# Introduction The initial motivation was that in the workspace migration create action some universal foreign key aggregators weren't correctly deleted before returned due to constant missconfiguration <img width="2300" height="972" alt="image" src="https://github.com/user-attachments/assets/9401eb02-2bb2-4e69-9c5f-9a354ff61079" /> It also meant that under the hood some optimistic behavior wasn't correctly rendered for some aggregators ## Solution Refactored the `ALL_METADATA_RELATIONS` as follows: This way we can infer the FK and transpile it to a universalFK, also the aggregators are one to one instead of one versus all available Making the only manual configuration to be defined the `foreignKey` and `inverseOneToManyProperty` ``` ┌──────────────────────────────────────┐ ┌─────────────────────────────────────────────┐ │ ALL_MANY_TO_ONE_METADATA_FOREIGN_KEY│ │ ALL_ONE_TO_MANY_METADATA_RELATIONS │ │──────────────────────────────────────│ │─────────────────────────────────────────────│ │ Derived from: Entity types │ │ Derived from: Entity types │ │ │ │ │ │ Provides: │ │ Provides: │ │ • foreignKey │ │ • metadataName │ │ │ │ • flatEntityForeignKeyAggregator │ │ Standalone low-level primitive │ │ • universalFlatEntityForeignKeyAggregator │ └──────────────┬───────────────────────┘ └──────────────┬──────────────────────────────┘ │ │ │ foreignKey type + │ inverseOneToManyProperty │ universalForeignKey derivation │ keys (type constraint) │ │ ▼ ▼ ┌───────────────────────────────────────────────────────────────┐ │ ALL_MANY_TO_ONE_METADATA_RELATIONS │ │───────────────────────────────────────────────────────────────│ │ Derived from: │ │ • Entity types (metadataName, isNullable) │ │ • ALL_MANY_TO_ONE_METADATA_FOREIGN_KEY (FK → universalFK) │ │ • ALL_ONE_TO_MANY_METADATA_RELATIONS (inverse keys) │ │ │ │ Provides: │ │ • metadataName │ │ • foreignKey (replicated from FK constant) │ │ • inverseOneToManyProperty │ │ • isNullable │ │ • universalForeignKey │ └──────────────────────────┬────────────────────────────────────┘ │ ┌──────────────────┼──────────────────┐ │ │ │ ▼ ▼ ▼ ┌───────────────────┐ ┌────────────────┐ ┌──────────────────────┐ │ Type consumers │ │ Atomic utils │ │ Optimistic utils │ │───────────────────│ │────────────────│ │──────────────────────│ │ • JoinColumn │ │ • resolve-* │ │ • add/delete flat │ │ • RelatedNames │ │ • get-* │ │ entity maps │ │ • UniversalFlat │ │ │ │ • add/delete │ │ EntityFrom │ │ │ │ universal flat │ │ │ │ │ │ entity maps │ └───────────────────┘ └────────────────┘ │ │ │ (bridge via │ │ inverseOneToMany │ │ Property → │ │ ONE_TO_MANY for │ │ aggregator lookup) │ └──────────────────────┘ ``` ### Previously ``` ┌─────────────────────────────────────────────────────────────────────┐ │ ALL_METADATA_RELATIONS │ │─────────────────────────────────────────────────────────────────────│ │ Derived from: Entity types │ │ │ │ Structure: { [metadataName]: { manyToOne: {...}, oneToMany: {...},│ │ serializedRelations?: {...} } } │ │ │ │ manyToOne provides: │ │ • metadataName │ │ • foreignKey │ │ • flatEntityForeignKeyAggregator (nullable, often wrong/null) │ │ • isNullable │ │ │ │ oneToMany provides: │ │ • metadataName │ │ │ │ Monolithic single source of truth │ └──────────────────────────┬──────────────────────────────────────────┘ │ │ manyToOne entries transformed via │ ToUniversalMetadataManyToOneRelationConfiguration │ ▼ ┌─────────────────────────────────────────────────────────────────────┐ │ ALL_UNIVERSAL_METADATA_RELATIONS │ │─────────────────────────────────────────────────────────────────────│ │ Derived from: ALL_METADATA_RELATIONS (type-level transform) │ │ │ │ Structure: { [metadataName]: { manyToOne: {...}, oneToMany: {...} │ │ } } │ │ │ │ manyToOne provides: │ │ • metadataName │ │ • foreignKey │ │ • universalForeignKey (derived: FK → replace Id → UniversalId) │ │ • universalFlatEntityForeignKeyAggregator (derived from │ │ flatEntityForeignKeyAggregator → replace Ids → UniversalIds) │ │ • isNullable │ │ │ │ oneToMany: passthrough from ALL_METADATA_RELATIONS │ │ │ │ Duplicated monolith with universal key transforms │ └──────────────────────────┬──────────────────────────────────────────┘ │ ┌──────────────────┼──────────────────────┐ │ │ │ ▼ ▼ ▼ ┌───────────────┐ ┌────────────────────┐ ┌──────────────────────┐ │ Type consumers│ │ Atomic utils │ │ Optimistic utils │ │───────────────│ │────────────────────│ │──────────────────────│ │ • JoinColumn │ │ • resolve-entity- │ │ • add/delete flat │ │ • RelatedNames│ │ relation-univ-id │ │ entity maps │ │ • Universal │ │ (ALL_METADATA_ │ │ (ALL_METADATA_ │ │ FlatEntity │ │ RELATIONS │ │ RELATIONS │ │ From │ │ .manyToOne) │ │ .manyToOne) │ │ │ │ │ │ │ │ Mixed usage │ │ • resolve-univ- │ │ • add/delete univ │ │ of both │ │ relation-ids │ │ flat entity maps │ │ constants │ │ (ALL_UNIVERSAL_ │ │ (ALL_UNIVERSAL_ │ │ │ │ METADATA_REL │ │ METADATA_REL │ │ │ │ .manyToOne) │ │ .manyToOne) │ │ │ │ │ │ │ │ │ │ • resolve-univ- │ │ universalFlatEntity │ │ │ │ update-rel-ids │ │ ForeignKeyAggregator │ │ │ │ (ALL_UNIVERSAL_ │ │ read directly from │ │ │ │ METADATA_REL │ │ the constant │ │ │ │ .manyToOne) │ │ │ │ │ │ │ │ │ │ │ │ • regex hack: │ │ │ │ │ │ foreignKey │ │ │ │ │ │ .replace(/Id$/, │ │ │ │ │ │ 'UniversalId') │ │ │ └───────────────┘ └────────────────────┘ └──────────────────────┘ ``` |

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
