django - Change form input attribute 'name' to 'data-encrypted-name' -

this tricky question title, please read before assuming duplicate :).

i'm using braintree payments on django site, , payment form html needs credit card number:

<input type="text" size="20" autocomplete="off" data-encrypted-name="number" /> 

mine looks this:

<input type="text" size="20" autocomplete="off" name="number"> 

can somehow rename name data-encrypted-name? alternatively, can hide/remove name attribute altogether? if so, add custom attribute braintree-friendly attribute:

class signupform(forms.form):     ...snip...      def __init__(self, *args, **kwargs):          super(signupform, self).__init__(*args, **kwargs)           self.fields['number'].widget.attrs['data-encrypted-name'] = "number" 

fyi tried in __init__ no luck:

         self.fields['number'].widget.attrs['name'] = none 

per braintree:

important: not use name attribute fields capture sensitive payment information such credit card number or cvv. removing attribute prevents them hitting server in plain text , reduces pci compliance scope.

also, i'm using django crispy forms, i'd prefer solve in forms.py , not in template html tweaks in order keep dry.

define custom widget class inheriting whatever widget type numbers field defaults (textinput, judging tag you're showing) , override build_attrs method.

i'd this:

class sensitivetextinput(textinput):     def build_attrs(self, extra_attrs=none, **kwargs):         attrs = super(sensitivetextinput, self).build_attrs(extra_attrs, **kwargs)         if 'name' in attrs:             attrs['data-encrypted-name'] = attrs['name']             del attrs['name']         return attrs 

if need more handful of widget types abstract mixin.
