fbm admin panel

Overview

A production-grade Ruby on Rails 8 administrative dashboard managing multiple AI-powered chat applications serving thousands of users. The panel implements a sophisticated multi-database, multi-tenant architecture that enables managing multiple apps and their regional variants from a unified interface.

Key capabilities include real-time analytics dashboards, algorithmic fraud detection with risk scoring, LLM testing playground, payment aggregation across 6 processors, affiliate program management, centralized logging with automated alerts, and blog content management with cross-server synchronization.

Multi-Tenant Architecture

Thread-safe tenant context switching with PostgreSQL schema-based isolation. Each tenant (app + locale combination) operates in its own schema with dynamic SET search_path routing. Session-persisted tenant selection with real-time UI switching.

Read-only database protection via abstract base class pattern - all write operations blocked at model level, with selective WritableBase exceptions for authorized content management.

# Thread-safe tenant switching with schema isolation
around_action :with_tenant_schema

def with_tenant_schema
  PodrugaBase.connection_pool.with_connection do |conn|
    conn.execute("SET search_path TO #{current_tenant.schema}")
    yield
  end
end

# Read-only protection with selective writes
class PodrugaBase < ActiveRecord::Base
  def readonly? = true
  def save(*) = raise ActiveRecord::ReadOnlyRecord
end

class BlogPost < PodrugaWritableBase  # Exception for CMS
end
