Thank you very much Markus for your reply, I will try to implement
what you said,
What about resources in AR, it seems there is a lack of edu material,
or I can not find it, do you know a place in the cloud where I can
find
good lessons,manual,articles in AR?
Didn't knew that AR can pull out Data from multiple Databases although
I have no idea how this is implemeted, I use in Global.asax something
like this
protected void Application_Start(object sender, EventArgs e)
{
Castle.ActiveRecord.Framework.IConfigurationSource source
=
System.Configuration.ConfigurationManager.GetSection("activeRecord")
as
Castle.ActiveRecord.Framework.IConfigurationSource;
Castle.ActiveRecord.ActiveRecordStarter.Initialize(typeof(Post).Assembly,
source);
//Castle.ActiveRecord.ActiveRecordStarter.CreateSchema();
}
to initialize AR. this is one database, what about the initialization
of the second Database
where is going to take place?, do I need a separate DomainModel, how
is this handled,
its very interesting... is the code below OK (for connecting to two
different Databases).
protected void Application_Start(object sender, EventArgs e)
{
//=====================First Database================================
Castle.ActiveRecord.Framework.IConfigurationSource source
=
System.Configuration.ConfigurationManager.GetSection("activeRecord")
as
Castle.ActiveRecord.Framework.IConfigurationSource;
Castle.ActiveRecord.ActiveRecordStarter.Initialize(typeof(Post).Assembly,
source);
//Castle.ActiveRecord.ActiveRecordStarter.CreateSchema();
//=====================Second Database================================
Castle.ActiveRecord.Framework.IConfigurationSource source
=
System.Configuration.ConfigurationManager.GetSection("activeRecord_2")
as
Castle.ActiveRecord.Framework.IConfigurationSource;
Castle.ActiveRecord.ActiveRecordStarter.Initialize(typeof(SomeEntityforTheSecondDatabase).Assembly,
source);
//Castle.ActiveRecord.ActiveRecordStarter.CreateSchema();
//===================end so on....
}
