will json parse works for JSON schema inheritance

[praveensoma]

for example i have base.json with one std::string in it.

if i include it in derive.json and convert to c++ using quicktype.

what's happening is

 class Id {
        public:
        Id() = default;
        virtual ~Id() = default;

        private:
        std::string _id;

        public:
        const std::string & get_id() const { return _id; }
        std::string & get_mutable_id() { return _id; }
        void set_id(const std::string & value) {  this->_id = value; }
    };


class Derived{
        public:
        Derived() = default;
        virtual ~Derived() = default;

        private:
        Id m_id;

        public:
        const Id & get_id() const { return m_id; }
        Id & get_mutable_id() { return m_id; }
        void set_id(const Id & value) { this->m_id = value; }

       
    };

what is the correct JSON object format for Derived class

I am not sure what you want to achieve.

[nlohmann]

What did you try? Did it work? If not, what is the error message?

[praveensoma]

terminate called after throwing an instance of 'nlohmann::detail::type_error'
[json.exception.type_error.304] cannot use at() with string

[nlohmann]

And what is the code that you executed? Can you provide a small working example?

[nlohmann]

Assuming you want to extend the person struct with your own Name member, then you have to do two things:

1. Implement similar to_json/from_json functions for Name.
2. Extend the to_json/from_json functions for person to cope with the na member.

Both can be simplified with the macros NLOHMANN_DEFINE_TYPE_INTRUSIVE and NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE that we added recently, see https://github.com/nlohmann/json#simplify-your-life-with-macros.

sorry for the trouble, mistake was in our json schema, we converted it to c++, we fixed it.

Many Thanks for your time and reply
