Rails - Dec 2007 - attachment_fu not saving other attributes (like width, height)

http://pastie.caboo.se/131759

I''m only getting the basic filename, product_id for the image, and size
(kb).

I am *not* getting the thumbnail generated (in db or filesystem), nor
is it resizing the image as depicted in the Picture model

| id | parent_id | content_type | filename                   |
thumbnail | size  | width | height | product_id |
---------------------------------------------------------------------------------------------------------------------------------
|  3 |      NULL | image/png    | ico_lh_creds_untrained.png | NULL
  |  3064 |  NULL |   NULL |         21 |
|  4 |      NULL | image/png    | ico_msg_ok.png             | NULL
  |  6662 |  NULL |   NULL |        21 |


I am unclear what I''m doing wrong here.

Please see the source example at http://pastie.caboo.se/131759

You probably don''t have an image processor installed correctly then.

Could it possibly be the way I''m adding the uploaded image?

@product = Product.find(params[:id])
    @product.pictures.build(params[:picture])
    if @product.update_attributes(params[:product])
      flash[:notice] = ''Product was successfully updated.''
      redirect_to :action => ''show'', :id => @product
    else
      render :action => ''edit''
    end


I saw some other posts about a bug with attachment_fu and
update_attributes. How do I ensure I"ve got the image processor
installed properly?

I apologize for jumping the gun. Re-emerging imagemagick and re-
installing "gem install rmagick" fixed the problem.

I am unable however to make the case where an image is optional.

I want to require an image on :create, but make it option
on :edit/:update

I was able to get the effect with this line inside the "update" method
for ProductController:


@product.pictures.build(params[:picture]) unless params[:picture]
[:uploaded_data].blank?

if @product.update_attributes(params[:product])
 ...
end

When I try to validate height and width in my image model (which is
using attachement_fu) it fails validation.  Yet when I examine the
database, those fields are properly filled in.  I''ve removed the
validation for now, yet this bothers me.  I guess attachment_fu must
have overridden the model save! method but I don''t see where this
happens.  Any clues would be appreciated.

Is there a way to validate that the image processor is installed
correctly?  I find that generating thumbnails simply hangs, so I''ve
turned that off while I work on other parts of the project.

I''m developing on windows xp and rails 2.0.2.  Are there any mods or
updates needed for rails 2.0.2?

There is a bug I saw people talk about where you need to add a sleep
1, before you load the picture to your model. Try searching this list
for "attachment_fu windows bug"
