      Introduction

      In NocoBase, Created by automatically records the user who created a record.

      It is usually generated by preset fields and is suitable for permissions, responsibility tracking, filters, and auditing. For a business owner, handler, or approver, create a separate user relation field instead.

      Use cases

      Created by fields are suitable for these business scenarios:

      • Creation responsibility tracking
      • Audit records
      • Creator-based filters
      • Permission and workflow conditions

      Create and configure

      On the collection's Configure fields page, click Add field and select Created by to create this field.

      Configure a Created by field

      SettingDescription
      Field interfaceThe field interface. Created by uses createdBy, which determines how the field is entered and displayed in pages.
      Field display nameThe name displayed for the field, such as Created by. Use a name that business users can recognize.
      Field nameThe field identifier used internally by APIs, relation fields, permissions, and workflows. It usually cannot be changed after creation. It supports only letters, numbers, and underscores, and must begin with a letter.
      Field typeThe data-layer type. Created by uses belongsTo by default.
      Default valueThe default value. When a new record has no value, NocoBase can fill this value automatically.
      Validation rulesValidation rules. Is maintained automatically and normally does not require manual validation.
      DescriptionA field description. Record the field meaning, entry requirements, data source, or maintainer.
      Note

      Field names are referenced by page blocks, permissions, workflows, and APIs after creation. Confirm the name before creating the field to avoid later configuration changes.

      Field behavior

      The default behavior of a Created by field is as follows:

      BehaviorDescription
      Default Field interfacecreatedBy.
      Default Field typebelongsTo.
      Available Field typesbelongsTo.
      Page componentDisplays a related user maintained by the system.
      FilteringSupports filtering by creator.
      SortingSupports sorting where supported by the relation mapping.
      ValidationIs maintained automatically and normally does not require manual validation.

      Edit configuration

      After creation, click Edit beside the field to edit its configuration. Edit fields to adjust how they are displayed and used in NocoBase, such as the display name, description, default value, validation rules, or field-specific settings.

      When a field comes from a synchronized main-database table, editing usually maps the database field to a NocoBase Field type and Field interface.

      SettingCan be editedDescription
      Field display nameYesChanges the name displayed in the interface without changing the field identifier.
      Field nameNoThe field identifier normally cannot be changed in the edit form after creation.
      Field interfaceConditionalMain-database fields and synchronized fields can be adjusted during field mapping. Changes affect page input, display, and validation.
      Field typeConditionalMain-database fields and synchronized fields can be adjusted during field mapping. Confirm that existing values can be used by the new type first.
      Default valueYesAdjusts the default value for new records.
      Validation rulesYesAdjusts field validation rules.
      DescriptionYesAdds the field meaning, entry requirements, data source, or maintainer.
      Note

      Changing a Field type or Field interface is more than changing a display name. It affects field storage, input components, validation rules, filters, and workflow-variable usage. When the field contains substantial existing data, confirm that its data format is compatible first.

      Delete field

      Click Delete beside a Created by field to delete it. You can also select multiple fields and delete them in the main data source.

      Deleting a Created by field created in the main database usually also deletes the actual database column and its values. For a synchronized or external-data-source field, the impact depends on the corresponding data source and field origin.

      Warning

      Deleting a field can affect page blocks, forms, filters, permissions, workflows, APIs, imports and exports, and existing data. Confirm that the field is no longer referenced by business configuration before deleting it.

      Use in pages

      Created by fields are suitable for auditing, responsibility tracing, and creator-based filtering.
