Rails CRUD error

So my experience is in Java web services, but I am trying to make a transition to ROR.

I am using FlexImage to handle loading images and creating thumbnails. I followed the explorer and the CRUD behavior worked fine at one point. However, at some point, the CRUD behavior for one of my models (images) was broken.

The error code I am returning looks like this: ActiveRecord::RecordNotFound in ImagesController#show -- Couldn't find Image with ID=#<Image:0x4e2bd74>.

In other words, when I tell Rails about create / update / destroy, it confuses the object with the ID. This indicates that a routing problem may arise. I thought adding partial images might be a problem, but rolling back the changes won't fix it.

Following are the new controller show and update methods for the Images model:

      # images_controller.rb

        # ...

      def new
        @image = Image.new

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

    # ...
  def show
    @image = Image.find(params[:id])

    respond_to do |format|
      format.jpg  # show.jpg.erb 
      format.html # show.html.erb
      format.xml  { render :xml => @image }
    end
  end



    # ...

      def create
        @image = Image.new(params[:image])

        if @image.save 
        redirect_to image_url(@image)
        else
        flash[:notice] = 'Your image did not pass validation.'
        render :action => 'new'
        end
      end 
     # ...

      

        
        
        
      

    

Note that show () expects a matching ID of course. Here's new.html.erb to load a new image:

# new.html.erb [upload image]
<h1>New image</h1>

<% form_for @image, :html => { :multipart => true } do |f| %>
  <%= f.error_messages %>
  <table><tr><td width="50%">
  <p>
    <%= f.label :filename %><br />
    <%= f.text_field :filename %></p>
  </td>
  <td><p><b>Upload Image</b><br />
    <%= f.file_field :image_file %><br />
    or URL: <%= f.text_field :image_file_url %>
    <%= f.hidden_field :image_file_temp %>
  </td>
  <td>
    <b>Uploaded Image:</b><br />
    <%= embedded_image_tag(@image.operate { |img| img.resize 100 }) if @image.has_image? %>
  </td>
  </tr>

  </table>
  <p>
    <%= f.label :description %><br />
    <%= f.text_area :description %>
  </p>
  <p>
    <%= f.submit 'Create' %>
  </p>
<% end %>

<%= link_to 'Back', images_path %>

      

        
        
        
      

    

The relevant part of the .rb routes looks like this:

# routes.rb [excerpt]

  map.resources :images
  map.image 'images/:action/:id.:format', :controller => 'images'

      

        
        
        
      

    

Also note that the new image does indeed load , and the error is pushed to the redirect to show (which expects a valid id in the [: id] parameters, not the object it is being served for whatever reason.)

Thanks for your help in advance, and please let me know if anything comes up with you.
