SaveChanges RRS feed

  • Question

  • Hallo!

    In my controller, I have an Details method to display the view, and an Details POST method to save the changes:

     public ActionResult Details()
                return View();
            public ActionResult Details(CandidatesSkills candidateSkills)
                return RedirectToAction("Create","Home");
    But I'm getting an error saying:

    The INSERT statement conflicted with the FOREIGN KEY constraint "FK_CandidatesSkills_Candidate". The conflict occurred in database "Candidates", table "dbo.Candidate", column 'CandidateID'.
    The statement has been terminated.

    Please help.

  • Hello,

    I when you are inserting data in database that time your foreign key field goes as null or that value is not present in your primary key table so check this.

  • This is my table definition:

    CREATE TABLE Candidate
    CandidateID    int    IDENTITY(1,1) PRIMARY KEY,
    FirstName    nvarchar(50) NOT NULL,   
    LastName    nvarchar(50) NOT NULL,
    Email    nvarchar(50)  NOT NULL

    create table CandidatesSkills
    CandidateID int,
    SkillID int,
    SkillLevel nvarchar(50) not null,
    primary key(CandidateID,SkillID)

    SkillID    int    IDENTITY(1,1) PRIMARY KEY,
    SkillName    nvarchar(50) NOT NULL,

  • Was you CandidatesSkill was mapped correctly to a Skill and a Candidate?

    You should first link your candidateSkill like so:

    CandidatesSkills candidateSkills  = new CandidatesSkills ;





    Note that the candidateSkills  will be automaticlly added to the candidateSkill table since it's was linked to an Context's object.


    i hope it solves your problem.

  • Hello,

    Thank you for posting.

    Entity Framework needs to know about the FK constraint before it decide which table to insert into first. I suggest you can modify SSDL file to declare the FK constraint.

    Please feel free to let us know how it goes.
