Ferret talk - Nov 2006 - Update/Create record only if field is true

I have a sellable flag in my database.  I''m trying to have ferret only
add/update records where sellable == true.  What is the best way to do
this?  I''ve tried editing instance_methods.rb in the AAF, but I still
can''t get it to work.

Thanks for the help

I think I figured it out.  I edited the following:

instance_methods.rb#ferret_create
line 85 I changed to:
 self.class.ferret_index << self.to_doc if !configure[:ignore_flag] or 
self.send(configure[:ignore_flag]) == true

class_methods.rb#rebuild_index
I made the same change to line 199:
  index << rec.to_doc if  !configure[:ignore_flag] or 
self.send(configure[:ignore_flag]) == true

Jens do you think you could add this functionality to AAF in a future 
update?  It would be much appreciated!  Thanks again so much for the 
great plugin.

Cheers!

Whoops, I made a typo above.  Configure should be configuration so the 
changes should actually read

instance_methods.rb#ferret_create
line 85 I changed to:
 self.class.ferret_index << self.to_doc if !configuration[:ignore_flag] 
or
self.send(configuration[:ignore_flag]) == true

class_methods.rb#rebuild_index
I made the same change to line 199:
  index << rec.to_doc if  !configuration[:ignore_flag] or
self.send(configuration[:ignore_flag]) == true

I want to do the same in my app. Is there a way to do this without 
hacking the plugin code?

not a nice one, but using the disable_ferret method you could build a
custom save method that disables ferret for the next save if some 
condition is met, and then saves the record:

def conditional_ferret_save
  disable_ferret if do_not_index? 
  save
end

note that the disable_ferret method disables indexing for this record 
for the next call to save - this is definitely not thread safe, but in 
a Rails context this usually is not a problem.

However I like the idea of having an :if option to acts_as_ferret to
specify a condition (symbol pointing to a method, or a proc) telling
whether indexing should take place or not.
