Hi!
I have a problem with the presentation of error messages for multiple
objects. The validation works fine and if errors occure they will all
be presented, but only for one object at a time. When I submit my form
the occuring errors will be presented and if I fix them and submit the
form again the errors for the next form will be presented and so on.
I don't know what I have to do to show all errors for all objects at
once.
In my view template I use <%= error_messages_for payment,
subscription, user %>.
This is how my create method looks like:
def create
@payment = Payment.new(params[:payment])
@subscription = Subscription.new(params[:subscription])
@user = User.new(params[:user])
@service = SubscriptionService.new(@subscription, @user, @payment)
if @service.save
flash[:notice] = 'Subscription was successfully created.'
redirect_to root_url
else
render :action => "new"
end
end
This is how my SubscriptionService looks like:
class SubscriptionService
attr_reader :payment, :subscription, :user
def initialize(subscription, user, payment)
@payment = payment
@user = user
@subscription = subscription
end
def save
return false unless valid?
begin
Subscription.transaction do
if @payment.new_record?
@payment.subscription = @subscription
@payment.save!
end
if @user.new_record?
@user.subscription = @subscription
@user.save!
end
@subscription.save!
true
end
rescue
false
end
end
def valid?
@payment.valid? && @subscription.valid? && @user.valid?
end
end
I think this is pretty basic code and I already found out that the
presentation has something to do with valid? method in the
SubscriptionService but as I said I don't know how and where to
collect all error messages and present them at once.
Many thanks in advance.
Regards,
Stefan
