2. Writing views in Python

The couchdb-python package comes with a view server to allow you to write views in Python instead of JavaScript. When couchdb-python is installed, it will install a script called couchpy that runs the view server. To enable this for your CouchDB server, add the following section to local.ini:


After restarting CouchDB, the Futon view editor should show python in the language pull-down menu. Here’s some sample view code to get you started:

def fun(doc):
    if 'date' in doc:
        yield doc['date'], doc

Note that the map function uses the Python yield keyword to emit values, where JavaScript views use an emit() function.
