Do you want me to also make the String ctor to v_int64 change in this PR?

Yes, it would be cool!
Also, there are some pleases where explicit casts were applied to silent warnings... those should be deleted as well.
Unfortunately, I don't remember where exactly :)

It would be great to move all classed that use buffers to v_int64. Like MemoryLabel for example.

So I guess we can make it step-by-step. Because once you move String yo int64 to silence one bunch of warnings - others will pop up :))

... just like with any refactoring :))

Hi, I have some basic questions, the most important one is: how we can create the project, is it like Django, has any command line to create a project or not? I check the website but couldn't find anything, it would be great if someone explains it to me.

oat++

@oatpp_io_twitter

Hello @pouyapanahandeh , please checkout the starter project https://github.com/oatpp/oatpp-starter

This is a basic project with hello world endpoint

All you need is install oatpp. Checkout the starter and modify it to your needs

Please let me know if you have more questions

pooya

@pouyapanahandeh

@oatpp_io_twitter thanks for your help,
For example in Django we have the following command to create a project:
django-admin startproject mysite
How we can create the project with oatpp, I checked the link but I didn't get it well. you mean we have to clone the repo and use it as a starter project or it's an example of how the project looks like in oatpp?

oat++

@oatpp_io_twitter

Yes, you are right - just clone the stater and modify it to your needs.

Currently there is no oatpp-admin like in django. But it is a good idea to have one in future

@pouyapanahandeh

Starter is just a boilerplate precreated for you to start easier

pooya

@pouyapanahandeh

now I got it, one more question, do you have any doc how to set up the web app that written in oatpp on AWS or Azure?

oat++

@oatpp_io_twitter

Yes, there is no specific env setup for clouds. You can find some info here https://oatpp.io/docs/installation/unix-linux/

Basically you have to install c++ compiler and oatpp

Build your app and its done

However there might be some additional things depending on the OS you choose

pooya

@pouyapanahandeh

I got it, Thanks a lot for your help and time

oat++

@oatpp_io_twitter

Just text me if you face any problems. It would be helpfull for the project to know all the potential issues

pooya

@pouyapanahandeh

Sure, I will

hi, anyone familiar with oatpp-consul?

oat++

@oatpp_io_twitter

Hello @ke9 what do you need a help with ?

Marco Leclerc

@ke9

hi, wondering if the deserializer in the Client class should allow unknown fields instead of not allowing them

new fields added to an API would break "older" DTO code

I'm working on adding support for sessions in the Client

Marco Leclerc

@ke9

if you want to take a look https://github.com/ke9/oatpp-consul/tree/consul_session_support

oat++

@oatpp_io_twitter

@ke9 ,

I think that you are right. It is better to have allowUnknownFields == true for better compatibility with Consul API.

hello here, is there a recommendation which async redis client can be used (or better fits into) in aot++ framework?
and a usage example would be also very helpful... Thanks in advance!

oat++

@oatpp_io_twitter

Hello @madkote ,

I don't have any direct recommendations, but there are some points to consider:

If you are using oatpp Simple API - then it should be very easy to use any Redis client, and the process of integration should be straight forward.
If you are using oatpp Async API - then things become more complicated because, in oatpp-coroutines, you have to user oatpp-coroutines based API. It also depends on what kind of Redis API you are planning to use...
- Redis Key-Value - you'll need to do additional synchronization code. All Redis read/write should be done in the separate thread, and coroutine should wait asynchronously for the result from that thread.
- Pub/Sub - should be comparably easy to implement. You publish from a separate thread. If there is a message for subscriber, you spawn new oatpp-coroutine to handle that message.

Something like that...
Please let me know if you have more questions.

RES

@madkote

@oatpp_io_twitter thx for reply.
Simple API is clear. regarding async - I would like to avoid running redis commands in threads, therfore my question if there is any recommendation for native async redis lib.
I will look around.. thx

Hello, i have a question regarding DTO's and inheritance.

I have 2 DTO's, one "Base" and one that inherits from this. As i udnerstand it, i need to pass the class name that gets inherited from to DTO_EXTENDS like this

DTO_INIT(ChildDto, BaseDto)

instead of

DTO_INIT(ChildDto, Object)

when i do this, i get runtime errors trying to access a property of the BaseDto on an instance of ChildDto

Also, maybe this has to do with the fact that the property i try to access in the BaseDto definition is itself a Dto

class HeaderDto : public oatpp::data::mapping::type::Object
{
DTO_INIT(HeaderDto, Object)

        DTO_FIELD(Int64, time);

    };

    class ResponseDto : public oatpp::data::mapping::type::Object 
    {
        DTO_INIT(ResponseDto, Object)

        DTO_FIELD(HeaderDto::ObjectWrapper, header);
    };

i try to access field "time" on ResponseDto object via field "header"

auto dto = ResponseDto::createShared();
dto->header->time = 0;
