Hi,

After updating my repo to the latest master commit from synopse repo got an error on compile in mormot.net.client.pas "E2003 Undeclared identifier TJsonClient" in line 4250.

Can't find TJsonClient class in interface section, only in implementation.

Thank you for your help @ab, it's exactly what I need.

IUserController =  interface(IInvokable)
  function GetPhoto(const ID: TID): TServiceCustomAnswer;
...

TUserController = class(TInjectableObjectRest, IUserController)
  public
    function GetPhoto(const ID: TID): TServiceCustomAnswer;
...

function TUserController.GetPhoto(const ID: TID): TServiceCustomAnswer;
var
  LPhoto: TSQLRawBlob;
begin
  if Server.RetrieveBlob(TORMUser, ID, 'Photo', LPhoto) then
  begin
    result.Header := HEADER_CONTENT_TYPE+JPEG_CONTENT_TYPE;
    result.Content := LPhoto;
    result.Status := 200;
  end
  else
  begin

Got exception when returning blob:

procedure TUserController.GetPhoto(const Ctxt: TSQLRestServerURIContext; const ID: TID);
var
  blob: TSqlRawBlob;
begin
  Server.RetrieveBlob(TORMUser, ID, 'Photo', blob);
  Ctxt.ReturnBlob(blob, HTTP_PARTIALCONTENT, true, 'photo' + IntToStr(id));
end;

It seems Ctxt.Call is nil:

procedure TRestUriContext.ReturnBlob(const Blob: RawByteString;
  Status: integer; Handle304NotModified: boolean; const FileName: TFileName;
  CacheControlMaxAge: integer);
begin
  if not ExistsIniName(pointer(fCall^.OutHead), HEADER_CONTENT_TYPE_UPPER) then    <--- Exception here

Bug or feature?

Tried before with an out parameter, but response's Content-Type was 'application/json' instead of 'image/jpeg' and was refused by client:

procedure TUserController.GetPhoto(const ID: TID; out response: TSQLRawBlob);
begin
  Server.RetrieveBlob(TORMUser, ID, 'Photo', response);
end;

How to define a Content-Type for interface based method?

Thank you for your help @ab, StaticVirtualTableDirect did the trick. I'll check if there is any performance issue with bigger table.
REST layer is very handy for basic CRUD operations with entities, and I use interface-based services for more complex requests.

Which version of mORMOt do you use? : 1.8

Which database do you use? Firebird

How is the table defined?

 TSQLUser = class(TSQLRecord)
    private
      fUsername: RawUTF8;
      fHashedPassword: RawUTF8;
      fRole: TSQLUserRole;
      FLoginDate: TDateTime;
    published
      property Username: RawUTF8 index 30 read fUsername write fUsername stored AS_UNIQUE;
      property HashedPassword: RawUTF8 index 64 read fHashedPassword write fHashedPassword;
      property Role: TSQLUserRole read fRole write fRole;
      property LoginDate: TDateTime read FLoginDate write FLoginDate;
  end;

It is wieird there is "user1" then "user2" as column name: user1 and user2 are the values of Username column of the rows 1 and 2.

You were right I found the checking for OFFSET in AdaptSQLForEngineList:

 if Stmt.Offset<>0 then begin
      InternalLog('AdaptSQLForEngineList: unsupported OFFSET for [%]',
        [SQL],sllWarning);
      exit;

I use it for pagination (but for example I put only one record by request), the data returned on the first page always works, and then on the second page nothing, but response body seems to keep good values in it.
As my client is a JavaScript and it's case sensitive, the response body of the second page was not accepted by client.
Is it possible to keep column naming structure between direct engine and virtual table?

Hi,

Can't figure out why the response from RESTful server has different column names (rowid instead of ID and camel cased) when define startIndex other than 0:

Request/Response with startIndex=0:

http://localhost:8080/root/User?select=*&startIndex=0&results=1 

[{"ID":1,"USERNAME":"user1","HASHEDPASSWORD":null,"ROLE":2,"LOGINDATE":null}]

Request/Response with startIndex=1:

http://localhost:8080/root/User?select=*&startIndex=1&results=1 

[{"rowid":2,"Username":"user2","HashedPassword":null,"Role":0,"LoginDate":null}]

Is it possible to get the same format for both requests?

TInjectableObjectRest works if declared with ServiceDefine, but this way a useless root/interfacename/{method} entry points were created. I tried TInterfaceResolverInjected.RegisterGlobal so dependable classes can find and create the object, but Rest is not injected anymore in created object (Create called instead of CreateWithResolverAndRest).


TUserService.UserRepository created and TUserService.UserRepository.Server injected, but root/userrepository/{method} service's entry points declared.

TUserRepository = class(TInjectableObjectRest, IUserRepository) 
...
TUserService = class(TInjectableObject, IUserService) 
    private
      fUserRepository: IUserRepository;
    published
      property UserRepository: IUserRepository read fUserRepository write fUserRepository;  
...
    aServer.ServiceDefine(TUserRepository, [IUserRepository], sicShared);
    aServer.ServiceDefine(TUserService, [IUserService], sicShared);

TUserService.UserRepository created, but TUserService.UserRepository.Server is nil

  TInterfaceResolverInjected.RegisterGlobal(TypeInfo(IUserRepository),TUserRepository);
  aServer.ServiceDefine(TUserService, [IUserService], sicShared);

How to register a TInjectableObjectRest class with a proper auto Rest injection and avoiding a useless entry points creation?

One can override only the same ancestor method. If the method was declared with a different parameters it can be only overload or reintroduce.

How to properly declare interfaces to permit a dependency injection in interface based services?

UserService.pas

  IUserService = interface(IInvokable)
    ['{A8C05236-F397-4422-9201-E676AB82F380}']
      function Read(ID: TID; out User: TSQLUser): boolean;   
  end;

  TUserService = class(TInterfacedObject, IUserService)
    private
      fUserRepository: IUserRepository;
    public
      constructor Create(aUserRepository: IUserRepository); reintroduce;
      function Read(ID: TID; out User: TSQLUser): boolean;                              
  end;

initialization

TInterfaceFactory.RegisterInterfaces([
   TypeInfo(IUserService)
   ]);

UserRepository.pas

  IUserRepository = interface(IInvokable)
    ['{D4AF2ABB-5D53-43CA-8403-EC4A65BB76C4}']
    function Read(ID: TID; out User: TSQLUser): boolean;
  end;

  TUserRepository = class(TInterfacedObject, IUserRepository)
  private
    fRest: TSQLRest;
  public
    constructor Create(aRest: TSQLRest); reintroduce;
    function Read(ID: TID; out User: TSQLUser): boolean;
  end;

initialization

TInterfaceFactory.RegisterInterfaces([
   TypeInfo(IUserRepository)
   ]);

Main.pas

...
aServer := TSQLRestServerDB.Create(lModel, SQLITE_MEMORY_DATABASE_NAME);
aServer.ServiceDefine(TUserService, [IUserService], sicShared);
...

The reintroduced Create constructors never called and the Read function raising exception 'fRepository is nil' . Only works a manual injection: aServer.ServiceDefine(TUserService.Create(TUserRepository.Create(aServer), [IUserService]), but I think it's not the right solution.

In case of calling "/blog/blog2/default" got the default page from second controller, but in case of calling "/blog/blog2/" the request redirected to the faulty path "blog/blog2/blog/blog2//default"

I need to share a static content between controllers. When a first controller's Views contains templates like header.partial or footer.partial and I used it from another controller through {{>../header.partial}} there is problem with a static content due to relative paths (blog/sub-uri/.static instead of blog/.static/)

Hi,
Sample starting well, I can access all views, but can't get 404 page, instead got an error  "raised exception class 'Exception: ?'" and the apps stops.

Steps to reproduce:
- Start sample and open "http://localhost:8092/blog/default"
- go to the article "http://localhost:8092/blog/articleView?id=10000"
- replace article id to get 404 error ex. "http://localhost:8092/blog/articleView?id=10001"

Error comes after "raise EMVCApplication.CreateGotoError(HTTP_NOTFOUND)", same with "raise EMVCApplication.CreateGotoView..."

No issues with Delphi.

#19 Re: mORMot 1 » Manually define MVC URI » 2016-08-21 22:41:38

It seems that the MVC URI defined in TSQLModel and not in TMVCRunOnRestServer as documentation said:

result := TSQLModel.Create([TSQLBookInfo,TSQLAuthor,
    TSQLTag,TSQLArticle,TSQLComment,TSQLArticleSearch],'blog');

And it seems I can't use a host's root as MVC root, cause TSQLModel will replace an empty URI string with 'root'. (I'm confused with using 'root', cause usually root means '/' and not '/root')

Did I missed something, but why MVC root URI was defined in TSQLModel?

Thanks,

Hi,

In framework documentation said:

In order to have the BLOG content hosted in root/blog URI, you should specify the expected sub-URI when initializing your TMVCApplication:

  procedure TBlogApplication.Start(aServer: TSQLRestServer);
  begin
  ...
  fMainRunner := TMVCRunOnRestServer.Create(self,nil,'blog').
  ...

,but in sample "30 - MVC Server" there is no sub-URI definition of the hosted MVC and it works:

  ...
  fMainRunner := TMVCRunOnRestServer.Create(Self).
  ...

How it works and is it possible to use root (/) instead of root/blog (/blog)?
