Cloudant sync android filtered pull

my database has a lot of documents, and each document has a field called doc_type, so i can filter it, but android is giving a error while trying to filter:

Map<String, String> parameters = new HashMap<String, String>();
        parameters.put("doc_type", "doc_company");
        PullFilter filter = new PullFilter("company/list", parameters);
        Replicator replicator = ReplicatorBuilder.pull()
                .from(uri).to(ds)
                .filter(filter)
                .build();

the error:

       CouchException: error: Unknown error, reason: Unknown reason, statusCode: 404, msg: Object Not Found, cause: java.io.FileNotFoundException: https://(my_user_here).cloudant.com:443/db_404040/_changes?style=all_docs&feed=normal&filter=company/filter&doc_type=doc_company&limit=1000

i have the document with filter function:

{
  "_id": "_design/company",
  "_rev": "15-49d2081b2e3c35ae833617fd2356e6d3",
  "views": {
    "list": {
      "map": "function (doc) {\n  emit(doc);\n}"
    },
    "filter": {
      "map": "function (doc, req) {\n  emit(doc._id, 1);\n}"
    }
  },
  "language": "javascript"
}

when i access

https://(my_user_here).cloudant.com:443/db_404040/_changes?style=all_docs&feed=normal&filter=company/filter&doc_type=doc_company&limit=1000

it give me this message:

{"error":"not_found","reason":"missing json key: filters"}

whats wrong? i did exactly what documentation says https://github.com/cloudant/sync-android/blob/master/doc/replication.md (at the end)

Solution

  • i found -> groups.google.com/forum/#!topic/mobile-couchbase/tw5462qMFeM

    i removed the _replicator document from cloudant database(online) and it started to work
