I'm still new to .NET Core. I have this character that I want to store in SQLite using an entity.
But by default, Character, CharacterData and CharacterLine are mapped to different tables.
Is there anyways to make entity map them to the same table?
public class Character
{
public int CharacterID { get; set; }
public string characterName { get; set; }
public string characterDisplayName { get; set; }
public string characterIconPath { get; set; }
public CharacterData characterInfo { get; set; }
}
public class CharacterData
{
public int CharacterDataID { get; set; }
public Gender Gender { get; set; }
public int Height { get; set; }
public DateTime BirthDay { get; set; }
public CharacterLine lines { get; set; }
}
public class CharacterLine
{
public int CharacterLineID { get; set; }
public string line1 { get; set; }
public string line2 { get; set; }
public string line3 { get; set; }
public string line4 { get; set; }
}
I have the following models,do I define it Ok?
User is the main Entity and can have 0..1 to * (zero /one to many relationship ) address.
2.User can have have 0..1 to 1 (one to one userPass )
This is the main table
public class User
{
[Key]
[Required]
[DatabaseGenerated(DatabaseGeneratedOption.None)]
public string UserId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string Phone { get; set; }
public string PhoneWork { get; set; }
public string WorkingAt { get; set; }
public virtual UserPass UserPass { get; set; }
public virtual ICollection<Address> Addresses { get; set; }
}
public class ConfigModelDbContext : DbContext
{
public DbSet<User> User { get; set; }
public DbSet<Address> Addresses { get; set; }
public DbSet<UserPass> UserPasses { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
modelBuilder.Entity<User>()
.HasOptional(c => c.Addresses).WithRequired(addresses => new User());
modelBuilder.Entity<User>()
.HasOptional(c => c.UserPass).WithRequired(pass => new User());
}
}
Address Class
public class Address
{
[Key]
[ForeignKey("User")]
public string UserId { get; set; }
public string UserAddress { get; set; }
}
Userpass class
public class UserPass
{
[Key]
[ForeignKey("User")]
public string UserId { get; set; }
public string User { get; set; }
public string Password { get; set; }
}
i also created classes same as above but can it create relationship directly on database table?
at first I offer you to use data annotation instead of fluent api always.
then correct AddressClass like below:
public class Address
{
[Key]
public int Id { get; set; }
[ForeignKey("UserId")]
public User User { get; set; }
public string UserId { get; set; }
public string UserAddress { get; set; }
}
This will create Ralationship.

I've been reading through lots of articles trying to learn MVC4, but I'm stumped as to why my entity is not getting updated to database.
I've been trying to modify the MVC4 VS2012 Internet template.
So, here's the Controller action:
[HttpPost, ActionName("Approve")]
[Authorize]
public ActionResult ApproveConfirmed(long id)
{
using (StudentiContext context = new StudentiContext())
{
// context.Configuration.AutoDetectChangesEnabled = false;
var studente = (from d in context.STUDENTI_STRANIERI_MASTER_REG
where d.ID_PERSONA == id
select d).Single();
STUDENTI_STRANIERI_MASTER_REG st2 = studente;
st2.ESITO = 1;
//studente.ESITO = 1;
var statos = context.Entry(studente).State;
Console.WriteLine("Before DetectChanges: {0}",statos);
//context.ChangeTracker.DetectChanges();
context.Entry(studente).State = EntityState.Modified;
context.Entry(studente).CurrentValues.SetValues(st2);
// var tracked = context.ChangeTracker.Entries();
context.Entry(studente).Property( o => o.ESITO ).IsModified = true;
TryUpdateModel(studente);
context.SaveChanges();
Console.WriteLine("After DetectChanges: {0}",statos);
return RedirectToAction("PrivateIndex");
}
}
The aim is just to update one property, ESITO and set it to 1. Currently its value is 2.
This is the model:
namespace MvcStudenti2.Models
{
using System;
using System.Collections.Generic;
public partial class STUDENTI_STRANIERI_MASTER_REG
{
public long ID_PERSONA { get; set; }
public string COGNOME { get; set; }
public string NOME { get; set; }
public string SESSO { get; set; }
public System.DateTime DATA_NASCITA { get; set; }
public long ID_STATO_NASCITA { get; set; }
public string LUOGO_NASCITA_ESTERO { get; set; }
public string CODICE_FISCALE { get; set; }
public string TITOLO_POSSEDUTO { get; set; }
public Nullable<short> DURATA_TITOLO { get; set; }
public string VOTAZIONE { get; set; }
public string UNI_PROVENIENZA { get; set; }
public long ID_STATO_UNI { get; set; }
public string CERT_LINGUISTICA { get; set; }
public string CERT_PUNTEGGIO { get; set; }
public string NOTE { get; set; }
public System.DateTime DATA_RICHIESTA { get; set; }
public short ESITO { get; set; }
public string CDS_COD { get; set; }
public string EMAIL { get; set; }
public string NUMERO_TELEFONO { get; set; }
public string INDIRIZZO { get; set; }
public string CAP_INDIRIZZO { get; set; }
public string CITTA { get; set; }
public long ID_STATO_INDIRIZZO { get; set; }

public string MADRELINGUA { get; set; }
public Nullable<short> CERT_TOEFL_PUNT { get; set; }
public string CERT_FIRSTCERT_GRADE { get; set; }
public Nullable<short> CERT_FIRSTCERT_PUNT { get; set; }
public byte[] FILE_CV { get; set; }
public byte[] FILE_CARRIERA { get; set; }
public byte[] FILE_CERT_LINGUA { get; set; }
public byte[] FILE_DOC_IDENTITA { get; set; }
public string PWD { get; set; }

public string FILE_CERT_LINGUA_NOME { get; set; }
public string FILE_DOC_IDENTITA_NOME { get; set; }
public string FILE_CV_TIPO { get; set; }
public string FILE_CARRIERA_TIPO { get; set; }
public string FILE_CERT_LINGUA_TIPO { get; set; }
public string FILE_DOC_IDENTITA_TIPO { get; set; }
public Nullable<short> STATO { get; set; }
public Nullable<short> VALUTATO { get; set; }
public Nullable<short> ARCHIVIATO { get; set; }
public string CDS_COD_2 { get; set; }
public Nullable<short> MAIL_INVIATA { get; set; }
public string LINK_ULTIMO_CORSO { get; set; }
public Nullable<short> ATTIVO { get; set; }
public byte[] FILE_LETTERA_ACCETTAZIONE { get; set; }
public string FILE_LETTERA_ACCETTAZIONE_NOME { get; set; }
public string FILE_LETTERA_ACCETTAZIONE_TIPO { get; set; }
}
}
Everywhere I read I find that SaveChanges() should be enough, possibly after the EntityState.Modified.
I can correctly edit the entity, if I pass the whole entity to the Action, but in this case the Approve view is a built on a Detail template, so I don't have anything to POST from it (and I'd prefer not to: I could insert a hidden field and post just that, but I'm trying to update a single filed from code, and I'm not sure if the whole entity would get updated or overwritten ).
statos goes to "modified", if I understand correctly, because I have done a query on the entity.
Another thing I don't understand is why ESITO gets update -also- in studente, but then reverts to "2" after SaveChanges().
Are property changes being detected? I've wrapped every Action in a using block, as suggested elsewhere, so not to have multiple contextx/instances around.
Could anyone please point me to what I'm doing wrong? The code above is probably over-redundant, but I've been trying everything I have found on SO.
Thanks, everyone.
The following is all that is required to change the ESITO property.
[HttpPost, ActionName("Approve")]
[Authorize]
public ActionResult ApproveConfirmed(long id)
{
using (StudentiContext context = new StudentiContext())
{
// context.Configuration.AutoDetectChangesEnabled = false;
var studente = (from d in context.STUDENTI_STRANIERI_MASTER_REG
where d.ID_PERSONA == id
select d).Single();
studente.ESITO = 1;
context.SaveChanges();
return RedirectToAction("PrivateIndex");
}
}
I'm having trouble with parsing a twitter flow, this code is returning this error message:
No parameterless constructor defined for type of
'System.Collections.Generic.IEnumerable`1[[Xxxx.Website.Templates.WidgetViews.Tweet,
Dolphin, Version=1.0.4801.24288, Culture=neutral,
PublicKeyToken=null]]'.
I would very much appreciate your help!
public partial class TwitterWidgetView
{
protected override void OnLoad(System.EventArgs e)
{
string listName = "sas";
string twitterListPath = "https://search.twitter.com/search.json?q=" + listName;
WebClient wc = new WebClient();
var json = wc.DownloadString(twitterListPath);
JavaScriptSerializer ser = new JavaScriptSerializer();
var tweetList = ser.Deserialize<IEnumerable<Tweet>>(json);
}
}
public class Metadata
{
public string result_type { get; set; }
}
public class Tweet
{
public Tweet()
{}
public string created_at { get; set; }
public string from_user { get; set; }
public int from_user_id { get; set; }
public string from_user_id_str { get; set; }
public string from_user_name { get; set; }
public object geo { get; set; }
public object id { get; set; }
public string id_str { get; set; }
public string iso_language_code { get; set; }
public Metadata metadata { get; set; }

public long? in_reply_to_status_id { get; set; }
public string in_reply_to_status_id_str { get; set; }
}
public class RootObject
{
public RootObject()
{}
public double completed_in { get; set; }
public long max_id { get; set; }
public string max_id_str { get; set; }
public string next_page { get; set; }

public List<Tweet> results { get; set; }
public int results_per_page { get; set; }

}
Try using a list instead
var tweetList = ser.Deserialize<List<Tweet>>(json);
I got null value for byte array in json web service when deserializing.but it returns byte array when invoked from browser.
C# Code:
var url = re.DownloadString("XXXX/ListService.svc/lstFooddtl/1/21");
var a = JsonConvert.DeserializeObject<FooddtlResult>(url);
In a i got null for food_photo...when i deserialize...
c# Class:
public class photo
{
public byte[] food_photo { get; set; }
}
public class Food
{
public int food_id { get; set; }
public string food_name { get; set; }
public photo[] food_photo { get; set; }
public string unitcost { get; set; }
}
public class FooddtlResult
{
public Food[] Result { get; set; }
}
{"Result":[{"food_id":"61","food_name":"Idli","food_photo":[255,216,255,224,0,....217],"unitcost":null}]}
Your model does not match the JSON. For correct deserialization change your Food class to
public class Food
{
public int food_id { get; set; }
public string food_name { get; set; }
public byte[] food_photo { get; set; }
public string unitcost { get; set; }
}
and remove the photo class.
Otherwise, if you want to keep the model structure, then correct JSON should be:
{"Result":[{"food_id":"61","food_name":"Idli","food_photo":[{"food_photo":[255,216,255,224,0,....217]},{"food_photo":[255,...]},...],"unitcost":null}]}
