Hello everyone,

I’m having problems with :html =\> { :multipart =\> true } in my edit  
form. It doesn’t returns the image in the parameter, so everything  
fails with this errors:

There were problems with the following fields:

```
* Size can't be blank
* Size is not included in the list
* Content type can't be blank
* Content type is not included in the list
* Filename can't be blank

```

A friend of mine said that he had this problem in windows and I am in  
a mac 10.5.6. =/

If I put multipart off it gives the same error. Everything I  
implemented was following attachment\_fu tutorials all over the net.  
This is my edit:

= error\_messages\_for :user, :avatar

- form\_for(@user, :url =\> { :action =\> ‘update’ }, :html =\>  
{ :multipart =\> true }) do |f|  
= f.label “avatar”  
%br  
= f.file\_field :avatar  
%br  
%br  
= f.submit “save image!”

Thx!

The file field must be named “uploaded\_data”, try with that.

Regards.
