Multitenant

When building multitenant applications, never let an unscoped Model.all accidentally leak data to an unintended audience.

Usage

class User < ActiveRecord::Base
  belongs_to :tenant
  belongs_to_multitenant

  validates :email, uniqueness: true                    # application-wide uniqueness
  validates :alias, uniqueness: { scope: :tenant_id }   # tenant-wide uniqueness
end

Multitenant.with_tenant current_tenant do
  # queries within this block are automatically
  # scoped to the current tenant
  User.all

  # new objects created within this block are automatically
  # assigned to the current tenant
  User.create :name => 'Bob'
end

Features

• Rails 3 compatible
• Restrict database queries to only lookup objects for the current tenant
• Auto assign newly created objects to the current tenant

Contributing

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
• Fork the project
• Start a feature/bugfix branch
• Commit and push until you are happy with your contribution
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
