Using the Programmatic Python Interface to submit reference files

As an alternative to command-line and web submissions of reference files, there is a programmatic interface that allows users to perform the tasks of reference file submission using Python. It requires crds version of at least 7.3.1.

Required CRDS Account

Submitting files to CRDS requires obtaining a CRDS account authorizing you to do so. These permissions are managed by CRDS and checked automatically after your MyST identity is verified.

To obtain a CRDS account, please file a ticket with the CRDS Jira project requesting authorization so submit files.

IMPORTANT Your MyST identity is connected to your CRDS permissions via your MyST e-mail. You should specify your MyST e-mail when applying for a CRDS account.

Authenticating

To utilize the programmatic API you are required to have a CRDS account and to authenticate via MyST and auth.mast. MyST will ask you to enter your AD password unless you have already authenticated. auth.mast supports the creation and revocation of secret token values.

The string value of this token must be inserted into the environment variable MAST_API_TOKEN:

import os
os.environ['MAST_API_TOKEN'] = 'LongStringObtainedFromAuth.mast.stsciPage'

A typical auth.mast token looks something like:

1b73d91d0db55b1800847529a3b6f91e

IMPORTANT: Since CRDS now uses MyST and auth.mast to identify you, never never directly enter your AD password (MyST password) on the CRDS server or in response to a CRDS prompt.

NOTE: CRDS passwords for existing CRDS file submitters and operators are obsolete and no longer work.

API Description

To use this functionality, import the Submission class from crds:

from crds.submit import Submission

The primary object that a user interacts with is a Submission object. This can be instantiated using the following syntax:

s = Submission('jwst', 'ops')

The Submission object has several methods, not least a .help() method that gives the full information on all the fields to be filled:

s.help()

  {'N/A', 'No', 'Yes'}

compliance_verified (str)
-------------------
Verification for compliance complete (fits, json, asdf compliant,

of files that are or are not replacing old files) (yes/no)
Valid choices:
  {'False', 'True'}

old_reference_files (str, optional)
-------------------
If yes, list them here

replacing_badfiles (str)

are affected by the changes in the files

change_level (str)
------------
Degree that new files are expected to impact science results.
Valid choices:
  {'TRIVIAL', 'SEVERE', 'MODERATE'}

correctness_testing (str)

description (str)
-----------
Information about file changes and expected impacts, include
instrument and type.  Formatting note: only alphanumeric, periods,
commas, dashes, and underscores are allowed

The fields of the submission object can be filled using (key, value) assignments as is done with Python dictionaries:

s['deliverer'] = 'Scarlet Feline'
s['other_email'] = 'redcat@stsci.edu'
s['instrument'] = 'miri'

The value of s[‘instrument’] is limited to the set of valid instruments for the observatory specified in the constructor for s. If you try to set s[‘instrument’] to something other than one of these instruments, an exception will occur. Similarly, if you try to set s[‘chicken’], or some other keyword not in the set of allowed keywords, and exception will occur:

s['file_type']                  = 'DARK'
s['history_updated']            = True
s['pedigree_updated']           = True
s['keywords_checked']           = True
s['descrip_updated']            = True
s['useafter_updated']           = True
s['useafter_matches']           = True
s['compliance_verified']        = 'N/A'
s['ingest_files']               = False
s['etc_delivery']               = False
s['jwst_etc']                   = False
s['calpipe_version']            = '0.9.1'
s['replacement_files']          = False
#s['old_reference_files']       = ''
s['replacing_badfiles']         = 'N/A'
#s['jira_issue']                = ''
s['table_rows_changed']         = 'All rows'
s['modes_affected']             = 'All MIRI observations starting 2017-Jan-03'
s['correctness_testing']        = 'DARK was run on all MIRI data and verified '
#s['additional_considerations'] = ''
s['change_level']               = 'MODERATE'
s['description']                = 'Updating MIRI DARK starting 2017-Jan-03.'

The assignments that are commented out are unnecessary as the default values are empty strings. To add files to the submission, use the add_file() method:

s.add_file('miri_dark_file.fits')

You can also remove files:

s.remove_file('miri_dark_file.fits')

And finally, when the files to be submitted have been added and the fields of the Submission have been filled in, the Submission can be submitted:

result = s.submit()

This will validate the submission by making sure all of the fields that need values have them and by ensuring that there is at least 1 file to submit before performing the submission.

The return value of submit() includes error and warning counts, as well as a link to the Review/Confirm page for the submission:

result.error_count
result.warning_count
result.ready_url

The open_ready_url() function will attempt to open the Review/Confirm page in your system’s default browser:

result.open_ready_url()

Note that the page’s confirm, cancel, and force buttons will not be available unless authenticated. If they seem to be missing, try logging in with the Login button at the upper right-hand corner of the page.
