I have created a sigle app with a Schema and a Model to create a Collection and insert some Documents.
I have my todoModel.js file:
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const todoSchema = new Schema({
username: String,
todo: String,
isDone: Boolean,
hasAttachment: Boolean
});
const Todos = mongoose.model("Todo", todoSchema);
module.exports = Todos;
Then I have created a setUpController.js file with a sample of my Documents. Then I create a Model and I pass my sample of Documents and my Schema. I create a response to send tje result in JSON. Everything good here, as I get the result in json when accessing to the route.
Here is the code:
Todos.create(sampleTodos, (err, results) => {
if (!err) {
console.log("setupTodos sample CREATED!")
res.send(results);
}
else {
console.log(`Could not create the setupTodos Database sample, err: ${err}`);
}
});
My problem is that this Documents don´t get saved in the collection !! When I access to the database, nothing is there.
This is my app.js file:
mongoose.connect("mongodb://localhost:27017/nodeTodo")
.then(connection => {
app.listen(port);
})
.catch(err => {
console.log(`Could not establish Connection with err: ${err}`);
});
Could anyone help me please ?
Thank you
You can't use object directly without making an instance of it. Try creating an instance and make the respective function call of that instance.In your case, save the document after creating an instance and it works like a charm.
const newTodos = new Todos({
username: "username",
todo: "todos",
isDone: false,
hasAttachment: flase
});
const createdTodo = newTodos.save((err, todo) => {
if(err) {
throw(err);
}
else {
//do your staff
}
})after the collection is created you can use the function inserMany to insert also a single document the function receives an array of objects and automatically saves it to the given collection
example:
Pet = new mongoose.model("pet",schemas.petSchema)
Pet.insetMany([
{
//your document
}])
it will save only one hardcoded document
I hope it was helpful
