In this part we will be finishing up the functionality to assign a book to a customer and returning the book.
Source Code: https://github.com/alexcalingasan/LibraryManagement
Now let’s update our View for Create and Edit page of BorrowHistory.
Copy and paste this for your BorrowHistory create view.
@model LibraryManagement.Models.Book
@{
ViewBag.Title = "Create";
}
<h2>Create</h2>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Book</h4>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.Title, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Title, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Title, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.SerialNumber, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.SerialNumber, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.SerialNumber, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Author, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Author, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Author, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Publisher, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Publisher, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Publisher, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
</div>
</div>
</div>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
Then change your BorrowHistories Edit view code to this.
@model LibraryManagement.Models.Book
@{
ViewBag.Title = "Edit";
}
<h2>Edit</h2>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Book</h4>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
@Html.HiddenFor(model => model.BookId)
<div class="form-group">
@Html.LabelFor(model => model.Title, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Title, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Title, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.SerialNumber, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.SerialNumber, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.SerialNumber, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Author, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Author, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Author, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Publisher, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Publisher, new { htmlAttributes = new { @class = "form-control" } })
@Html.ValidationMessageFor(model => model.Publisher, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
</div>
</div>
</div>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
Then change you BorrowHistories Controller to this.
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;
using LibraryManagement.Models;
namespace LibraryManagement.Controllers
{
public class BorrowHistoriesController : Controller
{
private ApplicationDbContext db = new ApplicationDbContext();
// GET: BorrowHistories/Create
public ActionResult Create(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
var book = db.Books.Find(id);
if (book == null)
{
return HttpNotFound();
}
var borrowHistory = new BorrowHistory { BookId = book.BookId, BorrowDate = DateTime.Now, Book = book };
ViewBag.CustomerId = new SelectList(db.Customers, "CustomerId", "Name");
return View(borrowHistory);
}
// POST: BorrowHistories/Create
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
// more details see https://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "BorrowHistoryId,BookId,CustomerId,BorrowDate,ReturnDate")] BorrowHistory borrowHistory)
{
if (ModelState.IsValid)
{
db.BorrowHistories.Add(borrowHistory);
db.SaveChanges();
return RedirectToAction("Index", "Books");
}
ViewBag.CustomerId = new SelectList(db.Customers, "CustomerId", "Name", borrowHistory.CustomerId);
borrowHistory.Book = db.Books.Find(borrowHistory.BookId);
return View(borrowHistory);
}
// GET: BorrowHistories/Edit/5
public ActionResult Edit(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
BorrowHistory borrowHistory = db.BorrowHistories
.Include(b => b.Book)
.Include(c => c.Customer)
.Where(b => b.BookId == id && b.ReturnDate == null)
.FirstOrDefault();
if (borrowHistory == null)
{
return HttpNotFound();
}
return View(borrowHistory);
}
// POST: BorrowHistories/Edit/5
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
// more details see https://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include = "BorrowHistoryId,BookId,CustomerId,BorrowDate,ReturnDate")] BorrowHistory borrowHistory)
{
if (ModelState.IsValid)
{
var borrowHistoryItem = db.BorrowHistories.Include(i => i.Book)
.FirstOrDefault(i => i.BorrowHistoryId == borrowHistory.BorrowHistoryId);
if (borrowHistoryItem == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
borrowHistoryItem.ReturnDate = DateTime.Now;
db.SaveChanges();
return RedirectToAction("Index", "Books");
}
return View(borrowHistory);
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
db.Dispose();
}
base.Dispose(disposing);
}
}
}
Now go and run your project and you should have now functionality to borrow and return a book.
