Save a Value outside of Dropdownlist EF6 - asp.net-mvc-5

Question

I wish to save an id field called AssetAssignmentID the value of "2" everytime a new modelname is saved.
I was looking to see if i could do the following;
That was if the Modelname was not null, then save both the ModelName and AssetAssignmentID to = "2"
public ActionResult Create(ClinicalAsset clinicalAssets)
{
try
{
if (ModelState.IsValid)
{
if (clinicalAssets.ModelName != null)
{
clinicalAssets.ModelName = clinicalAssets.ModelName;
clinicalAssets.AssetAssignmentID = "2";
}
db.ClinicalAssets.Add(clinicalAssets);
db.SaveChanges();
return RedirectToAction("Details", "ClinicalAssets", new { ClinicalAssetID = clinicalAssets.ClinicalAssetID });
}
}
However it complains that an object reference is required for non-static field.
If I make reference to the AssetAssignmentID in the ClinicalAsset Model I cannot convert type int to Model.
The populated dropdownlist
private void PopulateModelDropDownList(object selectedModel = null)
{
var ModelsQuery = from d in db.Models.Where(x => x.AssetAssignmentID == 2) orderby d.ModelName select d;
ViewBag.ModelDropDown = new SelectList(ModelsQuery, "ModelID", "ModelName", selectedModel);
}
I would expect that every time a new ModelName is submitted to the database the AssetAssignmentID would always equal the value of two.
edit
I have also tried
var clinicalAsset = new ClinicalAsset { AssetAssignmentID = 2 };
if (clinicalAssets.ModelName != null)
{
clinicalAssets.ModelName = clinicalAssets.ModelName;
}
db.ClinicalAssets.Add(clinicalAsset);
db.SaveChanges();
return RedirectToAction("Details", "ClinicalAssets", new { ClinicalAssetID = clinicalAssets.ClinicalAssetID });
but the error is: Cannot implicitly convert type 'int' to 'Assets.Models.Model'

UPDATE
I now have the AssignmentID saving as 2, but it creates a new entry in the database rather than assigning two values to the same field

Answer 1

Thanks to A.Nadjar & Train
Although i didn't need a Viewmodel the solution was to save the data with THE 1 TO MANY relationship saving first, followed by the main entity last, and also ensure the foreign key was created for the AssetAssignmentID in the model.
Code:
if (ModelState.IsValid)
{
var newClinicalAsset = new ClinicalAsset();
var NewModel = new Model();
if (clinicalAssetVM.AssetTypeID == 0)
{
}
else
{
newClinicalAsset.AssetTypeID = clinicalAssetVM.AssetTypeID;
}
if (clinicalAssetVM.ModelName != null)
{
NewModel.ModelAssetAssignmentID = clinicalAssetVM.AssetAssignmentID.AssetAssignmentID;
NewModel.ModelName = clinicalAssetVM.ModelName.ModelName;
db.Models.Add(NewModel);
db.SaveChanges();
}
newClinicalAsset = new ClinicalAsset { ModelID = NewModel.ModelID, AssetTypeID = newClinicalAsset.AssetTypeID};
db.ClinicalAssets.Add(newClinicalAsset);
db.SaveChanges();
return RedirectToAction("Details", "ClinicalAssets", new { ClinicalAssetID = clinicalAssetVM.ClinicalAssetID });
}
