Hi  
I am using the plugin upload column for file uploading…And it was  
working properly with the code  
@sd\_activity\_attachment=ServiceDeskActivityAttachment.new(params[:sd\_activity\_attachment])  
@sd\_activity\_attachment.service\_desk\_activity\_id=@sd\_activity.id.to\_i  
@sd\_activity\_attachment.save  
And in model ServiceDeskActivityAttachment  
upload\_column :attachment, :store\_dir =\> proc{|inst, attachment|  
“uploads/servicedeskactivity/#{inst.id}”}

```
And later according to my requiremnt I changed above controller code

```

and model code as  
@sd\_activity\_attachment=ServiceDeskActivityAttachment.new(params[:sd\_activity\_attachment])  
@sd\_activity\_attachment.service\_desk\_activity\_id=@sd\_activity.id.to\_i  
@sd\_activity\_attachment.company\_name=session[:company] # setting company  
from session to this model to store the respective attachment in company  
specific folder

@sd\_activity\_attachment.save  
And in model  
attr\_accessor :company\_name  
upload\_column :attachment, :store\_dir =\> proc{|inst, attachment|  
“uploads/servicedeskactivity/#{inst.company\_name}/#{inst.id}”}

```
      Now what happens is when i attach a file it goes to

```

RAILSROOT/public/uploads/servicedeskactivity/comp1/hello.jpg  
But I can’t retrieve that file  
And the file points to  
[http://localhost:3000/uploads/servicedeskactivity//1/hello.jpg](http://localhost:3000/uploads/servicedeskactivity//1/hello.jpg)  
instead of

[http://localhost:3000/uploads/servicedeskactivity/comp1/1/hello.jpg](http://localhost:3000/uploads/servicedeskactivity/comp1/1/hello.jpg)  
I figure out where the error is.Please help.Any change  
needed in source code of uploadcolumn?

Thanks in advance  
Sijo

Hey I see that you are storing the image in “uploads/  
servicedeskactivity/#{inst.id}” and you are checking it in “uploads/  
servicedeskactivity/comp1/1/hello.jpg”. Is it a typing mistake or am I  
wrong?. Hope that helps you.
