Problem rendering several partials from an helper

rubyonrails-talk
#1

Hi guys,

I must be missing something obvious, but I can't get my head around
this:

In a view, if I do:

<% for i in 1..3 %>
   <%= render :partial => 'test' %>
<% end %>

(note: _test just displays a string)

it works just fine. But if I move this into the corresponding helper:

<%= test_helper() %>

with (in the helper):

def test_helper
   for i in 1..3
       render :partial => 'test'
   end
end

it displays in my page:
1..3
as if test_helper had returned the string "1..3".

Any idea what is wrong with this code?

Thanks a lot!
Peter

def test_helper
for i in 1..3
render :partial => 'test'
end
end

it displays in my page:
1..3
as if test_helper had returned the string "1..3".

Which is exactly what it returned - for x in y; end evaluates to y.
You're rendering partials but then discarding the results. You need to
be hanging onto the results of the renders and joining them together
(and then return that)

Thanks a lot Fred. That was it.
