Rails - Jun 2006 - Locating an arbitrary fixture...

Is there a good way to get an arbitrary fixture from the generated 
fixture function?

I need a way to get one of my fixtures, I don''t care which one.  It 
doesn''t need to be random and could always return the same fixture. 
This is part of a support function for custom assertions and it doesn''t
know what class its working on, let alone what fixture names are 
possible.

I''ve tried digging around some in the foxture source file to see
exactly
how they are implemented, but its not quite clear yet.  I''ve been
trying
to do something (very messy) like:
  tmp = 
@@already_loaded_fixtures[self.class][@klass.to_s.downcase.pluralize]

  tmp is now a double nested array.  However it appears to be protected 
in some manner as tmp[0] returns nil.  If I flatten the list, the 
"protection'' is still present.  I can''t access the
elements by index.  I
can''t get at them via tmp.values, etc.  I can iterate via each:
tmp.each
{|x| puts x.inspect } displays the contents.  So it seems like I''m 
definitly trying to get at something in a manner that I shouldn''t be.

All I want is to be able to basically do a
  x = users(:some_user) without knowing either "users" or 
":some_user"... the first part is easy: 
self.send(@klass.to_s.downcase.pluralize, ....?).  If I had a good way 
to get a list of names within the fixture that would complete the 
picture.  Or is there some alternate way that I''m missing...

Any suggestions?

You can use ActiveRecord finders in tests.

  def foo(klass)
    klass.find(1)
  end

  foo(User) #=> user object with id=1
  foo(Post) #=> post object with id=1

That might work better that using named fixtures if you don;t care about 
the names.
