Set use_locale=True on DecimalField #1698

Open SBillion opened 6 years ago

SBillion commented 6 years ago

I would like to set use_locale on a DecimalField in form_extra_fields. Unfortunately, I got the following error:

ERROR:flask.app:Exception on /admin/product/edit/ [GET]

Problem still exists. pip list Package Version

TypeError: 'bool' object is not subscriptable

inputfield1 = DecimalField(label='Take Profit1 Price', rounding=None, use_locale=True)

Workaround: remove use_locale=True. But I like to use locale. Please give advice. Thanks
