seems pretty simple, my model…

has\_attached\_file :pic\_1, :styles =\> { :thumb =\> “120x90” },  
:url =\> “/:attachment/:id\_:style.:extension”,  
:path =\> “:rails\_root/public/system/:attachment/:id\_:style.:extension”

my view…

\<% form\_tag(:action =\> ‘create’, :html =\> { :multipart =\> true }) do -%\>  
Image  
\<%= file\_field ‘ad’, ‘pic\_1’ %\>  
\<%= submit\_tag ’ Save ', :class =\> ‘button’ %\>

and I save and the development.log shows expected…  
Processing Admin::AdsController#create (for 127.0.0.1 at 2010-02-13  
17:49:15) [POST]  
Parameters: {“html”=\>{“multipart”=\>“true”}, “commit”=\>" Save “,  
“ad”=\>{“salesprogram\_id”=\>“3”, “pic\_1”=\>“DSC01760.JPG”,  
“active”=\>“true”}, “action”=\>“create”, “authenticity\_token”=\>”-",  
“controller”=\>“admin/ads”}

But the SQL Insert for pic\_1\_file\_name, pic\_1\_file\_size,  
pic\_1\_content\_type and pic\_1\_updated\_at are all NULL

and I’ve googled and flailed and googled and flailed but I cannot make  
this work.

Can anyone toss me a bone here?

Parameters: {“html”=\>{“multipart”=\>“true”}, “commit”=\>" Save ",

:html isn’t an option form\_tag understands; use use :multipart =\> true  
for your options hash.

that’s what I get for trying to follow the examples supplied by the  
project…I actually caught it before I read your e-mail and indeed, you  
were right on the mark. The last time I did picture uploads, etc. was  
with Rails 1.2 & rmagick and everyone says how much better paperclip is  
which appears to be the case but I kept looking at the model code  
without ever suspecting that their sample code had the multipart =\> true  
that simply didn’t work.

Thanks

Craig
