Render :partial problems

I just started using rails, and following I got a little blog going, almost… until i hit the part where he starts with the ‘render: partial" stuff… so, in my script, i have
<%= render :partial => “post”, :collection => @posts %>
and then it out puts the error
’No rhtml, rxml, or delegate template found for partialpostcollection#Post:0x4093ada8#Post:0x4093ace0#Post:0x4093ac18

any one else had a problem like this? has ne one else got ‘render :partial’ to work properly??

i tried using render_partial … but i had problems there too…

also, does ne one know of ne rails/ruby forums and good tutorials (aside from the rails site)
