Adding a User field to Meal entity - Mapping Problem

Jan 9, 2014 at 9:22 PM

First of all: Congratulations for this solution! I am using for study and leaning a lot. Great coding!

I have added a User field to the Meal entity, because i want to be able to query/filter Meals and Dinners by the users that have created them. And in the future I think I will place some restrictions, so that only the owner and the administrator can edit them.

So I have added this two properties bellow to the Entity and added the field in the database too:

... Meal : DelEntity
public int UserId { get; set; }
public virtual User User { get; set; }

But my problem now is: How can i add the current user id automactally? For this I am looking to the MealController and Cruder, but it is too generic, and i really don't know here is the best point to maybe break the inherance and add my own implementation.

I think I need to add something like this in some place, but Im really confused:

SomeMealInstance.UserId = HttpContext.Current.User.Identity.Id

Can someone help me?

Thank you very much!!

you could write it without the cruder to make it simpler

or you could create a mapper for the meal just like there is one for the dinner (DinnerMapper), where you would set the UserId in the MapToEntity method

Tks O.

I have created a MealMapper just like bellow, but now im having other problems related to how search data in the repo and how to save it correctly:

public class MealMapper : Mapper<Meal, MealInput>
    public override Meal MapToEntity(MealInput input, Meal e)
        var entity = base.MapToEntity(input, e);

        var list = IoC.Resolve<IDelRepo<User>>().Where(o => o.Login.Equals(HttpContext.Current.User.Identity.Name)).GetEnumerator();
        var user = list.Current;

        //entity.User = user;
        entity.UserId = user.Id;

        return entity;

I had added the following to the WindsorConfigurator:

WindsorRegistrar.Register(typeof(IMealService), typeof(MealService)); // this line was already there ;D
WindsorRegistrar.Register(typeof(IMapper<Meal, MealInput>), typeof(MealMapper));

Got this error message: "New transaction is not allowed because there are other threads running in the session."

After a lot of hours trying to understand Im came here to ask: how is the best way to search data in the repo, and how can i save the Meal with my new Complex property?

Tks again!

I was not able to use the .ToList, and I didn't know why. But with your help I figure it out.

Now I had placed the using System.Linq, and now I can use it!

Tnks O!
