DMVCFramework 3.0.0-hydrogen

Release Date: 2018

The beginning of the 3.x series - a complete rewrite with modern architecture.

Major Features

MVCActiveRecord ORM

Introduction of the built-in ORM:

[MVCTable('customers')]
TCustomer = class(TMVCActiveRecord)
private
  [MVCTableField('id', [foPrimaryKey, foAutoGenerated])]
  FID: Integer;
  [MVCTableField('name')]
  FName: string;
public
  property ID: Integer read FID write FID;
  property Name: string read FName write FName;
end;

// CRUD operations
Customer := TCustomer.Create;
Customer.Name := 'John Doe';
Customer.Insert;  // INSERT INTO customers...

Customer.Name := 'Jane Doe';
Customer.Update;  // UPDATE customers SET...

Customer.Delete;  // DELETE FROM customers...

Attribute-Based Routing

Declarative routing with attributes:

[MVCPath('/api/customers')]
TCustomerController = class(TMVCController)
public
  [MVCPath('/($ID)')]
  [MVCHTTPMethods([httpGET])]
  procedure GetCustomer(const ID: Integer);
end;
