Multi Tenant

An introduction on the concept of multitenant can be found at:

Documentation

1. Declare mode in Config.groovy

// Multi Tenant
tenant {
	// multiTenant is the default 
	// do "grails create-dns-map" when changing tenantDomains
	// this stroes the dns/tenant mappings into the database
	resolver.request.dns.type = "db"
}

Later on you can use tenant[dot] to refer to the TenantMap domain class (see later on).

2. Declare Tenant Class

This class should be a top level class. E.g. "Organisation" hasMany "Users".

import grails.plugin.multitenant.core.groovy.compiler.MultiTenant;
@MultiTenant
class Organisation {

[...]

3. Create a TenantMap domain class

This is achieved by using the command

grails create-dns-map

This automatically creates a domain class with the name DomainTenantMap.groovy.


package tenant

/**
 * Maps domain name to tenantId
 */
class DomainTenantMap { 
	
  String domainName
  Integer mappedTenantId
  String name
 
  static constraints = {}
}

4. Build a MultiTenat environment in BootStrap.groovy

import grails.plugin.multitenant.core.util.TenantUtils
import org.codehaus.groovy.grails.commons.ConfigurationHolder
import tenant.DomainTenantMap // was created with grails create-domain-map

class BootStrap {

   def init = { servletContext ->	
 
	def domainName = ConfigurationHolder.config.grails.tenantDomain
       if  { 
          DomainTenantMap.findByName('myweb1')
       } else {
          new DomainTenantMap(  name:'myweb1',
                                domainName:domainName,
                                mappedTenantId:1).save(flush:true);
       }

Spring Security

s2-quickstart

grails s2quickstart  your.package SecUser SecRole

creates two domain classes and corresponding controllers.

Integrade domain classes

class MyDomainClass extends SecUser {

    [...]
}

BootStrap.groovy

class BootStrap {

  def dpringSecurityService

  def init = {
    
      def userRole = SecRole.findByAuthority("ROLE_USER") ?: new SecRole(authority: "ROLE_USER").save()
      def adminRole = SecRole.findByAuthority("ROLE_ADMIN") ?: new SecRole(authority: "ROLE_ADMIN").save()
      [...]
  }
  
  def users = User.list() ?: []
  if (!users) {
     def user = new User(
         [...]
         password: springSecurityService.enodePassord("myPass")
         enabled = true
     )
  }

  SecUserSecRole.create user, userRole
 
}

Annotate the controller actions

import grails.plugins.springsecurity.Secured

class DomainClassController {

   @Secured(['ROLE_USER'])
   def myAction = {
       [...]
   }

}

Create a currentUser() method in the controller

class DomainClassController {

   @Secured(['ROLE_USER'])
   def myAction = {
       def currentUser = currentuser();
       [...]

   } 
  
       [...]
   private currentUser() {
        User.get(springSecurityService.principal.id)
