== CouchRest - CouchDB, close to the metal
|
||
|
||
CouchRest is based on [CouchDB's couch.js test library](http://svn.apache.org/repos/asf/incubator/couchdb/trunk/share/www/script/couch.js), which I find to be concise, clear, and well designed. CouchRest lightly wraps CouchDB's HTTP API, managing JSON serialization, and remembering the URI-paths to CouchDB's API endpoints so you don't have to.
|
||
|
||
CouchRest's lighweight is designed to make a simple base for application and framework-specific object oriented APIs.
|
||
|
||
=== Easy Install
|
||
|
||
sudo gem install jchris-couchrest -s http://gems.github.com
|
||
|
||
=== Relax, it's RESTful
|
||
|
||
The core of Couchrest is Heroku’s excellent REST Client Ruby HTTP wrapper. REST Client takes all the nastyness of Net::HTTP and gives is a pretty face, while still giving you more control than Open-URI. I recommend it anytime you’re interfacing with a well-defined web service.
|
||
|
||
=== Running the Specs
|
||
|
||
The most complete documentation is the spec/ directory. To validate your CouchRest install, from the project root directory run `rake`, or `autotest` (requires RSpec and optionally ZenTest for autotest support).
|
||
|
||
=== Examples
|
||
|
||
Quick Start:
|
||
|
||
# with !, it creates the database if it doesn't already exist
|
||
@db = CouchRest.database!("http://localhost:5984/couchrest-test")
|
||
response = @db.save({:key => 'value', 'another key' => 'another value'})
|
||
doc = @db.get(response['id'])
|
||
puts doc.inspect
|
||
|
||
Bulk Save:
|
||
|
||
@db.bulk_save([
|
||
{"wild" => "and random"},
|
||
{"mild" => "yet local"},
|
||
{"another" => ["set","of","keys"]}
|
||
])
|
||
# returns ids and revs of the current docs
|
||
puts @db.documents.inspect
|
||
|
||
Creating and Querying Views:
|
||
|
||
@db.save({
|
||
"_id" => "_design/first",
|
||
:views => {
|
||
:test => {
|
||
:map => "function(doc){for(var w in doc){ if(!w.match(/^_/))emit(w,doc[w])}}"
|
||
}
|
||
}
|
||
})
|
||
puts @db.view('first/test')['rows'].inspect
|
||
|
||
== CouchRest::Model
|
||
|
||
CouchRest::Model is a module designed along the lines of DataMapper::Resource.
|
||
By subclassing, suddenly you get all sorts of powerful sugar, so that working
|
||
with CouchDB in your Rails or Merb app is no harder than working with the
|
||
standard SQL alternatives. See the CouchRest::Model documentation for an
|
||
example article class that illustrates usage.
