Hi all,

when I try to upload a file with 200kb or less, rails does it fine.  
But when I try a bigger one, I get the following error:

ActiveRecord::StatementInvalid in ConteudoController#enviar\_imagem

Mysql::Error: Lost connection to MySQL server during query: INSERT  
INTO conteudo\_imagem (`comentario`, `nome`, `conteudo_id`, `ordem`,  
`tipo`, `data`) VALUES(’’, ‘5.png’, 49, 8, ‘image/png’,  
x’89504e…

Is there a configuration I should do? What is wrong?

thks

Bruno R.

I remember reading (a while back) that rails handles small and large  
files different…

On a quick search I found this…

but there is better info… hope this points you in the right  
direction
