How to post model together with embedded model using Loopback.js? - loopbackjs

Question

Here is the form model schema:
{
"startTime": "",
"stopTime": "",
"id": "objectid",
"formQuestions": [
{
"type": 0,
"label": "",
"content": [
""
],
"id": "objectid"
}
]
}
relations of form.json:
"relations": {
"questions": {
"type": "embedsMany",
"model": "FormQuestion",
"option": {
"validate": true,
"autoId": true
}
}
}
If I post to http://localhost:3000/api/Forms as follow,
{
"startTime": "",
"stopTime": "",
"formQuestions": [
{
"type": 0,
"label": "a label",
"content": ["the content"]
}
]
}
it returns:
{
"startTime": "",
"stopTime": "",
"id": "54ccf7ae6159f1bc0bc6b430",
"formQuestions": []
}
But I want the embedded model formQuestion also to be inserted into the database, how can I do it? I would be grateful if anyone could help me.

Answer 1

Nobody knows, but I find the way myself.
It is because there is some bug about auto id generating with embedded document. It is useless even I set autoId to true. So if I post with manual id, it will success.
Just like this:
{
"startTime": "",
"stopTime": "",
"formQuestions": [
{
"id": 1,
"type": 0,
"label": "a label",
"content": ["the content"]
}
]
}
