Module: IronAdmin::Adapters::Registry

Defined in:
lib/iron_admin/adapters/registry.rb

Overview

Lazily loads and resolves adapter classes by identifier.

Adapters are loaded on demand to avoid requiring unnecessary ORM dependencies. ActiveRecord apps never load Mongoid code and vice versa.

Examples:

Resolving an adapter

IronAdmin::Adapters::Registry.resolve(:active_record)
#=> IronAdmin::Adapters::ActiveRecord

Using a custom adapter (pass the class directly to adapter_class)

self.adapter_class = MyGem::IronAdminAdapter
