cloudant

问题 I have the following db structure: {"_id": "0096874","genre": ["Adventure","Comedy", "Sci-Fi" ]} {"_id": "0099088","genre": ["Comedy", "Sci-Fi", "Western"]} and like to query it like I could do in mongodb db.movies.find({genre: {$in: ["Comedy"]}}) It works when i use a text index for the whole database, but that seems very wasteful: // index { "index": {}, "type": "text" } //query { "selector": { "genre": { "$in": ["Comedy"] } }, "fields": [ "_id", "genre" ] } The following index does not

I make a function that can return all cases of permutation in "doc.name" for indexing (This function works well and it

问题 I've been trying to find a solution for this requirement but I've hit many dead ends. I'm using Cloudant as my data store of user documents. Each user document has a field (property) called 'items', which is an array of objects. So a user document looks like this: { "_id":"userid1", "_rev":"XX", "username": "foobaruser" "items": [ { "date":1357879144069, "text":"don't cry because it's over, smile because it happened.", "cat":"determination" }, { "date":1357879179209, "text":"those who mind

问题 I was able to successfully query(select) and insert data into Cloudant database using HTTP /REST API. But I am not able to figure out - how to delete and modify documents. For Delete: I tried the following code in nodejs path : '/quick_loan_nosql_db_1?951b05d1b6aa100f4b94e5185674ef40/_rev=1-88963c755157188091f0d30115de18ce' part of the REST API Request with METHOD: DELETE. But when I execute it deletes the entire database instead of the ID being specified. For Update : Can some one provide a

问题 I'm using couchdb4j to establish a connection with couchDB.

问题 I am stuck in retrieving multipart from cloudant using Node JS API. Hence, I used REST API to download the wav file from cloudant database. But its not downloading wav file from https URL. When I enter the https URL directly in browser, it prompts me to save file locally. So, the URL is correct. Here is the code for REST API: var request1 = require('request'); var filestream = fs.createWriteStream("input.wav"); var authenticationHeader = "Basic " + new Buffer(user + ":" + pass).toString(

问题 HI I'm new to cloudant (and couch and asking questions on stackoverflow so I hope I manage to be vaguely clear about what I'm asking ) and I'm trying to do probably the second most basic geo task but am hitting a dead end. I've got a database of docs which are geojson objects, I've created an index so I can query for intersections etc but it seems the only options I have in the url is the format=legacy (gives me the ids) and the format=geojson and the include_docs parameter - what I'd like to

问题 I tried to add cloudant to my app and all of a sudden I can't push it to bluemix anymore. I tracked it down to 1 line which caused the problem: var cloudant = require('cloudant'); prior to this it uploaded with no problems. During the push everything seems fine until it reached the end when it tried to restart the droplet -----> Uploading droplet (20M) 0 of 1 instances running, 1 down 0 of 1 instances running, 1 down 0 of 1 instances running, 1 down 0 of 1 instances running, 1 down 0 of 1
