Not able to validate credit card using active merchant? - ruby-on-rails

Question

When i charge credit card using form, it throws validation error "The credit card information you provided is not valid. Please double check the information you provided and then try again."
Any solution??
This is my payment.rb
class Payment < ActiveRecord::Base
require "active_merchant/billing/rails"
attr_accessor :card_security_code
attr_accessor :credit_card_number
attr_accessor :expiration_month
attr_accessor :expiration_year
validates :first_name, presence: true
validates :last_name, presence: true
validates :card_security_code, presence: true
validates :credit_card_number, presence: true
validates :expiration_month, presence: true, numericality: { greater_than_or_equal_to: 1, less_than_or_equal_to: 12 }
validates :expiration_year, presence: true
validates :amount, presence: true, numericality: { greater_than: 0 }
validate :valid_card
def credit_card
ActiveMerchant::Billing::CreditCard.new(
number: credit_card_number,
verification_value: card_security_code,
month: expiration_month,
year: expiration_year,
first_name: first_name,
last_name: last_name
)
end
def valid_card
if !credit_card.valid?
errors.add(:base, "The credit card information you provided is not valid. Please double check the information you provided and then try again.")
false
else
true
end
end
def process
if valid_card
response = GATEWAY.authorize(amount * 100, credit_card)
if response.success?
transaction = GATEWAY.capture(amount * 100, response.authorization)
if !transaction.success?
errors.add(:base, "The credit card you provided was declined. Please double check your information and try again.") and return
false
end
update_columns({authorization_code: transaction.authorization, success: true})
true
else
errors.add(:base, "The credit card you provided was declined. Please double check your information and try again.") and return
false
end
end
end
end
This is my activemerchant.rb
if Rails.env == 'development'
ActiveMerchant::Billing::FirstdataE4Gateway.wiredump_device = File.open(Rails.root.join('log','active_merchant.log'), 'a+')
ActiveMerchant::Billing::FirstdataE4Gateway.wiredump_device.sync = true
ActiveMerchant::Billing::Base.mode = :test
login = 'mylogin'
password='mypassword'
elsif Rails.env == 'production'
login = 'mylogin'
password='mypassword'
end
GATEWAY = ActiveMerchant::Billing::FirstdataE4Gateway.new({
login: login,
password: password
})

You also need to provide credit card brand name as
def credit_card
ActiveMerchant::Billing::CreditCard.new(
number: credit_card_number, # 4111111111111111
verification_value: card_security_code, # 123
month: expiration_month, # 1
year: expiration_year, # 2020
first_name: first_name, # Bibek
last_name: last_name, # Sharma
brand: credit_card_brand # visa
)
end
