NoMethodError

Hi, i am trying to build a news feed. The way information is put into
it, is from when the other db i have is updated, that is all working. I
am just having trouble with showing the feed in the view.
  I keep getting this error:


NoMethodError in Admin/post#recent

Showing app/views/admin/post/_feed.rhtml where line #1 raised:

undefined method `fed'' for #<Array:0x35207d0>
Extracted source (around line #1):

1: <%= @newsfeeds.fed %>


this is my view:


<div id="section">
  <span id="titles">News Feed</span> <br/>
<%= render :partial => "feed", :collection => @newsfeeds
%>

</div>



And this is my controller:


 def recent
     @newsfeeds = Newsfeeds.find(:all)
   end


It seems to work it i have it out of a partial and if the controller is
newsfeed.find(:first), but i want to show everything in the db??

Any help would be appreciated,

thanks Will

@newsfeeds is a array  (as the error message tells you). You''re  
rendering a collection, with a partial called ''feed'' which
means that
the element of the array being considered is materialised as a local  
variable called feed. assuming fed is the method you want to call you  
need feed.fed, not @newsfeeds.fed

Thanks for that speedy reply! You were right, now it''s all working
fine.
This was the first time i had named the partial something different to 
what it was containing, so i couldnt work that one out... but thanks 
again!
