Display PDF's uploaded with paperclip

I upload files (PDF's only) using paperclip and now want to display these as a PDF in a view.

This gives me an empty frame <iframe src="<% @document.file %>"></iframe> This results in an image <%= image_tag @document.file(:large) %>

the files are stored in postgress.

Solution

You have an syntax "issue":

<iframe src="<% @document.file %>"></iframe>

Should be

<iframe src="<%= @document.file %>"></iframe>
<!-- notice the equals symbol (=) -->
<!-- which prints something into erb file. -->

Also, I believe you need to use it's url, so I'd be something like this:

<iframe src="<%= @document.file.url(:large) %>"></iframe>
