♚ Throne

The king is here - on his couch, covered in rubies.

Simple library for working with CouchDB

Caution!

This code is in heavy development, in conjunction with a few development projects. This means the API can and probably will change substantially over the next few releases as we work out what fits best. You have been warned.

API documentation

Basic Usage

Create a database object to work with. Will create the DB if it doesn’t exist

@db = Throne::Database.new('http://localhost:5984/throne-test')
# if you don't want to create the DB if it doesn't exist:
@db = Throne::Database.new('http://localhost:5984/throne-test', false)

Save a new document

id = @db.save({:document_title => 'New Document', :documents => 'are just a hash')
id_of_document_saved = id
revision_of_document_saved = id.revision

Get a document

doc = @db.get(document_id)
# with revision
doc = @db.get(document_id, revision)

Save an existing document

id = @db.save(existing_document_loaded_from_db)
new_revision = id.revision

Delete a document

@db.delete(document_id_or_document_object)

Run a design document/function

res = @db.function('_design/DesignDoc/_view/viewname')
res
=> An array of documents
res.offset
=> couchdb offset data

# with parameters
@db.function('_design/DD/_list/listname/viewname', :key => ab..fg, :xyz => 7)
=> An array of documents

# Iterator Method
@db.function('_design/DesignDoc/_view/viewname') do |doc|
  #invoked for each document
  p doc
end

# All documents
@db.function('_all_docs')
=> All docs in the database

Delete the database

@db.delete_database

Create the database

@db.create_database

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don’t break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
