Links: Fetch data

[iLLiCiTiT]

Changelog Description

Fetch links data if server does support it.

Additional review information

Data can be fetched since AYON server 1.14.2 so it is quite new feature and can't be added all the time.

Testing notes:

1. Links data are fetched with server 1.14.2 .

It seems that when running print(ayon_api.get_version_links("test", "fa03f536-1ec3-11f1-98b1-60cf848a5b16")) it always prints [] for me, even though it should be in the database?

For completeness sake - this returning an empty list is not new. It was also in older builds it seems, so is not due to this PR.

This does return something though:

query GetVersionLinks {
  project(name: "test") {
    versions(ids: "fa03f536-1ec3-11f1-98b1-60cf848a5b16"){
      edges {
        node {
          links {
            edges {
              entityId
              linkType
              data
            }
          }
        }
      }
    }
  }
}

Returning:

Ok, found it.

version_id = "fa03f536-1ec3-11f1-98b1-60cf848a5b16"
print(ayon_api.get_version_links("test", version_id, link_types=["reference"], link_direction="in"))
print(ayon_api.get_versions_links("test", [version_id], link_types=["reference"], link_direction="in"))

The latter does print the output, the first prints the empty list.
Why is it? Because apparently the - are stripped off of the id on the returned result.

defaultdict(<class 'list'>, {'fa03f5361ec311f198b160cf848a5b16': [{'linkType': 'reference', 'direction': 'in', 'id': 'fa8a7e681ec311f18c9592a342bf613b', 'description': 'reference link with input version and output version', 'entityId': 'fe3162a05b2711f099b83c0af39c4c02', 'name': None, 'author': 'bigroy', 'entityType': 'version', 'projectName': 'test'}, {'linkType': 'reference', 'direction': 'in', 'id': 'fa93a3d01ec311f18c9592a342bf613b', 'description': 'reference link with input version and output version', 'entityId': '5c575e305cc411f090013c0af39c4c02', 'name': None, 'author': 'bigroy', 'entityType': 'version', 'projectName': 'test'}, {'linkType': 'reference', 'direction': 'in', 'id': 'fa9b4df61ec311f18c9592a342bf613b', 'description': 'reference link with input version and output version', 'entityId': 'f77bf84a1d9711f1942460cf848a5b16', 'name': None, 'author': 'bigroy', 'entityType': 'version', 'projectName': 'test'}]})

As such, the value isn't in the dict and instead the default results [] is returned.

version_id = "fa03f5361ec311f198b160cf848a5b16"
print(ayon_api.get_version_links("test", version_id, link_types=["reference"], link_direction="in"))

And voila, this does print something.

version_id = "f9d4aa9e-1ec3-11f1-ae71-60cf848a5b16".replace("-", "")
print(ayon_api.get_version_links("test", version_id, link_direction="in"))

[{'author': 'bigroy',
  'data': {},
  'description': 'generative link with input version and output version',
  'direction': 'in',
  'entityId': 'fa03f5361ec311f198b160cf848a5b16',
  'entityType': 'version',
  'id': 'fa70d4861ec311f18c9592a342bf613b',
  'linkType': 'generative',
  'name': None,
  'projectName': 'test'},
 {'author': 'bigroy',
  'data': {'hero': True, 'hero_version_id': 'fe3162a05b2711f099b83c0af39c4c02'},
  'description': 'generative link with input version and output version',
  'direction': 'in',
  'entityId': '5c575e305cc411f090013c0af39c4c02',
  'entityType': 'version',

  'linkType': 'generative',
  'name': None,
  'projectName': 'test'}]

Note that data does indeed now get included.

Works. There is the caveat that with certain api calls using ids with - in them does not return any data, like described here because it seems they are stripped on the returned id. Not sure if that should be handled more gracefully?

Not sure where did you get version id with dashes?
