Hello,

I’m using the attachment\_fu right now and I don’t know how to get the  
image from session to the browser, before I’ll save it. How to output  
uploaded\_data to the browser?

(I think there are two ways: 1) saving into the temporary file; 2) or  
get it straight from the action; )

Hi Solid. Sorry, could you repeat your question? Attachment\_fu  
automatically knows how to read the “uploaded\_data” part in the file  
field.

Sorry that I were not able to describe my problem a bit better.

I have two controllers questions and answers. When I’m creating a new  
question, I need to add some answers to this question. So I’m going to  
the answer controller and adding some answers with some images to the  
_session_, because I don’t want to save answers at this moment (maybe  
a question will not be created, and also for the easy save… for  
example: @questions.answers = session[:answers] @question.save). So  
I’m adding my answers to the session… and when I’m trying to edit  
this temporary answers, I need to show images for every answer.

The question: how can I output images from the temporary (session)  
answers?

I see only two ways how to do that, but maybe that isn’t a best  
practice.

1. save uploaded\_data to a temporary file (the problem, sometimes we  
need to cleanup the temporary folder);
2. output from some answer action, for example named “temporary\_image”  
the uploaded\_data to a browser.

Thank you again,  
Dmitry
