Hi i have class like above, and i want to create one-to-one mapping for "Creator" property on same class
how can i do this?
Try this:
References(x => x.Creator);
Make sure that you have a column named Creator_Id on your table. If you don't, you can use:
References(x => x.Creator).Column("YourColumnName")

As you see the models have references as one to many. list of project is not mapped here. there are more than one project and the project has more than one role and the role has more than one permission.
error is persister system not avialable.
can anyone look up and help me ?
public class Permission

public virtual int MId { get; set; }

How would I be able to Map an object inside of another with two columns that arent keys?
public class Car
{
public virtual int Id { get; set; }
public virtual int AccountId { get; set; }
}
public class UserAccount
{
public virtual int Id { get; set; }
public virtual int UserId{ get; set; }
public virtual int AccountId { get; set; }
}
public class User
{
public virtual int Id { get; set; }
public virtual int Name { get; set; }
}
Lets say I wanted to get all Cars with a User.Name of "joe". How would I map / query these with fluent nhibernate?
public Car()
{
Table("Car");
Id(x => x.Id).Column("ID").GeneratedBy.Native();
Map(x => x.AccountId);
References(x => x.Account); // ?? needs to map accountid with the Account.Id...
}
If you want to map a reference, you need the type, not the key.
public class Car
{
public virtual int Id { get; set; }
public virtual UserAccount Account { get; set; }
}
Then you would map it like this
public Car()
{
Table("Car");
Id(x => x.Id).Column("ID").GeneratedBy.Native();
References(x => x.Account, "AccountId");
}
User Class
public class User

My questions are:
I want to delete all roles of particular user? [Answered by danyolgiax]
Get roles of user
Can Any one guide me..
try .Inverse() on User (not on Role) and then:
user.Roles.Clear();
yourNhSession.SaveOrUpdate(user);
update
User user= yourNhSession.Get<User>(userId);
IList<Role> role= user.Roles;
I'm having problems mapping a relationaship between two entities when there are two columns involved in the mapping.
I'm modelling a state machine with two object types - State and Transition. Each process has its own state machine, so States and Transitions need to be identified by ProcessId. My entity classes are like this:
public class State
{
public virtual long Id { get; set; }
public virtual int ProcessId { get; set; }
public virtual int Ordinal { get; set; }
public virtual Process Process { get; set; }
public virtual ICollection<Transition> TransitionsIn { get; set; }
public virtual ICollection<Transition> TransitionsOut { get; set; }
}
public class Transition
{
public virtual long Id { get; set; }
public virtual long ProcessId { get; set; }
public virtual int FromStateNum { get; set; }
public virtual int ToStateNum { get; set; }
public virtual long StateActionId { get; set; }
public virtual Process Process { get; set; }
public virtual StateAction StateAction { get; set; }
public virtual State FromState { get; set; }
public virtual State ToState { get; set; }
}
I need the navigation properties (State.TransitionsIn, State.TransitionsOut, Transition.FromState, Transition.ToState) to be based on the ProcessId and the Ordinal number of the state. For example, Transition.FromState should navigate to the entity where t.ProcessId = s.ProcessId and t.FromStateNum = s.Ordinal.
I've tried the following mapping, but it complains that I'm using two columns to map to one (StateId).
public class StateMap : ClassMap<State>
{
public StateMap()
{
Id(x => x.Id);
HasMany(s => s.TransitionsIn)
.KeyColumns.Add("ProcessId", "ToStateNum")
.Inverse();
HasMany(s => s.TransitionsOut)
.KeyColumns.Add("ProcessId", "FromStateNum")
.Inverse();
}
}
public class TransitionMap : ClassMap<Transition>
{
public TransitionMap()
{
Id(x => x.Id);
References(t => t.FromState)
.Columns("ProcessId", "Ordinal");
References(t => t.ToState)
.Columns("ProcessId", "Ordinal");
}
}
How can I get this to work?
How about this mapping.. I have not tested it but just trying to give a direction.
public class StateMap : ClassMap<State>
{
public StateMap()
{
Id(x => x.Id);
HasMany(s => s.TransitionsIn)
.KeyColumn("ProcessId")
.KeyColumn("ToStateNum").PropertyRef("Ordinal")
.Inverse();
HasMany(s => s.TransitionsOut)
.KeyColumn("ProcessId")
.KeyColumn("FromStateNum").PropertyRef("Ordinal")
.Inverse();
}
}
public class TransitionMap : ClassMap<Transition>
{
public TransitionMap()
{
Id(x => x.Id);
References(t => t.FromState)
.Columns("ProcessId", "FromStateNum");
References(t => t.ToState)
.Columns("ProcessId", "ToStateNum");
}
}
I'm feeling dumb.
public class Uber
{
public Foo Foo { get; set; }
public Bar Bar { get; set; }
}
public class Foo
{
public string Name { get; set; }
}
...
var ubercharged = session.CreateCriteria(typeof(Uber))
.Add(Expression.Eq("Foo.Name", "somename"))
.UniqueResult<Uber>();
return ubercharged;
This throws a "could not resolve property" error.
What am I doing wrong? I want to query for an Uber object that has a property Foo which has a Name of "somename".
updated with real life example, repository call, using fluent nhibernate:
public UserPersonalization GetUserPersonalization(string username)
{
ISession session = _sessionSource.GetSession();
var personuser = session.CreateCriteria(typeof(UserPersonalization))
.Add(Expression.Eq("User.Username", username))
.UniqueResult<UserPersonalization>();
return personuser;
}
The classes/mappings:
public class User
{
public virtual Guid UserId { get; set; }
public virtual string Username { get; set; }
public virtual string Email { get; set; }
public virtual string PasswordHash { get; set; }
public virtual string PasswordSalt { get; set; }
public virtual bool IsLockedOut { get; set; }
public virtual bool IsApproved { get; set; }
}
public class Person
{
public virtual int PersonId { get; set; }
public virtual string Name { get; set; }
public virtual Company Company { get; set; }
}
public class UserPersonalization
{
public virtual int UserPersonalizationId { get; set; }
public virtual Person Person { get; set; }
public virtual User User { get; set; }
}
public class UserMap : ClassMap<User>
{
public UserMap()
{
Id(x => x.UserId).GeneratedBy.Guid().ColumnName("UserId");
Map(x => x.Username);
Map(x => x.PasswordHash);
Map(x => x.PasswordSalt);
Map(x => x.Email);
Map(x => x.IsApproved);
Map(x => x.IsLockedOut);
}
}
public class UserPersonalizationMap : ClassMap<UserPersonalization>
{
public UserPersonalizationMap()
{
WithTable("UserPersonalization");
Id(x => x.UserPersonalizationId).ColumnName("UserPersonalizationId");
References(x => x.Person).ColumnName("PersonId");
References(x => x.User).ColumnName("UserId");
}
}
public class PersonMap : ClassMap<Person>
{
public PersonMap()
{
Id(x => x.PersonId).ColumnName("PersonId");
Map(x => x.Name);
References(x => x.Company).ColumnName("CompanyId");
}
}
Try this:
var ubercharged = session.CreateCriteria(typeof(Uber))
.CreateCriteria("Foo")
.Add(Restrictions.Eq("Name", "somename"))
.UniqueResult<Uber>();
Can you sort using "ubercharged.AddOrder(Order.asc("Foo.Name")) syntax? This syntax should work in NHib 2.01. If not, your maps are not working correctly.
Stuart's answer should work fine for you though.
