mysql - Multiple concurrent database connections in rails -


i have rails application used several customers. each client access trough domain, domains work same rails app:

my-client-1.mycompany.com my-client-2.mycompany.com my-client-n.mycompany.com

the application works multiple databases, 1 database per client. of databases have same structure, identical. have 1 configuration per database in database.yml:

my-client-1:  adapter:  username:  my-client-2:  adapter:  username:  ...

i need indicate app based on domain used 1 user, must change database corresponding. example if user enters through my-client-2.mycompany.com database use must my-client2.

i have done including in application_controller.rb code:

before_filter :set_db_connection    def set_db_connection      d = request.host.split('.')      current_domain = d[0]      activerecord::base.establish_connection current_domain   end

now have next 2 questions:

  1. ¿is right way solve problem?
  2. ¿what happens if 1 user processing , takes 60 seconds, , in moment user enters through other domain , change connection because of code above. affect first user buy changing connection , @ point process takes 60 secs read or write wrong database?

thanks

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
