i am using Carrierwave file upload for uploading and downloading the files. my model:
class InvoiceDetail < ActiveRecord::Base
mount_uploader :attachment, AttachmentUploader
validates :invoice_number, :supplier_name, :attachment, presence: true
validates_uniqueness_of :invoice_number
end
attachment/uploader.rb:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
def filename
"#{model.invoice_number}.#{file.extension}" if original_filename.present? end
invoice_detail/_form.html.erb:
<%= form_for(@invoice_detail , html: {class: 'form-horizontal', role: 'form' }) do |f| %>
<div class="field">
<%= f.label :invoice_number, :class => 'control-label' %>
<div class="controls">
<%= f.text_field :invoice_number, :class => 'text_field' %>
</div>
</div>
<div class="field">
<%= f.label :supplier_name, :class => 'control-label' %>
<div class="controls">
<%= f.text_field :supplier_name, :class => 'text_field' %>
</div>
</div>
<div class="control-group">
<%= f.label :attachment , :class => 'control-label' %>
<div class="controls">
<%= f.file_field :attachment, :class => 'file_field' %>
</div>
</div>
<div class="form-actions">
<%= f.submit "Create Invoice Details", :class => 'btn btn-primary' %>
<%= f.submit "cancel", :class => 'btn btn-danger', method: :delete, data: { confirm: 'Are you sure you want to cancel' } %>
</div>
<% end %>
The present code is working fine with single file upload. Now my requirement is to store multiple files (Multiple file upload) and when I click on download all the multiple files under same id has to be zipped and downloaded.
