Ferret talk - May 2006 - acts_as_ferret: dynamic index selection

Hi

What is the be practice regards setting the index path dynamically?

My application needs to switch indexes based on the logged in user, I
put the following before_filter into my controller (the
Document.index_dir method calculates the user''s index path):

before_filter { Document.ferret_configuration[:path] = 
Document.index_dir }

It seems to work, the only rough edge is that the acts_as_ferret
declaration immediately creates a spurious index directory rather than
deferring until the index is actually accessed (and the index path
known), this also means the index directory is not automagically
created.

Cheers, Stuart

P.S. The above didn''t quite work, needed to set index directory in two
places for it to function when adding to the index and searching:

In controller:

  before_filter { Document.set_index_dir }

In the model:

  # Set the Ferret index to that of the current users account.
  def self.set_index_dir
    # Two places are used internally by acts_as_ferret.
    Document.ferret_configuration[:path] = Document.index_dir
    Document.configuration[:index_dir] = Document.index_dir
  end
