Useful templatetags for Django projects.

Installation

Install from PyPi:

pip install wt-django-templatetags

Install from GitHub:

To install the development branch from GitHub:

pip install "wt-django-templatetags @ git+https://github.com/ian-wt/wt-django-templatetags.git"

Once installed, add wt_templatetags to INSTALLED_APPS in your settings module.

INSTALLED_APPS = [
    # other packages
    'wt_templatetags',
]

Alternatively, you could register a particular module of templatetags directly in your TEMPLATES setting.

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                ...
            ],
            'libraries': {
                'pagination_tags': 'wt_templatetags.templatetags.pagination_tags',
            }
        },
    },
]

This is most useful when you're only interested in using a limited set of modules from the broader project and that's unlikely to change. For simplicity, I recommend using the INSTALLED_APPS approach rather than selectively registering modules.

Use

Pagination Tags

To use the pagination_tags templatetags library in your project, first load the tags with {% load pagination_tags %}.

To use the relative_url tag, you need to pass to the tag a page index. This could be a number or the string 'last' if the index is in the final position of the paginated QuerySet. The tag additionally accepts optional arguments for field_name and urlencode.

Most often, you'll leave the field_name parameter alone since the default value of 'page' is fairly semantic as it is. However, this value can be overridden in your views so make sure your views and the field_name are consistent.

Last, the urlencode parameter is used when a query string may be present. If your view won't ever handle a query string, then you can leave the default value of None alone.

Example

{% extends 'base.html' %}
{% load pagination_tags %}
<h1>Hello World!</h1>
<a href="{% relative_url page_obj.next_page_number %}">Next Page</a>

To extend this example further we can supply values to override the defaults:

{% extends 'base.html' %}
{% load pagination_tags %}
<h1>Hello World!</h1>
<a href="{% relative_url page_obj.next_page_number 'page' request.GET.urlencode %}">Next Page</a>
