Overview
The Directus node for n8n, when configured with the Resource: Field and Operation: Update, allows you to update an existing field's configuration within a specified collection in your Directus instance. This is useful for programmatically modifying metadata, schema, or type of fields without manual intervention via the Directus admin interface.
Common scenarios include:
- Changing the data type of a field (e.g., from integer to string).
- Updating the schema or meta information of a field.
- Adjusting field options as part of automated migrations or DevOps workflows.
Practical example:
You have a "status" field in your "articles" collection that needs to be changed from a string to an integer type, or you want to update its validation rules or meta description.
Properties
Name | Type | Meaning |
---|---|---|
Field | options | Unique name of the field within the selected collection. |
Collection | options | The name of the collection containing the field to update. |
JSON/RAW Parameters | boolean | If enabled, body parameters are provided as raw JSON; otherwise, use the UI fields. |
Body Parameters | json | (Shown if JSON/RAW Parameters is true) Raw JSON object specifying all properties to update. |
Update Fields | collection | (Shown if JSON/RAW Parameters is false) Key-value pairs for updating specific field settings. |
└ Meta (JSON) | json | Optional meta information for the field. |
└ Schema (JSON) | json | Optional schema definition for the field. |
└ Type | options | Data type for the field (e.g., integer, string, boolean, etc.). |
Output
- The output is a single
json
object representing the updated field as returned by the Directus API. - The structure will match the Directus field object, typically including keys such as:
field
: The field name.type
: The data type.meta
: Any meta information.schema
: Schema details.- Other field configuration properties depending on what was updated.
Example output:
{
"field": "status",
"type": "integer",
"meta": { "interface": "input", "note": "Status as integer" },
"schema": { "default_value": 0 }
}
- Binary data: This operation does not produce binary output.
Dependencies
- External Service: Requires access to a running Directus instance.
- Authentication: Needs valid Directus API credentials configured in n8n (
directusApi
credential). - Environment: No special environment variables required beyond standard n8n and Directus setup.
Troubleshooting
Common issues:
- Invalid field or collection name: Ensure both exist in your Directus instance.
- Insufficient permissions: The API user must have permission to modify fields in the target collection.
- Malformed JSON: When using "JSON/RAW Parameters," ensure the JSON is valid.
- Type conflicts: Changing a field's type may fail if existing data cannot be converted.
Error messages:
"Field not found"
: The specified field does not exist in the collection."Collection not found"
: The specified collection does not exist."Invalid payload"
: The body parameters are malformed or missing required properties."Permission denied"
: The API key/user lacks rights to update fields.
Resolution tips:
- Double-check field and collection names.
- Validate your JSON before submitting.
- Review Directus API documentation for field update constraints.
- Check user permissions in Directus.
