Instance Method Details

#display_scribd(object, alt_text_or_attribute = '', alt_text_if_paperclip = nil) ⇒ Object

Displays the scribd object for the attachment on the given object. If alt_text_or_attribute is given, then it will be used as the alternate text for an Attachment_fu model, or as the attribute name for a Paperclip model. If you want to specify alternate text for a Paperclip model, use the last parameter, alt_text_if_paperclip.

If you are using Paperclip, you must specify alt_text_or_attribute as the attribute on which the scribd object exists.

For example, using Attachment_fu:

<%= display_scribd document %>
<%= display_scribd document, 'You need Flash to view this document' %>

Using Paperclip:

<%= display_scribd user, :biography %>
<%= display_scribd user, :biography, 'You need Flash for biographies." %>
