我已经看到了一些与此类似的问题，但与在 Rails 中使用 Cocoon gem 和 Wicked multi step form Gem 无关。当我有一个 has_many 关联时，表单保存得很好，但是当有一个 has_one 关联（客户端 has_one 医生）时，记录似乎保存然后删除。花了很长时间试图弄清楚这一点，但就是不明白为什么会这样。
class QuotesController < ApplicationController
include Wicked::Wizard
before_action :set_client, only: [:show, :update, :quote_success]
steps :profile, :employment, :general_questions, :indemnity_details, :declarations
def show
@client.build_doctor
@client.old_insurers.build
@client.practice_addresses.build
render_wizard
end
def update
@client.update(client_params)
render_wizard @client
end
def quote_success; end
private
def set_client
current_user = Client.find_by_id(session[:current_user_id])
@client = current_user
end
def finish_wizard_path
if @client.valid?
ClientMailer.new_quote(@client).deliver
ClientMailer.new_quote_user_message(@client).deliver
end
quote_success_path
end
end
def client_params
params.require(:client).permit(:name, :email, :email_confirmation, :phone, :date_required,
:title, :first_name, :last_name, :date_of_birth, :nationality, :reg_body,
practice_addresses_attributes: [:id, :pa_line1, :pa_line2, :pa_line3, :pa_town, :pa_county, :pa_postcode, :other_practices, :_destroy],
old_insurers_attributes: [:id, :insurer, :oi_to, :oi_from, :oi_limit, :oi_excess, :oi_premium, :_destroy],
doctor_attributes: [:id, :gp_locum, :gp_locum_sessions, :gp_locum_locations])
end
end
客户型号：
class Client < ActiveRecord::Base
has_one :doctor, dependent: :destroy
has_many :practice_addresses, dependent: :destroy
has_many :callbks, inverse_of: :client
has_many :old_insurers, dependent: :destroy
accepts_nested_attributes_for :doctor
accepts_nested_attributes_for :old_insurers, reject_if: :all_blank, allow_destroy: true
accepts_nested_attributes_for :callbks
accepts_nested_attributes_for :practice_addresses, reject_if: :all_blank, allow_destroy: true
end
医生型号：
class Doctor < ActiveRecord::Base
belongs_to :client
end
查看有问题的部分：
<%= simple_form_for @client, url: wizard_path do |f| %>
<%= yield f %>
....
<div id="doctors">
<%= f.simple_fields_for :doctor do |gp| %>
<%= render 'doctor_fields', f: gp %>
<% end %>
</div>
医生字段：
<div class="nested-fields">
<div class="panel panel-default">
<div class="panel-heading">
<strong>General Questions - GP</strong>
</div>
<div class="panel-body">
<div class="table-responsive">

<table class="table table-striped">
