Countable Field is a simple Django custom for widget for displaying a text area with the current word count displayed underneath. It can be set up to display the count in red when the current word count is out of required minimum or maximum word count for the form field.
Add "countable_field" to your INSTALLED_APPS setting like this:
INSTALLED_APPS = [ ... 'countable_field', ]
2. In the form, set the field's widget to be "CountableWidget", passing the minimum and maximum word count as additional parameters, such as:
self.fields['essay_response'].widget = \ CountableWidget(attrs={'data-min-count': this.essay_min_length, 'data-max-count': this.essay_max_length})
