Attachment_fu not saving other attributes (like width, height)

Rails
1

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 Parked at Loopia

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

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

Enclose the image upload in its own form

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”
