Hello! I am using this example for file uploader.<https://github.com/tors/jquery-fileupload-rails-paperclip-example> Before uploading a file I would like to open it, search for a specific word, assign this word to an attribute in the database and only then save the file in the database.
Example: I select two files and click "upload" The file name is assigned to a upload_file_name. File's size is assigned to an upload_file_size. File is opened, I search for a word "Bug" or "Lion". If i find "Lion", "Lion" should be assigned to an upload_content_type. If I find "Bug", "Bug" should be assigned to upload_content_type. I am not quite sure where I have to define the function that will open a file: in uploads_controller.rb<https://github.com/tors/jquery-fileupload-rails-paperclip-example/blob/master/app/controllers/uploads_controller.rb>or in uploads.rb<https://github.com/tors/jquery-fileupload-rails-paperclip-example/blob/master/app/models/upload.rb>? And I do not know how to assign a "Bug" to an upload_content_type. That is my upload.rb: class Upload < ActiveRecord::Base attr_accessible :upload, :upload_file_name, :upload_file_size Paperclip::interpolates :piks do |attachment, style| attachment.instance.upload_file_name end has_attached_file :upload, :url =>"/system/Files/Files/:piks/:basename.:extension", :path =>":rails_root/public/system/Files/Files/:piks/:basename.:extension" include Rails.application.routes.url_helpers validates :upload_file_name, :presence => true, :format =>{:with => %r{\.(txt)$}i,:message =>"should have an extension .cell"} validates_uniqueness_of :upload_file_name, :message =>"exists already." def to_jq_upload { "name" => (read_attribute(:upload_file_name)).split(".").first, "size" => read_attribute(:upload_file_size), "url" => upload.url(:original), "delete_url" => upload_path(self), "delete_type" => "DELETE" } my uploads_controller.rb: def create p_attr=params[:upload] p_attr[:upload] = params[:upload][:upload].first if params[:upload][:upload].class == Array @upload = Upload.new(p_attr) respond_to do |format| if @upload.save format.html { render :json => [@upload.to_jq_upload].to_json, :content_type => 'BUUUUU', :layout => false } format.json { render json: [@upload.to_jq_upload].to_json, status: :created, location: @upload } else format.html { render action: "new" } format.json{ render json: {name:(@upload.upload_file_name).split(".").first ,error: @upload.errors.messages[:upload_file_name]}, :status =>422} end end end Database: ActiveRecord::Schema.define(:version => 20120731045929) do create_table "uploads", :force => true do |t| t.string "upload_file_name" t.string "upload_content_type" t.string "user" t.integer "upload_file_size" t.datetime "upload_updated_at" t.datetime "created_at", :null => false t.datetime "updated_at", :null => false end end And function to open a file: def check File.open(??filename) do |file| file.each do |line| type=/Lion/.match(line) if type != nil puts(type[0]) #assign to a database!! break end end end end Thanks in advance -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
