I asked a question earlier but I don't think I asked it correctly.
in my asp.net mvc application I am using aspnetusers for my login and registration.
If I have another model for Employees containing their information, How do I connect these two models so when a user logs in, it grabs their information from the employee table to be used. I created the Employees Model with sql server and used ado.net entity data model to use it in visual studio.
Employee Model:
public partial class Employee
{
public int UserID { get; set; }
[Key]
public int EmployeeID { get; set; }
public string FullName { get; set; }
public string Email { get; set; }
public System.DateTime StartDate { get; set; }
public int RoleID { get; set; }
public int ShiftID { get; set; }
public int AreaID { get; set; }
public int DisciplineID { get; set; }
public int SiteID { get; set; }
public int ALCategory { get; set; }
public int HoursTaken { get; set; }
public Nullable<int> AwardedLeave { get; set; }
public Nullable<int> TotalHoursThisYear { get; set; }
public int HoursCarriedForward { get; set; }
public Nullable<int> EntitlementRemainingThisYear { get; set; }
public string Comments { get; set; }
public int SickLeaveTaken { get; set; }
public Nullable<int> SickLeaveEntitlement { get; set; }
public Nullable<int> SickLeaveEntitlementRemaining { get; set; }
public int StudyLeaveEntitlement { get; set; }
public int StudyLeaveTaken { get; set; }
public Nullable<int> StudyLeaveRemaining { get; set; }
public int ExamLeaveTaken { get; set; }
public int ForceMajeure { get; set; }
public int BereavementLeaveTaken { get; set; }
public int MaternityLeaveTaken { get; set; }
public int ParentalLeaveTaken { get; set; }
public int AdoptionLeaveTaken { get; set; }
public string ManagerEmail { get; set; }
public string AreaManagerEmail { get; set; }
public virtual Area Area { get; set; }
public virtual Discipline Discipline { get; set; }
public virtual Shift Shift { get; set; }
public virtual Site Site { get; set; }
public virtual Employee Employee1 { get; set; }
public virtual Employee Employee2 { get; set; }
}
And the log-in model:
public class LoginViewModel
{
[Required]
[Display(Name = "Email")]
[EmailAddress]
public string Email { get; set; }
[Required]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[Display(Name = "Remember me?")]
public bool RememberMe { get; set; }
}
So can I connect these two?
Does it matter that I use database first model?
Could I use a Foreign Key to connect by email?
I want to use it for example to filter a table of employees to only show the employees who have the same siteID for the user logged in.
So when a user logs in, I want them to only see employees with the same site as themselves on the employee HTML table.
After successful login, you will get Id of AspNetUser. Take foreign key reference of column Id from AspNetUser table in your Employee table. By doing this, you can achieve expected result. Simply one more thing you need to add in your Employee model as mentioned below:
public virtual ApplicationUser ApplicationUser { get; set; }

This is the first time I have attempted to join information from one database to the other. I have a accounting database and a regular site database. Trying to keep them separate. I have a page that shows Transactions but am getting the information for a few of the columns from the regular database by way of Id's. Below is my Model. I am showing nothing in the fields for the items in the other database.
public class Transaction
{
[Key]
public Guid TransactionId { get; set; }
public string Description { get; set; }
public int? CompanyId { get; set; }
public Guid? VendorId { get; set; }
public string InCheckNumber { get; set; }
public string OutCheckNumber { get; set; }
public string InvoiceNumber { get; set; }
public string PurchaseOrderNumber { get; set; }
public Guid LedgerAccountId { get; set; }
public decimal? DebitAmount { get; set; }
public decimal? CreditAmount { get; set; }
public DateTime TransactionDate { get; set; }
public string ModifiedBy { get; set; }
public DateTime? ModifiedDate { get; set; }
public string SavedDocument { get; set; }
public DateTime CreatedDate { get; set; }
public string CreatedBy { get; set; }
public bool IsCredit { get; set; }
public bool IsDebit { get; set; }
public Guid Type { get; set; }
[ForeignKey("LedgerAccountId")]
public LedgerAccount LedgerAccount { get; set; }
[ForeignKey("CompanyId")]
public CompanyNames Company { get; set; }
[ForeignKey("VendorId")]
public Vendors Vendor { get; set; }
}
I have added the 'using' of the General.Entities to this model. Is there something else i need to add for this?
Thanks in advance.
UPDATE:
See Question - Link to answer of question
I have an EF model to is connected 1 to 1 for many tables but I am having trouble connecting a 1 to many table. Currently using EF6 on .Net 4.8. The error I am recieving is "Multiplicity is not valid in Role '' in relationship 'Login_Users'. Because the Dependent Role refers to the key properties, the upper bound of the multiplicity of the Dependent Role must be '1'"
The main table is
Users
public partial class Users
{
public Users()
{
this.Login = new HashSet<Login>();
this.Phone = new HashSet<Phone>();
}
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public string Name { get; set; }
public string Email { get; set; }
public System.DateTime BirthDate { get; set; }
public int LastFourSSN { get; set; }
public Nullable<int> AddressId { get; set; }
public virtual Address Address { get; set; }
public virtual ICollection<Login> Login { get; set; }
public virtual ICollection<Phone> Phone { get; set; }
}
One to one tables
public partial class Login
{
public Login()
{
this.Login_Track = new HashSet<Login_Track>();
this.Policy = new HashSet<Policy>();
}
public string Username { get; set; }
public string Password { get; set; }
[Key, ForeignKey("Users")]
public Nullable<int> UserId { get; set; }
public System.DateTime CreationDate { get; set; }
public Nullable<System.DateTime> LastLoginDate { get; set; }
public virtual Users Users { get; set; }
}
Address
public partial class Address
{
public Address()
{
this.Users = new HashSet<Users>();
}
[Key, ForeignKey("Users")]
public int Id { get; set; }
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string City { get; set; }
public string County { get; set; }
public string State { get; set; }
public string PostalCode { get; set; }
public virtual ICollection<Users> Users { get; set; }
}
1 to many table
public partial class Phone
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public string Number { get; set; }
public string Type { get; set; }
[ForeignKey("Users")]
public Nullable<int> UserId { get; set; }
public virtual Users Users { get; set; }
}
In simple relational terms, I want each entry of ContractDetails to be assigned to either a Site OR a Company, not both at the same time, and one of them must be selected or there is no link at all. I'm not quite sure how to represent this in entity framework. My Model at Present:
Company Model:
public class Company
{
public int ID { get; set; }
public string Company_Name { get; set; }
public string Company_Prefix { get; set; }
public virtual ICollection<Site> Sites { get; set; }
}
Contract Details Model:
public class ContractDetails
{
public int ContractDetailsID { get; set; }
public int ContractTypeID { get; set; }
public int ContractRenewalPeriodID { get; set; }
public int? CompanyID { get; set; }
public int? SiteID { get; set; }
[Required, StringLength(10)]
public string Reference { get; set; }
[Display(Name = "Contract Start Date"), DataType(DataType.Date)]
public DateTime? Contract_Start_Date { get; set; }
[Display(Name = "Contract End Date"), DataType(DataType.Date)]
public DateTime? Contract_End_Date { get; set; }
[Column(TypeName = "text")]
public string Notes { get; set; }
public string Direct_Debit_Reference { get; set; }
public virtual Company Company { get; set; }
public virtual Site Site { get; set; }
public virtual ContractType ContractType { get; set; }
public virtual ContractRenewalPeriod ContractRenewalPeriod { get; set; }
}
Site Model:
public class Site
{
public int ID { get; set; }
public string Site_Name { get; set; }
public string Site_TelephoneNumber { get; set; }
public string Site_City { get; set; }
public int CompanyID { get; set; }
public virtual Company Company { get; set; }
}
Just implement the IValidatableObject on ContractDetails class. On Validate method put the validation logic. If the object is not valid you must return a collection of ValidationResult. when saving the object, EF will execute the Validate method and verify that your ContractDetails object is coherent.
my model classes first:
public class Person
{
[Required, Key]
public int ID { get; set; }
[Required]
public string Name { get; set; }
[Required]
public string LearntSkillsAndLevelOfSkills { get; set; }
public string ProfileImage { get; set; }
public string City { get; set; }
public string PhoneNr { get; set; }
[Required]
public string Email { get; set; }
public string Hobbys { get; set; }
public string SkillsToLearn { get; set; }
public string Stand { get; set; }
public int YearsOfWorkExperience { get; set; }
public string HobbyProjectICTRelated { get; set; }
public string ExtraInfo { get; set; }
public string Summary { get; set; }
public int UserId { get; set; }
[ForeignKey("UserId")]
public virtual UserProfile profile { get; set; }
}
[Table("UserProfile")]
public class UserProfile
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string UserName { get; set; }
public Nullable<int> ID { get; set; }
public virtual Person personprofile { get; set; }
}
when i run this however it gives me this exception: The principal end of this association must be explicitly configured
i've searched this error but it doesn't clarify it for me... so i absolutely have no clue how to fix this. Basically i want to link my Person class to the Userprofiles so that i can create a login mechanism that automatically lets 1 person who makes an account on the site get 1 Profile to Edit to his own information. He's however not allowed to modify other people their accounts.
I hope this makes my problem clear and that somebody can help me :). i'm using EF 6 btw and i get the error in the class InitializeSimpleMembershipAttribute that comes standard with the MVC example of ASP.net
Greetings and thanks in advance,
Marijn
I managed to get it working with these codes in the models:
[Table("UserProfile")]
public class UserProfile
{
[Key, DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string UserName { get; set; }
public virtual Person personprofile { get; set; }
}
public class Person
{
[ForeignKey("profile"), Key]
public int UserId { get; set; }
[Required]
public string Name { get; set; }
[Required]
public string LearntSkillsAndLevelOfSkills { get; set; }
public string ProfileImage { get; set; }
public string City { get; set; }
public string PhoneNr { get; set; }
[Required]
public string Email { get; set; }
public string Hobbys { get; set; }
public string SkillsToLearn { get; set; }
public string Stand { get; set; }
public int YearsOfWorkExperience { get; set; }
public string HobbyProjectICTRelated { get; set; }
public string ExtraInfo { get; set; }
public string Summary { get; set; }
public UserProfile profile { get; set; }
}
I have the following classes, a challenge has many submissions and it also has a winner.
The problem is that in my database Entity framework has created two columns on the Submissions table [ChallengeId] & [Challenge_ChallengeId] when I save an object it is added to the ChallengeId Column but relationship is being held on the Challenge_ChallengeId column.
Is there an issue with my models that is causing this or is some way I can set to hold the relationship and save to the same column?
Thanks!
public class Submission
{
[Key]
public Int32 SubmissionId { get; set; }
public DateTime Created { get; set; }
public Int32 ChallengeId { get; set; }
[ForeignKey("ChallengeId")]
public virtual Challenge Challenge { get; set; }
public String YouTubeVideoCode { get; set; }
public virtual IList<SubmissionVote> Votes { get; set; }
}
public class Challenge
{
[Key]
public Int32 ChallengeId { get; set; }
[Required]
public String ChallengeName { get; set; }
public virtual IList<Submission> Submissions { get; set; }
public Int32? OverallWinnerId { get; set; }
[ForeignKey("OverallWinnerId")]
public virtual Submission OverallWinner { get; set; }
}
I think you could benefit from just using the conventions and also using the shorthand keywords as data types. I think the error is because you have annotated the proxy with a ForeignKey attribute. Try this
public class Submission
{
public int SubmissionId { get; set; }
public DateTime Created { get; set; }
public int ChallengeId { get; set; }
public string YouTubeVideoCode { get; set; }
public virtual Challenge Challenge { get; set; }
public virtual IList<SubmissionVote> Votes { get; set; }
}
public class Challenge
{
public int ChallengeId { get; set; }
[Required]
public string ChallengeName { get; set; }
public int? OverallWinnerId { get; set; }
public virtual Submission OverallWinner { get; set; }
public virtual IList<Submission> Submissions { get; set; }
}
I'm pretty sure that Entity Framework uses a convention based approach, and the easiest way to fix this is to use the Id name instead of ChallengeId and SubmissionId
public class Submission
{
[Key]
public Int32 Id { get; set; }
public DateTime Created { get; set; }
public Int32 ChallengeId { get; set; }
[ForeignKey("ChallengeId")]
public virtual Challenge Challenge { get; set; }
public String YouTubeVideoCode { get; set; }
public virtual IList<SubmissionVote> Votes { get; set; }
}
public class Challenge
{
[Key]
public Int32 Id { get; set; }
[Required]
public String ChallengeName { get; set; }
public virtual IList<Submission> Submissions { get; set; }
public Int32? OverallWinnerId { get; set; }
[ForeignKey("OverallWinnerId")]
public virtual Submission OverallWinner { get; set; }
}
