OK, for a number of reasons I'm doing a Drupal 8 - Drupal 8 migration using the JSON:API module on the source site. I've run into an issue attaching taxonomy terms to nodes. Here's as far as I've gotten :
1) I created a vocabulary called "Photo Categories"
2) I've created and run import_drupal_taxonomy_photo_categories to import the terms. This works perfectly. I have manually checked to ensure they all get in. I use the UUID as the migration's unique identifier.
3) I have a content type called Photos, it has a field called Photo Category which references the Photo Categories vocabulary.
4) From the source JSON in the relationships section I see this:
"field_photo_category": {
"data": [
{
"type": "taxonomy_term--photo_categories",
"id": "84c1e8bd-16f7-429f-b299-50fe43297d47"
},
{
"type": "taxonomy_term--photo_categories",
"id": "00931a31-d129-4c55-a962-f7ba11fed5a4"
}
],
"links": {
"self": "https:\/\/seanreiser.com\/jsonapi\/node\/photo\/1396b571-0ece-4a07-ab17-7327e030dfb5\/relationships\/field_photo_category",
"related": "https:\/\/seanreiser.com\/jsonapi\/node\/photo\/1396b571-0ece-4a07-ab17-7327e030dfb5\/field_photo_category"
}
}
5) In the source > Fields section of import_drupal_type_photo I have:
-
name: field_photo_category
label: 'Field Photo Category'
selector: /relationships/field_photo_category/data
6) In the process section I have:
field_photo_category:
plugin: iterator
source: field_photo_category
process:
plugin: migration_lookup
migration: import_drupal_taxonomy_photo_categories
source: id
As I understand it this should loop through the field_photo_category.data and do a migration lookup on each id. But nothing is getting mapped.
I have verified that the ids match the ids in the data section match the UUID from the taxonomy term JSON. I have checked the database and verfied that ids appear in migrate_map_import_drupal_taxonomy_photo_categories.soure1 and they map to the appropriate tids.
I have installed the migrate devel module and when I run the migration with --migrate-debug this is what the destination section look like:
'field_photo_category' => array (2) [
array (1) [
'source' => string (36) "84c1e8bd-16f7-429f-b299-50fe43297d47"
]
array (1) [
'source' => string (36) "00931a31-d129-4c55-a962-f7ba11fed5a4"
]
]
So, my question, what am I doing wrong? I have the rest of this part of my migration laid out and this seems to be the final obstacle.
Thanks in Advance
