私のRubyアプリケーションでRubyに問題があります。私は2つのモデルを持っています - 「患者」と「住所」、患者は1つの住所を持ち、住所は患者に属します。Ruby on RailsアプリケーションでAssociationTypeMismatchエラーが発生しました
Patient.rb
class Patient < ActiveRecord::Base
has_many :charge_slips
has_one :address
validates_presence_of :last_name
validates_presence_of :first_name
validates_presence_of :middle_name
end
Address.rb
class Address < ActiveRecord::Base
belongs_to :patient
validates_associated :patient
end
患者controller.rb
class PatientController < ApplicationController
def index
@title = "Outpatient Services - Patient"
@today = Date.today.to_formatted_s(:long)
@patients = Patient.find(:all)
end
def new
@patient = Patient.new
@address = Address.new
end
def create
@patient = Patient.new(params[:patient])
@patient.created_on = Date.today.to_formatted_s(:long)
if @patient.save
@address = Address.new(params[:address])
@address.patient_id = @patient.id
if @address.save
redirect_to :action => 'index'
else
redirect_to :action => 'new'
end
redirect_to :action => 'index'
else
redirect_to :action => 'new'
end
end
end
new.html.rb
<%= content_tag('h3', 'Create New Patient') %>
<hr>
<% form_for @patient, :url => { :action => "create" } do |patient_form| -%>
<%= error_messages_for :patient %>
<%= patient_form.label :last_name, 'Last Name:' %> <%= patient_form.text_field :last_name, :size => 30 %><br>
<%= patient_form.label :first_name, 'First Name:' %> <%= patient_form.text_field :first_name, :size => 30 %><br>
<%= patient_form.label :middle_name, 'Middle Name:' %> <%= patient_form.text_field :middle_name, :size => 30 %><br>
<fieldset>
<legend>Patient's Permanent Address</legend>
<%= error_messages_for :address %>
<% patient_form.fields_for @address do |address_fields| -%>
<%= address_fields.label :street_name, 'Street Name:' %> <%= address_fields.text_field :street_name %><br>
<%= address_fields.label :barangay, 'Barangay:' %> <%= address_fields.text_field :barangay %><br>
<%= address_fields.label :city_municipality, 'City/Municipality:' %> <%= address_fields.text_field :city_municipality %><br>
<%= address_fields.label :country, 'Country:' %> <%= address_fields.text_field :country %><br>
<%= address_fields.label :zip_cide, 'Zip Code:' %> <%= address_fields.text_field :zip_code %><br>
<% end -%>
</fieldset>
<%= submit_tag "Add Patient" %>
<% end -%>
新しい患者を追加するたびに、エラーがスローされます。以下はエラーの一部です:

私はRoRを初めて使い、練習を通してその言語を習得したいと考えています。私はコードに何が間違っているのかを知りたい。ありがとう!
