How to work with Boolean values in MongoDB using Node.js?

Question

I am making a Boolean entry through the mongoose schema . The parameters are : username,password and admin .

The admin parameter is set as boolean and default value as "true". Now while making an entry through post request, if I skip making the admin field, then its value gets stored as true .

But if I explicitly mention it as false , then the value is not stored in the database .

Why is this happening?

Answer 1

A javascript boolean can only either be true, or false. If it isn't true then it must be false. So any boolean field stored in the database without a value must be false (since it isn't true).
