validaciones en ruby

Question

He estado buscando en Google por un tiempo y sin tener suerte. Recibo un error "NoMethodError (método indefinido` with_indifferent_access ''"en mi servicio web cuando le paso atributos anidados.

Otros anidados funcionan, sin embargo son uno a uno y esto es uno a muchos ...

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

Trabajando correctamente:

    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}}}

Completed in 153ms (View: 4, DB: 1) | 201 Created [http://localhost/quotes.xml]

Sin embargo, al añadir

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

causa

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

Al eliminar el date_of_incident y solo se quejará del mismo atributo.

Anteriormente tuve "incident_attributes" (incidentes singulares) y has_many: incidente, pero cambiar esto no ayudó.

Answer 1

Debido a que el cliente tiene muchos incidentes, Rails espera que los "incidents_attributes" sean una matriz, no un hash. Esto debería suceder automáticamente, cuando lo haces:

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