I wasn't able to find a way to identify the type of a field in a django template. My solution was to create a simple filter to access the field and widget class names. I've included the code below in case it's helpful for someone else.
Is there a better approach?
## agency/tagutils/templatetags/fieldtags.py
###############################################################
from django import template
register = template.Library()
@register.filter(name='field_type')
def field_type(value):
return value.field.__class__.__name__
@register.filter(name='widget_type')
def widget_type(value):
return value.field.widget.__class__.__name__
## client/project/settings.py
###############################################################
INSTALLED_APPS = (
# ...
'agency.tagutils',
)
## client/project/templates/project/field_snippet.html
###############################################################
{% load fieldtags %}
<div class="field {{ field|field_type }} {{ field|widget_type }} {{ field.name }}">
{{ field.errors }}
<div class="form_label">
{{ field.label_tag }}
</div>
<div class="form_field">
{{ field }}
</div>
</div>
## sample output html
###############################################################
<div class="field CharField TextInput family_name">
<div class="form_label">
<label for="id_family_name">Family name</label>
</div>
<div class="form_field">
<input id="id_family_name" type="text" name="family_name" maxlength="64" />
</div>
</div>
