Ruby on Rails

I don't think you can use the same attribute name for single and multiple attachments at the same time. What you can do is to always have multiple files and attach only one file when you get a single file upload. I don't understand the use case of your idea.

yep - its working.

but, can i get the array of filenames in case of multiupload in to the same db field and or vice versa? eg:

mount_uploader  :files, FolderAttachmentUploader
mount_uploaders  :files, FolderAttachmentUploader

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
