Api error during quota rule get

[ChrisV1]

Hello,  im am receiving the following error  while trying to pull quota policy rules. 

------------------------------
Traceback (most recent call last):
File "qrule.py", line 21, in <module>
quota.get(fields='*')

File "/opt/netapp/py/.venv/lib/python3.8/site-packages/netapp_ontap/resource.py", line 568, in from_dict
raise NetAppRestError(cause=exc) from None
netapp_ontap.error.NetAppRestError: Caused by ValidationError({'space': {'soft_limit': ['"-" could not be interpreted as an integer or a valid size. Valid size values are of the form \\d+[KB|MB|GB|TB|PB].You must pass either a valid size string or an integer for soft_limit.']}, 'files': {'soft_limit': ['"-" could not be interpreted as an integer or a valid size. Valid size values are of the form \\d+[KB|MB|GB|TB|PB].You must pass either a valid size string or an integer for soft_limit.'], 'hard_limit': ['"-" could not be interpreted as an integer or a valid size. Valid size values are of the form \\d+[KB|MB|GB|TB|PB].You must pass either a valid size string or an integer for hard_limit.']}})

i assume it is because of this:

"space": {
"hard_limit": 130996502528,
"soft_limit": "-"
},
"files": {
"hard_limit": "-",
"soft_limit": "-"

but the thing is that we are never setting those limits, just hard_limit and the "-" is there by default .  this is causing failures during our reports and automation process . any idea how to skip those parameters from being retrieved ? i have found a way with try and except but that is causing for qtree's to be skipped and being left out of the report/automation process . 

from netapp_ontap import HostConnection, utils

from netapp_ontap.resources import QuotaRule

from netapp_ontap.error import NetAppRestError

import json,

import pprint

import logging

logging.basicConfig(level=logging.DEBUG)

utils.LOG_ALL_API_CALLS = 1

ctrl='c01'

vserver='svm02'

filename = 'file.json'

with HostConnection(ctrl, username="", password="", verify=False) :

    lQuotas = []

    for quota in QuotaRule.get_collection():

        #try:

        quota.get(fields='*')

        lQuotas.append(quota.to_dict())

        #except NetAppRestError as exc:

        #    if exc.http_err_response:

        #        print(">>>> err found in "+str(quota))

        #continue

        #raise exc

with open(filename, 'w') as file_in:

    json.dump(lQuotas, file_in, indent = 4)

thanks in advance!

Hi Christian, this is a bug in ONTAP. If you want to skip getting these fields in the response, you can skip those fields that are causing issues by doing something like quota.get(fields="!space.soft_limit"). This will give you all fields for that quota rule except space.soft_limit. If you want to skip multiple fields, you can provide a comma separated list as a string for fields. That could look like quota.get(fields="!space, !files"). 

So you would do something like:

for quota in QuotaRule.get_collection():

    quota.get(fields="!space.soft_limit,!files.soft_limit,!files.hard_limit")

Just make sure you don't have a space in the fields string as that can cause issues with encoding the query. Let me know if this works for you.

Hi Twesha,

thanks for your reply.  i have tried escaping the fields or calling only the space.hard_limit field before opening here the thread and even that does not work and throws errors . that is because even space.hard_limit has "-" in quota rules for example on root volumes (since a volume cannot have a quota rule so by default it has a "-") as seen in the example below:

                                                                                     Soft                 Soft

                                                 User         Disk         Disk     Files    Files

Type   Target    Qtree   Mapping     Limit    Limit   Limit    Limit  Threshold

tree          ""             ""             -               -                -            -           -          -
