File_column does not work with update model

Rails
1

When I am creating a model, everything works but not during update
(where I use Model.update_attributes(model_attributes) ).
I get the error:

Do not know how to handle a string with value ‘image_xxx.jpg’ that was
passed to a file_column. Check if the form’s encoding has been set to
‘multipart/form-data’.

The form is indeed multipart. Does file_column work with
update_attributes? In the server log I see message:

script/server: No such file or directory - file -bi
“./script/…/config/…/publi
c/temple/image1/tmp/1145739576.129000.3652/image_xxx.JPG”

but the image is there in
/public/temple/image1/tmp/1145739576.129000.3652/ folder.

What could be going wrong here?

The problem has to do with my update method in the controller. I was
doing a find_by_id
in my update and then setting the attributes. This was followed later by
call to update_attributes like below:

def update
@temple = Temple.find(params[:id])
@temple.attributes = params[:temple]
…
…
…
@temple.update_attributes(@temple.attributes)
end

If I take out the call to
@temple.attributes = params[:temple]
and replace it with
@temple.update_attributes(params[:temple)

things are working. So seems like I need to rework my update method
impl.
