Mongoid::Tenant

Simple multi tenant for mongoid models!

Nice Tenancy for Mongoid Documents

This library is a simple way to split your client data between databases. To mongo it's pretty trivial to use multiple databases. Mongoid helps too.

Supposing you have a Bike SaaS where each Shop stores:

class Shop
  include Mongoid::Document
  include Mongoid::Tenancy

  tenant_key :url
end

class Bike
  include Mongoid::Document
  include Mongoid::Tenant
end

And that's all.

Codebase is really is small. Check lib/

Helper to set the current namespace.

Shop.first.tenancy!

Helper to execute something on each tenant namespace. has_many substitute. Eg:

class Shop
   ...
   has_tenant :bikes
end

Or raw:

Shop.tenants { |tenant| puts "#{tenant} have #{Bike.count} bike(s)" }

Index creation is the only thing overwriten in Mongoid. You'll need to provide which Tenancy to scope. In our example:

TENANCY=Shop bundle exec rails db:mongoid:create_indexes

Write your logic:

def app_domain
  @domain ||= Shop.find_by(uri: /^#{request.env["SERVER_NAME"]}/)
  @domain.tenancy!
end

Mongoid.purge! won't work. It doesn't know all dbs. A good alternative:

Mongoid.default_client.with(database: db).collections.each(&:drop)

If you don't know every db try Mongoid.default_client.list_databases.
