Importing data

To import data from YAML migration files into Repository, you run the ibexa:migrations:migrate command.

The ibexa:migrations:import command automatically places migration files in the correct folder.

Alternatively, you can place the files manually in the src/Migrations/Ibexa/migrations folder or in a custom folder that you configure, and specify the file name within this folder as parameter. If you don't specify the file, all files within this directory are used.

1
php bin/console ibexa:migrations:migrate --file=my_data_export.yaml

Migrations store execution metadata in the ibexa_migrations database table. This allows incremental upgrades: the ibexa:migrations:migrate command ignores files that it had previously executed.

Migration step

A data migration step is a single operation in data migration process that combines a mode (for example: create, update, delete) and a type (for example: content, section, currency), with optional additional information depending on the specific step.

In a migration file, a step is an array item starting with the mandatory properties type and mode, for example:

1
2
3
-
    type: content
    mode: create

Then, the step is described by additional properties depending on its type and mode.

Available migrations

The following data migration step modes are available:

type create update delete
attribute ✔ ✔ ✔
attribute_group ✔ ✔ ✔
content_type ✔ ✔ ✔
content_type_group ✔ ✔ ✔
content ✔ ✔ ✔
currency ✔ ✔ ✔
customer_group ✔ ✔ ✔
language ✔
location ✔
object_state ✔
object_state_group ✔
payment_method ✔
product_availability ✔
product_price ✔
role ✔ ✔ ✔
section ✔ ✔
segment ✔ ✔ ✔
segment_group ✔ ✔ ✔
setting ✔ ✔ ✔
user ✔ ✔
user_group ✔ ✔ ✔

Repeatable steps

You can run a set of one or more similar migration steps multiple times by using the special repeatable migration type.

A repeatable migration performs the defined migration steps as many times as the iterations setting declares.

    type: repeatable
    mode: create
    iterations: 5
    steps:

Tip

You can use repeatable migration steps, for example, to quickly generate large numbers of Content items for testing purposes.

You can vary the operations using the iteration counter.

For example, to create five Folders, with names ranging from "Folder 0" to "Folder 4", you can run the following migration using the iteration counter i:

 1
 2
 3
 4
 5
 6
 7
 8

10
11

    type: repeatable
    mode: create
    iterations: 5
    steps:
        -   type: content
            mode: create
            metadata:
                contentType: folder
                mainTranslation: eng-GB
            location:
                parentLocationId: 2
            fields:
                -   fieldDefIdentifier: name
                    languageCode: eng-GB
                    value: 'Folder ###SSS i SSS###'

To vary the content name, the migration above uses Symfony expression syntax.

In the example above, the expression is enclosed in ### and the repeated string SSS.

Note

Iteration counter is assigned to i by default, but you can modify it in the iteration_counter_name setting.

Generating fake data

You can also generate fake data with the help of FakerPHP.

To use it, first install Faker on your system:

1
composer require fakerphp/faker

Then, you can use faker() in expressions, for example:

1
2
3
                -   fieldDefIdentifier: short_name
                    languageCode: eng-GB
                    value: '### faker().name() ###'

This step generates Field values with fake personal names.

Expression syntax

You can use Symfony expression syntax in data migrations, like in repeatable steps, where you can use it to generate varied content in migration steps.

The expression syntax uses the following structure: ###<IDENTIFIER> <EXPRESSION> <IDENTIFIER>###

The IDENTIFIER can be any repeated string that encloses the actual expression.

Built-in functions

Built-in expression language functions that are tagged with ibexa.migrations.template.expression_language.function:

  • to_bool, to_int, to_float, to_string - convert various data types by passing them into PHP casting functions (like floatval, intval, and others).

    class: Closure
    factory: [ Closure, fromCallable ]
    arguments:
        - 'boolval'
    tags:
        -   name: 'ibexa.migrations.template.expression_language.function'
            function: to_bool

ibexa.migrations.template.faker:
    class: Closure
    factory: [ Closure, fromCallable ]
    arguments:
        - 'Faker\Factory::create'
    tags:
        -   name: 'ibexa.migrations.template.expression_language.function'
            function: faker

Service-based functions can be also added, but they must be callable, requiring either an __invoke function or a wrapping service with one.

Migration examples

The following examples show what data you can import using data migrations.

Content Types

The following example shows how to create a Content Type with two Field definitions.

The required metadata keys are: identifier, mainTranslation, contentTypeGroups and translations.

        mainTranslation: eng-GB
        contentTypeGroups:
            - Content
        translations:
            eng-GB:
                name: Blog Post
    fields:
        -   identifier: title
            type: ezstring
            required: true
            translations:
                eng-GB:
                    name: 'Title'
        -   identifier: body
            type: ezrichtext
            required: false
            translations:
                eng-GB:
                    name: 'Body'

Content items

The following example shows how to create two Content items: a folder and an article inside it.

When creating a Content item, three metadata keys are required: contentType, mainTranslation, and parentLocationId.

To use the Location ID of the folder, which is created automatically by the system, you can use a reference. In this case you assign the parent_folder_location_id reference name to the Location ID, and then use it when creating the article.

Images

The following example shows how to migrate an example-image.png located in public/var/site/storage/images/3/8/3/0/383-1-eng-GB without manually placing it in the appropriate path.

To prevent the manual addition of images to specific DFS or local locations, such as public/var/site/storage/images/ you can move image files to, for example src/Migrations/images. Adjust the migration file and configure the image field data as follows:

1
2
3
4
5
6
        -   fieldDefIdentifier: image
            languageCode: eng-GB
            value:
                alternativeText: ''
                fileName: example-image.png
                path: src/Migrations/images/example-image.png

This migration copies the image to the appropriate directory, in this case public/var/site/storage/images/3/8/3/0/254-1-eng-GB/example-image.png, enabling swift file migration regardless of storage (local, DFS).

Roles

The following example shows how to create a Role. A Role requires the identifier metadata key.

For each Policy assigned to the Role, you select the module and function, with optional Limitations.

The following example shows the creation of a Contributor Role:

            function: read
        -
            module: content
            function: create
            limitations:
                -
                    identifier: Class
                    values: [folder, article, blog_post]
                -
                    identifier: Section
                    values: [standard, media]
        -
            module: content
            function: edit
            limitations:
                -
                    identifier: Owner
                    values: ['1']

To update an existing Role, 2 policies' modes are available:

  • replace: (default) All existing policies are replaced by the ones from the migration.
  • append: Migration policies are added while already existing ones are kept.

The following example shows how to replace the policies of the existing Editor Role:

                    values: [ admin ]
        -   module: url

-
    type: segment_group
    mode: create
    name: 'Contractors'
    identifier: contractors
    references:
        -
            name: contractors_group_id
            type: segment_group_id

-
    type: segment
    mode: create
    name: 'Painter'
    identifier: painter
    group:
        identifier: contractors

When updating a segment group or segment, you can match the object to update by using its numerical ID or identifier:

1
2
3
4
5
6
-
    type: segment
    mode: update
    name: 'Painter and Finish'
    matcher:
        identifier: painter

Settings

The following example shows how you can create and update a setting stored in the database:

- type: setting
  mode: create
  group: test
  identifier: my_setting
  value:
      first: first_value
      second: second_value

- type: setting
  mode: update
  group: test
  identifier: my_setting
  value:
    first: first_value_modified

Taxonomies

The following example shows how you can create a "Car" tag in the main Taxonomy:

 1
 2
 3
 4
 5

 7
 8
 9
10
11
12
13
14

21
-   type: content
    mode: create
    metadata:
        contentType: tag
        mainTranslation: eng-GB
        alwaysAvailable: true
        section:
            identifier: taxonomy
    location:
        parentLocationRemoteId: taxonomy_tags_folder
    fields:
        -   fieldDefIdentifier: name
            languageCode: eng-GB
            value: Car
        -   fieldDefIdentifier: identifier
            languageCode: eng-GB
            value: car
        -   fieldDefIdentifier: parent
            languageCode: eng-GB
            value:
                taxonomy_entry_identifier: root

The field identifiers must match the identifiers used in the ibexa_taxonomy configuration file.

If the Content Type associated with the tags is changed, the configuration should be adjusted when creating migrations.

Note

If there are multiple taxonomies, the taxonomy field is then necessary here (line 21).

You can use the following example to assign tags to a Content (Content Type Article has an additional Field):
