Q : Using above code snippets where I can "Create" and "Edit" the property correctly.App's UI is having many tabs and each and every tab is having "Save" button.Hence after creating the property where user can do any change again and can press the "Save" button again.The problem comes on that moment.It gives "An internal error occurred during your request!" error box when executes below line inside the "EditPropertyAsync()" method.This is the line :

input.Property.MapTo(property);

. Could you tell me why this is happening ? This is working fine when I use the "Edit" button.The problem occurs when I try to change the record after Creating it on the same screen without going to the "Edit" button.

Note : After creating the record,it returned the newly created property id back to the ui and by using that id where I decide it to be edited record.Then it executes "EditPropertyAsync()" method.That is the way I did it when user tries to use "Save" button again on the same screen without going to the Edit button. This time only it gives above mentioned error.

Note 2 : I have found out this from log file :

    Hi,

    Actually, exception is clear: You are trying to set Id to a different value on update method. But I don't know how this happen. I implemented same pattern in the application before and it's working. Can you check what is the Id coming to the EditPropertyAsync method? Check if input.Property.Id is same as property.Id As a solution, you can define a custom mapping from PropertyEditDto to Property which excludes the Id property. But this should not be needed normally. BTW, it's not needed to this code: await _propertyRepository.UpdateAsync(property); since entities are automatically saved in a UOW (<a class="postlink" href="http://www.aspnetboilerplate.com/Pages/Documents/Unit-Of-Work#DocAutoSaveChanges">http://www.aspnetboilerplate.com/Pages/ ... aveChanges</a>)

    Hi Halil,

    Thanks for the reply. Actually the ids are the same. Please see the attached image. One thing I have to note that here that is, The relationship between the "Properties" and "Addresses" tables are 1 : 1 (I have mentioned it on the image also).Is that the issue here ? If so then how can I sort out this issue ?

    If there is no other solution could you tell me how to do custom mapping as you mentioned above.Just a reference or simple example is more than enough. Thanks in advance.

    Here is the imge url : <a class="postlink" href="http://imgur.com/a/cJdei">http://imgur.com/a/cJdei</a>

    Address :

    [Table("IpAddresses")]
    public class Address : FullAuditedEntity
    {
        public const int MaxLength = 50;

        [Key, ForeignKey("Property")]
        public override int Id { get; set; }

        [Required]
        [MaxLength(MaxLength)]
        public virtual string StreetNumber { get; set; }

        [Required]
        [MaxLength(MaxLength)]
        public virtual string StreetName { get; set; }

        [ForeignKey("CityId")]
        public virtual City City { get; set; }
        public virtual int CityId { get; set; }

        [ForeignKey("StateId")]
        public virtual State State { get; set; }
        public virtual int StateId { get; set; }

        public virtual Property Property { get; set; }
    }

    Hi,

    You can check this example:

    <a class="postlink" href="https://github.com/aspnetzero/aspnet-zero/blob/master/src/MyCompanyName.AbpZeroTemplate.Application/CustomDtoMapper.cs#L29">https://github.com/aspnetzero/aspnet-ze ... per.cs#L29</a>

    Add your custom mappings to CustomDtoMapper class as in this example. In this code, I mapped User to UserDto but ignored Password property for security. Your will be something like that:

    Mapper.CreateMap<Property, PropertyEditDto>()
    .ReverseMap()
    .ForMember(property => property.Id, options => options.Ignore());

    Don't forget to remove [AutoMap(typeof(Property))] attribute from PropertyEditDto class.

    Hi Halil,

    Hi Halil,

    Thank you so much :)

    The problem was on the "AddressDto" mapping.I have done as you said and now it's working.Thanks again :)

    Mapper.CreateMap<Address, AddressDto>()
              .ReverseMap()
              .ForMember(address => address.Id, options => options.Ignore());
