Good evening! I have the following document:
{
"_id" : ObjectId("5b21a4332a5e3333cc64a12f"),
"nome" : "João",
"sobrenome" : "Barbosa",
"cpf" : "12345678910",
"senha" : "Fabet@1010",
"viagem" : [
{
"empresa_origem" : "BRF",
"cidade_origem" : "Concórdia",
"uf_origem" : "SC",
"pais_origem" : "Brasil",
"empresa_destino" : "Santiago Foods",
"cidade_destino" : "Santiago",
"uf_destino" : "CH",
"pais_destino" : "Chile",
"peso" : "20000",
"carga" : "Queijo",
"placa_caminhao" : "MMM-9999",
"_id" : ObjectId("5b21a4332a5e3333cc64a130")
}
],
"__v" : NumberInt(0)
}
Note that there is the vaige subdocument.
In the example above, there is the registration of a user and a trip. I would like to register more trips on this same user, as follows:
{
"_id" : ObjectId("5b21a4332a5e3333cc64a12f"),
"nome" : "João",
"sobrenome" : "Barbosa",
"cpf" : "12345678910",
"senha" : "Fabet@1010",
"viagem" : [
{
"empresa_origem" : "BRF",
"cidade_origem" : "Concórdia",
"uf_origem" : "SC",
"pais_origem" : "Brasil",
"empresa_destino" : "Santiago Foods",
"cidade_destino" : "Santiago",
"uf_destino" : "CH",
"pais_destino" : "Chile",
"peso" : "20000",
"carga" : "Queijo",
"placa_caminhao" : "MMM-9999",
"_id" : ObjectId("5b21a4332a5e3333cc64a130")
},
{
"empresa_origem" : "BRF",
"cidade_origem" : "Capinzal",
"uf_origem" : "SC",
"pais_origem" : "Brasil",
"empresa_destino" : "Santiago Foods",
"cidade_destino" : "Santiago",
"uf_destino" : "CH",
"pais_destino" : "Chile",
"peso" : "22000",
"carga" : "Carne Suína",
"placa_caminhao" : "MMM-9999",
"_id" : ObjectId("5b21a4332a5e3333cc64a131")
}
],
"__v" : NumberInt(0)
}
Is it possible? How can I do this using Mongoose? I know that I should use the _id of the "João" user as a parameter.
Hello Fred, I was wondering how you generate this _ID of each item within the 'trip', or how you assembled this model/schema
– Odirlei Borgert
@Odirleiborgert _id is an automatically generated attribute. See this guide on the site of Mongoose. Right at the beginning has an example of a schema with a subdocument. Note that there is no _id key, this is because, it is generated automatically. But if you want, you can declare _id manually as well, as in this question.

found what was missing in the schema, thank you very much...
