5 star rating in mail using c mvc

Here is an example of how to implement a 5-star rating system using C# MVC:

Model

Create a new model class Rating to store the rating data:

public class Rating
{
    public int Id { get; set; }
    public int MovieId { get; set; }
    public int RatingValue { get; set; } // 1-5
    public string Comment { get; set; }
    public DateTime DateAdded { get; set; }
}

Controller

Create a new controller class RatingsController to handle the rating data:

public class RatingsController : Controller
{
    private readonly DbContext _dbContext;

    public RatingsController(DbContext dbContext)
    {
        _dbContext = dbContext;
    }

    // GET: Ratings
    public ActionResult Index()
    {
        var ratings = _dbContext.Ratings.ToList();
        return View(ratings);
    }

    // POST: Ratings
    [HttpPost]
    public ActionResult Create(Rating rating)
    {
        if (ModelState.IsValid)
        {
            _dbContext.Ratings.Add(rating);
            _dbContext.SaveChanges();
            return RedirectToAction("Index");
        }
        return View(rating);
    }

    // GET: Ratings/Edit/5
    public ActionResult Edit(int id)
    {
        var rating = _dbContext.Ratings.Find(id);
        return View(rating);
    }

    // POST: Ratings/Edit/5
    [HttpPost]
    public ActionResult Edit(Rating rating)
    {
        if (ModelState.IsValid)
        {
            _dbContext.Entry(rating).State = EntityState.Modified;
            _dbContext.SaveChanges();
            return RedirectToAction("Index");
        }
        return View(rating);
    }

    // GET: Ratings/Delete/5
    public ActionResult Delete(int id)
    {
        var rating = _dbContext.Ratings.Find(id);
        return View(rating);
    }

    // POST: Ratings/Delete/5
    [HttpPost, ActionName("Delete")]
    public ActionResult DeleteConfirmed(int id)
    {
        var rating = _dbContext.Ratings.Find(id);
        _dbContext.Ratings.Remove(rating);
        _dbContext.SaveChanges();
        return RedirectToAction("Index");
    }
}

View

Create a new view Index.cshtml to display the ratings:

@model IEnumerable<Rating>

<h2>Ratings</h2>

<table>
    <tr>
        <th>Movie Title</th>
        <th>Rating Value</th>
        <th>Comment</th>
        <th>Date Added</th>
        <th></th>
    </tr>

@foreach (var item in Model)
{
    <tr>
        <td>@item.Movie.Title</td>
        <td>@item.RatingValue</td>
        <td>@item.Comment</td>
        <td>@item.DateAdded.ToString("yyyy-MM-dd")</td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id = item.Id }) |
            @Html.ActionLink("Delete", "Delete", new { id = item.Id })
        </td>
    </tr>
}

</table>

<h2>Add Rating</h2>

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Rating</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })

        <div class="form-group">
            @Html.LabelFor(model => model.MovieId, "Movie", htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.DropDownList("MovieId", null, htmlAttributes: new { @class = "form-control" })
                @Html.ValidationMessageFor(model => model.MovieId, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.RatingValue, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.RatingValue, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.RatingValue, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.Comment, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Comment, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Comment, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>
    </div>
}

JavaScript

Add the following JavaScript code to the view to handle the rating submission:

$(document).ready(function () {
    $('#RatingValue').rating({
        size: 'xs',
        starCaption: 'Rating: {0}/5',
        starEmpty: '☆',
        starHalf: '★',
        starFull: '★'
    });

    $('#RatingForm').submit(function (e) {
        e.preventDefault();
        var ratingValue = $('#RatingValue').val();
        var comment = $('#Comment').val();
        $.ajax({
            type: 'POST',
            url: '@Url.Action("Create", "Ratings")',
            data: { ratingValue: ratingValue, comment: comment },
            success: function (data) {
                alert('Rating submitted successfully!');
                window.location.href = '@Url.Action("Index", "Ratings")';
            }
        });
    });
});

This code uses the jQuery Rating plugin to create a 5-star rating system. When the user submits the form, it sends a POST request to the Create action method in the RatingsController to create a new rating.

Note: This is just a basic example and you may want to add additional validation, error handling, and security measures to your application.
