I have a little probleme. I want send in my res.json in classes: postQuery.room. But it's send in classes: undefined, why?
ROUTE GET
app.get('/', async function (req, res) {
const pageSize = +req.query.pagesize;
const page = +req.query.page;
if (pageSize && page) {
postQuery = await Classe.find({}).skip(pageSize * (page - 1)).limit(pageSize);
}
const nbClasses = await Classe.count({});
res.json({ success: true, message: "Classes fetched successfully!", classes: postQuery.room, total: nbClasses });
});
postQuery return if I use in res.json => classes: postQuery
{
"success": true,
"message": "Classes fetched successfully!",
"classes": [
{
"_id": "5bfd26072b9d9c33005b58c2",
"room": "NodeJs",
"createdAt": "2018-11-27T11:09:59.077Z",
"updatedAt": "2018-11-27T11:09:59.077Z",
"__v": 0
}
],
"total": 11
}
I think you've missed that
await Classe.find(...)...
returns an array, note the square brackets in your response. What may be helpful is:
{..., classes: postQuery.map(a=>a.room), ...}
Hope this helps.
