Managing node-types

First and foremost, you need to create a new node-type before creating any kind of node.

If you want to know more about what a node-type is, please visit the other section of the developer documentation.

Add node-type

To add a new node type, follow these steps:

1. Create the YAML file
   In the config/node_types/ directory, create a file named after your node type in lowercase (e.g., nodetypename.yaml).

2. Follow the required structure The file must follow the correct structure and parameter types:

   # 'name' is a required string.
   name: nodeTypeName

   # 'displayName' is a required string.
   displayName: 'The node type display name for editors'

   # 'color' is an optional string.
   color: '#000000'

   # 'description' is an optional string.
   description: nodeTypeName description

   # 'visible' is an optional boolean.
   visible: true

   # 'publishable' is an optional boolean.
   publishable: false

   # 'attributable' is an optional boolean.
   attributable: true

   # 'sortingAttributesByWeight' is an optional boolean.
   sortingAttributesByWeight: false

   # 'reachable' is an optional boolean.
   reachable: true

   # 'hidingNodes' is an optional boolean.
   hidingNodes: false

   # 'hidingNonReachableNodes' is an optional boolean.
   hidingNonReachableNodes: true

   # 'fields' defines the list of fields for the node type.
   # This section will be explained below in "Adding node-type field"
   fields:
       - ...
       - ...

   # 'defaultTtl' is an optional integer. It represents the number of minutes node' responses will live in HTTP cache
   defaultTtl: 15

   # 'searchable' is an optional boolean.
   searchable: true

TIP

You can use the nodetypes:validate-files command to check if your file structure is correct.

Once validated, run the app:migrate command and verify:

1. The src/GeneratedEntity/NSNodeTypeName.php file was correctly generated.
2. The API configuration in config/api_resources/nsnodetypename.yml is correct (you can test it via /api/docs).

Delete node-type

To delete a node type, remove the associated files from the following directories:

• config/node_types/
• src/GeneratedEntity/
• config/api_resources/

You can run PHPStan to ensure no references to the deleted node-type remain in your codebase:

php -d "memory_limit=-1" vendor/bin/phpstan analyse

WARNING

Deleting a node type does not remove the nodes linked to that type in the database.
You need to create a migration (command: bin/console doctrine:migrations:generate) and choose one of the following solutions.

Soft deleting nodes

If you want to transfer nodes to another existing node type while keeping their data, use a migration like this:

public function up(Schema $schema): void
{
    $this->addSql("UPDATE nodes SET nodetype_name = 'AnotherNodeTypeName' WHERE nodetype_name = 'NodeTypeName'");
    $this->addSql("UPDATE nodes_sources SET discr = 'AnotherNodeTypeName' WHERE discr = 'NodeTypeName'");
}

public function down(Schema $schema): void
{
    // Leave empty
}

TIP

Alternatively, if you want to keep your data without transferring it to another node type, you can create a "ghost" node type (GhostNodeType) with property visible to false and has no fields, then transfer your nodes there.

Hard Deleting nodes

To completely delete all nodes (and children) associated with the node type, use a migration like this:

WARNING

This method will delete all node and also its children in cascade.

public function up(Schema $schema): void
{
    $this->addSql("DELETE FROM nodes WHERE nodetype_name = 'NodeTypeName'");
    $this->addSql("DELETE FROM nodes_sources WHERE discr = 'NodeTypeName'");
}

public function down(Schema $schema): void
{
    // Leave empty
}

Adding a node-type field

To add fields to a node type, modify the fields property in your YAML file.
For example:

fields:
    -
        # Example field with minimal requirements
        name: field_name_1
        label: Field Name
        type: string
    -
        # Example field with all possible parameters
        name: field_name_2
        label: Field Name Two
        type: markdown
        groupName: string
        placeholder: string
        description: string
        minLength: 0
        maxLength: 50
        serializationMaxDepth: 2
        universal: false
        excludeFromSearch: false
        excludedFromSerialization: false
        indexed: false
        visible: true
        expanded: false
        defaultValues: null  # depends on the type
        normalizationContext:
            groups:
                - get
                - nodes_sources_base
                - nodes_sources_default
        serializationGroups: null
        serializationExclusionExpression: null

For more details on field types and parameters, refer to nodes-type-fields.

TIP

Always validate your file with nodetypes:validate-files before running app:migrate.
This command will:

• Update your node source entity.
• Generate a migration to add your fields to node_sources database table if they do not already exist in another node type.

Removing a node-type field

To remove a field from a node type, open the YAML file in config/node_types/
and delete the corresponding field from the fields array.

Example:

Before (removing field_name_2):

fields:
    -
        name: field_name_1
        label: Field Name
        type: string
    -
        name: field_name_2
        label: Field Name Two
        type: markdown

After:

fields:
    -
        name: field_name_1
        label: Field Name
        type: string

TIP

As with adding fields, validate your file with nodetypes:validate-files and then run app:migrate.
This command will update your node source entity and generate a migration to drop the field from node_sources if it is not used by another node type.
