I'm working with a small application just to study .NET Core and C#. I have a model called Movie and one of its fields is a byte array to store an image. I want to know how is it possible to use JsonPatchDocument to update that field.
The Movie model:
public class Movie{ [Key] [DatabaseGenerated(DatabaseGeneratedOption.Identity)] public int id_movie { get; set; } [Required] public string name_movie { get; set; } public byte[]? img_movie { get; set; } public string? desc_movie { get; set; } public int duration_movie { get; set; } public type_class_movie class_movie { get; set; } public DateTime? created_at_movie { get; set; } public DateTime? updated_at_movie { get; set; } public int id_category_movie { get; set; } [ForeignKey("id_category_movie")] public Category? Category { get; set; }}public enum type_class_movie { Siete, Trece, Diesciseis, Dieciocho }The MoviesController:
[HttpPatch("update_movie/{id_movie:int}", Name = "UpdateMovie")]public IActionResult UpdateMovie(int id_movie, [FromForm] Movie movie, IFormFile imagen){ try { if (!_mRepo.MovieExistsById(id_movie)) { var errorResponse = new { StatusCode = 400, Message = "Movie doesn't exists" }; return StatusCode(400, errorResponse); } using (var memoryStream = new MemoryStream()) { await imagen.CopyToAsync(memoryStream); movie.img_movie = memoryStream.ToArray(); } if (!_mRepo.UpdateMovie(entity)) { var errorResponse = new { StatusCode = 500, Message = "An error ocurred while processing the request" }; return StatusCode(500, errorResponse); } return StatusCode(200, new { updt_cat = entity }); } catch (Exception ex) { Console.WriteLine(ex.ToString()); var errorResponse = new { StatusCode = "Error", Message = "An error occurred while processing the request." }; return StatusCode(500, errorResponse); }}I like the way the JsonPatchDocument partial update works, but I don't know how to use it to get a partial update of a form that may include an image, any help is appreciated.
UPDATE: This is a screenshot of patchDocument values:
