587d7fb7367417b2b2512c0d	Use model.findById() to Search Your Database By _id	2

Description

When saving a document, mongodb automatically adds the field _id, and set it to a unique alphanumeric key. Searching by _id is an extremely frequent operation, so mongoose provides a dedicated method for it. Find the (only!!) person having a given _id, using Model.findById() -> Person. Use the function argument personId as search key.

Tests

tests:
  - text: Find an item by Id should succeed
    testString: 'getUserInput => $.get(getUserInput(''url'') + ''/_api/find-by-id'').then(data => { assert.equal(data.name, ''test'', ''item.name is not what expected''); assert.equal(data.age, 0, ''item.age is not what expected''); assert.deepEqual(data.favoriteFoods, [''none''], ''item.favoriteFoods is not what expected''); assert.equal(data.__v, 0, ''The item should be not previously edited''); }, xhr => { throw new Error(xhr.responseText); })'
