SpreeMultiTenant

Adds multi-tenant support to Spree. Allows completely separate Spree sites with separate admins to be run from the same installation.

Install

Gemfile:

gem 'spree', '2.1.1'
gem 'spree_auth_devise', :git => 'git://github.com/spree/spree_auth_devise.git', :branch => '2-1-stable'
gem 'spree_multi_tenant', :git => 'git://github.com/stefansenk/spree_multi_tenant.git'

$ bundle install

Generate and run migrations:

$ rake spree_multi_tenant:install:migrations
$ rake db:migrate

Creating the first tenant

Create the fist tenant and assign all existing items to it:

$ bundle exec rake spree_multi_tenant:create_tenant_and_assign domain=mydomain.com code=mydomain

Put tenant specific template, CSS and JS files here:

app/tenants/mydomain/views/
app/assets/stylesheets/tenants/mydomain.css
app/assets/javascripts/tenants/mydomain.js

Creating more tenants

Create another tenant (without anything assigned):

$ bundle exec rake spree_multi_tenant:create_tenant domain=anotherdomain.com code=anotherdomain

Or from the console:

> Spree::Tenant.create({domain: "anotherdomain.com", code: "anotherdomain"})

With other Spree plugins

Any other models that are to be tenant specific will need to have the tenant_id field and multitenant scope added.

Database migration (e.g. db/migrate/XXXXXXXXXXXXXX_add_tenant_to_some_models.rb):

class AddTenantToSomeModels < ActiveRecord::Migration
  def change
    tables = [
      "spree_pages",
      "spree_paypal_accounts",
      "spree_product_groups",
    ]
    tables.each do |table|
      add_column table, :tenant_id, :integer
      add_index table, :tenant_id
    end
  end
end

Add scope to the models (e.g. app/models/multitenant_decorator.rb):

models = [
  Spree::Page,
  Spree::PaypalAccount,
  Spree::ProductGroup,
]
models.each do |model|
  model.class_eval do
    belongs_to :tenant
    belongs_to_multitenant
  end
end

In a Raketask

Something like this:

SpreeMultiTenant.with_tenant(Spree::Tenant.find_by_code('mydomain')) do
  # Do stuff for tenant. e.g.
  puts Spree::Product.first.name
end

Testing

$ cd spree_multi_tenant
$ bundle install
$ bundle exec rake test_app
$ bundle exec rspec spec

TODO

Don't require spree_auth_devise as a depandancy.
Allow same user email address to be used on multiple sites.
Allow tenant specific Deface overrides.
Allow same parmalinks to be used on multiple sites.
Example CSS and JS files.
Should CSS and JS files be grouped under app/tenants instead of app/assets? (e.g. app/tenants/mydomain/assets/stylesheets/store.css)
Initialise preferences.
