Installation

pip install django-charsleft-widget

External dependencies

  • jQuery - this is not included in the package since it is expected that in most scenarios this would already be available.

Setup

Add charsleft_widget to INSTALLED_APPS:

INSTALLED_APPS += (
    'charsleft_widget',
)

and just include charsleft_widget templates

{% include "charsleft_widget/charsleft_widget_css.html" %} {# Before the closing head tag #}
{% include "charsleft_widget/charsleft_widget_js.html" %} {# Before the closing body tag #}

When deploying on production server, don’t forget to run:

python manage.py collectstatic

Usage

All you need now is to import ClearableInput class and override field’s widget, for example:

from django.forms.fields import CharField

from charsleft_widget import CharsLeftArea

class Form(forms.Form):

    field = CharField(max_length=128, widget=CharsLeftArea)

Please see example application. This application is used to manually test the functionalities of this package. This also serves as a good example.

You need only Django 1.4 or above to run that. It might run on older versions but that is not tested.
