save
will run the validations before it persists, so there is no need to call valid?
if you are calling save
. The call to valid?
in the else
block is just to populate the errors on the object so your form can show them.

From what I remember Michael Hartl's Ruby on Rails Tutorial does a very good step by step guide to the following/followed via ajax part.
You are close! looking at the above the 'dataset' is empty which means your jquery targeting is slightly off.
I am assuming you want the value of modifier
for the location that is the selected .
$('select#location_id :selected').data('modifier');
if you look this in the console:
$('select#location_id :selected')
the dataset shouldn't be empty and you should see modifier
listed.
hope that helps.
I wish to add a billing_address and a delivery_address to my Client's.
So i thought i would make my Addresses polymorphic.
class Client < ActiveRecord::Base
has_many :addresses, as: :addressable
has_one :delivery_address, class_name: 'Address', as: :addressable
has_one :billing_address, class_name: 'Address', as: :addressable
def delivery_address
super || NullAddress.new
end
def billing_address
super || NullAddress.new
end
end
class Address < ActiveRecord::Base
belongs_to :addressable, polymorphic: true
def full_address
[line1, line2, town, county, postcode].compact.join(', ')
end
end
How ever when i try to update the billing address @client.billing_address
both the @client.billing_address
and @client.delivery_address
get set to the same address. And the previous addresses :addressable_id gets set to nil.
[1] #<Address:0x007f8bb1acdf20> {
:addressable_id => nil,
:addressable_type => "Client",
:country => "Ireland",
:county => "Limerick",
:created_at => Sat, 25 Jun 2016 17:43:48 UTC +00:00,
:id => 2,
:line1 => "123 New Street",
:line2 => "College Court",
:postcode => "DTW1234",
:town => "Limerick",
:updated_at => Sat, 25 Jun 2016 17:44:46 UTC +00:00
},
[2] #<Address:0x007f8bb1ace060> {
:addressable_id => 25,
:addressable_type => "Client",
:country => "Ireland",
:county => "Limerick",
:created_at => Sat, 25 Jun 2016 17:44:46 UTC +00:00,
:id => 3,
:line1 => "126 New Street",
:line2 => "College Court",
:postcode => "DTW1234",
:town => "Limerick",
:updated_at => Sat, 25 Jun 2016 17:58:14 UTC +00:00
}
]
Obviously I can still see all the addresses doing @client.addresses. But how do I implement and maintain reference to separate billing and delivery address for a client.
Any tips/pointers welcome,
Thanks :)
