-- Migration: Add Multi-Tenancy Support (LMS)
|
|
-- Based on existing schema: users, courses, enrollments
|
|
|
|
-- 1. Create organizations table (Mirrors CMS structure)
|
|
CREATE TABLE organizations (
|
|
id UUID PRIMARY KEY, -- ID synced from CMS
|
|
name VARCHAR(255) NOT NULL,
|
|
created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
|
|
updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
|
|
);
|
|
|
|
-- 2. Create default organization
|
|
INSERT INTO organizations (id, name) VALUES ('00000000-0000-0000-0000-000000000001', 'Default Organization');
|
|
|
|
-- 3. Add organization_id to tables
|
|
ALTER TABLE users ADD COLUMN organization_id UUID NOT NULL DEFAULT '00000000-0000-0000-0000-000000000001';
|
|
ALTER TABLE courses ADD COLUMN organization_id UUID NOT NULL DEFAULT '00000000-0000-0000-0000-000000000001';
|
|
ALTER TABLE enrollments ADD COLUMN organization_id UUID NOT NULL DEFAULT '00000000-0000-0000-0000-000000000001';
|
|
|
|
-- 4. Add Foreign Keys
|
|
ALTER TABLE users ADD CONSTRAINT fk_user_organization FOREIGN KEY (organization_id) REFERENCES organizations(id) ON DELETE CASCADE;
|
|
ALTER TABLE courses ADD CONSTRAINT fk_course_organization FOREIGN KEY (organization_id) REFERENCES organizations(id) ON DELETE CASCADE;
|
|
ALTER TABLE enrollments ADD CONSTRAINT fk_enrollment_organization FOREIGN KEY (organization_id) REFERENCES organizations(id) ON DELETE CASCADE;
|
|
|
|
-- 5. Remove default values
|
|
ALTER TABLE users ALTER COLUMN organization_id DROP DEFAULT;
|
|
ALTER TABLE courses ALTER COLUMN organization_id DROP DEFAULT;
|
|
ALTER TABLE enrollments ALTER COLUMN organization_id DROP DEFAULT;
|
|
|
|
-- 6. Update Unique Constraints for Users
|
|
-- Drop global unique email constraint
|
|
ALTER TABLE users DROP CONSTRAINT IF EXISTS users_email_key;
|
|
|
|
-- Add composite unique index
|
|
CREATE UNIQUE INDEX users_organization_id_email_idx ON users (organization_id, lower(email)); |
