Cool - thank you for that. It makes sense to me now.
What I now have is this:
<%= image_tag ("delete.png") %>
<%= link_to "Delete post?",
{ :controller => "posts", :action => "delete",
:id => @posts.id },
:confirm => "Really delete?" %> |
This successfully deletes the posts, one at a time until they have all
gone. However, once the last post of that user has been deleted, I get
an error:
Called id for nil, which would mistakenly be 4 -- if you really wanted
the id of nil, use object_id
I know this is because it cannot find any posts for that post.id, but
is there a good if else statement i can add to it to render the
profile page once all have been erased?
I've looked over it, but am a bit lost..
THanks again
