I test my app by postman:
statuscode:500

AppUser
using System;
using System.Collections.Generic;
using API.Extensions;
namespace API.Entities
{
public class AppUser
{
public int Id { get; set; }
public string UserName { get; set; }
public byte PasswordHash { get; set; }
public byte PasswordSalt { get; set; }
public DateTime DateOfBirth { get; set; }
public string KnownAs { get; set; }

}
}
public void Update(AppUser user)
{
_context.Entry(user).State = EntityState.Modified;
}
line 67 in UserRepostory is
_context.Entry(user).State = EntityState.Modified;
Controller Put method looks like:
[HttpPut]
public async Task UpdateUser(MemberUpdateDto memberUpdateDto)
{
var claimsIdentity = User.Identity as System.Security.Claims.ClaimsIdentity;
var username = claimsIdentity.Name;
var user = await _userRepository.GetUserByUsernameAsync(username);
_mapper.Map(memberUpdateDto, user); _userRepository.Update(user); if (await _userRepository.SaveAllAsync()) return NoContent(); return BadRequest("Failed to update user"); }
Line 51 is
_userRepository.Update(user);
MemberUpdateDto:
namespace API.DTOs
{
public class MemberUpdateDto
{
public string Introduction { get; set; }
public string LookingFor { get; set; }
public string Interests { get; set; }
public string City { get; set; }
public string Country { get; set; }
}
}
Mapper:
public class AutoMapperProfiles : Profile
{
public AutoMapperProfiles()
{
CreateMap<AppUser, MemberDto>()
.ForMember(dest => dest.PhotoUrl, opt => opt.MapFrom(src =>
src.Photos.FirstOrDefault(x => x.IsMain).Url))
.ForMember(dest => dest.Age, opt => opt.MapFrom(src => src.DateOfBirth.CalculateAge()));;
CreateMap<Photo, PhotoDto>();
CreateMap<MemberUpdateDto, AppUser>();
}
}
