In this context, Martin is a undefined variable name to the JS engine.

Thus an error.

@Aayush-2492

Got it. Thanks for the explanation!

@Alababdiy

is db->execSqlSync not commit until request finished ?

Martin Chang

@marty1885

execSqlSync runs a given SQL statement and waits for it to finish. It doesn't care about committing or not. You'll want to spawn a transaction using auto transaction db->newTransaction(commit_callback) or the coroutine counterpart.

Hey! Does anyone know how to create an array of values in json? I'm trying something like this but it isn't working.

An Tao

@an-tao

please use the append method

Vikhyath-vec

@Vikhyath-vec

So, like Json::Value::append(open_complaints); ?

An Tao

@an-tao

for your case, use open_complaints.append(std::move(complaint));

Vikhyath-vec

@Vikhyath-vec

I'm still getting this error: ‘Array’ is not a member of ‘Json::Value’

An Tao

@an-tao

Json::Value array;
for(int i=0;i<10;i++) array.append(i);

Vikhyath-vec

@Vikhyath-vec

Oh, thank you for the clarification. Also, how do we parse the JSON array? Can it be like json.get("somename", []).as<vector<some_type>>(); ?

@Vikhyath-vec

How do we add third-party flags to CMakeLists.txt generated by drogon?

An Tao

@an-tao

Oh, thank you for the clarification. Also, how do we parse the JSON array? Can it be like json.get("somename", []).as<vector<some_type>>(); ?

you could use iterator to access a array json value; for example:

for(auto &item: json["array_data"])
{
    std::cout << item.asString() <<"\n";
}

How do we add third-party flags to CMakeLists.txt generated by drogon?

Just edit the CMakeLists.txt as what you want

Vikhyath-vec

@Vikhyath-vec

for(auto &item: json["array_data"])
{
    std::cout << item.asString() <<"\n";
}

Thank you, will try this out!

How do we add third-party flags to CMakeLists.txt generated by drogon?

Just edit the CMakeLists.txt as what you want

Yes, I have tried doing that but does not work for some reason.
Specifically, I want to add the flags -lpqxx and -lpq

An Tao

@an-tao

the libpq is a depandecy of drogon and automatically added.

you could use the orm part of drogon instead of libpqxx

Vikhyath-vec

@Vikhyath-vec

the libpq is a depandecy of drogon and automatically added.

but when I run the makefile, it still gives me errors which usually come when I don't include the flags

any specific commands to just add those flags? I'm weak in cmake :(

Hey guys, there's anything is possible to work with mapper's chain interface for coro?

João Fernandes

@0rangeFox

I could do this.

CoroMapper<Users> usersMapper(app().getFastDbClient());
usersMapper.limit(1).offset(0);

for (const Users &user : co_await usersMapper.findAll()) {
}

But isn't there another way to write on one line like Mapper?

Hey everyone,
I’m a beginner to drogon framework and I’m finding it difficult to install the drogon package on Mac .

Can anyone help me how to install it using vcpkg or using any other way ?

I tried “vcpkg install drogon” but it’s showing some error at the end .

Rafał Bugajewski

@rbugajewski

@ramithKS You can try the Homebrew version.

You can install Drogon on macOS with this one command: brew install rbugajewski/drogon/drogon
I also added head to the formula, so that you can always install the latest development version with the --HEAD command line argument.

You can also use the official URL now, because the repositories were moved to the organization: brew install drogonframework/drogon/drogon (yes, that’s drogon twice)

RamithKS

@ramithKS

Now I cloned it and installed according to their official documentation but the drogon autocompletes are working only if I copy and paste the drogon file to respected project I’m working on

Is there any other way ?

Is it necessary to put that into the project folder ?

Martin Chang

@marty1885

Which file are you copying? And which IDE are you using?

In most cases, CMake should pull in all the information you need.

RamithKS

@ramithKS

I’m copying the whole drogon folder which I cloned

I’m using vs code IDE

Can anyone instruct me step by step to install drogon and other dependencies in Mac ?

RamithKS

@ramithKS

Please please . Help me with this :gf

this issue

Rafał Bugajewski

@rbugajewski

@ramithKS If you have issues installing Drogon from source, you can try the Homebrew formula, as it also compiles from source.

Regarding your VSCode issue, I’m not sure, because I don’t use that editor, but I would suspect that you would have to tell the editor project configuration where your header search paths are in order to get full completion. Otherwise the LSP-Server won’t find signatures for completion.

RamithKS

@ramithKS

Hey , the issue is not regarding the IDE .

@rbugajewski can u send me the setup using Homebrew

Martin Chang

@marty1885

@ramithKS You just run /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" to install homebrew itself. Then brew install drogonframework/drogon/drogon to install drogon.
