couchdb

问题 I could use some help filtering distinct values from a couchdb view. I have a database that stores logs with information about computers. Periodically new logs for a computer are written to the db. A bit simplified i store entries like these: { "name": "NAS", "os": "Linux", "timestamp": "2011-03-03T16:26:39Z", } { "name": "Server1", "os": "Windows", "timestamp": "2011-02-03T19:31:31Z", } { "name": "NAS", "os": "Linux", "timestamp": "2011-02-03T18:21:29Z", } So far i am struggling to filter

问题 Is it possible to manage the sync conflicts from the client? What I mean is, when pouchDB does a sync and detects a conflict, is it possible to get the local doc PouchDB is trying to sync and the last revision of CouchDB doc? If I can get both docs, I can display them to the user and he can choose which version to keep... 回答1: You're in luck, because this is exactly the problem CouchDB and PouchDB were designed to solve. Basically you can read up on the CouchDB docs on conflict resolution.

问题 I want to listen for continuous changes from CouchDB using jQuery - now this works: http://localhost:5984/testdb/_changes?feed=continuous which means that I get a new line of json every time there is a db update - but how do I read updates off this URL using jQuery? I tried using this but it doesn't work: $.ajax( { url : "http://localhost:5984/testdb/_changes?feed=continuous&callback=?", dataType : 'json', success : function(data) { alert(data.results.length); } }); Edit : $.ajax calls the

问题 I'm tryting to decide the best approach for a CouchApp (no middleware). Since there are similarities to my idea, lets assume we have a stackoverflow page stored in a CouchDB. In essence it consists of the actual question on top, answers and commets. Those are basically three layers. There are two ways of storing it. Either within a single document containing a suitable JSON representation of the data, or store each part of the entry within a separate document combining them later through a

问题 I’m trying to extend CouchDB docker image to pre-populate CouchDB (with initial databases, design documents, etc.). In order to create a database named db , I first tried this initial Dockerfile : FROM couchdb RUN curl -X PUT localhost:5984/db but the build failed since couchdb service is not yet started at build time. So I changed it into this: FROM couchdb RUN service couchdb start && \ sleep 3 && \ curl -s -S -X PUT localhost:5984/db && \ curl -s -S localhost:5984/_all_dbs Note: the sleep

问题 In couchdb, I need to represent some data in the following format, a outer container that references other documents inside an array. I want to keep these documents separate as I need to manage conflicts on them individually. { "_id" : "1"' "type" : "container", "items" : [ "1", "2", "3"] } { "_id" : "2", "value": "a" "type" : "item" } { "_id" : "3", "value": "b" "type" : "item" } { "_id" : "4", "value": "c" "type" : "item" } I want to output a view of the data in the following format. { "_id

问题 I am live syncing a freshly minted pouchdb (3.3.1) to an established (iris) couchdb. The initial replication happens successfully ( pause event fired). If I do info() on the Local, I get an update_seq of 362 . If I do info() on the remote, it shows an update_seq of 4201 . I think this makes sense to me: the local db has no revisions - only the leaves (i.e. there are 362 leaves in the db) whereas the remote db sequence counter reflects all the historical changes that have been made since it

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 months ago . I'm pretty new to CouchDB. I have googled without finding a database viewer for CouchDB. How do you view a CouchDB database without manipulating the raw HTTP messages ? Ideally, the tool would meet the following requirements : Cross-platform (Windows or Linux mainly) Desktop application or Web application Allow
