c# - Adding where clause to index method of scaffolded controller ASP.NET MVC with EF -

-

I have a project model and an actor model - a project can include many artists for my actor controller Trying to modify lofty scenes so that an ID can be sent to the index and to make the method so that only the actor (index) can be added for the current project or (create)

Here I start for the index method and I'm not sure where to add the clause. N.B. I am passing in the id as the parameter of the index from the URL.

(Sorry, this is a basic question, I am goggling, but no answer can be found).

Thank you! 

  Private JustSpecItAppContext db = New JustSpecItAppContext (); // GET: Actors 1 Public Performance Index () {Return View (db.Actors.ToList ()); }

try this: - 

  public actions Index (int award id) {return view (db.actors.firstor default (a => an id == actor id)); }

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
