Cannot delete for id of type Array

Ruby Apps Ferret
1

Hello list,

I have a little weird error when deleting documents from the index.

I’m using the following code.

ferret_index = Ferret::Index::Index.new(:path => FERRET_INDEX_PATH)
query = Ferret::Search::TermQuery.new(:fk_file_id, “#{_fk_file_id}”)
ferret_index.search_each(query) do | id |
ferret_index.delete(id)
end

And I get the following error
Cannot delete for id of type Array

As I see it the only way this could happened is if search_each
returns an Array of ID’s but it couldn’t right?

I’m using version 0.11.3.

Regards,
Henrik

from the api docs:
search_each(query, options = {}) {|doc, score| …}

you see that ferret hands you two arguments into the block.

Now if you only accept one parameter, Ruby guesses that you want
all parameters as an array. This should yield a warning like
‘multiple values for a block parameter (2 for 1)’
somewhere in your logs.

So just use |id, score| and everything should be fine :slight_smile:

cheers,
Jens

So its that ruby magic trying to figure out what I want again. =)
I was afraid that only using id and not score could be the problem
but I couldn’t see why. Now I know!

Thanks!

This way is a little more direct (untested):

ferret_index = Ferret::Index::IndexWriter.new(:path =>FERRET_INDEX_PATH)
ferret_index.delete(:fk_file_id, _fk_file_id)

Does not work. Delete method only takes 1 argument.

Cheers
