Ruby on Rails

I think your problem is here

<%= form.file_field :files, multiple: true, name: "folder_attachments[files][]"  %>

use "folder_attachment[files][]", note "folder_attachment" singular, not plural since the form is for a single folder_attachment (and that's on your folder_attachment_params method)

ok, the plural got me beyond an error message, but i cant see the uploaded multiuploaded files. singles files work.

controller code:

    @folder_attachment = FolderAttachment.new(folder_attachment_params)
    @folder_attachment.company_id = current_user.cid
    @folder_attachment.user_id = current_user.id
     
     
    @folder = Folder.find_by_id(params[:folder_attachment][:folder_id])
     
    respond_to do |format|
      if @folder_attachment.save
        format.html { redirect_to @folder , notice: 'Attachment was successfully created.' }
      #  format.json { render :show, status: :created, location: @folder_attachment }
      else
        format.html { render :new }
       # format.json { render json: @folder_attachment.errors, status: :unprocessable_entity }
      end
    end

    def folder_attachment_params
      params.require(:folder_attachment).permit(:company_id, :folder_id, :singlefile, :comment,:tags, {files: []})
    end

==========

class FolderAttachmentUploader < CarrierWave::Uploader::Base
  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :file
 
  # storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

any ideas?

thx

Also, use "mount_uploader" singular for the single file and "mount_uploaders" plural for the multiple files

hi,

i want to have one uploader, but 2 forms:

<h3>Upload Single Attachment</h3>
<%= simple_form_for(FolderAttachment.new) do |form| %>
  <%= form.error_notification %>

  <div class="form-inputs">
  <%= form.file_field :singlefile %>
  </div>

  <%= form.input :folder_id , :as => :hidden , :input_html => { :value => @folder_current.id}  if @folder_current %>

  <div class="form-inputs">
  <%= form.input :comment %>
  </div>

  <div class="form-inputs">
  <%= form.input :tags %>
  </div>


  <div class="form-actions">
    <%= form.button :submit %>
  </div>
<% end %>


<h3>Upload Multiple Attachments</h3>
<%= simple_form_for(FolderAttachment.new, :html => { :multipart => true } ) do |form| %>
  <%= form.error_notification %>

  <div class="form-inputs">
  <%= form.file_field :files, multiple: true, name: "folder_attachments[files][]"  %>
  </div>

  <%= form.input :folder_id , :as => :hidden , :input_html => { :value => @folder_current.id}  if @folder_current %>

  <div class="form-actions">
    <%= form.button :submit %>
  </div>
<% end %>

--> no matter what i do, i always get errors on controller leve, eg: map or others. can an uploader only have 1 mount?

class FolderAttachment < ApplicationRecord

belongs_to :folder


  mount_uploaders  :singlefile, FolderAttachmentUploader

mount_uploaders  :files, FolderAttachmentUploader



end

thx
