Hi!
If I have 2 models (Sentence, Word), which have a Many-to-Many
relationship, and Word has a field 'word', the following query:
Sentence.all(:words => { :word => "Hello" })
Tries to match "sentences.id" to "words.id" (live example at
http://pastebin.ca/2097242 ) :
SELECT "id", "text", "book_id"
FROM "sentences"
WHERE "id" IN
(SELECT "words"."id" # Query result will be a single words.id,
which will be used as sentence id
FROM "words"
INNER JOIN "sentence_words" ON "words"."id" =
"sentence_words"."word_id"
INNER JOIN "sentences" ON "sentence_words"."sentence_id" =
"sentences"."id"
WHERE "words"."word" = 'Hello')
ORDER BY "id"
Note that I haven't even heard of DataMapper until today, so I might
doing something bad, but this seems to be definiately wrong (the inner
query should be SELECT "sentences"."id" FROM "words" INNER JOIN...).
Thanks!
Adam
