Implementing the Profile Feature

Setting Up the Registration Form

The first step in implementing the profile feature is ensuring that the registration form captures all necessary user details. This includes fields like first name, last name, date of birth, and password.

Navigate to register.html:
- This file contains the form responsible for user registration.
Copy the Registration Form:
- Duplicate the form code to be used in the profile page.
Paste the Form into profile.html:
- Open profile.html and replace the existing content with the copied form.
Modify Form Attributes:
- Change the form action to point to the profile endpoint.
- Update the heading to “Profile”.
- Change the submission button text to “Update Profile”.

Sample Registration Form Code


&lt;!-- profile.html --&gt;
&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;Profile&lt;/title&gt;
    &lt;!-- Include necessary CSS files --&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h2&gt;Profile&lt;/h2&gt;
    &lt;form action="/profile" method="post"&gt;
        &lt;label for="firstName"&gt;First Name:&lt;/label&gt;
        &lt;input type="text" id="firstName" name="firstName" value="${account.firstName}" required&gt;&lt;br&gt;&lt;br&gt;
        
        &lt;label for="lastName"&gt;Last Name:&lt;/label&gt;
        &lt;input type="text" id="lastName" name="lastName" value="${account.lastName}" required&gt;&lt;br&gt;&lt;br&gt;
        
        &lt;label for="dob"&gt;Date of Birth:&lt;/label&gt;
        &lt;input type="date" id="dob" name="dob" value="${account.dateOfBirth}"&gt;&lt;br&gt;&lt;br&gt;
        
        &lt;label for="password"&gt;Password:&lt;/label&gt;
        &lt;input type="password" id="password" name="password" required&gt;&lt;br&gt;&lt;br&gt;
        
        &lt;button type="submit"&gt;Update Profile&lt;/button&gt;
    &lt;/form&gt;
&lt;/body&gt;
&lt;/html&gt;

<!DOCTYPE html>

<html>

<head>

<title>Profile</title>

</head>

<body>

<h2>Profile</h2>

<label for="firstName">First Name:</label>

<label for="dob">Date of Birth:</label>

<label for="password">Password:</label>

<button type="submit">Update Profile</button>

</form>

</body>

</html>

Modifying the Profile Page

After setting up the registration form within profile.html, you need to make several adjustments to ensure it functions correctly.

Change Form Action:
- Update the form’s action attribute to /profile, which is the endpoint responsible for handling profile updates.
Update Headings and Buttons:
- Change the heading to “Profile”.
- Modify the submit button text to “Update Profile”.
Finalize the Profile Page Layout:
- Ensure that the form fields are pre-populated with the user’s existing information.
- Add placeholders or default values where necessary.

Updating the Account Controller

The Account Controller manages user-related operations, including loading and updating user profiles.

Steps to Update AccountController.java:

Add Profile Endpoint:
- Create a GET endpoint to load the profile page.
Ensure Authentication:
- Use annotations to ensure that only authenticated users can access the profile page.
Fetch User Data:
- Retrieve the authenticated user’s data to pre-populate the form.
Handle Profile Updates:
- Create a POST endpoint to handle form submissions and update user information.

Sample Controller Code


// AccountController.java
package org.studyeasy.SpringBlog.controller;

import org.studyeasy.SpringBlog.models.Account;
import org.studyeasy.SpringBlog.services.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;

import java.security.Principal;
import java.util.Optional;

@Controller
public class AccountController {

    @Autowired
    private AccountService accountService;

    @GetMapping("/profile")
    public String getProfile(Model model, Principal principal) {
        if (principal != null) {
            String authUser = principal.getName();
            Optional<Account> optionalAccount = accountService.findByEmail(authUser);
            if (optionalAccount.isPresent()) {
                Account account = optionalAccount.get();
                model.addAttribute("account", account);
                model.addAttribute("photo", account.getPhotoURL());
                return "account_views/profile";
            }
        }
        return "redirect:/?error";
    }

    @PostMapping("/profile")
    public String updateProfile(Account account, Principal principal) {
        if (principal != null) {
            String authUser = principal.getName();
            accountService.updateAccount(authUser, account);
            return "redirect:/profile?success";
        }
        return "redirect:/?error";
    }
}

// AccountController.java

package org.studyeasy.SpringBlog.controller;

import org.studyeasy.SpringBlog.models.Account;

import org.studyeasy.SpringBlog.services.AccountService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.PostMapping;

import java.security.Principal;

import java.util.Optional;

@Controller

public class AccountController {

@Autowired

private AccountService accountService;

@GetMapping("/profile")

public String getProfile(Model model, Principal principal) {

if (principal != null) {

String authUser = principal.getName();

Optional<Account> optionalAccount = accountService.findByEmail(authUser);

if (optionalAccount.isPresent()) {

Account account = optionalAccount.get();

model.addAttribute("account", account);

model.addAttribute("photo", account.getPhotoURL());

return "account_views/profile";

}

return "redirect:/?error";

}

@PostMapping("/profile")

public String updateProfile(Account account, Principal principal) {

if (principal != null) {

String authUser = principal.getName();

accountService.updateAccount(authUser, account);

return "redirect:/profile?success";

}

return "redirect:/?error";

}

Adding Profile Pictures

Enhancing the profile feature with profile pictures makes the user experience more engaging. Here’s how to implement this functionality.

Modify the Profile Form:
- Add an input field for uploading images.
Handle Image Uploads in the Controller:
- Process and store the uploaded images.
Display the Profile Picture:
- Update profile.html to show the user’s profile picture.

Sample Code for Adding Profile Pictures


&lt;!-- profile.html --&gt;
&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;Profile&lt;/title&gt;
    &lt;!-- Include necessary CSS files --&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h2&gt;Profile&lt;/h2&gt;
    &lt;form action="/profile" method="post" enctype="multipart/form-data"&gt;
        &lt;!-- Existing form fields --&gt;
        
        &lt;label for="photo"&gt;Profile Picture:&lt;/label&gt;
        &lt;input type="file" id="photo" name="photo"&gt;&lt;br&gt;&lt;br&gt;
        
        &lt;button type="submit"&gt;Update Profile&lt;/button&gt;
    &lt;/form&gt;
    
    &lt;!-- Display Profile Picture --&gt;
    &lt;img src="/images/${photo}" alt="Avatar" class="rounded" style="padding: 10px; float: left; width: 150px;"&gt;
&lt;/body&gt;
&lt;/html&gt;

<!DOCTYPE html>

<html>

<head>

<title>Profile</title>

</head>

<body>

<h2>Profile</h2>

<label for="photo">Profile Picture:</label>

<button type="submit">Update Profile</button>

</form>

</body>

</html>

Understanding the Code

Controller Code Explained

The AccountController manages the retrieval and updating of user profiles. Here’s a breakdown of its functionalities:

@GetMapping("/profile"):
- Loads the profile page.
- Retrieves the authenticated user’s information.
- Adds user data and photo URL to the model for rendering in the view.
@PostMapping("/profile"):
- Handles form submissions for profile updates.
- Calls the AccountService to update user information.
- Redirects the user based on the success or failure of the operation.

Profile Form Code

The profile form in profile.html allows users to view and edit their personal information. Key elements include:

Pre-populated Fields:
- The form fields are filled with the user’s existing data using Thymeleaf expressions like ${account.firstName}.
File Upload for Profile Pictures:
- An input of type file allows users to upload a new profile picture.
Styling the Form:
- CSS classes and inline styles ensure the form is user-friendly and visually appealing.

Styling the Profile Page

Styling enhances the user interface, making the profile page intuitive and attractive.

Sample CSS for Profile Picture


/* style.css */
.rounded {
    border-radius: 50%;
}

img {
    padding: 10px;
    float: left;
    width: 150px;
    height: 150px;
