This allows for easy generation of HTML5 placeholders based on a form_field's label. Use like so:
{% form_placeholder form.username %}
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | from django import template
from django.forms import Field
register = template.Library()
class PlaceholderForm(template.Node):
def __init__(self, form_field):
self.form_field = form_field
def render(self, context):
html = self.form_field.resolve(context)
label = html.label
return html.as_widget(attrs={'placeholder':label})
@register.tag
def form_placeholder(parser, token):
try:
tag_name, form_field_string = token.split_contents()
except ValueError:
raise template.TemplateSyntaxError('{0} tag requires a single argument'.format( token.contents.split()[0]))
form_field = parser.compile_filter(form_field_string)
return PlaceholderForm(form_field)
