Я попытался получить значения для художника Aphex Twin
Я картировать, используя следующий код:
function(doc){
if(doc.release)
emit(doc.release.artists.artist.name,doc.release.title)
}
Картирование завершено успешно, и я попытался отфильтровать все те значения, которые содержали имя исполнителя «Aphex Twin». Я использовал следующую команду:
function(keys, vals, rereduce) {
for(var i = 0; i < keys.length; i++)
{if(keys[i][0]=="Aphex Twin")
return values[i]
}
}
я получить ответ как
P.S. Если я использую ключи завиток, то я получаю ошибку
curl -X GET http://localhost:5984/smalldiscogs/_design/myvie
ws/_view/Aphextwin?group=false&keys="Aphex Twin"
После того, как все отображенные результаты, я получаю сообщение об ошибке
An incorrect parameter was
entered for the command.
