587d7fb7367417b2b2512c0d	Use model.findById() to Search Your Database By _id	2	false	301544

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.

Instructions

Find the (only!!) person having a given _id, using Model.findById() -> Person. Use the function argument personId as the 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); })"

  Backend challenges don't need solutions, 
  because they would need to be tested against a full working project.
