maxlength 4 for integer attributes error

[IrinaBron]

Hi,

I'm running into this closed issue again when I try to cast an int as another type. (#728). This seems to have coincided with upgrading Rails to 5.2.4.4.

ex: f.input :value, as: :string

To bypass this, I've been manually adding input_html: { maxlength: "" } to each input as a temporary fix.

Specs:
Rails 5.2.4.4
Ruby 2.5.8p224
ActiveAdmin 1.4.3
Formtastic 3.1.5

Any help highly appreciated! Thank you 😄
