Given following jsons file 


{
  "data": {
    "uuid": {
      "value": "ed64784-cjjhd6",
      "patient": false
    },
    "name": {
      "value": "Name",
      "patient": false
    },

how to select the uuid value and set it as ids in the migratin definition yml file?

here is my migration yml file: I really don't know how to select the value of the uuid as ids


id: migrate_json_file
label: Migrate content from local json file
source:
  plugin: source_url
  data_fetcher_plugin: file
  data_parser_plugin: json
  urls: data/data.json

  ids:
    value:
      selector: uuid/value
      type: string
  item_selector: /data
  fields:
  - name: uuid
    label: 'uuid'
    selector: uuid

  - name: title
    label: 'title'
    selector: name


destination:
  plugin: entity:node

  process:
    type:
      plugin: default_value
      bundle: produkt

    title: name
    field_uuid: uuid

  sticky:
    plugin: default_value
    default_value: 0
    uid:
      plugin: default_value
      default_value: 0

    migration_dependencies:
      required: {}
      optional: {}

    dependencies:
      enforced:
        module:
        - migration_json_file

Thank you in advance

Sincerely

Hermann

  • It looks like you may be missing the process section in your migration yml. Should include top level source, process and destination – David Thomas Jan 3 at 23:17

The migration template should include top level source, process and destination sections

It appears in this case you are missing the process section for the field value assignment there.

  • Hey David, your answer helped me to run the migration, although this was not the answer of my question your advice helped me avoiding getting more issues. – Hermann Jan 10 at 13:50

This worked for me:

The solution for the question: based on the json structure I provided, I could fetch the ids using the following pattern:


id: migrate_json_file
label: Migrate content from local json file
source:
  plugin: source_url
  data_fetcher_plugin: file
  data_parser_plugin: json
  urls: data/data.json

  ids:
    **uuid**
      type: string

  item_selector: /data
  fields:
  - name: uuid
    label: 'uuid'
    **selector: uuid/value**

  - name: title
    label: 'title'
    **selector: name/value**


destination:
  plugin: entity:node

  process:
    type:
      plugin: default_value
      bundle: produkt

    title: name
    field_uuid: uuid

  sticky:
    plugin: default_value
    default_value: 0
    uid:
      plugin: default_value
      default_value: 0

    migration_dependencies:
      required: {}
      optional: {}

    dependencies:
      enforced:
        module:
        - migration_json_file
