n \'CONTENT_TYPE\': \'text/plain\',\n u\'CSRF_COOKIE\': u\'EqzLQqDxLReLeY9748OIFavZYGIyEKu6\',\n u\'CSRF_COOKIE_USED\': True,\n \'DBUS_SESSION_BUS_ADDRESS\': \'unix:abstract=/tmp/dbus-VdpkiAyrl4,guid=2d795369fb38e64bfe3402be00000019\',\n \'DEFAULTS_PATH\': \'/usr/share/gconf/ubuntu.default.path\',\n \'DESKTOP_SESSION\': \'ubuntu\',\n \'DISPLAY\': \':0\',\n \'DJANGO_SETTINGS_MODULE\': \'doroko.settings\',\n \'GATEWAY_INTERFACE\': \'CGI/1.1\',\n \'GDMSESSION\': \'ubuntu\',\n \'GNOME_DESKTOP_SESSION_ID\': \'this-is-deprecated\',\n \'GNOME_KEYRING_CONTROL\': \'/tmp/keyring-FV73UN\',\n \'GPG_AGENT_INFO\': \'/tmp/keyring-FV73UN/gpg:0:1\',\n \'HOME\': \'/home/deep\',\n \'HTTP_ACCEPT\': \'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\',\n \'HTTP_ACCEPT_ENCODING\': \'gzip, deflate\',\n \'HTTP_ACCEPT_LANGUAGE\': \'en-US,en;q=0.5\',\n \'HTTP_CACHE_CONTROL\': \'max-age=0\',\n \'HTTP_CONNECTION\': \'keep-alive\',\n \'HTTP_COOKIE\': \'csrftoken=EqzLQqDxLReLeY9748OIFavZYGIyEKu6;

无法理解此错误消息的内容。请帮忙。

Answer 1

错误表明变量activity在上下文中不存在。您需要将其添加到视图中的上下文中，或者根本不需要变量。你可以像这样传递一个字符串：{% paginate activity_obj using "activity" %}。所以这取决于你想要做什么。如果您的查询字符串参数名称实际上是字符串"activity"，那么只需用引号括起activity。如果要在视图代码中动态设置变量，则需要将其放在上下文中，以便可以在模板中访问它。
