I see that have a lot of questions very similar to mine, but I don´t see any solutions that fit with my problem.

I' am trying to create a JSON with boost library with the below structure:

{

  "event_date": "2018-06-11T09:35:48.867Z",

  "event_log": "2018-06-11 09:35:43,253 - recycler [TRACE]: Running recycler::WITHDRAW",

  "cassettes": [

      {

          "value" : "0",

          "currency": "BRL",

          "CDMType" : "WFS_CDM_TYPEREJECTCASSETTE",

          "lppPhysical" : [

              {

                  "positionName" : "BIN1A",

                  "count" : "3"

              }

          ]

      },

      {.....},{.....}

    ]

}

Below we will have the code that I have now:

boost::property_tree::ptree children, children2, child, child1, child2, child3, child4, child5, cassettes;



child1.put("value", "cash_unit->ulValues");

child2.put("currency", "std::string(cash_unit->cCurrencyID).substr(0, 3)");

child3.put("CDMType", "cash_unit->usType");



child4.put("lppPhysical.positionName", "ph_unit->lpPhysicalPositionName");

child5.put("lppPhysical.count", "cash_unit->ulCount");



cassettes.put("event_date", "2018-06-11T09:35:48.867Z");

cassettes.put("event_log", "2018-06-11 09:35:43,253 - recycler [TRACE]: Running recycler::WITHDRAW");



children.push_back(std::make_pair("", child1));

children.push_back(std::make_pair("", child2));

children.push_back(std::make_pair("", child3));



children2.push_back(std::make_pair("", child4));

children2.push_back(std::make_pair("", child5));



cassettes.add_child("cassettes", children);



write_json("C:\Temp\test.json", cassettes);`

Summarizing, I'm having difficulties to put an array of objects inside of an array of objects.

Finally found a solution to my case, it's pretty simple but was hard to find since I am not too familiar with this library.

        //LppPhysical insertion

        lppPhysicalInfo.put("positionName", ph_unit->lpPhysicalPositionName);

        lppPhysicalInfo.put("count", cash_unit->ulCount);

        lppPhysical.push_back(std::make_pair("", lppPhysicalInfo));



        //Cassettes insertions

        cassettesInfo.put("value", cash_unit->ulValues);

        cassettesInfo.put("currency", std::string(cash_unit->cCurrencyID).substr(0, 3));

        cassettesInfo.put("CDMType", cash_unit->usType);

        cassettesInfo.add_child("lppPhysical", lppPhysical.get_child(""));

        cassettes.push_back(std::make_pair("", cassettesInfo));



        //External information insertion

        arquivo.put("event_date", "DateValue");

        arquivo.put("event_log", "LogValue");

        arquivo.add_child("cassettes", cassettes);



        //Json creator

        write_json("C:\Temp\assassino.json", arquivo); 

On the lppPhysical I just make a pair with all its content and on the Cassettes' insertion I just added the lppPhysical as a child of the cassettes and that's it. Now the lppPhysical is an array of object insde the Cassettes which is also an array of objects
