I have two tables they have a link id being table A(Initial) tableB(dependencies) however there may be dependencies.
I’d like you to just return in the dependency sequence.
function Deps(dt) {
return new Promise((resolve,reject) => {
msg_deps.find({deps: dt},function (err, dts) {
if (err) return console.error(error);
dts.forEach(function(el) {
return resolve(el)
})
})
})
}
var Result = []
msg.find(function (err, dts) {
if (err) return console.error(error);
dts.forEach(function(el) {
//Aqui coloca o primeiro resultado no novo array
Result.push(el);
// Aqui chama a função para colocar na seq. as dependencias
// Mais não consigo acrescentar para um novo array, ou nao fica na sequencia..
AddDeps(el).then(res => Result.push(res);
})
});
Dados da tabela no mongo:

The flow I’d like would be Search the messages table for id > search each one for dependency > mount results > check next one and so on...
To make a worker...
