Web Services

We want to be able to access data from the database exported as JSON for easy use within Javascript clients.

This can be done by simply calling the ​RESTlike controller with the var ?format=json:

/sahana/module/resource?format=json           # Lists all records of this resource
/sahana/module/resource/id?format=json        # Display record with record.id==id
/sahana/module/resource/create?format=json    # ToDo
/sahana/module/resource/update/id?format=json # ToDo

The underlying functions are very easy within Web2Py since 1.55:

def display_json():
    "Designed to be called via AJAX to be processed within JS client."
    list=db(db.table.id==t2.id).select(db.table.ALL).json()
    response.view='plain.html'
    return dict(item=list)
