问题 Would the following be a viable strategy for implementing versioning(using "example" as a sample document type): Have one original document where the type field is named example_original. Subsequent changes to the document all have type example_change and the id of example_original document as a key. The change would also carry a timestamp. Keep one doc with type example_current that is the result of example_original with all example_change "applied". A new example_change document would

问题 I'm using HttpClient 0.6.0 from NuGet. I have the following C# code: var client = new HttpClient(new WebRequestHandler() { CachePolicy = new HttpRequestCachePolicy(HttpRequestCacheLevel.CacheIfAvailable) }); client.GetAsync("http://myservice/asdf"); The service (this time CouchDB) returns an ETag value and status code 200 OK.

问题 Couchdb only parse application/x-www-form-urlencoded. Is there a FormData() attribute that set the enctype? xhr.open('put',document.myForm.action,false) xhr.setRequestHeader('Content-Type','application/x-www-form-urlencoded') xhr.send(new FormData(document.myForm)) 回答1: No, the XHR2 "send" method is specified to always send FormData objects as multipart/form-data. As ampersand suggests, one option would be to use the jquery.couch.js plugin that's built into every CouchDB instance within Futon

问题 Can .NET (managed code) read and write to CouchDB? I would like to build a part of my project that does document management using CouchDB 回答1: Take a look at the SharpCouch utility class. It is a simple wrapper class for the CouchDB HTTP API. 回答2: Its a late answer, but do check out Hammock.

You don't even need an 'id'

问题 Suppose that I want to customize the indentation rules of the foton document editor, where and how can I do that? I'll elaborate. The foton editor lays out document like this: (which to my flavor is completely annoying) { "_id": "1326017821636", "_rev": "2-51ab614953437181a24f1c073fbc6201", "doc_type": 0, "step": 2, "data": { "map1": { "attr1": 73031, "attr2": "strval" }, "map2": { "att1": 52001, "att2": "strval" }, "mapmap": { "map": { "id11": { "id": "id11", "attr": "attr", "attr2": 2222 },

问题 I am working on an application that runs on multiple clients that talk to one main MySQL database. Additionally, we have a web application that uses the same MySQL database.

The clients only read from table A, and write to table B. The web application writes both to tables A and B. How should I setup a
