Description

The export delivers empty checksums as empty strings:

    {
        "file": "artifact/9c/3f67ddd806d47c09d563ef94b622cd5a1736552b2f5bfb4c71f98cebb14729",
        "size": 1859,
        "md5": "",
        "sha1": "",
        "sha224": "",
        "sha256": "9c3f67ddd806d47c09d563ef94b622cd5a1736552b2f5bfb4c71f98cebb14729",
        "sha384": "",
        "sha512": "8b53cbae3f6b504981bc44d9653bc63dd21ded38ed48a168b50d515d745df13444ec0e5bddc53ed662f767d0905571eb754e4e4daa591c33ec6850bda1fb769e"
    },

At import, this fails with an error like this one :

This is only a problem when a) you have a CharField that b) is null=True unique=True that you c) export when it's null. Django-import-export exports null CharFields as blank strings.

The only fields I can find, in pulpcore, pulp_rpm, pulp_file, and pulp_container, that are exposed to this bug, are the sha224, sha384, and sha512 fields. I think if we set them to unique=False like all the checksum fields other than sha256 already are, and always have been, we can get past this.

Another option for fixing this would be to follow the pattern from here:

https://medium.com/@bramblexu/django-allow-null-for-certain-model-filed-with-blank-and-null-b0f402eeca7e

and make the checksum-fields be 'CharNullField' instead of CharField.

Either of those options sound fine to me.

Thinking out loud: would a third option be to add a before_import_row to ArtifactResource and convert these blank strings to null for sha224, sha384, and sha512?

This one would let us address the issue without a model-fix. It will have some impact on import-speed, since we'd be inspecting each row before importing - but the cost is relatively small (a function-call and three is-empty checks). Sounds reasonable to me.
