Hello

I am using attachment\_fu and RMagick to raise photos, to change the size  
and to create a thumbnail.

The case that when I add an image, the first time does well and  
rest gives to error when doing save in the controller. So I must stop  
the servant and to return to arranzar it and then raises it…

## My code is this: new.rhtml

# New mugshot

\<%= error\_messages\_for :whatever %\>

\<% form\_for(:mugshot, :url =\> { :action =\> “create” },  
:html =\> { :multipart =\> true }) do |f| -%\>

Upload A Mugshot: \<%= f.file\_field :uploaded\_data %\>

\<%= submit\_tag 'Create' %\>

\<% end -%\>
## Controller

class MugshotsController \< ApplicationController  
def show  
@mugshot = Mugshot.find(:all)  
end

def create  
@mugshot = Mugshot.new(params[:mugshot])  
if @mugshot.save  
flash[:notice] = ‘Photo saved successfully!’  
render :action =\> “show”  
else  
flash[:notice] = ‘There was a problem!’  
render :action =\> “new”  
end  
end  
end

## Model

class Mugshot \< ActiveRecord::Base

has\_attachment :content\_type =\> :image,  
:storage =\> :file\_system,  
:max\_size =\> 2.megabyte,  
:resize\_to =\> ‘640x480\>’,  
:path\_prefix =\> “./public/images”,  
:thumbnails =\> { :thumb =\> ‘100x100\>’ },  
:processor =\> :Rmagick

```
    validates_as_attachment

```

end

I see several things that not if they are correct:

1. The temporary file of the photo is called equal in the cases.  
OK–\> \<File: C: /DOCUME~1/ADMINI~1/CONFIG~1/Temp/CGI5456-1\>  
KO–\> \<File: C: /DOCUME~1/ADMINI~1/CONFIG~1/Temp/CGI5456-1\>

2. In that it has gone well before insert makes “SETH  
SQL\_AUTO\_IS\_NULL=0”.  
Could be a problem of bbdd?

Thank you very much.

Solved the problem.

I have had to change the model.  
It had  
: max\_size =\> 2.megabyte

And it has been solved with  
: size =\> 0.kilobytes…3.megabytes,

Thank you very much

The error is that when I take the servant I can raise a photo, but the  
following ones give error me. And I must reinitiate the servant to be  
able to raise another one…

Thank you very much.
