I want to allow the user to preview the posts they’re making. Easy  
enough to do with text and a single model. However, now I want to  
allow posting of (multiple) attachments per post. My models:

class Post \< ActiveRecord::Base  
has\_many :attachments  
…  
end

class Attachment \< ActiveRecord::Base  
has\_attachment :content\_type =\> :image,  
… etc…  
validates\_as\_attachment  
belongs\_to :post  
end

The problem is I don’t actually want to create new records in the  
attachments table until the user submit the post, but I can’t use all  
the attachment\_fu goodness to show the images in a preview unless I  
create the attachments first. Suggestions?

Thanks in advance.

thanks, but it sounds like you just have a Photo model, as opposed to  
one that belongs\_to another model? my situation is a little trickier  
because I don’t want to create the photos until the user is sure he  
wants to create the post the photos belongs\_to
