mORMot Open Source

Thank you @zen010101
I just didn't understand about the whitelist.

Thank you, @Thomas.
I’m trying my best to read the answers carefully, but since English isn’t my native language, I don’t fully understand everything, and sometimes I even explain things poorly.
I apologize for that. I will try harder and ask fewer questions.

When I switch from TRestServerDB to TRestServerFullMemory, how do I access the database?
Do I have to abandon ORM in this case and revert to the old method of database access?

No, I don't want to keep the tables in the original TRestServer model.

I've been unable to locate a solution to prevent direct access to the ORM.
It would be convenient if the server offered a method named AllowDirectAccess. :rolleyes

Is this error a known occurrence?
What steps should be taken to rectify this error?

---Edit
I have also successfully modified the list method.

Is this the right and proper way to do this?

function TProductService.List(var AProduct: TProductParam): RawJson;
var
  Sql: RawUtf8;
begin
  Sql := 'select * from Product';
  Result := TRestServerDB(Self.Server).DB.ExecuteJson(Sql, True);
end;

How do I disable ORM for the client?
Currently, there are commands like :
http://127.0.0.1:8080/root/Product
http://127.0.0.1:8080/root/Product/1
are returning records without any filtering or validation

I think my way of categorizing units into Controller and DAC is not very suitable for Mormot.
I should choose a different structure for categorizing files in Mormot.
Do you categorize your files in a specific way?
My next question is how to implement the List method to return the list of desired records to the client?

Thanks

What is the reason for the following error?
Project TestServer.exe raised exception class EServiceException with message 'TServiceFactoryServer.Create: IProduct routing name is already used by a Product SQL table name'.

My test Project source
https://mega.nz/file/d5RTDB5A#f-mBchZj4 … a826ZtybbA

I haven't assigned the model to TRestHttpServer.Create yet, but the problem doesn't originate from there.

In the examples, I only saw connections to SQLite. What should I do for MSSQLServer?
Which units should I add?
Previously, when accessing the database,
I created a connection and then closed it after retrieving the data. (In the events related to creating and destroying the class) And apparently here, when the server is running, the connection is created and remains open until the end of the server.

In the unit 'mormot.core.variants', the unit 'mormot.core.base' is called,
which in turn calls 'variants'. However, the IDE mistakenly identifies it as 'mormot.core.variants'.
While this is indeed an IDE error (Or an unintentional setting in the IDE) , the easiest way to prevent this is to use 'system.variants' instead.

Thank you. I will try it

Thank you for your explanation.
I generally prefer to keep the ORM and API layers separate. I'm not sure if this would cause a performance decrease.
I've been busy with other things for a while, but now I'm back to learning about Mormot. I want to create methods both with and without Models on a single server, and connect to it using a client.
I hope this isn't too difficult and I'm not bothering anyone.

Thanks @edwinsn
I am determined to learn mormot2. I can use it with the help of examples, but I wanted to understand how it works. I have a lot of questions on my mind and I hope to find the answers soon.

It would be great if this forum had a "thanks" button for posts.

That's not the problem.The problem is how to do it.

APIs can generate different types of outputs.
For example:

• A method that simply returns a number as the API version.

• A simple method (like ping) that returns a simple value (for testing connectivity).

• Up to complex methods that return a record or records from a database.

• Or even files or streams.

Therefore, an API needs to be able to access all types of methods.

I've looked through the v1 documentation as much as I can, but I'm still not sure how to connect to the TRestServerFullMemory server for communication on the client side when I'm not using a model and orm.
I used TRestHttpClient and set the model parameter to nil. But I get an accessviolation error in the ServiceDefine instruction.

Thank you.
I have created a new record for the output, but the JSON output contains both the input record and the record I defined for the output. What can I do to prevent the input from being sent in the output?
Also, how can I test this with Postman?
I tried several URLs in my Postman request, but the inputs are not being received.

get : http://127.0.0.1:8080/api/Calculator.Add/?Data={N1:1,N2:2}

post : http://127.0.0.1:8080/api/Calculator.Add
body-raw : {Data={"N1":1,"N2":2}}

Thank you for your responses, friends.

I understand that there are three ways to work with mORMot:
1 - The REST ORM
2 - Methods-based services
3 - Interface-based services

I also didn't understand how to create multiple routes for my API. What I did was look for the route name in the URL in the OnRequest event and execute a function.

I also tried to use the route and router properties in the following way, but it didn't work:
fHttpServer.Rout.Get('Ping',Ping);
fHttpServer.Router.Get('Ping',Ping);
