Not able to implement multiple pagination using Django Endless Pagination

Question

I am using Twitter Style Pagination to load my feed while scrolling down. Everything works fine.

Problem is with multiple paginations on the same template. I have written my code as explained here.

But I am getting this weird error:

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

{% paginate activity_obj using activity %}

and the error shows as:

VariableDoesNotExist at /accounts/home/

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;

Not able to understand what this error message is about. Please help.

Answer 1

The error is stating that the variable activity does not exist in the context. You either need to add it to your context in the view, or you don't need a variable at all. You can just pass a string like this: {% paginate activity_obj using "activity" %}. So it depends on what you are trying to do. If your query string parameter name is actually the string "activity", then just surround activity with quotes. If you are dynamically setting the variable in the view code, then you need to put it in the context so you can access it in the template.
