Hi  
I have a form like  
\<%= form\_remote\_tag :url =\> { :action =\> ‘attach\_file’,  
:id =\> @sd\_ticket.id },  
:enctype =\> ‘multipart/form-data’ %\>

```
<td width="25%" colspan="4"><%= upload_column_field

```

‘service\_desk\_attachment1’, ‘attachment’ %\>

Attach File \<%=end\_form\_tag %\>

This is not working (the file not uploaded)  
WHAT I GET ON THE CONTROLLER IS AS A RESULT OF

puts params[:service\_desk\_attachment1][:description]  
puts params[:service\_desk\_attachment1][:attachment] IS

file1  
D:\Sijo\file1.txt

BUT THE SAME WAS WORKING WITH THE FOLLOWING .ie JUST WHEN IT WAS  
start\_form\_tag instead of form\_remote\_tag as

\<%= start\_form\_tag ({:action =\> ‘attach\_file’, :id =\> @sd\_ticket.id,  
:method =\> ‘post’}, :enctype =\> ‘multipart/form-data’)%\>

THE ABOVE IS WORKING(the file not uploaded), AND I GET IN THE  
CONTROLLER  
file1  
#StringIO:0x47cee90

WHY THIS HAPPENS  
PLEASE HELP  
Sijo

| \<%= text\_area "service\_desk\_attachment1", "description", "cols" =\> 50, "rows" =\> 1 %\> |

as far as I know, you can’t upload files through an AJAX call. Also,  
start\_form\_tag is deprecated, so you shouldn’t use that anymore.

yes, there is way but you have to use the “iframe remoting pattern” to  
do that

This great tutorial was a great help (just a walktrough):
