Drupal 8 - 从CSV迁移多值图像字段

Question

我正在尝试使用核心的迁移模块(Migrate module)、迁移来源CSV(Migrate Source CSV)、迁移工具(Migrate Tools)和迁移加强版(Migrate Plus)，从一个CSV文件中填充一个新的Drupal 8(8.3.2)网站的内容。我能够成功地导入每个节点，并带有单张图片，但我不确定如何将多个图片迁移到节点的多值图像字段中。

我的模块目前如下所示:

id: product_data
label: Products
migration_group: product_migration
migration_tags:
  - node
  - product
source:
  plugin: csv
  path: 'public://import/products/products.full.csv'
  header_row_count: 1
  keys:
    - product_sku
  constants:
    bool_0: 0
    bool_1: 1
    uid_root: 1
    restricted_html: restricted_html
destination:
  plugin: 'entity:node'
  default_bundle: product
process:
  title: product_name
  field_sku: product_sku
  sticky: constants/bool_0
  promote: constants/bool_1
  uid: constants/uid_root
  'field_image/target_id':
      plugin: migration
      migration: product_image
      source: product_full_image
migration_dependencies:
  optional:
    - product_image
dependencies:
  enforced:
    module:
      - custom_migration

然后创建图像实体：

id: product_image
label: Images associated with a product.
migration_group: product_migration
migration_tags:
  - product
  - file
  - image
source:
  plugin: csv
  path: 'public://import/products/products.full.csv'
  header_row_count: 1
  keys:
    - product_full_image
  fields:
    product_full_image: Name of the image file associated with the program.
  constants:
    file_source_uri: public://import/products/old-images
    file_dest_uri: 'public://program/image'
destination:
  plugin: 'entity:file'
process:
  file_source:
    -
      plugin: concat
      delimiter: /
      source:
        - constants/file_source_uri
        - product_full_image
    -
      plugin: urlencode
  file_dest:
    -
      plugin: concat
      delimiter: /
      source:
        - constants/file_dest_uri
        - product_full_image
    -
      plugin: urlencode
  filename: product_full_image
  uri:
    plugin: file_copy
    source:
      - '@file_source'
      - '@file_dest'
dependencies:
  enforced:
    module:
      - custom_migration

CSV文件的格式如下：

product_sku,product_name,product_full_image
C242,couch,Blue Couch,"image1.jpg,image2.jpg"
C243,chair,Red Chair,image3.jpg

我尝试过使用expload和iterator插件，但是说实话，我完全不知道该怎么做。如果您有任何想法，将不胜感激。

我能够解决这个问题——希望这可以帮助其他有同样问题的人。我的最终迁移如下：

主模块：

id: product_data
label: Products
migration_group: product_migration
migration_tags:
  - node
  - product
source:
  plugin: csv
  path: 'public://import/products/products.full.csv'
  header_row_count: 1
  keys:
    - product_sku
  constants:
    bool_0: 0
    bool_1: 1
    uid_root: 1
    restricted_html: restricted_html
destination:
  plugin: 'entity:node'
  overwrite_properties:
    - field_image
  default_bundle: product
process:
  field_image:
    -
      plugin: explode
      delimiter: ;
      source: image
    -
      plugin: migration
      migration: product_image
      no_stub: true
migration_dependencies:
  optional:
    - product_image
dependencies:
  enforced:
    module:
      - custom_migration

上面提到的'products.full.csv'文件长这样：

product_sku,product_name,image
C242,Blue Couch,image1.jpg;image2.jpg;image3.jpg
C243,Red Chair,image4.jpg

为了导入和创建所有图像的实体：

id: product_image
label: Import all product images.
migration_group: product_migration
migration_tags:
  - product
  - file
  - image
source:
  plugin: csv
  path: 'public://import/products/images.csv'
  header_row_count: 1
  keys:
    - image
  fields:
    new_image: Name of the image file associated with the program.
  constants:
    file_source_uri: public://import/products/images
    file_dest_uri: 'public://program/image'
destination:
  plugin: 'entity:file'
process:
  file_source:
    -
      plugin: concat
      delimiter: /
      source:
        - constants/file_source_uri
        - new_image
    -
      plugin: urlencode
  file_dest:
    -
      plugin: concat
      delimiter: /
      source:
        - constants/file_dest_uri
        - new_image
    -
      plugin: urlencode
  filename: new_image
  uri:
    plugin: file_copy
    source:
      - '@file_source'
      - '@file_dest'
dependencies:
  enforced:
    module:
      - custom_migration

上面提到的 'images.csv' 文件只有一列，只是一个所有图像的直接列表，每行一个实体：

image
image1.jpg
image2.jpg
image3.jpg
image4.jpg
