我一直在努力解決這個問題。我試圖用Dropclip.js上傳多個「照片」模型和paperclip屬性「附件」。目前我正在使用DropZone-Rails gem(我試過幾個版本都有相同的結果)。Dropzone JS在Rails 4中未經允許的參數
# photo.rb
class Photo < ActiveRecord::Base
has_attached_file :attachment, styles: { medium: "720x720>", thumb: "360x360>" }, default_url: "/images/:style/missing.png"
validates_attachment_content_type :attachment, content_type: /\Aimage\/.*\Z/
belongs_to :gallery
belongs_to :user
end
正如您在下面看到的,我已將附件參數列入白名單。
#photos_controller.rb
class PhotosController < ApplicationController
before_action :set_photo, only: [:show, :edit, :update, :destroy]
.........
private
# Use callbacks to share common setup or constraints between actions.
def set_photo
@photo = Photo.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def photo_params
params.require(:photo).permit(:attachment, :gallery_id)
end
懸浮窗負載如預期,此處配置有: Dropzone.autoDiscover = FALSE;
在我的模板:
$("#new_photo").dropzone({
// restrict photo size to a maximum 1MB
maxFilesize: 4,
paramName: "photo[attachment]",
addRemoveLinks: true,
uploadMultiple: true,
success: function(file, response){
$(file.previewTemplate).find('.dz-remove').attr('id', response.fileID);
$(file.previewElement).addClass("dz-success");
}
});
var myDropzone = new Dropzone();
我和懸浮窗的後備形式:
<%= form_for(Photo.new, html: { multipart: true, class: "dropzone"}) do |f| %>
<%= f.hidden_field :gallery_id, :value=>@gallery.id %>
<div class="fallback">
<%= f.file_field :attachment %>
<%= f.submit "Upload" %>
</div>
<% end %>
我的日誌對PARAMS輸出(前得到過濾):
Parameters: {"utf8"=>"✓", "authenticity_token"=>"5ftDcdfB1YpL4UF1fupC/I11xRx3HV5GYih5kshO/KSXzSrZS5Iu1wVRhbLFiyfQWQbwP3R5mxeoJLiM+cUJDg==", "photo"=>{"gallery_id"=>"13", "attachment"=>{"0"=>#<ActionDispatch::Http::UploadedFile:0x007f8058e13c48 @tempfile=#<Tempfile:/var/folders/jb/f02hpkhs3813_b6w_bvyxkxw0000gn/T/RackMultipart20170419-16050-8s5zd8.jpg>, @original_filename="624bbbf5b3c8a293950c8ed24a0c4eef.jpg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"photo[attachment][0]\"; filename=\"624bbbf5b3c8a293950c8ed24a0c4eef.jpg\"\r\nContent-Type: image/jpeg\r\n">}}}
這導致:
Unpermitted parameter: attachment
{"gallery_id"=>"13"}
任何幫助將不勝感激。我搜索了一切,並嘗試了一切,似乎無法使它工作。謝謝。
你是對的!我在這方面花了太多時間。謝謝! – QNeville
