"NoMethodError (undefined method `with_indifferent_access' for..." when passing it nested attributes

开发者_JAVA技巧Been googling this for a while and having no luck. I'm getting an "NoMethodError (undefined method `with_indifferent_access'" error on my web service when passing it nested attributes.

Other nested ones work, they are one-to-one however and this is one-to-many...

class Customer < ActiveRecord::Base

  belongs_to :quote

  has_one :policy, :dependent => :destroy
  has_one :vehicle, :dependent => :destroy
  has_many :claims, :dependent => :destroy
  has_many :incidents, :dependent => :destroy

  accepts_nested_attributes_for :policy
  accepts_nested_attributes_for :vehicle
  accepts_nested_attributes_for :incidents
end

Working correctly:

    Processing QuotesController#create to xml (for 127.0.0.1 at 2010-12-12 15:16:33) [POST]
  Parameters: {"quote"=>{"customer_attributes"=>{"address1"=>nil, "city"=>"ggh", "dob"=>nil, "address2"=>nil, "title"=>nil, "country"=>nil, "postcode"=>nil, "vehicle_attributes"=>{"mileage"=>nil, "registration"=>nil, "value"=>nil, "parking"=>nil}, "policy_attributes"=>{"breakdown"=>nil, "windscreen"=>"1", "excess"=>nil}, "telephone"=>nil, "surname"=>nil, "forename"=>"wasdddfggh", "email"=>nil}}}
  [4;35;1mQuote Create (1.0ms)[0m   [0mINSERT INTO "quotes" ("created_at", "updated_at") VALUES('2010-12-12 15:16:33', '2010-12-12 15:16:33')[0m

  [4;35;1mPolicy Create (0.0ms)[0m   [0mINSERT INTO "policies" ("breakdown", "created_at", "windscreen", "excess", "updated_at", "customer_id") VALUES(NULL, '2010-12-12 15:16:33', 1, NULL, '2010-12-12 15:16:33', 2)[0m
  [4;36;1mVehicle Create (0.0ms)[0m   [0;1mINSERT INTO "vehicles" ("mileage", "created_at", "updated_at", "registration", "value", "parking", "customer_id") VALUES(NULL, '2010-12-12 15:16:33', '2010-12-12 15:16:33', NULL, NULL, NULL, 2)[0m
Completed in 153ms (View: 4, DB: 1) | 201 Created [http://localhost/quotes.xml]
host/quotes.xml]

However, when adding

"incidents_attributes"=>{"date_of_incident"=>"2008-05-19", "sum_of_claim"=>"34554", "description"=>"PLEASE!"},

it causes

NoMethodError (undefined method `with_indifferent_access' for "2008-05-19":String):

Removing the date_of_incident and it will just complain the same about the next attribute.

Previously I had "incident_attributes" (singular incident) and has_many :incident, but changing this didn't help.


because customer has many incidents, Rails expects the "incidents_attributes" to be an array, not a hash. This should automatically happen, when you do:

<%= form_for @customer do |f| %>
  <%= f.fields_for :incidents do |incident_fields| %>
    <%= incident_fields.date_select :date_of_incident %>
  <% end %>
<% end %>
