getting json array inside json object

[UIysse]

Hi,

I've spent a few hours on this and I read full doc.
I store my data fine using this code

	std::ofstream foutSave("Etudes2.json");
	if (foutSave.is_open())
	{
		using json = nlohmann::json;
		auto jsonObjectsArray = json::array();
		for (auto const &o : _vecEtude)//iterate les etudes
		{
			auto jsonObjectsArrayCritInclusion = json::array();
			auto jsonObjectsArrayCritExclusion = json::array();
			json jsonEtudeNom;
			jsonEtudeNom["_nom etude"] = o._nom.toStdString();
			for (auto const &i : o._vecCritereInclusion)//iterate le vecteur des criteres d'inclusion
			{
				json jsonObject;
				jsonObject["critere inclusion"] = i._nom.toStdString();
				jsonObjectsArrayCritInclusion.push_back(jsonObject);
			}
			jsonEtudeNom["criteres inclusion"] = { jsonObjectsArrayCritInclusion };
			for (auto const &i : o._vecCritereExclusion)//iterate le vecteur des criteres d'exclusion
			{
				json jsonObject;
				jsonObject["critere exclusion"] = i._nom.toStdString();
				jsonObjectsArrayCritExclusion.push_back(jsonObject);
			}
			jsonEtudeNom["criteres exclusion"] = { jsonObjectsArrayCritExclusion };
			jsonObjectsArray.push_back(jsonEtudeNom);
		}
		foutSave << jsonObjectsArray.dump(4) << std::endl; //.dump(4) allows pretty formatting, see nlohmann/json for more information.
	}

I get a good file, such as this one :

[
    {
        "_nom etude": "etude 1",
        "criteres exclusion": [
            {
                "critere exclusion": "exclu 1"
            },
            {
                "critere exclusion": "exclu 2"
            }
        ],
        "criteres inclusion": [
            {
                "critere inclusion": "inclu 1"
            },
            {
                "critere inclusion": "inclu 2"
            }
        ]
    },
    {
        "_nom etude": "etude 2",
        "criteres exclusion": [
            {
                "critere exclusion": "exclu 2"
            }
        ],
        "criteres inclusion": [
            {
                "critere inclusion": "inclu 2"
            }
        ]
    }
]

I get an array of etude each of which contains a name, a json array of "critere exclusion" and a json array of "critere inclusion".

The problem is reading the file.
I get the first array which i iterate with for (auto& p : jsonObject), it runs okay untill

else if (it.key() == "criteres inclusion")
However even tho this condition succeds, i can't retrieve the array associated with this key.
I've tried
auto jsonArrayCritIncl = it.value();
and
auto jsonArrayCritIncl = it.value().get<json::array>();
nothing works, could you please help me ?

		using json = nlohmann::json;
		json jsonObject = json::parse(finLoad);
		for (auto& p : jsonObject)
		{
			std::string mystr;
			Etude uneEtude;
			for (auto it = p.begin(); it != p.end(); ++it)
			{
				if (it.key() == "_nom etude")
				{
					mystr = it.value().get<std::string>();
					uneEtude._nom = QString::fromStdString(mystr);
				}
				else if (it.key() == "criteres inclusion")
				{
					//
					auto jsonArrayCritIncl = it.value();
					for (auto const& k : jsonArrayCritIncl)
					{
						//Do stuff
					}
				}
                       }
                }
      }
}
