Loading openconfig json fails.

[lokmahesh]

I am trying to load a json which I got from openconfig supported devices;

import pdb import json from pprint import * import pyangbind.lib.pybindJSON as pybindJSON from pyangbind.lib.serialise import pybindJSONDecoder import binding import pyangbind.lib.xpathhelper as xpathhelper ocbind = binding.openconfig_interfaces() ph = xpathhelper.YANGPathHelper() dst_ocif = pybindJSON.load("test.json", binding, "openconfig_interfaces", path_helper=ph) print pybindJSON.dumps(dst_ocif)

Attached test.txt which is test.json I am trying to load and want to convert it to IETF format but I am getting following error.

Traceback (most recent call last): File "ietf_test1.py", line 15, in dst_ocif = pybindJSON.load("test.json", binding, "openconfig_interfaces", path_helper=ph) File "/usr/local/lib/python2.7/dist-packages/pyangbind/lib/pybindJSON.py", line 78, in load extmethods=extmethods, overwrite=overwrite) File "/usr/local/lib/python2.7/dist-packages/pyangbind/lib/pybindJSON.py", line 58, in loads path_helper=path_helper, extmethods=extmethods, overwrite=overwrite) File "/usr/local/lib/python2.7/dist-packages/pyangbind/lib/serialise.py", line 271, in load_json path_helper=path_helper, skip_unknown=skip_unknown) File "/usr/local/lib/python2.7/dist-packages/pyangbind/lib/serialise.py", line 309, in load_json obj=parent, path_helper=path_helper, skip_unknown=skip_unknown) File "/usr/local/lib/python2.7/dist-packages/pyangbind/lib/serialise.py", line 271, in load_json path_helper=path_helper, skip_unknown=skip_unknown) File "/usr/local/lib/python2.7/dist-packages/pyangbind/lib/serialise.py", line 309, in load_json obj=parent, path_helper=path_helper, skip_unknown=skip_unknown) File "/usr/local/lib/python2.7/dist-packages/pyangbind/lib/serialise.py", line 271, in load_json path_helper=path_helper, skip_unknown=skip_unknown) File "/usr/local/lib/python2.7/dist-packages/pyangbind/lib/serialise.py", line 253, in load_json "did not exist (%s)" % (key)) AttributeError: JSON object contained a key thatdid not exist (name)

Where I am creating "binding" using following:

pyang --plugindir $PYBINDPLUGIN --use-xpathhelper -p /tmp/yang/standard/ietf/RFC/ -p .. -p yang-standard-openconfig/models/vlan -o binding yang-standard-openconfig/models/interfaces/openconfig-interfaces.yang yang-standard-openconfig/models/interfaces/openconfig-if-ip.yang -f pybind

test .txt

Any help ?

I tried to debug it a bit looks like sub interface having a problem that it can not find key name in it. Here is the trace:

It's actually your json that is incorrect. In the subinterface:config you gave "name": "0"

"config": {
    "enabled": true, 
    "name": "0", 
     "description": "to_ISP-A"
}

In the model it says it's "index": "0". The error states that it doesn't know the attribute 'name'.
