couchdb

问题 I review the Cloud Foundry project and try to install it on a server I will use Couchdb as a database service. My principal question is : How use CouchDB in Cloud Foundry? I install a CF instance with : vcap_dev_setup -c devbox_all.yml -D mydomain.com The devbox.yml contains : $ install : - all. In this install the couchdb_node and the couchdb_gateway is present by default. But it seems to be bug in general. When I delete a app and I have this error for example : $ vmc delete notes2

问题 I have a Json document in cloudant as: { "_id": "3-f812228f45b5f4e4962505561953ew245", "_rev": "3-f812228f45b5f4e496250556195372b2", "wiki_page": "http://en.wikipedia.org/wiki/African_lion", "name": "african lion", "class": "mammal", "diet": "herbivore" } I want to make a search index that can search this document when I input queries as "afrian lion" or "lion african",... 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 have a seemingly correct resource backed by a CouchDB installation. Requests are made using JS Axios. Both Chrome and Safari work, Firefox 65.0 fails however with CORS header 'Access-Control-Allow-Origin' does not match 'http://localhost:8080, *' The server (CouchDB) does, in fact, not deliver 'http://localhost:8080, *' as Access-Control-Allow-Origin but Access-Control-Allow-Origin http://localhost:8080 Access-Control-Expose-Headers content-type, cache-control, a…e-newrev, x-couchdb-body

问题 How would I creat a view equivalent to a SQL query like this? SELECT * FROM bucket WHERE (uid='$uid' AND accepted='Y') OR (uid='$uid' AND authorid='$logginid') My data is stored this way: { "id": 9476183, "authorid": 85490, "content": "some text here", "uid": 41, "accepted": "Y", "time": "2014-12-09 10:44:01", "type": "testimonial" } 回答1: function(doc) { if (doc.accepted == 'Y') { emit(doc.uid, null); } emit([doc.uid, doc.authorid], null); } One request is enough. You can tap view written by

问题 I've been wondering about this for some time. In CouchDB we have some fairly log IDs...eg: "000ab56cb24aef9b817ac98d55695c6a" Now if we're searching for this item and going through the tree structure created by the view. It seems a simple integer as an id would be much faster. If we used 64bit integers it would be a simple CMP followed by a JMP (assuming that the Erlang code was using JIT, but you get my point). For strings, I assume we generate a hash off the ID or something, but at some

问题 Based on a great answer to my previous question, I've partially solved a problem I'm having with CouchDB. This resulted in a new view. Now, the next thing I need to do is remove duplicates from this view while ordering by date. For example, here is how I might query that view: GET http://scoates-test.couchone.com/follow/_design/asset/_view/by_userid_following?endkey=[%22c988a29740241c7d20fc7974be05ec54%22]&startkey=[%22c988a29740241c7d20fc7974be05ec54%22,{}]&descending=true&limit=3 Resulting

问题 Like the title says. I'm sending a simple cUrl cmd from Win7 to CouchDB on my Linux box, and it doesn't work. But if I run the same command in Linux, it works. I'm sending this: curl -X POST 192.168.2.5:5984/test/testdoc -d '{"owner":{"fname":"test","lname":"ing"}}' From windows, it keeps giving me a "error: bad request, reason:invalid UTF-8 JSON". I can run GET commands from windows just fine, I just can't seem to POST to CouchDB. 回答1: Unfortunately, the Windows shell ( cmd.exe ) uses quote

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
