Description

Recent versions of mongoose have methods to simplify documents updating. Some more advanced features (i.e. pre/post hooks, validation) behave differently with this approach, so the Classic method is still useful in many situations. findByIdAndUpdate() can be used when searching by Id.

Instructions

Find a person by Name and set the person's age to 20. Use the function parameter personName as search key. Note: You should return the updated document. To do that you need to pass the options document { new: true } as the 3rd argument to findOneAndUpdate(). By default these methods return the unmodified object.

Tests

tests:
  - text: findOneAndUpdate an item should succeed
    testString: 'getUserInput => $.post(getUserInput(''url'') + ''/_api/find-one-update'', {name:''Dorian Gray'', age: 35, favoriteFoods:[''unknown'']}).then(data => { assert.equal(data.name, ''Dorian Gray'', ''item.name is not what expected''); assert.equal(data.age, 20, ''item.age is not what expected''); assert.deepEqual(data.favoriteFoods, [''unknown''], ''item.favoriteFoods is not what expected''); assert.equal(data.__v, 0, ''findOneAndUpdate does not increment version by design !!!''); }, xhr => { throw new Error(xhr.responseText); })'
