Contribution:
bottle2
Headline
An extension of Contribution:py3k, using Technology:Bottle as a framework for Feature:Web UI.
Characteristics
The most prominent feature of this contribution is the Feature:Web UI. The Server is implemented using Bottle and communicates with the Client using the Web UI REST API.
Illustration
Technology:Bottle uses route handlers to apply incoming connections to specified functions.
# When a client GETs the root URL, send the default client page
@get('/')
def index():
return static file('web ui.html', './public')
# Sends the model to the client (the request is usually made via AJAX)
@post('/')
def config():
return web ui
Each action from the client is handled via such a route handler.
Take for example the handler for Feature:Cut:
@post('/cut')
def cut():
# Get the node to start cutting from
obj, error = object from('id')
if not obj: return error
# Aggregate the employees that have been cut so the client can update them
commands = []
for employee in obj.cut():
# Manual conversion of employees to JSON
commands.append({'type' : 'edit', 'node' : employee.to json()})
# Send AJAX response
return {'commands' : commands}
Relationships
- Contribution:jsTree is the default Client for this contribution.
- Contribution:py3k was the base inspiration for this contribution, but the resemblance isn't too recognizable anymore.
- Contribution:dancer is a similar Server, using Language:Perl and Technology:Dancer instead.
Architecture
The model-related classes and validator are both separate Python modules. The server itself is just a single Python script.
Usage
Please see the readme.md on GitHub for details.
