partial wont render .html.erb

Hi, My partial simply wont render a .html.erb file. This is exactly
what I get on the error screen:

ActionView::MissingTemplate in Categories#show

Showing app/views/categories/show.html.erb where line #7 raised:

Missing template tutorials/_tutorial.erb in view path app/views

Extracted source (around line #7):

4: </p>
5: <h2>Tutorials</h2>
6: <div id="tutorials">
7: <%= render :partial => @category.tutorials %>
8: </div>
9:
10: <h2>New Tutorial</h2>

Hi, My partial simply wont render a .html.erb file. This is exactly
what I get on the error screen:

ActionView::MissingTemplate in Categories#show

Showing app/views/categories/show.html.erb where line #7 raised:

Missing template tutorials/_tutorial.erb in view path app/views

Have you got a tutorials/_tutorial.erb in app/views?

Colin

Yes..

I really cant think what might be wrong... Does anyone know what is
wrong here?

Yes..

What is the value of @category.tutorials ( I presume this is a string
but why it is named as a plural )?

Colin

My guess is that your syntax is incorrect and you are missing the name
of the partial to render itself and also either the :object
or :collection symbols.

This is from the documentation to rendering partials, in case it
helps:

  # Renders the same partial with a local variable.
  render :partial => "person", :locals => { :name => "david" }

  # Renders the partial, making @new_person available through
  # the local variable 'person'
  render :partial => "person", :object => @new_person

  # Renders a collection of the same partial by making each element
  # of @winners available through the local variable "person" as it
  # builds the complete response.
  render :partial => "person", :collection => @winners

  # Renders a collection of partials but with a custom local variable
name
  render :partial => "admin_person", :collection => @winners, :as
=> :person

  # Renders the same collection of partials, but also renders the
  # person_divider partial between each person partial.
  render :partial => "person", :collection =>
@winners, :spacer_template => "person_divider"

  # Renders a collection of partials located in a view subfolder
  # outside of our current controller. In this example we will be
  # rendering app/views/shared/_note.r(html|xml) Inside the partial
  # each element of @new_notes is available as the local var "note".
  render :partial => "shared/note", :collection => @new_notes

  # Renders the partial with a status code of 500 (internal error).
  render :partial => "broken", :status => 500

Yes..

Is it definitely in views/tutorials rather than views/categories?

Does the alternative syntax work:
render :partial => "tutorials/tutorial", :collection => @category.tutorials
