Issues POSTing to /api/search/iiif with trailing slashes in "id"

[donaldgray]

We have a few object Id's that contain slashes (e.g. src:AB/1). These are used as-is in some URLs. If I use this URL as the "id" for psoting to /api/search/iiif, e.g.

{
  "contexts": [
    {
      "id": "https://mysite",
      "type": "Site"
    },
  ],
  "resource": { },
  "id": "http://mysite/objects/src:AB/1",
  "thumbnail": "https://my-thumbnails/full/!600,600/0/default.jpg"
}

I get a 400 back with body:

ImproperlyConfigured at /api/search/iiif
Could not resolve URL for hyperlinked relationship using view name "iiifresource-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.

Exception Value: Could not resolve URL for hyperlinked relationship using view name "iiifresource-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.
Request information:

If I then POST the same request again I get a 400 with:

{
    "madoc_id": [
        "iiif resource with this Identifier (Madoc) already exists."
    ]
}

Also, if I GET /api/search/iiif I get the exception

ImproperlyConfigured at /api/search/iiif

Could not resolve URL for hyperlinked relationship using view name "iiifresource-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.

This is a fairly obscure one and easily avoided but thought I'd record.
