入れ子になったフォームを編集するときに重複を作成するレール

Question

私はたくさんのグーグルで行いましたが、許可された属性にidを追加することに戻ってきましたが、それは私のケースでは機能しません： 複数の空の行ネストされたフォームを編集するときに関連テーブルの中の） フォームを編集するたびに、関連する空のレコードが2倍になります。

私はそれので、全体_formが含まれていませんでした非常に長いです（300行）が、あなたに考えを与える：

<div class="form-group "> 

     <div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true"> 

      <%= f.fields_for :applicant do |a| %> 

       <div class="panel-group" id="accordion" role="tablist" aria-multiselectable="true"> 
       <div class="panel panel-default">

        <h4 class="panel-title"> 
         <a role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseOne" aria-expanded="true" aria-controls="collapseOne"> 
         Aanvraag 
         </a> 
        </h4> 
        </div> 
        <div id="collapseOne" class="panel-collapse collapse in" role="tabpanel" aria-labelledby="headingOne">

Answer 1

ネストされた各属性にreject_if句を追加する必要があります。また、フォームでネストされた属性を黙って拒否しないようにする場合は、必要なフィールドの個々のモデルに検証を追加できます。必要に応じて指定したもののエラーを取り消します。サイドノートでは

has_many :tools, dependent: :destroy 
accepts_nested_attributes_for :tools, reject_if: :all_blank 

has_many :controls, dependent: :destroy 
accepts_nested_attributes_for :controls, reject_if: :all_blank 

has_one :applicant, dependent: :destroy 
accepts_nested_attributes_for :applicant, reject_if: :all_blank 

has_one :contractor, through: :applicant 

has_many :signatures, dependent: :destroy 
accepts_nested_attributes_for :signatures, reject_if: :all_blank 

has_many :representatives , through: :signatures, :source => :representatives 

has_many :gasmeters, dependent: :destroy 
accepts_nested_attributes_for :gasmeters, reject_if: :all_blank 

、私は、ネストされたフォームで作業する場合cocoon gemは非常に有用であることがわかってきました。

Answer 2

あなたはこのような何かをする必要があります

def update 
    @enquiry = Enquiry.find(params[:id]) 
    if @enquiry.update_attributes(enquiry_params) 
    # Handle a successful update. 
    else 
    render 'edit' 
end 

とenquiry_paramsからIDを削除します。
