Rails number_field alternative for decimal values

Question

I\'m trying to accept a decimal value (USD, so 12.24 would be an example) with the number_field method.

  <%= f.number_fiel         


        
      

Answer 1

For price fields you can use this:

f.number_field :price, value: @item.price ? '%.2f' % @item.price : nil, min: 0, step: 0.01

It works fine even if you allow blank values.
