[http://pastie.caboo.se/131759](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.

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 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? fredistic ---
