My task is to create a model and database for web API and CRUD purposes, one of the model properties is the photo of a car. While hardcoding data for database migration, how to set that property as a photo and save a photo path to SQL database. Later I have to manipulate with the Postman to make CRUD and API manipulations with that photo and also the other properties of that car. What is the easiest solution? I have found some info about IFormFile and byte but not sure how to do that correctly. I am using asp.net core 2.2. Thank you!
You could try to follow steps below :
1.Add a new folder to the project and call it wwwroot
, and create images folder and Cars subfolder in wwwroot
folder.
2.Model
public class Car
{
public int Id { get; set; }
public string CarName { get; set; }
public string ImagePath { get; set; }
}
public class CarViewModel
{
public string CarName { get; set; }
public IFormFile Image { get; set; }
}
3.Controller
[Route("api/[controller]")]
[ApiController]
public class CarsController : ControllerBase
{
private readonly IHostingEnvironment _hostingEnv;
private readonly WebAPIDbContext _context;
public CarsController(WebAPIDbContext context, IHostingEnvironment hostingEnv)
{
_hostingEnv = hostingEnv;
_context = context;
}
[HttpPost]
public async Task<ActionResult> Post([FromForm] CarViewModel carVM)
{
if (carVM.Image != null)
{
var a = _hostingEnv.WebRootPath;
var fileName = Path.GetFileName(carVM.Image.FileName);
var filePath = Path.Combine(_hostingEnv.WebRootPath, "images\\Cars", fileName);
using (var fileSteam = new FileStream(filePath, FileMode.Create))
{
await carVM.Image.CopyToAsync(fileSteam);
}
Car car = new Car();
car.CarName = carVM.CarName;
car.ImagePath = filePath; //save the filePath to database ImagePath field.
_context.Add(car);
await _context.SaveChangesAsync();
return Ok();
}
else
{
return BadRequest();
}
}
}
