Cocoon has_one协会破坏保存/更新使用邪恶的宝石 - Rails

Question

我见过一些类似的问题，但没有涉及到与邪恶的多步使用Cocoon宝石格式与Rails的Gem。当我有has_many关联时，表单可以很好地保存，但是当有has_one关联（Client has_one doctor）时，记录似乎会保存并删除。花了这么长时间试图弄清楚，但只是不明白为什么会发生。

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 

客户端模式：

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：问题

class Doctor < ActiveRecord::Base 
    belongs_to :client 
end 

查看部分：

<%= 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> 

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>

任何帮助将是巨大的感谢！如果你需要其他东西，请告诉我。

Answer 1

[注：约link_to_add_association和HAS_ONE一般性评论]

的link_to_add_association将尝试在该协会建立一个新的项目。如果您有has_one关系，这实际上意味着它将取代现有的，如果有的话。

如果你真的需要link_to_add_association你可以尝试以下方法：

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

（这将建立一个新的医生，但没有使用的关联，这可能意味着在关联定义不会被复制一些默认值，但现有的医生会不会被覆盖，除非打完选择保存形式）

[更新：你的情况]

刚从show方法去除@client.build_doctor 。每次调用医生时，都会重新初始化医生。我假设你只会在new方法中需要这个。

或者，如果我似乎正确地读，你只有一个show没有edit/new这样做

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