More HTML5 goodness, please!

Seeing as Chrome 6 now joins Safari in adding custom UI on top of <input type="number"/> elements, it would be awesome if it was easier to add the new attributes to the element.

In particular, min, max, and step would improve the experience, also on mobile devices.

Could these be inferred by the presence of a NumericalityValidator? Otherwise, allowing these options directly in the input call would be preferred over having to use :input_html.

I love simple_form!

I believe min and max could be inferred by the NumericalityValidator, but to use step you'd still have to use :input_html.
Could you work on a patch and send us a pull request? Thanks.

I've read through NumericalityValidator, and there's no public API exposed that could be used. Is it okay if I cheat and use the private internals of the class? What's your policy on that?

[carlosantoniodasilva]

You can use the public API:

User.validators_on(:age) # will give you an array with all validators in this attribute

You can detect if there is an NumericalityValidator and get its options to create the needed html attributes.
