I got this error:

NoMethodError in PictureController#new

You have a nil object when you didn’t expect it!  
The error occured while evaluating nil.uploaded\_file=

and the line code is here:

@picture.uploaded\_file = @params[‘picture\_file’]

Can you show a little more code so we can see what’s causing the error?  
Are  
you using file\_column? Where did you initialize @picture, etc.

Hello,

You forgot the @ sign in the line where you create a new picture object.

Greetings, Joran.

You left the at-sign off picture when you initialized it. s/b:

@picture = Picture.new
