display braintree errors on fail - ruby-on-rails

Question

hi i am trying to get my braintree account to display errors when creating a transaction but it doesn't appear to be working
- flash.each do |key, value|
%div{:class => "alert alert-#{key}"}= value
def update
result = Braintree::Transaction.sale(
:amount => params[:amount_to_add].to_f,
# :order_id => "order id",
:customer_id => customer.customer_cim_id,
:tax_amount => (params[:amount_to_add].to_f / 11).round(2),
:options => {
:submit_for_settlement => true
}
)
if result.success?
logger.info "Added to #{params[:amount_to_add].to_f} to #{customer.first_name} #{customer.last_name} (#{customer.customer_cim_id})"
customer.store_credit.add_credit(params[:amount_to_add].to_f)
redirect_to myaccount_store_credit_path
# , :notice => "Successfully updated store credit."
else
result.errors.each do |error|
puts error.message
customer.errors.add(:base, error.message)
render :show, :notice => error.message
end
end
end

I believe the reason you're probably unable to see the errors is because of the :notice option on your render method, which is redundant because render doesn't seem to be using the :notice option, only redirect_to. You may just add the errors to your to your flash, but note that in your view you have to loop through the errors within the flash to render it.
Another way I would think you do this though is add the payment method to your User model
class User|Customer
...
def process_braintree_payment(amount)
result = Braintree::Transaction.sale(
:amount => amount.to_f,
# :order_id => "order id",
:customer_id => customer_cim_id,
:tax_amount => (amount.to_f / 11).round(2),
:options => {
:submit_for_settlement => true
}
)
add_braintree_errors(result.error) unless result.success?
end
def add_braintree_errors(error_object)
error_object.each do |error|
errors.add(:braintree, error.message)
end
end
end
class XController
def update
#customer.process_braintree_payment(params[:amount_to_add])
if #customer.errors.empty?
logger.info "Added to #{params[:amount_to_add].to_f} to #{#customer.first_name} #{#customer.last_name} (#{#customer.customer_cim_id})"
#customer.store_credit.add_credit(params[:amount_to_add].to_f)
redirect_to myaccount_store_credit_path
# , :notice => "Successfully updated store credit."
else
render :show
end
end
end
In your view, you have access to the #customer variable or better you could store the error object in the ActionController#flash, note however, using the same keys for your flash messages, would overwrite the previous value.
