Mongoose - Save array of strings

Question

I am trying to save an array of strings into my Database using Mongoose.

So for that, I have declared a variable of a person schema:

var newPerson = new Person ({

    tags: req.body.tags

});

The schema itself looks like:

var personSchema = new mongoose.Schema({

  tags: Array

});

For saving, refer the following command

newPerson.save(function(err) {

    //basic return of JSON

});

With the help of Postman, I send in an array in the body but when I check the database, it only displays one entry with the array as a whole, you can refer to the screenshot:

Any ideas what I have to do?

In mongoose you can pass an array of strings as follows:

var personSchema = new mongoose.Schema({

tags: [{

    type: String

}]

The Postman sends the 'array' as the string so for that you can simply verify by inspecting the kind of req.body.tags. So for that refer the following command:

console.log(typeof req.body.tags)

If the above command yields a string data type then you have to set the type of the content from Postman to JSON.
