Rails嵌套的属性rails update_not_found更新时

Question

I have 2 models like:

class Customer < ActiveRecord::Base
 has_many :passengers
 accepts_nested_attributes_for :passengers, allow_destroy: true
end

class Passenger < ActiveRecord::Base
 belongs_to :customer
end

customer_params contain :

:name,...
:passengers_attributes: [:id, :name, :_destroy]

and when pass passengers_attributes to update customer (id=1) like

{
  "passengers_attributes": [
    {
      "name": "abc",
      "id": 5
    }
  ]
}

With passenger "abc" is new record

When i run customer.update_attributes!(customer_params) , it raise error ActiveRecord::RecordNotFound: Couldn't find Passenger with ID=5 for Customer with ID=1

Do you know this error? i need your help. Thanks

Found your error here

{
  "passengers_attributes": [
    {
      "name": "abc",
      "id": 5
    }
  ]
}

You can't send id in parameters here. Id can't be modified or you can insert it manually.

Here your customer don't have passenger with id "5".that's why you are getting this error.
