금지 된 Attibutes 오류 내 Paperclip 개체에

Question

나는 몇 시간 동안이 문제에 대해 내 머리를 두드렸다. 나는 경매를 만들려고 할 때 금지 된 속성 오류가 있습니다. Ive는 도처에 대답을 보았지만 그들 중 누구도 작동하지 않았습니다. ... 나는 지금 금지 얻고

class AuctionsController < ApplicationController 
load_and_authorize_resource 

def index 
end 

def show 
end 

def new 
end 

def edit 
end 

def create 
@auction = Auction.new(auction_params) 
respond_to do |format| 
if @auction.save 
    format.html { redirect_to @auction, notice: 'Auction was successfully created.' } 
    format.json { render action: 'show', status: :created, location: @auction } 
else 
    format.html { render action: 'new' } 
    format.json { render json: @auction.errors, status: :unprocessable_entity } 
end 
end 
end 

def update 
respond_to do |format| 
    if @auction.update(auction_params) 
    format.html { redirect_to @auction, notice: 'Auction was successfully updated.' } 
    format.json { head :no_content } 
    else 
    format.html { render action: 'edit' } 
    format.json { render json: @auction.errors, status: :unprocessable_entity } 
    end 
end 
end 

def destroy 
    @auction.destroy 
    respond_to do |format| 
    format.html { redirect_to auctions_url } 
    format.json { head :no_content } 
    end 
end 

private 

def auction_params 
    params.require(:auction).permit(:title, :price, :image) 
end 
end 

오류 속성 여기 내 전체 컨트롤러입니다 : 여기 내 코드입니다 왜 이런 일이 일어나는지 모르겠습니다. 여기 내 마이그레이션은 다음과 같습니다

class AddAttachmentImageToAuctions < ActiveRecord::Migration 
    def self.up 
    change_table :auctions do |t| 
    t.attachment :image 
end 
end 

def self.down 
remove_attachment :auctions, :image 
end 
end 

여기

class CreateAuctions < ActiveRecord::Migration 
    def change 
    create_table :auctions do |t| 
     t.string :title 
     t.string :price 

     t.timestamps 
    end 
    end 
end 

내 폼의 :

<%= form_for(@auction) do |f| %> 
    <% if @auction.errors.any? %> 
    <div id="error_explanation"> 
     <h2><%= pluralize(@auction.errors.count, "error") %> prohibited this auction from being saved:</h2> 

     <ul> 
     <% @auction.errors.full_messages.each do |msg| %> 
     <li><%= msg %></li> 
     <% end %> 
     </ul> 
    </div> 
    <% end %> 

    <div class="field"> 
    <%= f.label :title %><br> 
    <%= f.text_field :title %> 
    </div> 
    <div class="field"> 
    <%= f.label :price %><br> 
    <%= f.text_field :price %> 
    </div><br /> 
    <div class="field"> 
    <%= f.file_field :image %> 
    </div> 
    <div class="actions"> 
    <%= f.submit %> 
    </div> 
<% end %> 

그리고 난 때문에 매개 변수가 누락 오류 POST 요청에 대한 로그를 얻을 수 없다 ... 죄송합니다. 정확한 오류는 다음과 같습니다. edit :이 오류는 mandeep 덕분에 해결되었습니다. 이제 클립 객체에 대한 바로 금지 속성 오류 : I 양식에 POST 할 때 여기

. 내 컨트롤러에서 마술을 한 두 줄을 놓쳤습니다. 고정 컨트롤러입니다. 이 문제가있는 다른 사람들에게 이것이 도움이되기를 바랍니다.

class AuctionsController < ApplicationController 
    before_action :set_auction, only: [:show, :edit, :update, :destroy] 

    # GET /auctions 
    # GET /auctions.json 
    def index 
    @auctions = Auction.all 
    end 

    # GET /auctions/1 
    # GET /auctions/1.json 
    def show 
    end 

    # GET /auctions/new 
    def new 
    @auction = Auction.new 
    end 

    # GET /auctions/1/edit 
    def edit 
    end 

    # POST /auctions 
    # POST /auctions.json 
    def create 
    @auction = Auction.new(auction_params) 

    respond_to do |format| 
     if @auction.save 
     format.html { redirect_to @auction, notice: 'Auction was successfully created.' }

    end 

    private 
    # Use callbacks to share common setup or constraints between actions. 
    def set_auction 
     @auction = Auction.find(params[:id])

    # Never trust parameters from the scary internet, only allow the white list through. 
    def auction_params 
     params.require(:auction).permit(:title, :price, :image) 
    end 
end
