🔴 All editor relationships disappear
With editor-generated edges, exportSqlAlchemy treats encoded handles as column names and ignores composite metadata. Both new exporters omit every actual foreign key.
Prompt for agents
Both frontend/src/erd/sqlalchemy.ts exportSqlAlchemy and frontend/src/erd/typeorm.ts exportTypeOrm must resolve relationships from the edge contract used by the editor. Single-column edges carry encoded src-/tgt- handle IDs produced by sourceColumnHandleId and targetColumnHandleId, while edge.data contains the original sourceColumns and targetColumns. Composite foreign keys carry all columns only in edge.data and intentionally have no handles. Read and validate ForeignKeyEdgeData first, or resolve handles by matching them against each node's columns as frontend/src/erd/export.ts does. Generate every column pair for composite keys and add tests using snapshotToGraph output rather than plain, non-production handle strings.

🔴 Models target nonexistent dotted tables
Snapshot names include schemas. exportSqlAlchemy stores the dotted value as one table name, and exportTypeOrm does the same.
Prompt for agents
Split each node title into schema and relation name before emitting ORM metadata. In frontend/src/erd/sqlalchemy.ts, emit the relation as __tablename__ and the schema through __table_args__. In frontend/src/erd/typeorm.ts, emit separate name and schema Entity options. Use the same split consistently in foreign-key targets. Add coverage built from snapshotToGraph, whose titles are always schema-qualified for introspected PostgreSQL tables.

🔴 TypeORM columns lose database types
For every ordinary column, exportTypeOrm emits @Column() without its PostgreSQL type. UUID, text, bigint, decimal, and sized strings become TypeORM defaults.
Prompt for agents
Preserve database type metadata in frontend/src/erd/typeorm.ts rather than relying on reflected TypeScript types. Parse supported PostgreSQL type names, lengths, precision, scale, array status, and generated-column semantics into explicit TypeORM decorator options. PrimaryColumn and PrimaryGeneratedColumn need equivalent handling. Add tests that assert decorator metadata for uuid, text, bigint, numeric(p,s), varchar(n), date, timestamp, bytea, arrays, and serial variants.

🟡 Python keyword columns break exports
A column named class or from passes sanitizeFieldName unchanged. The downloaded SQLAlchemy model then fails Python parsing.
Prompt for agents
Extend SQLAlchemy field-name normalization in frontend/src/erd/sqlalchemy.ts to avoid Python keywords while preserving the original database column name in mapped_column. Ensure normalization remains unique within each model. Add tests for Python keywords and for collisions between original names that sanitize to the same identifier.

JSON 컬럼에 명시적 SQLAlchemy 타입을 생성하세요.
mapToPyType()는 JSON/JSONB를 dict | list로 변환하지만, exportSqlAlchemy()는 mapped_column()에 타입을 전달하지 않고 Base.type_annotation_map도 정의하지 않습니다. 사용자가 App.tsx의 SQLAlchemy 다운로드를 실행하면 SQLAlchemy 2.0.x가 이 union의 SQL 타입을 찾지 못해 생성 모델의 import/configuration이 실패할 수 있습니다. JSON 컬럼에는 JSON 또는 PostgreSQL JSONB를 명시하고 호환되는 Python annotation을 생성하세요.

SQLAlchemy 2.0 mapped_column derives SQL type from Mapped datetime.date datetime.time datetime annotation official documentation
💡 Result:
In SQLAlchemy 2.0, the mapped_column construct automatically derives the SQL datatype from Python type annotations used within the Mapped[] generic type [1][2]. This inference relies on a default type map that associates common Python types with their corresponding SQLAlchemy TypeEngine subclasses [1][3]. For date and time types, the default mapping is defined as follows [1][3]: - datetime.date is associated with sqlalchemy.types.Date [1][3] - datetime.datetime is associated with sqlalchemy.types.DateTime [1][3] - datetime.time is associated with sqlalchemy.types.Time [1][3] When you declare a column using Mapped[datetime.date], SQLAlchemy automatically uses the Date type [1]. If you provide an explicit type argument to mapped_column, such as mapped_column(Date,...), that explicit type takes precedence over the inferred type [1][3]. Important Considerations: 1. Naming Conflicts: When using datetime types, ensure you do not have a naming conflict with your column name and the imported date class [4]. For example, if you import date from datetime and name your attribute date, SQLAlchemy may encounter errors [4]. It is recommended to use aliases (e.g., from datetime import date as dt_date) or refer to the type using datetime.date [5][4]. 2. Customization: This type mapping is customizable. You can override the default types by defining a type_annotation_map on your DeclarativeBase class, which allows you to map specific Python types to different SQLAlchemy types (e.g., mapping int to BIGINT or datetime.datetime to TIMESTAMP(timezone=True)) [1][3]. Top results: [1][4][3]

소스 및 대상 핸들을 원래 컬럼명으로 디코드하세요. snapshotToGraph와 inferRelationships는 src-${sanitizeHandleId(column)} 및 tgt-${sanitizeHandleId(column)} 형식의 핸들을 생성하지만, exportSqlAlchemy는 접두사만 제거한 값을 원래 column_name과 비교합니다. 따라서 관계가 ForeignKey 없이 일반 컬럼으로 출력됩니다. 테스트도 src-user_id와 tgt-id를 사용하여 이 문제를 가립니다. 엣지를 처리할 때 두 핸들을 디코드하여 sourceFields와 targetFields에 원래 컬럼명을 저장하고, 해당 형식의 회귀 테스트를 추가하세요.

sanitizeClassName 결과를 고유하게 만드세요. exportSqlAlchemy는 각 node.data.title을 같은 방식으로 변환해 Python class 이름으로 출력합니다. 테이블 추가 및 편집 경로는 기존 제목과의 중복을 검사하지 않으므로 user-profile과 user profile이 함께 입력될 수 있고 둘 다 UserProfile이 됩니다. 이 경우 뒤의 클래스 선언이 앞의 모듈 바인딩을 덮어써 모델 하나에 접근할 수 없게 됩니다. 변환 후 고유 접미사를 할당하거나 생성 전에 충돌을 거부하고 보고하세요.

클래스 식별자 충돌을 처리하세요. PostgreSQL은 따옴표로 공백과 하이픈을 포함한 테이블 이름을 허용합니다. 현재 두 테이블 public.user-profile과 public.user profile은 모두 sanitizeClassName에서 PublicUserProfile이 됩니다. TypeORM 다운로드는 동일한 export class PublicUserProfile 선언을 생성하므로 TypeScript 컴파일이 실패합니다. 생성 전에 충돌을 보고하거나 클래스 식별자를 고유하게 만드세요.

In `@frontend/src/erd/typeorm.ts` around lines 104 - 106, Ensure the class
identifiers generated in the nodes loop via sanitizeClassName are unique when
different table names sanitize to the same value; detect collisions and either
report them before emitting output or append a deterministic unique suffix so
duplicate export class declarations cannot be produced.

원본 테이블 이름을 TypeScript 문자열 리터럴로 이스케이프하십시오.
node.data.title에 O'Reilly가 있으면 생성된 @Entity 코드의 문자열이 종료되어 컴파일이 실패합니다. 같은 인코더를 열 이름과 @JoinColumn 이름에도 적용하십시오. JSON.stringify와 같은 문자열 리터럴 인코더를 사용하고, 따옴표가 포함된 테이블 및 열 이름을 회귀 테스트에 추가하십시오.

TypeORM JoinColumn referencedColumnName relation decorator official documentation
💡 Result:
In TypeORM, the @JoinColumn decorator is used to define the owner side of a relation and to customize join column settings, including the referenced column name [1][2]. Key points regarding the referencedColumnName option: 1. Functionality: By default, TypeORM relations reference the primary column of the related entity [2]. The referencedColumnName option allows you to point the foreign key to a non-primary column in the target entity [2]. 2. Usage: You can pass this option as a property within an object inside @JoinColumn [1][2]: @ManyToOne(type => Category) @JoinColumn({ referencedColumnName: "name" }) category: Category; 3. Composite Keys: You can also handle composite foreign keys by passing an array of objects to @JoinColumn, where each object defines its own name and referencedColumnName [2][3]: @ManyToOne(type => Category) @JoinColumn([ { name: "category_id", referencedColumnName: "id" }, { name: "locale_id", referencedColumnName: "locale_id" } ]) category: Category; When using composite join columns, both the name and referencedColumnName properties are required for each entry [4]. If you do not specify a name, TypeORM generates one automatically based on the property name and the referenced column name [2][3].

targetHandle을 실제 대상 속성명으로 변환한 뒤 referencedColumnName에 지정하십시오.
targetColumnHandleId()는 인코딩된 핸들을 생성하므로 edge.targetHandle.slice(4)는 실제 열 이름이 아닙니다. 이 값을 그대로 referencedColumnName에 사용하면 TypeORM 엔티티 속성과 일치하지 않습니다. 핸들을 디코드한 값을 사용하여 @JoinColumn({ name: ..., referencedColumnName: ... })을 출력하십시오. referencedColumnName을 생략하면 TypeORM은 대상 기본 키를 사용하므로, 기본 키가 아닌 대상 열 관계를 테스트하십시오.

복수 FK에 고유한 역관계 속성 이름을 생성하십시오.
같은 Posts 모델이 Users 모델을 두 번 참조하면 두 역관계가 모두 posts가 됩니다. 생성된 클래스에는 중복 속성이 생겨 TypeScript 컴파일이 실패합니다. inc.sourceField를 이름에 포함하고, created_by_id 및 updated_by_id 관계를 함께 테스트하십시오.

Buyer scope
Add TypeORM and SQLAlchemy exports to the existing ERD export surface. The product value is only valid if generated artifacts preserve the editor's real PostgreSQL identity/FK/type contracts and remain safe to import; a download button that emits syntactically valid-looking but semantically wrong or injectable code is not complete.
Fresh exact state
main@8dc746920c12988f082e914879d95e13c9693535a929c42716bf1caf1dd68af798b65ba9a07ddb03Fresh review of the generated source found multiple still-valid correctness/security findings: production
snapshotToGraphstores ordered FK columns inedge.dataand omits handles for composite FKs, while both exporters primarily decode simplistic handle strings; schema-qualified node titles are emitted as one table name; database identifiers are interpolated into executable Python/TypeScript string literals without a code-literal encoder; SQLAlchemy can emit Python-keyword attributes and keyless mapper-invalid classes; TypeORM omits PostgreSQL type metadata. These are merge blockers, not follow-up polish.RED first
frontend/src/erd/__tests__/orm-export-contract.test.tswas added before production repair. It uses the realsnapshotToGraphcontract and currently requires:Existing unit tests that manually use
src-user_id/tgt-idare insufficient production evidence because they do not reproduce the graph's compositeForeignKeyEdgeDatacontract.Required GREEN
Repair the existing branch in place: use
ForeignKeyEdgeDataas relationship truth, preserve PostgreSQL identity/type semantics, encode all code literals, handle identifier collisions and Python keywords deterministically, make SQLAlchemy generated modules mapper-valid (including keyless-table policy), and make TypeORM decorators retain database type information and composite joins. Do not copy schema comments into executable Python without a purpose-bound contract. Keep all valid review threads and the new RED fixtures.UI Delivery Gate
Keep Draft until one unchanged exact head has focused exporter GREEN, applicable frontend unit/typecheck/build/security checks, current browser/a11y evidence for modal normal/empty/disabled/download states, and all valid review threads resolved. No force update, source-neutral retrigger, self-approval, scanner suppression or gate weakening.
