Cocoon has_one 协会打破 save/update 使用 Wicked Gem - Rails

Cocoon has_one association breaking upon save/update using Wicked Gem - Rails

我看到过一些与此类似的问题,但与在 Rails 中使用 Cocoon gem 和 Wicked 多步骤形式 Gem 无关。当我有一个 has_many 关联时,该表格保存良好,但当有一个 has_one 关联(客户 has_one 医生)时,该记录似乎保存然后删除。花了很长时间试图解决这个问题,但就是看不出为什么会这样。

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

客户端模型:

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>

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>

如有帮助将不胜感激!!如果您还需要什么,请告诉我。

[注意:关于 link_to_add_association 和 has_one]

的一般说明

link_to_add_association 将尝试在关联上建立新项目。如果你有一个 has_one 关系,这实际上意味着它将替换现有的,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

(这将建立一个新医生,但不使用关联,这可能意味着关联上定义的一些默认值不会被复制,但现有医生不会被覆盖,除非在保存表格后选择如此)

[更新:在你的情况下]

只需从 show 方法中删除 @client.build_doctor。每次调用时都会重新初始化医生。我假设您只希望在 new 方法中使用它。

或者,如果我没看错的话,你只有 show 而没有 edit/new 做类似

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