A very basic example in Javascript of how to attach a file to a CouchDB document. This will work wether or not the Document ID you define exists.

	A very basic example in Javascript of how to attach a file to a CouchDB document. This will work wether or not the Document ID you define exists.
	Log in at /_utils, upload this file to a document, and then view it for your own uploader. See the code for comments. ajaxSubmit() is the magic that attaches
	as long as the Couch Doc exists because you can't submit a new Couch Document with an attachment.

rjcorwin / create-a-file-and-upload-as-attachment-to-couchdb.js

Created November 15, 2012 15:35

With Javascript, create a new file and send it to a CouchDB database as an attachment to a document

	// With Javascript, create a new file and send it to a CouchDB database as an attachment of a Document

	// Code inspired by "NEW TRICKS IN XMLHTTPREQUEST2" by Eric Bidelman
	// http://www.html5rocks.com/en/tutorials/file/xhr2/

	/*
	* There are two ways of accomplishing this. The first way will always result in a filename of "blob", which is
	* bummer. The second way you will be able to name the file what you want. Note that these examples
	* assume you have the ID of the database, the ID of the Document, and the most recent revision hash of that Document.

An example of using the CouchDB client for PHP (https://github.com/dready92/PHP-on-Couch)

	error_reporting(1);

	// A handy library for talking to CouchDB (https://github.com/dready92/PHP-on-Couch).
	// You could use another library to make pure HTTP calls but sometimes using this couch library is just easier because
	// it is very concise.

	require_once 'couchClient.php';

rjcorwin / TrailDB.md

Last active December 14, 2015 11:39

Idea for a JSON object that lives on the file system. It's like a key value store where your keys forge a trail so clients can find just the data they are looking for without having to use SQL or map reduce. TrailDB?

This JSON object... Check it out.

I ran a .schema on a ka-lite database and tried to prune out the Django specific tables so we can see the data model that ka-lite is working with.

	CREATE TABLE "main_exerciselog" (
	"signed_version" integer NOT NULL,
	"user_id" varchar(32),
	"complete" bool NOT NULL,
	"deleted" bool NOT NULL DEFAULT 0,
	"completion_timestamp" datetime,
	"counter" integer NOT NULL,
	"zone_fallback_id" varchar(32),
	"signature" varchar(360) NOT NULL,
	"signed_by_id" varchar(32),
