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; )
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.
save uploaded_data to a temporary file (the problem, sometimes we
need to cleanup the temporary folder);
output from some answer action, for example named “temporary_image”
the uploaded_data to a browser.
