What is the use of mongoose methods and statics?

Question

What is the use of mongoose methods and statics and how are they different from normal functions?

Can anyone explain the difference with example.

Answer 1

If i wanted to retrieve animals with hasTail i could simply change this line of code:

return this.model('Animal').find({ type: this.type }, cb);

to:

return this.model('Animal').find({ hasTail: true }, cb);

and i would not have to create a statics function.

Use method on individual documents if you want to manipulate the individual document like adding tokens etc. Use the statics approach if you want query the whole collection.
