Ich habe das folgende Beispiel hier gefunden https://bitbucket.org/leafstorm/flask-c ... at=default.
Code: Alles auswählen

from flaskext.couchdb import (CouchDBManager, Document, TextField,
DateTimeField, ViewField, paginate)

COUCHDB_SERVER = 'http://localhost:5984/'
COUCHDB_DATABASE = 'example-guestbook'
SECRET_KEY = 'set this to something secret'
app.config.from_object(__name__)
# model
class Signature(Document):
doc_type = 'signature'
message = TextField()
author = TextField()
time = DateTimeField(default=datetime.datetime.now)
all = ViewField('guestbook', '''
function (doc) {
if (doc.doc_type == 'signature') {
emit(doc.time, doc);
};
}''', descending=True)
manager = CouchDBManager()
manager.add_document(Signature)
manager.setup(app)
# views
@app.route('/')
def display():
page = paginate(Signature.all(), 5, request.args.get('start'))
return render_template('display.html', page=page)
@app.route('/', methods=['POST'])
def post():
message = request.form.get('message')
author = request.form.get('author')
if not message or not author:
flash("You must fill in both a message and an author")
else:
signature = Signature(message=message, author=author)
signature.store()
flash("Signature stored")
return redirect(url_for('display'))
if __name__ == '__main__':
app.config.from_envvar('GUESTBOOK_SETTINGS', silent=True)
app.run(debug=True)
