RedwoodRecord

RedwoodRecord is an ORM (Object-Relational Mapping) built on top of Prisma. It may be extended in the future to wrap other database access packages.

RedwoodRecord is heavily inspired by ActiveRecord which ships with Ruby on Rails. It presents a natural interface to the underlying data in your database, without worry about the particulars of SQL syntax.

Usage

Usage documentation is available at https://cedarjs.com/docs/redwoodrecord

Package Structure

RedwoodRecord is composed of 5 classes total:

1. Core - provides core database access for a single model, enabling CRUD actions
2. Reflection - parses the Prisma data schema and determines what relations exist to other models
3. RelationProxy - provides access to related models reveales by the Reflection class
4. ValidationMixin - adds validation support, adding error messages
5. RedwoodRecord - combines the functionality of the other four classes into the standard base class that all models should extend from

There is also an errors.js file which contains all error messages that RedwoodRecord could throw.

Tasks

RedwoodRecord depends on reading the Prisma schema file to determine relations to other tables. In order to avoid the async wait when parsing the schema with Prisma's built-in function, we have a task which parses the schema file and then saves out a JSON version to the cache .redwood directory. This task also creates an index.js file in your api/src/models directory that imports the models themselves and also adds some configuration to support relations without a circular dependency. The models are then re-exported.

This task is run with:

yarn rw record init

This task needs to be run whenever you create a new model, or change your database schema in a way that would add/remove a relation to another model.

We plan to make the task run automatically, watching for changes to your schema.prisma or models directory. But for now you'll need to run it manually!
