#DQT 2.0

The new Loris Data Query Tool.


Before using this code, you must have the following prerequisites installed

Note: Your version of Erlang should be the most recent version that is compatible with both your CouchDB and Erica


The Easy Way

Create a database on your local CouchDB instance, and clone the code from the server http://couchdb.loris.ca:5984/dataquerytool-$VERSION where $VERSION is separated by underscores rather than dots (because dots are not allowed in CouchDB database names.)


curl -H 'Content-Type: application/json' -X POST http://$YOURCOUCHDBADMIN:$YOURCOUCHADMINPASS@$YOURSERVERNAME:5984/_replicate -d '{"source":"http://couchdb.loris.ca:5984/dataquerytool-1_0_0", "target":"$YOURDATABASENAME"}'

The Hard Way (for development)

First, create a CouchDB database using Futon ( In the following example, the database is named "dqg".

Next, clone this repository:

git clone git@github.com:aces/Data-Query-Tool.git

Finally, push to CouchDB using erica

cd Data-Query-Tool
erica push http://adminuser:adminpass@

Visit to ensure code was pushed.
