Paperclip not called when uploading attachment, so attachment is not saved. Rails3 + uploadify

Question

I have two different apps using paperclip. On the app that does not save attachment or call paperclip, i get this log when i upload an app

On the app where paperclip works fine, i get this log:

The only difference between the two is that the one not working is polymorphic model and the controller for the polymorphic model is below:

class UploadsController < ApplicationController
  before_filter :find_parent
  before_filter :prepare_input_params
  #respond_to :html, :json, :js

  def index
     @uploads = Upload.all
 #@uploads = @parent.try(:uploads).try(:all)
 @upload = Upload.new
     #respond_with([@parent, @uploads])
  end

  def new
     @upload = @parent.uploads.new
  end

  def create 
     @upload = @parent.uploads.build(params[:upload])   
   if @upload.save
        flash[:notice] = "sucessfully saved upload"     
    respond_to do |format|
        format.html {redirect_to [@parent, :uploads]}
        format.json {render :json => { :result => 'success', :upload =>  polymorphic_url([@parent,:uploads])  } }
      end   
  else
      render :action => 'new'
      end
 end

 def edit
   @upload = Upload.find(params[:id])   
 end

 def show
   "puts @upload.inspect"
     @upload = @parent.uploads.find(params[:id])
     @total_uploads = @parent.uploads.find(:all, :conditions => { :user_id =>  @upload.user.id})
 end

 def update
   @upload = Upload.find(params[:id])
    if @upload.update_attributes(params[:upload])
     flash[:notice] = "Successfully updated document"
     redirect_to @upload
    else
     render :action => 'edit'
    end
 end

 def destroy
   @upload = Upload.find(params[:id])
   @upload.destroy
   redirect_to([@parent, :upload])
 end 

 private 
 def prepare_input_params
   params[:upload][:document] = params[:Filedata] if params[:Filedata]
 end

end

Here is the gist file with the form partial and uploadify bit: https://gist.github.com/940960. The form has :html => { :multipart => true }.

Thanks for the help.

EDIT:

It seems the problem is from the model, uploads.rb. When i comment out the section below: everything works, but i need to be able to use validations and specify path as i want to use S3. Anyhelp on how i can uncomment the code without the initial error of paperclip not saving happening again.

class Upload < ActiveRecord::Base
 attr_accessible  :document
 belongs_to :uploadable,  :polymorphic => true
 has_attached_file :document, :styles => { :small => "150x150>",:thumb => "100x100>" }
=begin                 
             :url => "/uploads/:id/:style/:basename.:extension",
             :path => ":rails.root/public/:uploads/:id/:style/:basement.:extension"                                  
validates_attachment_presence :document
validates_attachment_size  :document, :less_than => 5.megabytes
validates_attachment_content_type :document, :content_type => ['application/octet-stream','image/jpeg','image/gif', 'image/png', 'image/pdf', 'image/doc', 
                                                             'video/x-m4v', 'video/quicktime','application/x-shockwave-flash', 'audio/mpeg', 'video/mpeg', 'application/pdf','application/msword']

=end

end

Update:

I think the main problem seem to be that why attaching a new file, paperclip, somehow starts calling SELECT "uploads".*'from "uploads" instead of calling INSERT INTO 'uploads', that is controller#create action shown higher up seems to be calling SELECT, whenever ever i provide :url and :path options to paperclip has_attached_file method. See the log below:

Based on @CharlieMezak's request, here is the views/uploads/_form.html.erb:

</br>
<%= form_for [parent, upload], :html => { :multipart => true } do |f|  %>
<div class="field">
<%= f.label :document %><br />
<%= f.file_field :document %>
</div>

<div class="actions">
<%= f.submit "Upload"%>
</div>

views/uploads/new.html.erb:

<%= render 'form', :parent => @parent, :upload => @upload %>

views/users/index.html.erb:

<%= render "uploads/form", :parent => user, :upload => user.uploads.new %>

More Update :

Like i mentioned, when i comment out the :styles, : :url and :path options from paperclips's **'has_many_attachment :document', the INSERT statement is called and though it saves the file, instead of displaying the attached file, it ends up displaying several parameters like authenticity tokens etc on the website as shown below:

attributes:
id: 1

Answer 1

Did you remember to add :multipart => true to the form tag in your view?

Answer 2

Try adding :document_file_name to the attr_accessible call.

Answer 3

One thing I noticed is there is a typo on line 17 of uploadify in your gist. You have dat.upload, probably should be data.upload?

Also, have you tried uncommenting the validations one at a time? Let me know what happens. I've had my fair share of battles versus Paperclip.

Answer 4

I'm doing exactly the same kind of thing as you are, but using the aws-s3 gem to help me upload to S3 via paperclip. This is what's in my model:

has_attached_file :image,
                :storage => :s3,
                :s3_credentials => "#{Rails.root.to_s}/config/s3.yml",
                :bucket => "your_s3_bucket_name",
                :path => ":attachment/:id/:style/:filename"

And I have this in my gemfile:

gem "paperclip", "~> 2.3"

gem "aws-s3"

And in my groups table:

t.string   "image_file_name"
t.string   "image_content_type"
t.integer  "image_file_size"
t.datetime "image_updated_at"
