Build The Trips Log App For This Project You Will Build A Data Drive ✓ Solved
Build the Trips Log app For this project, you will build a data-driven web app that uses view models to pass data from controllers to views, the ViewBag object to pass data from views to the layout, and TempData to persist data between requests. Specifications ï‚· When the app starts, it should display trip data and an Add Trip link. ï‚· The layout for this web app should display a banner at the top of the page, and a subhead below it. However, the subhead should only display if there’s text in the ViewData property for it. ï‚· When the user clicks the Add Trip link, a three page data entry process should start. ï‚· On the first page, the user should enter data about the trip destination and dates.
The Accommodations field on this page should be optional, and the rest should be required. ï‚· The second page should only display if the user entered a value for the Accommodations field on the first page. On this page, the user should enter data about the accommodations. The accommodation value the user entered should display in the subhead, and the fields should be optional. ï‚· On the third page, the user should enter data about things to do on their trip. The destination the user entered on the first page should display in the subhead, and the fields should be optional. ï‚· When the user clicks the Next button on the first or second page, the web app should save the data posted from the page in TempData.
Use this data to get the user entries to display in the subheads as needed. ï‚· When the user clicks the Save button on the third page, the user will see the Home page displaying with a temporary message that the trip has been added with the details of the trip listed below. ï‚· When the user clicks the Cancel button on any of the Add pages, the data in TempData should be cleared and the Home page should display. You can use this statement to clear the data: TempData.Clear();

Building the Trips Log App
Introduction
In today’s data-centric world, the notion of efficiently managing travel experiences is becoming increasingly vital. A well-structured web application is a great solution for users who wish to log their trips, while also providing them with friendly interfaces and responsive data handling capabilities. In this project, we are tasked with creating a data-driven web application called the "Trips Log App". The application must enable users to log their trips while providing smooth navigation and data entry over multiple pages. Furthermore, it also employs the use of MVC (Model-View-Controller) architecture principles by utilizing View Models, TempData, and ViewBag for data manipulation and display.
Application Specifications
The Trips Log App is designed to meet specific user requirements based on an outlined specification. The following points detail the core functionality and layout aspects of the application:
1. Home Page: When the application starts, users should observe a display of all previous trips logged along with an "Add Trip" link to initiate the trip entry process.
2. Layout Design: The application layout features a header banner at the top and a subheader directly beneath it. The subheader functions conditionally, only displaying text if there is existing input from the property ViewData.
3. Multi-Step Data Entry:
- Step 1: On clicking "Add Trip", users are directed to the first page where they enter trip details such as destination, and trip dates. The accommodation field is optional while all other fields are required.
- Step 2: The second page is accessible only if the accommodation details are filled in step one. Here, users can input data about accommodations, with all fields being optional.
- Step 3: The final page requires users to input activities or things to do during their trip. The destination from the first page appears in the subheader to provide context; again, fields are optional.
4. Data Handling and Navigation:
- The application uses TempData to persist data temporarily between requests. When users click "Next" on steps one or two, entered data is stored in TempData for retrieval on the following page.
- When completing the final step and clicking "Save", users are returned to the Home page with a temporary confirmation message about their newly logged trip.
- Clicking "Cancel" on any page results in resetting TempData, redirecting them immediately back to the Home page.
Implementation Overview
To practically implement the above specifications, the development process encompasses several critical steps. Each component needs to be adequately set up to accommodate user input and interface requirements.
1. Setting Up the Project
- Begin by creating a new ASP.NET MVC project using Visual Studio.
- Set up necessary folders for Models, Views, Controllers, and other assets like CSS or JavaScript.
2. Data Models
To maintain the trip information, create a `Trip` model that encapsulates all relevant properties:
```csharp
public class Trip
{
public string Destination { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public string Accommodations { get; set; }
public List
}
```
3. Controllers
Create a `TripsController` to handle the user actions:
```csharp
public class TripsController : Controller
{
public ActionResult Index()
{
// Retrieve and display all trips.
}
public ActionResult AddTripStep1()
{
return View();
}
[HttpPost]
public ActionResult AddTripStep1(Trip trip)
{
if (ModelState.IsValid)
{
TempData["TripData"] = trip;
return RedirectToAction("AddTripStep2");
}
return View(trip);
}
public ActionResult AddTripStep2()
{
var trip = TempData["TripData"] as Trip;
ViewBag.Accommodations = trip?.Accommodations;
return View();
}
[HttpPost]
public ActionResult AddTripStep2(string accommodations)
{
var trip = TempData["TripData"] as Trip;
trip.Accommodations = accommodations;
TempData["TripData"] = trip;
return RedirectToAction("AddTripStep3");
}
public ActionResult AddTripStep3()
{
return View();
}
[HttpPost]
public ActionResult AddTripStep3(List
{
var trip = TempData["TripData"] as Trip;
trip.Activities = activities;
// Save the trip to the database, notify user of success
TempData["Message"] = "Trip added successfully!";
TempData.Clear();
return RedirectToAction("Index");
}
public ActionResult Cancel()
{
TempData.Clear();
return RedirectToAction("Index");
}
}
```
4. Views
Use Razor views to create UI for each step.
- Index View (Home Page): List all trips and an "Add Trip" link.
- AddTripStep1 View: Form for collecting destination and dates.
- AddTripStep2 View: Conditional form for accommodations.
- AddTripStep3 View: Form for activities.
5. Conditional Display of Subheader
To implement the dynamic display of subheader texts based on the ViewData property, you can use Razor syntax:
```html
@if (ViewData["SubHeader"] != null)
{
@ViewData["SubHeader"]
}
```
Conclusion
The Trips Log App is designed to streamline the process of logging travel experiences, featuring a multifaceted data entry process, user-friendly navigation, and effective data handling through MVC principles. This application effectively integrates page transitions through TempData for persisting user data, with a clean user interface to enhance user experience.
