How can I map a custom field name (e.g. "TestCaseID") to the customfield_12345 name?

[Andrew MacCormack]

Using jira-python to acccess the REST API, I can't work out how to extract the mapping of "English" names to the customer field numbers, so I can look at the testcase ID for any of the results of my query

OK, so I worked out my own answer:

from jira.client import JIRA

def import_jira_bugs:
  jira=JIRA(your_args_here)
  resp=jira.fields()
  fmap = { }
  for i in resp.json():
     field_name=i[u'name'].encode('ascii','ignore')
     field_id=i[u'id'].encode('ascii','ignore')
     fmap[field_name]=field_id
  pprint.pprint(fmap)

REST API has a mentod to retrieve all fields with its name, id etc. See https://docs.atlassian.com/jira/REST/latest/#d2e393

Thanks, I've seen that already. If I wanted to delve into manually parsing stuff from the REST API directly, I wouldn't be using jira-python: is there a way to get this info from within jira-python?
