Hello, i have table AuditLog with fields including: audited_id |
audited_type
That results in data like:
108 | Photo
303 | Comment
What I want to do is create a link to the item, so for the example
above:
<a href="/photos/108">here is the photo</a>
I''m trying to use a polymorphic_path but am getting an error:
"undefined method `model_name'' for Fixnum:Class"
When using:
<%= link_to ''Here she is'',
polymorphic_path([audited_id,
audited_type]) %>
Ideas? Thanks

Interesting, so what I have available is: audited_id = 33 audited_type = Photo So using the polymorphic_path how do I take what I have from the DB AuditLog record and pass an instance of Photo? <%= link_to ''Click to See It!'', polymorphic_path([record.audited_id, record.audited_type]) %> ? Maybe there is a better way to make the link : "/photos/33" based on the data I have? Something like /<%audited_type.pluralize%>/<%audited_id%> Any suggestions? Or is polymorphic_path the right way to go?

Ah shoot, I think the reason it wasn''t working is I had some records in the table that were empty for the polymorphic assoc... I guess it fails if it''s blank.. thank you!
