CRUD in MVC repository

Question

I have created a repository data layer in my MVC web application, and want to use it for my CRUD methods. But I came to think of situations where I want to do something like:

If record does not exist
   create record
else
   update record

But how does this fit into CRUD? Is this two-in-one operation logic supposed to be kept in the controller?

Answer 1

I think the repository should take care of that, the controller should be as light as possible:

At repository level:

public bool CreateUpdate(Type model)
{
    var record = db.FirstOrDefault(x=> x.Id == model.Id);
    if(record == null)
    {
        Create(model);
    }
    else
    {
        Update(model);
    }
}

public bool Create(Type model)
{
    //create logic here
}

public bool Update(Type model)
{
    //update logic here
}
