保存未通過驗證的子字段？

Question

我使用formtastic這樣

class Court < ActiveRecord::Base 
    belongs_to :tournament  
end 

class Tournament < ActiveRecord::Base 
    has_many :courts, :dependent => :destroy 
    accepts_nested_attributes_for :courts, :reject_if => lambda { |a| a[:content].blank? }, :allow_destroy => true 
    validates :name, :presence => true, :length => { :maximum => 100 } 
end 

和所有工作正常，但在比賽中失敗的驗證，形成創建不保留一個失敗的窗體上法庭。

這裏是我的控制器

def new 
    @tournament = Tournament.new 
    1.times do 
    @tournament.courts.build 
    end 

def create 
    @tournament = Tournament.new(params[:tournament]) 

我認爲我可以做這樣的事情，但創建沒有去

if params[:tournament][:courts_attributes] 
     params[:tournament][:courts_attributes].each { |attribute| 
      @tournament.courts.build(attribute) 
     } 
     end 


<%= semantic_form_for @tournament do |f| %> 
    <%= f.inputs do %> 
    <%= f.input :number_courts, :hint => "How many courts are available?" %> 

     <%= f.semantic_fields_for :courts do |builder| %> 
      <%= render :partial => "court_fields", :locals => { :f => builder } %> 
      <span class="links"> 
      <%= link_to_add_fields "Add More Court", f, :courts %> 
      </span> 
     <% end %> 

部分

<div class="nested_fields"> 
<%= f.input :name %> 
<%= f.input :address %> 
<%= f.input :city %> 
<%= f.input :state %> 
<%= f.input :zip %> 
<%= f.input :phone %> 
<%= f.input :contact_name %> 
<%= link_to_remove_fields "Remove Court", f %> 
</div> 

UPDATE ---

他再是我創造的動作

def create 
    @tournament = Tournament.new(params[:tournament]) 
    respond_to do |format| 
    if @tournament.save 
     format.html { redirect_to @tournament, notice: 'Tournament was successfully created.' } 
     format.json { render json: @tournament, status: :created, location: @tournament } 
    else 
     format.html { render action: "new" } 
     end 

這裏也有公正的情況下PARAMS，這將有助於

Processing by TournamentsController#create as HTML 
Parameters: {"utf8"=>"✓", "authenticity_token"=>"xv+p7QdpkJdEUaTGqrKue63869hlwh3Zv1xvkO5qx6A=", "tournament"=>{"name"=>"", "sport_id"=>"1", "entry_fee"=>"", "start_date"=>"", "end_date"=>"", "number_courts"=>"", "courts_attributes"=>{"0"=>{"name"=>"hello", "_destroy"=>"false"}, "1318725283928"=>{"name"=>"asdfsadfas", "_destroy"=>"false"}, "1318725286739"=>{"name"=>"asdfasdfa", "_destroy"=>"false"}}, "available_times"=>"", "available_end_times"=>"", "min_games"=>"", "time_allowed"=>"1:15", "number_teams_per_bracket"=>"1", "gender_id"=>"1", "entry_deadline"=>"", "age_limit"=>"", "rules"=>"", "coach_meeting"=>"0", "meeting_location"=>"", "meeting_date"=>"", "future_tournament"=>"0", "private_service"=>"0", "add_blog"=>"0"}, "commit"=>"Create Tournament"} 

如何在驗證失敗保存數據的任何想法

Answer 1

我認爲當你試圖創建一個錦標賽，並且驗證失敗，它的子級法院實際上並沒有創建。你想要的是法院數據輸入到錦標賽表格中，以保存所有創建嘗試。這聽起來正確嗎？

我還沒有用過formatastic。但是，如果它的API實際上只是由包裝器的Rails的形式幫手，那麼我想給這一個鏡頭：

<%= f.semantic_fields_for :courts do |builder| %> 
     <%= render :partial => "court_fields", :collection => @tournament.courts, :locals => { :f => builder } %> 
     <span class="links"> 
     <%= link_to_add_fields "Add More Court", f, :courts %> 
     </span> 
    <% end %>  

通知換到法院的渲染字段部分。

當您嘗試創建比賽時，這應該使您在TournamentsController.new中創建的球場呈現。當企圖失敗時，它應該使第一次嘗試期間輸入的法院成爲法庭。
