## What's New
## What's Cooking in the Lab
### DelphiMVCFramework 3.1.1-beryllium (currently in `RC` phase)
- New! Added SQLGenerator and RQL compiler for PostgreSQL and MSSQLServer (in addition to MySQL, MariaDB, Firebird and Interbase)
- Improved! Greatly improved support for [HATEOAS](https://en.wikipedia.org/wiki/HATEOAS) in renders. Check `TRenderSampleController.GetPeople_AsObjectList_HATEOS` in `renders.dproj` sample)
- Improved! Greatly improved support for [HATEOAS](https://en.wikipedia.org/wiki/HATEOAS) in renders. Check `TRenderSampleController.GetPeople_AsObjectList_HATEOS` and all the others actions end with `HATEOS` in `renders.dproj` sample)
```delphi
//Now is really easy to add "_links" property automatically for each collection element while rendering
Render<TPerson>(People, True,
procedure(const Person: TPerson; const Dict: TMVCStringDictionary)
begin
Dict['x-ref'] := '/api/people/' + Person.ID;
Dict['x-child-ref'] := '/api/people/' + Person.ID + '/child';
end);

Render<TPerson>(People, True,
procedure(const Person: TPerson; const Links: TMVCStringDictionary)
begin
Links['x-ref'] := '/api/people/' + Person.ID;
Links['x-child-ref'] := '/api/people/' + Person.ID + '/child';
end);
//Datasets have a similar anon method to do the same thing
Render(lDM.qryCustomers, False,
procedure(const DS: TDataset; const Links: TMVCStringDictionary)
begin
Links['x-ref'] := '/api/customers/' + DS.FieldByName('cust_no').AsString;
Links['x-ref-orders'] := '/api/customers/' + DS.FieldByName('cust_no').AsString + '/orders';
end);
//Datasets have a similar anon method to do the same thing
Render(lDM.qryCustomers, False,
procedure(const DS: TDataset; const Links: TMVCStringDictionary)
begin
Links['x-ref'] := '/api/customers/' + DS.FieldByName('cust_no').AsString;
Links['x-ref-orders'] := '/api/customers/' + DS.FieldByName('cust_no').AsString + '/orders';
end);
//Single object rendering allows HATEOAS too!
Render(lPerson, False,
procedure(const AObject: TObject; const Links: TMVCStringDictionary)
begin
Links['x-self'] := '/people/' + TPerson(AObject).ID.ToString;
Links['x-self-list'] := '/people';
end);
//Single object rendering allows HATEOAS too!
Render(lPerson, False,
procedure(const AObject: TObject; const Links: TMVCStringDictionary)
begin
Links['x-self'] := '/people/' + TPerson(AObject).ID.ToString;
Links['x-self-list'] := '/people';
end);
```
```
- Better packages organization (check `packages` folder)
- New! `TMVCActiveRecord.Count` method (e.g. `TMVCActiveRecord.Count(TCustomer)` returns the number of records for the entity mapped by the class `TCustomer`)
- Change! `TMVCACtiveRecord.GetByPK<T>` raises an exception if the record is not found
