Running rails 2.1.0 when I do this:
<%= render :partial => 'style', :collection => @styles %>
I get the collection fine in my index file. When I try the shortcut:
<%= render :partial @styles %>
I get this error:
Couldn't find template file for active_record/named_scope/scopes/ _scope
Any ideas??
Add a comma or not? <%=render :partial, @styles %>
renders nothing.
<%=render :partial=>@styles %> the partial html is : _style.html.erb and the object can be used in the partial erb is style
ya that is what I have.

You could use ruby-debug to break into the partial to check it is getting there. Another thing to do is to check the html produced (view source in browser) to check that it is in fact generating nothing, rather than just nothing that displays.
Presumably you have checked that @styles is not empty?

Ya if I change it to the normal :collection style syntax it works fine.

Ah, I see, I had misunderstood the problem. Is @styles an array of Style objects, and are you rendering from the style controller? Where is _style.html.erb?
What version of Rails are you using? I don't know what version that syntax appeared. Anyone?

Everything is in the styles views directory. rails 2.1.0. I am very confused as this sytnax is supposed to be supported by rails > 2.0. I even tried it in 2.3.2 and the same thing. I watched ryan bates railscasts about 4 times and I still do not know why it is not working.
This works fine:
<%= render :partial => ‘style’, :collection => @styles %>
Which is even more bewildering.
Is there something I'm not getting here? The short form should be either
render :partial => @foo
-or-
render @foo
I've never seen "render :partial @foo"

OP you have changed it to <%=render :partial=>@styles %> as pointed out by Wang Pengcheng?

Hi, what version of Rails is being defined within the environment.rb file?
-Conrad
2.1.0
Hi,
if you’re using Rails 2.1.0 or earlier, you’ll need to use the following syntax:
a) render :partial => partial_name, :collection => @collections
Note: The above requires the partial, _partial_name.html.erb.
b) render :partial => partial_name, :object => @object
Note: The above requires the partial, _partial_name.html.erb.
If you’re using Rails 2.2.2 or greater, then you can use the following
syntax:
a) render :partial => @collections
Note: The above uses the partial, _collection.html.erb.
b) render :partial => @object
Note: The above used the partial, _object.html.erb.
Good luck,
-Conrad
