Handling errors with Braintree - Ruby -

i using braintree process payments via web application, no problems far, plenty of documentation little unsure of how handle errors in controller. don't think should looking display error messages user pose security risk handle errors better now, perhaps capturing selection of generic errors?

the point of question here how go capturing these, within rescue or create method errors go through , display custom messages errors?

at moment have simple controller action

@result = braintree::transaction.sale(             amount: @amount,             payment_method_nonce: params[:payment_method_nonce],             options: {               submit_for_settlement: true             }           ) if @result.success?   redirect_to thank_you_path else   flash[:alert] = 'something went wrong while processing transaction. please try again!'   gon.client_token = generate_client_token   render :new end 

i display generic "something went wrong" message when @result not successful.

i'm sure there better ways deal , appreciated suggestions

thnaks

the result instance of object, having whole information transaction status.

you might extract whatever information want , print out client.

e.g. group messages error code, 1 might use smth this:

unless @result.success?   flash[:alert] = case @result.transaction.processor_response_code.to_s                   when /^2/ "contact bank"                   else "something went wrong"                   end   ... end
