In my edit view I’ve got an upload image field. When the form is  
submitted it renders the update action with the put method. From what  
I understand the put method updates a resource. So what if there is no  
current image resource to update? Will the put actually look for a  
resource to update, and if it cannot find it will it create the  
resource?  
The reason I ask is because creating an image is optional in my new  
view and create method (the user can create is later when they edit  
the resource).

I’m actually using attachment\_fu with a Photo model. My ‘new’ view has  
several models attached to the ‘User’ within a form. Creating a photo  
on the create User action is optional. Basically I would like the user  
to be able to create a Photo object from the edit view / Update  
action. That’s why I’m wondering if the put method will create an  
object if none is found. If it doesn’t, then would I have to create a  
new method within the ‘edit’ view that will ‘POST’ a new photo?
