Unable to edit with papermill

[Enrique Vidal]

Hi,

I am using the latest version of papermill, and I can create attachments with it and display them in my views with no problem, I downloaded the demo app, and read this page and followed along, however I cant seem to be able to use upload_image nor upload_images under edit, the odd thing is that it only gives that problem on my edit action (Im using a partial that I render in both my new and edit action views just like the demo app).

I have double checked my models and controllers againts the demo app and the look alright.

This is the error I get:

Thanks in advance for taking the time to read this.

Here is my post.rb file:

class Post < ActiveRecord::Base
has_many :comments
belongs_to :user

validates_presence_of :title, :body

attr_accessible :title, :body, :timestamp

cattr_reader :per_page
@@per_page = 5

named_scope :latest, :order => 'created_at DESC', :limit => 20

papermill :thumbnail => {:width => 100, :height => 75} # catch-all for non-specified associations, will create assets/asset methods.
papermill :image_gallery, :class_name => ImageAsset, :images_only => true, :thumbnail => {:width => 75, :height => 100}

image_gallery association (set with define_method)

end

[Enrique Vidal]

this is my form code:

<% form_for(@post) do |f| %>
<%= f.error_messages %>

<%= f.label :title %>
<%= f.text_field :title %>

<br />

<%= f.label :body %>
<br / >
<%= f.text_area    :body, :cols => 75, :rows => 35, :class => "mceEditor" %>

<br /><br />

<%= f.label :image_gallery %><br />
<%= f.images_upload(:image_gallery) %><br /><br />

<%= f.label :post_image %><br />
<%= f.image_upload(:post_image) %><br /><br />

<%= f.submit 'Submit' %>

<% end %>

Hello,

I just tried, I found no problem with your code.
The only thing I can think of is your @post is an instance of Array (???) when it should be an ActiveRecord::Base object.
Please check your @post object.

You also obviously have a routing problem (the "Couldn't find Post with ID=edit" part)

Weird. Have you found a solution meanwhile?
