Using Paperclip with Rails 3.1.3 no file being added to Paramaters hash on form POST

Question

I am having a strange issue with Rails and Paperclip and I am at my wits end trying to solve it.

I have performed all the steps for adding a Paperclip attachment to my model:

FIRST: db updated with "rails g paperclip listing photo" followed by rake db:migrate, schema looks great



create_table "listings", :force => true do |t|
    t.text     "title"
    t.text     "description"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "photo_file_name"
    t.string   "photo_content_type"
    t.integer  "photo_file_size"
    t.datetime "photo_updated_at"
  end

THEN: added 'has_attached_file :photo' to listing.rb model (I have tried the usual proposed solution I have seen, "photo" to my adding "attr_accessible", but this didnt work for be because, as you'll see below, my problem appears to be different)



class Listing < ActiveRecord::Base

    has_attached_file :photo

    has_many :comments

end

THEN: set up form using multipart and added file_field tag:



<%= form_for(@listing, :html => { :multipart => true }) do |f| %>


<%= f.label :title %>

<%= f.text_area :title %>


<%= f.label :description %>

<%= f.text_area :description %>


<%= f.label :photo %>

<%= f.file_field :photo %>


<%= f.submit %>

<% end %>

Yet when I try to create a listing with a photo attached, I get the following in my logs (Note the lack of any photo element in the Parameters hash):



Started POST "/listings" for 127.0.0.1 at Thu Feb 16 16:14:58 -0400 2012

  SQL (5.4ms)  INSERT INTO "listings" ("created_at", "description", "photo_content_type", "photo_file_name", "photo_file_size", "photo_updated_at", "title", "updated_at") VALUES (?, ?, ?, ?, ?, ?, ?, ?)

[paperclip] Saving attachments.
Redirected to http://localhost:3000/listings/17
Completed 302 Found in 15ms

I have performed a few checks to attempt to figure this out, such as adding another text_area linked to the photo_content_type directly, and I am able to create a listing with a random string directly assigned to that attribute, so I know I can add form elements other than just "title" and "description" that are in the params of the log above.

It seemed as though this question was identical to mine, because I have the exact same steps and issue, except when I noticed that the log from that post at least has the file in the POST parameters... so I believe that is where my problem lies is that my POST somehow does not get the file_field input in its Params.

Fwiw, I have also created a basic test project that is essentially identical (rails 3.1.3, paperclip 2.6.0, all configs the same as far as i can tell) and it worked just fine, so I know my environment is at least OK for Paperclip.

Let me know if there is anything else useful I can provide that I have forgotten to include.

Thanks!

UPDATE:

listings_controller.rb:



class ListingsController < ApplicationController
  # GET /listings
  # GET /listings.json
  def index
    @listings = Listing.all

    respond_to do |format|
      format.html # index.html.erb
      format.json { render :json => @listings }
    end
  end

  # GET /listings/1
  # GET /listings/1.json
  def show
    @listing = Listing.find(params[:id])

    respond_to do |format|
      format.all { render :json => @listing }
    end
  end

  # GET /listings/new
  # GET /listings/new.json
  def new
    @listing = Listing.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render :json => @listing }
    end
  end

  # GET /listings/1/edit
  def edit
    @listing = Listing.find(params[:id])
  end

  # POST /listings
  # POST /listings.json
  def create
    @listing = Listing.new(params[:listing])

    respond_to do |format|
      if @listing.save
        format.html { redirect_to @listing, :notice => 'Listing was successfully created.' }
        format.json { render :json => @listing, :status => :created, :location => @listing }
      else
        format.html { render :action => "new" }
        format.json { render :json => @listing.errors, :status => :unprocessable_entity }
      end
    end
  end

  # PUT /listings/1
  # PUT /listings/1.json
  def update
    @listing = Listing.find(params[:id])

    respond_to do |format|
      if @listing.update_attributes(params[:listing])
        format.html { redirect_to @listing, :notice => 'Listing was successfully updated.' }
        format.json { head :ok }
      else
        format.html { render :action => "edit" }
        format.json { render :json => @listing.errors, :status => :unprocessable_entity }
      end
    end
  end

  # DELETE /listings/1
  # DELETE /listings/1.json
  def destroy
    @listing = Listing.find(params[:id])
    @listing.destroy

    respond_to do |format|
      format.html { redirect_to listings_url }
      format.json { head :ok }
    end
  end
end

UPDATE:

I got to looking at the HTTP Requests for the working and non working versions, and it seems that something on the broken one is causing the browser to interpret the "broken" versions form as application/x-www-form-urlencoded instead of multipart/form-data, despite the rendered forms both appearing to be proper (and the same).
