Using mix of AND and OR clause in sails and waterline

Question

How can I use OR and AND clause in Sailsjs and its ORM Waterline? For example I have a table of books

| book_name |          


        

Answer 1

The following query should also work:

const books = yield Book.find().where({
  author: 'Author-1',
  or: [{
    free: true,
  }, {
    public: true,
  }],
});
