Question

I am trying to pass an object of model class for edit but receing this error “The model item passed into the dictionary is of type ‘System.Collections.Generic.List`1[MvcApplication1.Models.ResturantReviews]’, but this dictionary requires a model item of type ‘MvcApplication1.Models.ResturantReviews’.”

Kindly guide me where I am wrong, here is my code:

My Model class:

namespace MvcApplication1.Models{
public class ResturantReviews
{

        public int ReviewId { get; set; }
        public int Rating { get; set; }
        public string ReviewBody { get; set; }
        public Resturant Resturant { get; set; }

}

}

My Action code:

public ActionResult Edit(int Id)
    {
        //var review = FoodDB.review;
        ResturantReviews obj = new ResturantReviews {
          ReviewId = 2,
            Rating = 9,
            ReviewBody = "Test Sarina is a good resturant for continantal food",
            Resturant = new Resturant
            {
                ResturantId = 1,
                ResturantAddress = "Commercial area",
                ResturantName = "Sarina Hotel"

            }
        };



        return View(obj);
    }

My code in View:

@model MvcApplication1.Models.ResturantReviews

@{
    ViewBag.Title = "Edit";
}

<h2>Edit</h2>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>ResturantReviews</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.ReviewId)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.ReviewId)
            @Html.ValidationMessageFor(model => model.ReviewId)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Rating)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Rating)
            @Html.ValidationMessageFor(model => model.Rating)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.ReviewBody)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.ReviewBody)
            @Html.ValidationMessageFor(model => model.ReviewBody)
        </div>

        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

Answer 1

The Edit controller action (as shown in your question) passes a single instance of ResturantReviews and the view is strongly typed to @model ResturantReviews so this should not throw an exception. The code seems correct as is.

So you could try narrowing down by simplifying at maximum:

public ActionResult Edit(int Id)
{
    var model = new ResturantReviews();
    return View(model);
}

and the Edit.cshtml view:

@model ResturantReviews
@Html.BeginForm()
{
    <p>
        <input type="submit" value="Save" />
    </p>    
}

This should work 100%. Then you could start adding functionality.
