I was wondering why my XAF WinForms EF application was slow loading a detail view.
Then I learned how to capture FirstChance Exceptions and discovered I was experiencing an IndexOutOfRange exception as described here
Sometimes I want to include a non mapped property in my business object such as Job in example.
public class OrderLineResult
{
public int LineId { get; set; }
public int Quantity { get; set; }
public string Description { get; set; }
[Browsable(false)] public int JobId { get; set; }
[NotMapped] [Browsable(false)] public virtual Job Job { get; set; }
}
And I have a method to get the data inside the OrderLineResult class
public static OrderLineResult[] GetData(int headId)
{
using var connect = new MyDbContext()
const string sql =
#"SET NOCOUNT ON;
create table #temp( JobId int, Quantity int, LineId int, Description )
/* code to populate the table */
select JobId,LineId,Quantity, Description from #temp"
var results = connect.Database.SqlQuery<OrderLineResult>(sql,headId).ToArray();
return results.ToArray();
}
}
Yet the IndexOutOfRange exception occurs for the Job property.
The call stack is
System.IndexOutOfRangeException

This feels like a cludge,
I added

The issue is pretty straightforward — An error occurred when trying to create a controller of type 'WebHaber.Admin.Controllers.AccountController'. Make sure that the controller has a parameterless public constructor.
You're trying to use Autofac to inject IKullaniciRepository service into the AccountController but the compiler couldn't find one although you've the declared the service registration at BootStrapper.cs
Therefore it's likely that BootStrapper.cs's RunConfig never get invoked. Just place a call (e.g. BootStrapper.RunConfig()) to Application_Start() method in Global.asax and you're fine.
#Zephyr thank you for help.
I added new global.asax file.
Because my Application_Start() was not firing.

I have lazy loading off and my ApplicationUsers class looks like this
namespace WebApp.Core.Contracts
{
public class ApplicationUsers : IdentityUser
{
public bool IsActive { get; set; }
public string LockoutReason { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Photo { get; set; }
public virtual List<AspNetUsersSites> AspNetUsersSites { get; set; }
// a collection of roles that can be written to, since it needs to be evaluated earlier before it's disposed of
[ForeignKey("Id")]
public virtual List<IdentityRole> IdentityRoles { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUsers> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
return userIdentity;
}
public async Task<IList<string>> GenerateUserRolesAsync(UserManager<ApplicationUsers> manager, string userId)
{
var userRoles = await manager.GetRolesAsync(this.Id);
return userRoles;
}
public async Task DeleteUser(UserManager<ApplicationUsers> manager, string username)
{
var user = manager.FindByName(username);
await manager.DeleteAsync(user);
}
}
My Linq query looks like this
public static List<Contracts.ApplicationUsers> GetUsersForSiteWithRoles(int SiteID){
using (CMSContext cntx = new CMSContext())
{
var users = cntx.Users
.Include(m => m.IdentityRoles)
.Include(s => s.AspNetUsersSites)
.Where(i => i.AspNetUsersSites.Where(s => s.SiteID == SiteID).Count() > 0).ToList();
return users;
}
}
What is wrong with the navigational property I added and/or the query. All I am really trying to do is return users with their roles that are stored in my database.
Thank you!
First, it should be:
public virtual ICollection<IdentityRole> IdentityRoles { get; set; }
Not List<IdentityRole>.
Second, this relationship already exists on ApplicationUser through inheritance from IdentityUser in the Roles property. You're creating a secondary relationship here that will never be used by the Identity framework.
Also, for what it's worth, if you want your AspNetUserSites to follow the table name scheme of the Identity tables, you need only specify the Table attribute on the class. Naming your class in this way is obtuse. For example:
[Table("AspNetUserSites")]
public class Site
{
...
}
Then you just have a nice class like Site instead of AspNetUserSite
UPDATE
IdentityUserRole is just the join table between IdentityUser and IdentityRole. In the default implementation there's not a whole lot of point in its existence, but you could potentially extend the Identity classes to attach additional information on the relationship that way.
Anyways, if you just want to get at the actual IdentityRoles, just do something like:
var roleIds = user.Roles.Select(r => r.RoleId).ToList();
var roleNames = db.Roles.Where(r => roleIds.Contains(r.Id)).Select(r => r.Name);
I'm trying to use Code First Migrations with IdentityUser.
Here's my dbContext
public class JbDb : IdentityDbContext<User>
{
public JbDb()
: base(ConfigurationManager.ConnectionStrings["JbDb"].ConnectionString)
{
}
public IDbSet<User> User { get; set; }
public virtual IDbSet<T> DbSet<T>() where T : class
{
return Set<T>();
}
public virtual void Commit()
{
base.SaveChanges();
}
}
internal class Initialiser : CreateDatabaseIfNotExists<JbDb>
{
protected override void Seed(JbDb context)
{
context.SaveChanges();
}
}
Here's the code for User model
[Table("User", Schema = "Security")]
public class User:IdentityUser
{
public string UserId
{
get { return Id; }
}
public string Email { get; set; }
public bool IsEmailVerified { get; set; }
public bool IsDeleted { get; set; }
}
Connection String is like this:
<add name="JbDb" connectionString="Data Source=CENLP\HRMSQL;Initial Catalog=JbDb;Integrated Security=True" providerName="System.Data.SqlClient" />
but when i'm trying to enable the migrations, it gives an error saying

I have been trying to get results using HQL for two classes. It works for one table but does not work for two tables.
The two entities below;
public class A_CUSTOMER
{
public virtual string CUSTOMER_NO { get; set; }
public virtual string ADDRESS_LINE { get; set; }
public virtual IList<A_ACCOUNT> ACCOUNTS { get; set; }
}
public class A_ACCOUNT
{
public virtual string AC_NO { get; set; }
public virtual string CUST_NO { get; set; }
public virtual string CCY { get; set; }
public virtual string AVL_BAL { get; set; }
public virtual A_CUSTOMER CUSTOMER { get; set; }
}
Mappings for the classes below;
public class A_CUSTOMERMap:ClassMap<A_CUSTOMER>
{
public A_CUSTOMERMap()
{
Id(x => x.CUSTOMER_NO);
Map(x => x.ADDRESS_LINE);
HasMany(x => x.ACCOUNTS).KeyColumns.Add("CUST_NO");
}
}
public class A_CUST_ACCOUNTMap:ClassMap<A_CUST_ACCOUNT>
{
public A_CUST_ACCOUNTMap()
{
Id(x => x.AC_NO);
Map(x=>x.CUST_NO);
Map(x => x.AVL_BAL);
Map(x => x.CCY);
References(x => x.CUSTOMER,"CUST_NO");
}
}
Now, I have a code like this in my controller:
string myString = "1001,1002,1003,1004,1005";
var indNumbers = myString.Split(',');
string qry = #"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE"+
"from A_ACCOUNT as h,A_CUSTOMER g "+
"where h.CUST_NO=g.CUSTOMER_NO AND h.AC_NO IN (:list)";
;
res = session.CreateQuery(qry)
.SetParameterList("list", indNumbers)
.List();
I have also tried different query string:
string qry = #"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE"+
"from A_ACCOUNT as h left join A_CUSTOMER g on "+
"h.CUST_NO=g.CUSTOMER_NO"+
"where h.AC_NO IN (:list)";
The error encountered below, any help will be much appreciated.

One way to rerite this is to drop all occurrences of quotes:- " + " e.g.
var qry = #"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE
from A_ACCOUNT as h,A_CUSTOMER g
where h.CUST_NO=g.CUSTOMER_NO AND h.AC_NO IN (:list)";
Notice in my sample I only have a started " (quote) and an ending ".
Rippo was right about the spacing and quotes, in addition i noticed i was still referring to the Class names in HQL instead of the alias Reference names
I changed from
"A_ACCOUNT as h left join A_CUSTOMER g on "
to
"from A_ACCOUNT as h left join h.CUSTOMER g on "
It should have been
string qry = #"select h.AC_NO,h.BRANCH_CODE,h.CUST_NO,h.CCY,h.AVL_BAL ,g.ADDRESS_LINE"+
"from A_ACCOUNT as h left join h.CUSTOMER g on "+
"h.CUST_NO=g.CUSTOMER_NO"+

i'm creating a database with entity framework, in an mvc asp.net application, using code first.
I'm new to the argument so be patient... I've created the database for the first time and all seems to be right; but couse of i didn't create a DropCreateDatabaseIfModelChanges method to change the tables i decided to manually delete the database.
The problem is that the database is not recreating!
I've implemented the initializer and it is in a different class from the context...

InnerException:
override Seed function in your WidgetDbInitializer class and try to add some data to your database .
protected override void Seed(WidgetDbContext context)
{
context.yourodel.add(new class() )
}
first check your overriden seed invoke correctly , then if your database dose not generated you will get an exception .
Solved the problem:
public class Widget
{
//This properties rapresent the primary key for entity framework
[Key]
public int WidgetID { get; set; }
//Foreing key to the column where this widget is stored
public virtual int ColumnID { get; set; }
//The title of the widget
public string Title { get; set; }
//Controller of the Widget, this property may be used on the RenderAction call
public string Controller { get; set; }
//ActionMethod of the Widget, this property may be used on the RenderAction call
public string ActionMethod { get; set; }
//The Type of the Model, used on deserialization
public Type ModelType { get; set; }
//The context of the widget
public string SerializedModel { get; set; }
}
The database just didn't accept the type "Type", all working fine as soon as I deleted that field... I just didn't look at it because it was working with the "Object" type, didn't expect it doesnt with Type..
