Laravel Smart Relations Laravel Package

Product Decisions This Supports

• New feature surface unlocked by v1.2: polymorphic relations let a single association table point at multiple entity types. That directly enables a "unified engagement layer": comments/notes on any object, tagging across projects and documents, file attachments on any record, favorites/bookmarks, and a cross-entity activity/audit feed.
• Build vs. buy: the decision this most affects. Hand-rolling morphTo/morphMany per domain is cheap for one team and expensive across five. The package converts a repeated custom-build pattern into one reviewed dependency, so the comparison is "one dependency + migration" vs. "N squad-weeks of divergent implementations."
• Roadmap sequencing: stories previously deferred as "needs cross-entity associations" become estimable. Re-score the engagement-layer epic before committing the next quarter; this release is the dependency that was blocking it.
• Scope reduction: prefer one polymorphic association over adding a nullable commentable_id/project_id/document_id trio to a comments table. Fewer columns, fewer null checks, fewer per-entity endpoints.
• Explicit non-goals: this does not give you authorization, reporting, or lifecycle cleanup. Per-morph-type policies, cross-type analytics, and orphan reaping remain product/engineering work and should be staffed separately rather than assumed covered.
• Standardization decision: if adopted, mandate a stable morph map (aliases, not class names) at the org level. This is a cheap decision now and an expensive migration later — a PM-level call, not just an engineering one.

When to Consider This Package

Adopt when:

• Two or more entity types need the same association (comments, tags, attachments, audit entries).
• The team is on a Laravel version this release supports and is comfortable with Eloquent conventions.
• You want one schema and one query pattern instead of per-squad pivot tables.
• You can absorb the operational tradeoffs below and have an owner for them.

Look elsewhere when:

• Only one entity type is involved — polymorphic columns are pure overhead versus a plain foreign key.
• Reporting/BI or compliance requires database-enforced referential integrity, cascading deletes, or schema-strict immutable records. Polymorphic columns cannot carry real foreign keys; orphan cleanup becomes an application concern (scheduled jobs, soft-delete policy).
• Query volume is high and access patterns are cross-type scans — index strategy and N+1 behavior need benchmarking before commitment.
• The package's support window or maintenance cadence doesn't match your Laravel upgrade path.
• Access control is the dominant requirement: authorization per polymorphic type is easy to get subtly wrong, and a stricter domain model may be safer than a generic one.

Release-specific read: v1.2 is additive — polymorphic relations support — with no stated breaking changes or deprecations, so it is a low-risk adoption point. Validate against existing relations in a spike before retrofitting current schemas.

How to Pitch It (Stakeholders)

For executives (one paragraph): We're evaluating a small Laravel dependency whose latest release adds polymorphic relations — the ability to attach one record type (comments, tags, attachments, activity) to many different objects. It's an enabler for cross-product engagement features we've repeatedly deferred, and it replaces several one-off implementations across squads with a single reviewed pattern. Cost is one dependency, one migration, and a short technical spike; the main risk is operational discipline around cleanup and indexing, not feature risk. Recommendation: approve a scoped pilot on one low-risk feature before standardizing.

For engineering (one paragraph): v1.2 adds polymorphic relation support with no breaking changes noted. Before adoption, we need a spike covering: enforced morph map aliases (locked early — they're painful to change), index strategy on *_type/*_id pairs, N+1 behavior under realistic list endpoints, orphan-record cleanup and delete/cascade policy (no DB-level FKs available), authorization per morph type via policies, and test coverage for each registered type. Success criteria: one production feature shipped on the package, with documented conventions the next squad can follow unchanged.

Ask: a one-sprint spike plus a named owner for the conventions doc; decision to standardize deferred until the pilot ships.
