RavenDb JsonIgnore Attribute throws error when generating document key - ravendb

Im moving out from Guid to string (HiLo) keys which is suggested by RavenDb docs.
Some of my DomainEvents gets fired inside the constructor so the Id should be known before firing the event. When I was using Guid, I'll just create Guid.NewGuid() to generate Id. But for the HiLo provided by RavenDb, what I did was an extension method to generate keys for me and then pass to my Entity constructor as argument.
RavenDb Version: RavenDb.Client 3.0.30000
Note that this is a copy-paste code I found on the internet :)
public static class RavenDbExtensions
{
public static string GenerateIdFor<T>(this IDocumentSession session)
{
// We need the advanced session in order to ensure that the keys are generated in the correct database.
// session.Advanced.DocumentStore.DatabaseCommands is not sufficient.
var advancedSession = session.Advanced as DocumentSession;
if (advancedSession == null)
throw new InvalidOperationException();
// An entity instance is required to generate a key, but we only have a type.
// In our case, the entities don't have public constructors so we must use reflection.
var entity = Activator.CreateInstance(typeof(T), true);
// Generate an ID using the commands and conventions from the current session
return advancedSession.Conventions.GenerateDocumentKey(
advancedSession.DocumentStore.Identifier,
advancedSession.DatabaseCommands,
entity);
}
}
My controller method.
[HttpPost]
[ValidateAntiForgeryToken]
[Route("add", Name = "courses.add")]
public ActionResult Add(AddViewModel model)
{
if (!ModelState.IsValid)
{
model.Categories = DocumentSession.Query<Category>().ToList();
return View(model);
}
string courseId = DocumentSession.GenerateIdFor<Course>();
var course = Course.Create(
courseId,
model.Title,
CourseCode.FromString(model.Code),
StandardDuration.Create(model.Days, model.HoursPerDay),
model.StandardPrice,
model.CategoryId);
DocumentSession.Store(course);
return RedirectToAction("Add");
}
I have this class with JsonIgnore (Raven.Imports.Newtonsoft.Json) attribute
public class StandardDuration : ValueObject
{
private StandardDuration(int days, int hoursPerDay)
{
Days = days;
HoursPerDay = hoursPerDay;
}
public int Days { get; private set; }
public int HoursPerDay { get; private set; }
public static StandardDuration Create(int days, int hoursPerDay)
{
if (days <= 0)
throw new DomainModelException("Days should be atleast one");
if (hoursPerDay <= 0)
throw new DomainModelException("CreditHours should be greater than zero");
return new StandardDuration(days, hoursPerDay);
}
[JsonIgnore]
public int CreditHours
{
get { return HoursPerDay * Days; }
}
protected override IEnumerable<object> GetEqualityComponents()
{
yield return Days;
yield return HoursPerDay;
}
}
which throws an error
Attempt by method 'Raven.Client.Document.DocumentConvention.DefaultTypeTagName(System.Type)' to access method 'Raven.Imports.Newtonsoft.Json.Utilities.TypeExtensions.IsGenericType(System.Type)' failed.
UPDATE
I cant reproduce the error on the code above due to same issue but before showing the page.
But Im facing the same issue even on non JsonIgnore decorated classes.
public class Category : Entity
{
private Category() { }
private Category(Guid id, string name)
{
Id = id;
Name = name;
}
public string Name { get; private set; }
public static Category Create(Guid id, string name)
{
if (string.IsNullOrWhiteSpace(name))
throw new DomainModelException("Category name should not be blank or null.");
return new Category(id, name);
}
}
controller action
[HttpPost]
[Route("add", Name = "course_categories.add")]
public ActionResult Add(string name)
{
if (ModelState.IsValid)
{
var courseCategory = Category.Create(Guid.NewGuid(), name);
DocumentSession.Store(courseCategory);
AddSuccessMessage("Course Category created");
return RedirectToRoute("course_categories.add_page");
}
ModelState.AddModelError("", "An error occurred please try again.");
return View();

why it throws an exception when i tried to save a user?

This related to my previous post, even though it was original posted as this post it ran in to another problem to which it was answered. So to avoid complexity i have decided to re-post it with a confirmed single error!
i have the following Create() post method to save a user to mst_users table.
[HttpPost]
public ActionResult Create(CustomerVM custObject)
{
if ( ModelState.IsValid )
{
mst_users user = new mst_users
{
uName=custObject.User,
password=custObject.Password,
dtCreated=DateTime.UtcNow,
isLocked=false
};
db.mst_users.Add(user);
db.SaveChanges();
}
}
}
when the methods executes at db.SaveChanges() it throws the error Object is not set an instance of an object but i have initialzed all required fields for the table but it shows me a field in a view that belongs to another collection but its not part of users table here is the video
here is the user object:
here is the error:
Object reference not set to an instance of an object.

try to do something like this
mst_users user = new mst_users();
user.uName=custObject.User;
user.password=custObject.Password;
user.dtCreated=DateTime.UtcNow;
user.isLocked=false;
db.mst_users.Add(user);
db.SaveChanges();
the problem was solved, even when i tagged the db table dtUpdated as not null and assigned with getDate() i must send a date from client else throws the above error!

webapi IPrincipal and authorize

this is about security MVC4 RC and "Install-Package Microsoft.AspNet.WebApi".
I create a custom Identity : System.Security.Principal.IIdentity where i store some valuable string's and int's in the authentication cookie:
[Serializable]
public class SiteIdentity : IIdentity
{
public SiteIdentity(string name, string displayName, int userId, int siteId)
{
this.Name = name;
this.DisplayName = displayName;
this.UserId = userId;
this.SiteId = siteId;
}
public SiteIdentity(string name, UserInfo userInfo)
: this(name, userInfo.DisplayName, userInfo.UserId, userInfo.SiteId)
{
if (userInfo == null) throw new ArgumentNullException("userInfo");
this.AuthenticationType = userInfo.AutheticationType;
this.ClaimsIdentifier = userInfo.ClaimsIdentifier;
}
public SiteIdentity(FormsAuthenticationTicket ticket)
: this(ticket.Name, UserInfo.FromString(ticket.UserData))
{
if (ticket == null) throw new ArgumentNullException("ticket");
}
... not complete but i think you guess.
But first of all the structure of my webapi controller. I have created and extension controller, from where i extend all my webapi controllers:
public class _AuthorizedApiController : ApiController
{
protected readonly Site.Web.Domain.Services.IUserServices _userServices;
public _AuthorizedApiController(Site.Web.Domain.Services.IUserServices userServices)
{
if (userServices == null) throw new ArgumentNullException("userServices");
this._userServices = userServices;
}
protected int CurrentUserId
{
get { return this.User.SiteIdentity().UserId; }
}
private Site.Web.Domain.Models.User currentUser;
public Site.Web.Domain.Models.User CurrentUser
{
get
{
return this.currentUser ??
(this.currentUser = this._userServices.GetUserFromIdentity(this.User.SiteIdentity()));
}
}
protected int CurrentSiteId
{
get { return this.User.SiteIdentity().SiteId; }
}
}
so my webapi controller is:
public class ServicioController : _AuthorizedApiController
{
//http://www.asp.net/web-api/overview/web-api-routing-and-actions/routing-in-aspnet-web-api
//http://www.asp.net/web-api/overview/web-api-routing-and-actions/exception-handling
static readonly IServicioStatusRepository repositoryServicioStatus =
new ServicioStatusRepository(new Site.Web.Data.DatabaseFactory());
public ServicioController(Site.Web.Domain.Services.IUserServices userServices)
: base(userServices)
{
}
public IEnumerable<ServicioStatusA> GetServiciosStatus()
{
IEnumerable<ServicioStatusA> coleccion;
var estevalor = CurrentUser.SiteId;
}
As you can see i use IoC but the issue is that when i try to read CurrentUser.SiteId. I get this error:
Unable to cast object of type 'System.Web.Security.FormsIdentity' to type 'Site.Web.Models.SiteIdentity'.
in this return function:
public static Site.Web.Models.SiteIdentity SiteIdentity(this System.Security.Principal.IPrincipal principal)
{
return (Site.Web.Models.SiteIdentity)principal.Identity;
}
I use this "artifact" in global.asax.cs to keep session and information:
public override void Init()
{
this.PostAuthenticateRequest += this.PostAuthenticateRequestHandler;
// this.EndRequest += this.EndRequestHandler;
base.Init();
}
private void PostAuthenticateRequestHandler(object sender, EventArgs e)
{
if (IsWebApiRequest())
{
string esto = "popopopopo";
}
HttpCookie authCookie = this.Context.Request.Cookies[FormsAuthentication.FormsCookieName];
if (IsValidAuthCookie(authCookie))
{
// var formsAuthentication = ServiceLocator.Current.GetInstance<IFormsAuthentication>();
var formsAuthentication = new FormsAuthenticationService();
var ticket = formsAuthentication.Decrypt(authCookie.Value);
var siteIdentity = new SiteIdentity(ticket);
this.Context.User = new GenericPrincipal(siteIdentity, null);
// Reset cookie for a sliding expiration.
formsAuthentication.SetAuthCookie(this.Context, ticket);
}
}
and what i guess is that when there is a "normal" MVC call every works fine but when there is a webapi call i can recover everything from the cookie but i´ve got:
System.Security.Principal.GenericPrincipal
+ Identity: Site.Web.Model.SiteIdentity
instead of :
System.Security.Principal.GenericPrincipal
+ Identity: System.web.security.FormsIdentity
Thank you in advance for your support
ADEN-UM:
googling i try to keep the Identity in the thread also, so inside PostAuthenticateRequestHandler i type:
System.Threading.Thread.CurrentPrincipal = this.Context.User;
but now i have for all request the following error in any request not only webapi:

Mapped Objectified relationship with nhibernate can not initialize collection

I'm mapping a objectified relationship (the many->many mapping table contains properties),
following this guide.
The SQL generated(see exception) is working and returns what i want(strictly speaking it should have been an inner join?).
But I get a GenericADOException saying:
could not initialize a collection: [Questionnaires.Core.Questionnaire.Questions#CBDEDAFC183B4CD7AF1422423A91F589][SQL: SELECT questions0_.ida_questionnaire_id as ida4_2_, questions0_.ida_questionnaire_question_id as ida1_2_, questions0_.ida_questionnaire_question_id as ida1_5_1_, questions0_.question_no as question2_5_1_, questions0_.ida_question_id as ida3_5_1_, questions0_.ida_questionnaire_id as ida4_5_1_, question1_.ida_question_id as ida1_3_0_, question1_.ida_question_type_id as ida2_3_0_, question1_.description as descript3_3_0_, question1_.validate_max as validate4_3_0_, question1_.validate_min as validate5_3_0_ FROM ida_questionnaire_question questions0_ left outer join ida_question question1_ on questions0_.ida_question_id=question1_.ida_question_id WHERE questions0_.ida_questionnaire_id=?]
I'm guessing this is because Questionnaire is really mapping to QuestionnaireQuestion not Question(Questionnaire->hasMany->QuestionnaireQuestion<-hasMany<-Question). But I can't seem to find a way of going around this.

As for the reason I'm doing this:
One Questionnaire may have many Questions, One Question may have many Questionnaire.
I want to be able to give Questions some properties dependent on context (which Questionnaire is in), one question may be required in one questionnaire but not another etc. It's more than just order, that was just an example trying to keep it simple.
The exception is when trying to load data into Questionnaire.IList<Question>. And it's still thrown after I modify my IList<Questionnaire> to IList<QuestionnaireQuestion> and the respective mappings.
The problem then would be that Questionnaire.Questions is mapped as containing QuestionnaireQuestion but is of type Question. But if I try to map it as containing QuestionnaireQuestion my SQL does no join at all and it still fails.
Is this what I should do, just that I'm doing it wrong?
In the example I read he does it like I did as far as I can see, only difference is the newer version of FluentNhibernate that now uses Generics. So I need to specify the correct type.
Then, you should not have a List of Questionnaires in your Question class, but a List of QuestionnaireQuestion objects.
Are you sure you receive an ADO.NET Exception ?
Can you execute the generated query against your database ?
I don't understand your situation however, what is this QuestionairreQuestion class ? You're not using it in your Question class ?
I understand that you want to have an order in which your questions should occur.
So, if you have extra properties , I think you should use the QuestionairreQuestion class in your Question class.
But, if you only have this QuestionairreQuestion class in order to enforce an 'order' (and no other attributes), then, you could maybe use another Collection-Type instead of an IList.
There are collections in NHibernate which allow you to have ordered-collections (a map , for instance). So, you could use this collection in your Question class to hold Questionairre objects.
(ps: nhibernate generates an outer join, because you didn't specify in your mapping that the collection should not be null. So, an outer join is used because in some circumstances, it could be possible that you have a Question without Questionaires, as far as nhibernate is concerned).
