Check if your existing model has all the right attributes, such as the
content_type column.

Re: Acts as attachement

are you sure you installed from the correct source. i believe if your 
using edge, its a different version from stock. recheck the 
script/plugin install path.

to upgrade to 1.1.6. We are still on 1.1.2.

Acts as attachement

Hey guys,

I posted this a little while ago but I am still having trouble with it.

I have install acts as attachment. I am using it with one of my existing
models.
Here is the model

class Image < ActiveRecord::Base
  acts_as_attachment :storage => :file_system, :max_size =>
300.kilobytes, :content_type => :image
  validates_as_attachment
end

I have set up the controller to do this...

  def upload_image
    @image = Image.new(params[:image])
    if @image.save
      flash[:notice] = "Image uploaded"
      redirect_to :action => "image"
    else
      flash[:notice] = "Image upload error"
      redirect_to :action => "image"
    end
  end

and this is my view

%= start_form_tag :action => "upload_image", :multipart => true
%>

<p><label for="image_upload">Upload image form my
computer...</lablel>
<br>
<%= file_field("image", "uploaded_data" ) %></p>

<%= render :partial => "license" %>

<%= submit_tag "Upload" %>

I have got the following in my database

    create_table :images do |t|
      t.column :filename, :string
      t.column :size, :integer
      t.column :content_type, :string
      t.column :parent_id,  :integer
      t.column :alt, :string
      t.column :resource_id, :int
      t.column :thumbnail, :string
      t.column :width, :integer
      t.column :height, :integer
      t.column :url, :string
    end

Everytime i go to upload an image i get the following error


undefined method `content_type'' for "image.jpg":String

Any ideas would be great i am really stumped here

I just ran into this myself...

try:

start_form_tag( { :action => "upload_image" }, { :multipart =>
true } )

(i''m using the new 1.2 RC, so it was actually the following for me:

<% form_tag( { :action => "upload_image" }, { :multipart =>
true } )
do %>

)

Make sure you have :multipart => true set correctly in the form tag.
It''s trying to call params[:uploaded_data].content_type
