Challenge 3

Part a - add a movie

Using addMovie() function in both movieController and movieRepository, you need to implement this functionality.

Following API endpoint will be used in this task

POST /api/movie/

The request body should be as the following example.

{
      "title": "Batman Begins",
      "year": 2005,
      "dailyRentalRate": 2.5,
      "genres": ["Action", "Adventure"],
      "imdbRating": 8.2,
      "posterUrl":
        "https://www.imdb.com/title/tt0372784/mediaviewer/rm4261716480/",
      "bannerUrl":
        "https://www.imdb.com/title/tt0372784/mediaviewer/rm4261716480/",
      "plot": "After training with his mentor, Batman begins his fight to free crime-ridden Gotham City from corruption.",
      "runtime": "2hr 20min",
      "directedBy": "Christopher Nolan",
      "starring": "Christian Bale, Michael Caine, Ken Watanabe",
      "releaseAt": "2024-10-20T00:00:00.000Z",
    }

The system cannot have two movies with same title and year. Currently this condition is not evaluated in the backend. Therefore, you need to implement getMovieByNameAndYear() function in the movieRepository to return a boolean value checking for an existing movie with same title and year.

If there is an existing movie with same title and year it should return the following response with 400 http status.

{
    "message":"Movie already exists."
}

If not new movie should be inserted and 201 status should be returned.

Part b - Update daily rental rate of a movie

For this task you need to implement the updateDailyRentalRateMovie() function in both movieController and movieRepository

Following endpoint is needed to be implemented for this task

 PATCH /api/movie/:id

In the body of the request daily rental rate should be provided as in following example.

{
  "dailyRentalRate":150
}

First you need to check if ther is a movie with given movie id. If not, it should return a message named Movie not found. If there is a movie, it should return 200 status in the response.

Part c - Add new genre

In the current application user can add the same genre multiple times. You need to implement a check for this scenario in the addGenre() functions of genreController. If the genre already exists in the database it should return Genre already exists
