Cocoon has_one関連Wicked Gem - Railsを使用してセーブ/アップデートを中断する

Question

これに似た質問がありましたが、WickedマルチステップフォームGem in in RailsでCocoon gemを使用することについては何も見ていません。 has_manyアソシエーションがある場合でもフォームは正常に保存されますが、has_oneアソシエーション（Client has_one doctor）がある場合、レコードは保存されてから削除されるようです。これを理解しようとずっと長い時間を費やしましたが、なぜそれが起こっているのか分かりません。

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 

クライアントモデル：

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 

ドクターモデル：

class Doctor < ActiveRecord::Base 
    belongs_to :client 
end 

問題のビューの一部：

<%= 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> 

Doctor_fields：

<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"> 
      <div class=bs-example data-example-id=striped-table> 
       <table class="table table-striped"> 
        <thead> 
         <tr> 
          <th>Are you a:</th> 
          <th>Yes/No</th> 
          <th>Number of Sessions per week</th> 
          <th>Number of Locations</th> 
         </tr> 
         <tr> 
          <td>Locum</td> 
          <td><%= f.input :gp_locum, as: :radio_buttons, checked: false, label: false %></td> 
          <td><%= f.input :gp_locum_sessions, label: false, required: false %></td> 
          <td><%= f.input :gp_locum_locations, label: false, required: false %></td> 
         </tr> 
      </div> 
    </table> 
</div> 
</div>

Answer 1

[注：link_to_add_associationとhas_oneのに関する一般的発言]

link_to_add_associationは、協会に新しいアイテムを構築しようとします。 has_oneの関係がある場合、これは事実上、存在する場合にはそれを置き換えることを意味します。

は、あなたが本当にlink_to_add_associationに必要がある場合は、次のよう試すことができます。

は

= link_to_add_association 'add doctor', @form_obj, :doctor, force_non_association_create: true 

（これは新しい医者を構築しますが、関連付けを使用していない、これは、コピーされません関連に定義されたいくつかのデフォルトを意味するかもしれませんしかし、フォームの保存後にように選択しない限り、既存の医師が）

に上書きされることはありません[UPDATE：あなたのケースで]

だけshow方法から@client.build_doctorを削除。これは、呼び出されるたびに医師を再初期化します。私はあなたがnew方法でこれをほしいと思うと仮定します。

それとも、私が正しく読んでいるように見える場合、あなただけ

@client.build_doctor unless @client.doctor.present?
