How can I allow Stripe to accept whole and decimal values on rails?

Question

Implemented Stripe on aa rails project. Stripe takes amount of '500' and sends 5.00 to their API by default. If I do amount.to_i*100 I can get '500' to stay 500, but then when amount = 5.67 getting 5.00 still.

How can I change the controller, view or field to allow for both correctly?

CONTROLLER CODE

@amount = params[:amount].to_i*100

VIEW CODE

<input class="form-field two-decimals" name="amount" type="number" step="any" >

Answer 1

您可以这样做：

@amount = sprintf("%.2f",(params[:amount])).delete '.'

Answer 2

Stripe takes only integer, to get proper integer you can multiply amount to 100.

(@amount * 100).to_i => 44.53 * 100 = 4453.0.to_i and converting to integer 4453

def charge
    begin
        charged = Stripe::Charge.create(
          :amount   => (@amount * 100).to_i,
          :currency => "usd",
          :customer => @customer_id
        )
    rescue Stripe::InvalidRequestError, Stripe::AuthenticationError, Stripe::APIConnectionError, Stripe::StripeError => e
        puts e.message
        return false
    end
    charged
end
