add value in data group via REST API

It is the only way. Data-group records are not subcollections, so in order to replace one you have to replace them all. Here's some code I wrote for expanding and contracting data groups a while back in python:

def get_dg(rq, url, dg_details):
    dg = rq.get('%s/ltm/data-group/%s/%s' % (url, dg_details[0], dg_details[1])).json()
    return dg

def extend_dg(rq, url, dg_details, additional_records):
    dg = rq.get('%s/ltm/data-group/%s/%s' % (url, dg_details[0], dg_details[1])).json()

    current_records = dg['records']
    new_records = []
    for record in current_records:
        nr = [ {'name': record['name']}]
        new_records.extend(nr)
    for record in additional_records:
        nr = [ {'name': record}]
        new_records.extend(nr)

    payload = {}
    payload['records'] = new_records
    rq.put('%s/ltm/data-group/%s/%s' % (url, dg_details[0], dg_details[1]), json.dumps(payload))

def contract_dg(rq, url, dg_details, removal_records):
    dg = rq.get('%s/ltm/data-group/%s/%s' % (url, dg_details[0], dg_details[1])).json()

    new_records = []
    for record in removal_records:
        nr = [ {'name': record}]
        new_records.extend(nr)

    current_records = dg['records']
    new_records = [x for x in current_records if x not in new_records]

    payload = {}
    payload['records'] = new_records
    rq.put('%s/ltm/data-group/%s/%s' % (url, dg_details[0], dg_details[1]), json.dumps(payload))

if __name__ == "__main__":
    import requests, json

    b = requests.session()
    b.auth = ('admin', 'admin')
    b.verify = False
    b.headers.update({'Content-Type' : 'application/json'})

    b_url_base = 'https://172.16.44.5/mgmt/tm'

    dg_details = ['internal', 'myNetworks']
    net_changes = ['3.0.0.0/8', '4.0.0.0/8']

    print "\nExisting Records for %s Data-Group:\n\t%s" % (dg_details[1], get_dg(b, b_url_base, dg_details)['records'])
    extend_dg(b, b_url_base, dg_details, net_changes)
    print "\nUpdated Records for %s Data-Group:\n\t%s" % (dg_details[1], get_dg(b, b_url_base, dg_details)['records'])
    contract_dg(b, b_url_base, dg_details, net_changes)
    print "\nUpdated Records for %s Data-Group:\n\t%s" % (dg_details[1], get_dg(b, b_url_base, dg_details)['records'])

hi, Jason

thanks so much

it is very helpful

I am almost done with it.

but I have another question:

how to sync it to file just like the tmsh command :save sys config current-partition

POST /mgmt/tm/sys/config

With json body:

{"command": "save", "partition": ["partition1", "partition2"] }

There is no current partition context for iControl REST.

All iControl REST users are administrators as of 11.6, but you can limit their methods and trees, check out the user guide for details.

hmm, but if the user only manage partition xyz, what to do? do we need to specify the exact partition in url? the user doesn't have authority to save common partition
