Turns out setting up to use either path based or native is very un-simple. Try if necessary another time. This reverts commit c4ecdcb.

I have made all 3 scripts into Django Management Commands. |

This was never merged! |

@G-Rath I believe this can be merged. The github ignores could possibly be removed, or can be addressed separately. |

Adds management commands to resolve discrepancies between NZSL Signbank's Postgres database and Amazon S3 file storage.
Jira ticket
CC-2305 NZSL Signbank: UAT database backport
Changes
These management commands are used to report on relationships between Signbank's Postgres database and Amazon's S3 file storage, and then assist with effecting some types of repair where discrepancies exist. See documentation.
These commands only perform certain actions, other operations have to be manually commanded using AWS
clior other means, using the output from these commands as data. See documentation.Boto3python library to talk to AWS S3.The commands require, usually in the environment:
AWS_PROFILEenvironment variable set to a pre-configured profile.DATABASE_URLenvironment variable with target and credentials.The commands have some common arguments:
--helpor-h- emit a Help message showing the available arguments.--env- specifies the target environment, eg.dev,uat,production. This is used to contruct the name of the AWS S3 bucket name, eg.nzsl-signbank-media-uat. The default isuat.--pgcli- allows the user to specify a different path for the Postgres command-line client. The default is/usr/bin/psql.Commands
get-video-s3-aclsThis command produces a full report on NZSL vs S3.
It outputs as CSV, with headers.
find-fixable-s3-orphansThis command accesses the database and S3 in a similar way to
get-video-s3-acls.py.It finds S3 objects that have no corresponding NZSL Signbank database record. These are 'orphaned' S3 objects.
It then parses the name string of the object and attempts to find an NZSL Signbank record that matches it. This is not guaranteed to be correct, so the output needs human review.
It outputs what it finds as CSV with header, in a format that can be digested by the 3rd command
repair-fixable-s3-orphans.py.repair-fixable-s3-orphansThis attempts to unify NZSL Signbank records with S3 orphans, by digesting a CSV input of the same format as output by
find-fixable-orphans.py. It does this by generatingGlossVideoDjango objects where necessary, and associating them with the correctGlossDjango objects. This operation changes the database contents and so must be used with caution.
