ArgumentError Exception：間違った引数の数（指定した2、予想される1）画像をアップロードしようとしたとき（レール4;クリップ5;クリップクリップのメタ）

Question

ファイルをアップロードしようとしたときにArgumentError Exception：wrong議論の数（与えられた2、期待される1）

すべてが正常に動作する前に。私は更新後この動作に気づいたpaperclipバージョン5.0.0に

ここに私のコードです。

モデル/ image.rb

class Image < ActiveRecord::Base 
    belongs_to :imageable, polymorphic: true 

    has_attached_file :attachment, styles: { 
            main_large: "628x329>", main_small: "628x329>", 
            object_large: "1200x1200>", object_small: "177x120", 
            catalog: "397x312>", thumb: "100x100>" 
           }, default_url: "/images/:style/missing.png" 

    validates_attachment :attachment, content_type: { content_type: /\Aimage\/.*\Z/ }, 
            size: { in: 0..10.megabytes } 
end 

モデル/ estate.rb

class Estate < ActiveRecord::Base 
    has_many :images, as: :imageable, dependent: :destroy, autosave: true 

    accepts_nested_attributes_for :images, reject_if: :reject_images, allow_destroy: true 

    private 

    def reject_images(attributes) 
    attributes['attachment'].blank? 
    end 
end 

コントローラ/ estates_controller.rb

class EstatesController < ApplicationController 
    before_action :set_estate, only: :update 

    def update 
    respond_to do |format| 
     if @estate.update(estate_params) 
     if params[:image] 
      # This is where I get an exception 
      @image = @estate.images.create(image_params) 
     end 
     format.html { redirect_to @estate, notice: t(:estate_updated) } 
     else 
     format.html { render :edit } 
     end 
    end 
    end 

    private 

    def set_estate 
    @estate = Estate.find_by_id(params[:id]) 
    end 

    def estate_attributes 
    %i[title address] 
    end 

    def image_attributes 
    %i[attachment name] 
    end 

    def estate_params 
    params.require(:estate).permit(*estate_attributes, image_attributes: image_attributes) 
    end 

    def image_params 
    params.require(:image).permit(*image_attributes) 
    end 
end 

の農園/ _form.haml

= simple_form_for @estate, :html => { multipart: true} do |f| 
    = f.input :title 
    = f.input :address 
    = f.label :images 
    = file_field_tag :attachment, type: :file, multiple: true, name: 'image[attachment]' 
    = f.button :submit, class: 'expand' 

image_params値ここ

{"attachment"=>#<ActionDispatch::Http::UploadedFile:0x007fdb1627e518 @tempfile=#<Tempfile:/var/folders/sk/74r24jps5_j1f5q9y_6fd51w0000gn/T/RackMultipart20160908-4298-1isgwun.jpg>, @original_filename="villa_preview4.jpg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"image[attachment]\"; filename=\"villa_preview4.jpg\"\r\nContent-Type: image/jpeg\r\n">} 

は私がimage_paramsでImage.newを呼び出そうとすると、私はこれを取得していますバックトレース

更新： 基本的にはすべてのものがImageオブジェクトを作成することに帰着します。 このようなコンソールで試してみると、同じエラーが発生します。 http://api.rubyonrails.org/classes/ActionDispatch/TestProcess.html#method-i-fixture_file_upload

Image.create(
    attachment: Rack::Test::UploadedFile.new("#{Rails.root}/lib/files/images/sample.jpg", 'image/jpg') 
) 

私はmime_typeのparamを削除する場合しかし、すべてが正常に動作します。

Image.create(
    attachment: Rack::Test::UploadedFile.new("#{Rails.root}/lib/files/images/sample.jpg") 
) 

実際のシナリオでどのように動作させることができますか？

Answer 1

問題はpaperclip-meta gemにありました。画像の寸法を取得するために、メタデータattachment_metaの列が追加されました。

image.rb（ありがとうございましたPaperclip wiki）のリファクタリングの後、私はそれを動作させることができました。

class Image < ActiveRecord::Base 
    belongs_to :imageable, polymorphic: true, required: false 

    has_attached_file :attachment, styles: { main_large: "628x329>", main_small: "628x329>", 
              object_large: "1200x1200>", object_small: "177x120", 
              catalog: "397x312>", thumb: "100x100>" } 

    validates_attachment :attachment, content_type: { content_type: /\Aimage\/.*\Z/ }, 
            size: { in: 0..10.megabytes } 

    before_save :extract_dimensions 
    serialize :dimensions 

    # Helper method to determine whether or not an attachment is an image. 
    # @note Use only if you have a generic asset-type model that can handle different file types. 
    def image? 
    attachment_content_type =~ %r{^(image|(x-)?application)/(bmp|gif|jpeg|jpg|pjpeg|png|x-png)$} 
    end 

    private 

    # Retrieves dimensions for image assets 
    # @note Do this after resize operations to account for auto-orientation. 
    def extract_dimensions 
    return unless image? 
    tempfile = attachment.queued_for_write[:original] 
    unless tempfile.nil? 
     geometry = Paperclip::Geometry.from_file(tempfile) 
     self.dimensions = [geometry.width.to_i, geometry.height.to_i].join('x') 
    end 
    end 
end
