Argument type 'Umbraco.Web.Models.RenderModel' is not assignable to model type 'Umbraco.Web.Models.RenderModel<model>'

Umbraco 7.4.1

Hey I am sitting with a strange problem. And I'm new to this SurfaceController...

Argument type 'Umbraco.Web.Models.RenderModel' is not assignable to model type 'Umbraco.Web.Models.RenderModel<MovieRating.Models.FilmModel>'

enter image description here

  public class RatingController : SurfaceController
  {    
    [ChildActionOnly]
    public ActionResult GetRatingForm(int filmId)
    {  
        if (Members.IsLoggedIn())
        {
            var umbracoContext = UmbracoContext.ContentCache.GetById(filmId);
            var model = new FilmModel(umbracoContext);
            return PartialView("~/views/Partials/_RatingForm.cshtml", new RenderModel(model));
        }
        return null;
    }
 }

Suspect the problem is with your _RatingForm.cshtml View - I'm new to Umbraco and had the SAME problem yesterday...

_RatingForm.cshtml has this as inherits. Can you see what it could be?
```
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage<MovieRating.Models.FilmModel>
```

How are you calling the GetRatingForm controller?

Like this

 @inherits Umbraco.Web.Mvc.UmbracoTemplatePage<MovieRating.Models.FilmOverviewModel>
  ...
 @foreach (var film in Model.Content.Films)
 {
  ...
  @Html.Action("GetRatingForm", "Rating", new { filmId = film.Id })
  ...
 }

You've passed new RenderModel(model)) in your controller when it should be model...

It does not remove the erroris not assignable to model type. And I 've also tried. The website works. So I do not know what is happening or why...

Hello,

from your controller method return the model of type FilmModel directly:
```
return PartialView("~/views/Partials/_RatingForm.cshtml", model);
```
Then in your partial view, inherits the "FilmModel" instead of "@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
```
@model FilmModel
```
To access any property value do:
```
@Model.PropertyName
```

Ronish Potiah Thank you very much :)

And thank you Toppers

FilmModel is of type IPublishedContent ( obvious? )
