# Introduction
Creating a `UniversalFlatEntityFrom` that strips out all the relation
and foreignKey properties in order to replace them with
`UniversalIdentifier` suffix
This data type will be major for the workspace migration workspace
agnostic refactor
## Chore
- renamed `flat-entity.type` to `flat-entity-from.type.ts` ( more
accurate to exported module )
- create static test type over the field metadata entity on quite
complex utils as both coverage and documentation
## Example
Here's an example of a `UniversalFlatEntityFrom<FieldMetadataEntity>`
```ts
const universalFlatFieldMetadata: UniversalFlatFieldMetadata<FieldMetadataType.RELATION> = {
// Base properties (from FieldMetadataEntity, excluding relations and applicationId)
universalIdentifier: '550e8400-e29b-41d4-a716-446655440001',
applicationUniversalIdentifier: '5800681c-088e-4e2b-9fc3-bcf6e8ec2051',
type: FieldMetadataType.RELATION,
name: 'firstName',
label: 'First Name',
defaultValue: null,
description: 'The first name of the person',
icon: 'IconUser',
standardOverrides: null,
options: null,
settings: {
relationType: RelationType.ONE_TO_MANY,
},
isCustom: false,
isActive: true,
isSystem: false,
isUIReadOnly: false,
isNullable: true,
isUnique: false,
isLabelSyncedWithName: true,
morphId: null,
// Date properties cast to string
createdAt: '2024-01-15T10:30:00.000Z',
updatedAt: '2024-01-15T10:30:00.000Z',
// ManyToOne relation universal identifiers (from FieldMetadataEntity relations)
relationTargetFieldMetadataUniversalIdentifier:
'550e8400-e29b-41d4-a716-446655440012',
relationTargetObjectMetadataUniversalIdentifier:
'550e8400-e29b-41d4-a716-446655440013',
// Join column universal identifiers (foreignKey -> universalIdentifier)
objectMetadataUniversalIdentifier: '550e8400-e29b-41d4-a716-446655440010',
// OneToMany relation universal identifiers (array of related entity identifiers)
viewFieldUniversalIdentifiers: [
'550e8400-e29b-41d4-a716-446655440020',
'550e8400-e29b-41d4-a716-446655440021',
],
viewFilterUniversalIdentifiers: ['550e8400-e29b-41d4-a716-446655440030'],
kanbanAggregateOperationViewUniversalIdentifiers: [],
calendarViewUniversalIdentifiers: [],
mainGroupByFieldMetadataViewUniversalIdentifiers: [],
};
```
## Settings
Will hop on the settings typing next. Might not be dynamic but
declarative though
