cubicweb-rqlcontroller 0.3.0

restfull rql edition capabilities

Summary

Controller that gives users rql read/ write capabilities.

Sample usage

Users of this service must perform a HTTP POST request to its endpoint, that is the base url of the CubicWeb application instance appended with the “rqlio/1.0” url path.

The posted data must use the application/json MIME type, and contain a list of pairs of the form (rql_string, rql_args), where:

  • rql_string is any valid RQL query that may contain mapping keys with their usual form
  • rql_args is a dictionary, whose keys are the mapping keys from rql_string, and the values can be:
    • actual values
    • string references to a previous RQL query’s result, with the assumption that the referenced RQL query returns a single line and single column rset; under such conditions, a string reference must be “__rXXX” where XXX is the (0-based) index of the RQL query in the json-encoded list of queries.

The HTTP request’s response (in case where there is no error), is a json-encoded list. Its length is the number of RQL queries in the request, and each element contains the json-encoded result set rows from the corresponding query.

In case of an error, a json object with a reason key will explain the problem.

Python client example using python-requests:

import requests
import json

args = [('INSERT CWUser U: U login %(l)s, U upassword %(p)s',
        {'l': 'Babar', 'p': 'cubicweb rulez & 42'}),

       ('INSERT CWGroup G: G name "pachyderms"', {}),

       ('SET U in_group G WHERE U eid %(u)s, G eid %(g)s',
        {'u': '__r0', 'g': '__r1'})
       ]

resp = requests.post('https://myinstance.example.com/rqlio/1.0'),
                     data=json.dumps(args),
                     headers={'Content-Type': 'application/json'})
assert resp.status_code == 200
