User Management Fixes - Complete

🎯 Issues Fixed

1. Edit Button Not Working ❌ → ✅

Problem: The edit button wasn't loading user data because:

• Missing GET endpoint for single user (/api/admin/users/:id)
• JavaScript was passing user ID incorrectly (without quotes)

Solution:

• Added GET endpoint to fetch single user by ID
• Fixed JavaScript to properly quote user IDs in onclick handlers

2. User Creation Not Saving Data ❌ → ✅

Problem: When creating users:

• name field was not being saved to database
• role field was being sent as role_id but database uses role
• Username and password were not properly validated

Solution:

• Updated POST endpoint to save name field
• Changed backend to use role instead of role_id
• Added proper validation for all required fields
• Check for duplicate username AND email

3. Password Not Stored Securely ❌ → ✅

Problem:

• Password hashing was working, but no dedicated password change endpoint
• Password updates mixed with user updates

Solution:

• Added dedicated PUT /api/admin/users/:id/password endpoint
• Ensured bcrypt with 10 rounds for all password operations
• Separated password changes from user profile updates

4. Database Storage Issues ❌ → ✅

Problem:

• Mismatched column names (role_id vs role)
• Missing name field in queries
• Inconsistent field naming (passwordneverexpires vs password_never_expires)

Solution:

• Standardized to use database column names: role, name, passwordneverexpires
• Updated all queries to include proper fields
• Ensured data is reading and updating correctly

📝 Changes Made

Backend Changes: /backend/routes/users.js

1. Added GET Single User Endpoint

// Get single user by ID
router.get("/:id", async (req, res) => {
  const { id } = req.params;
  const result = await query(`
    SELECT 
      u.id, u.username, u.email, u.name, u.role, u.isactive, 
      u.last_login, u.createdat, u.passwordneverexpires, u.role_id
    FROM adminusers u
    WHERE u.id = $1
  `, [id]);
  // ... returns user data
});

2. Fixed Create User Endpoint

// Create new user - Now saves name, role, and properly hashes password
router.post("/", async (req, res) => {
  const { name, username, email, password, role, passwordneverexpires } = req.body;
  
  // Validate required fields
  if (!username || !email || !password || !role) {
    return res.status(400).json({
      success: false,
      message: "Name, username, email, password, and role are required",
    });
  }

  // Check for duplicates (email OR username)
  const existing = await query(
    "SELECT id FROM adminusers WHERE email = $1 OR username = $2",
    [email, username]
  );

  // Hash password with bcrypt (10 rounds)
  const hashedPassword = await bcrypt.hash(password, 10);

  // Insert with name and role fields
  const result = await query(`
    INSERT INTO adminusers (
      id, name, username, email, passwordhash, role, 
      passwordneverexpires, password_expires_at, 
      isactive, created_by, createdat, lastpasswordchange
    ) VALUES (
      'user-' || gen_random_uuid()::text,
      $1, $2, $3, $4, $5, $6, $7, true, $8, NOW(), NOW()
    )
    RETURNING id, name, username, email, role, isactive, createdat, passwordneverexpires
  `, [name || username, username, email, hashedPassword, role, ...]);
  // ...
});

3. Fixed Update User Endpoint

// Update user - Now handles name, role, and optional password
router.put("/:id", async (req, res) => {
  const { name, username, email, role, isactive, passwordneverexpires, password } = req.body;

  // Build dynamic update query
  if (name !== undefined) {
    updates.push(`name = $${paramCount++}`);
    values.push(name);
  }
  if (role !== undefined) {
    updates.push(`role = $${paramCount++}`);
    values.push(role);
  }

  // Handle optional password update
  if (password !== undefined && password !== '') {
    if (password.length < 8) {
      return res.status(400).json({
        success: false,
        message: "Password must be at least 8 characters long",
      });
    }
    const hashedPassword = await bcrypt.hash(password, 10);
    updates.push(`passwordhash = $${paramCount++}`);
    values.push(hashedPassword);
    updates.push(`lastpasswordchange = NOW()`);
  }
  // ...
});

4. Added Password Change Endpoint

// Change user password (PUT endpoint for password modal)
router.put("/:id/password", async (req, res) => {
  const { password } = req.body;

  if (!password || password.length < 8) {
    return res.status(400).json({
      success: false,
      message: "Password must be at least 8 characters long",
    });
  }

  // Hash new password with bcrypt (10 rounds)
  const hashedPassword = await bcrypt.hash(password, 10);

  // Update password with expiry calculation
  await query(`
    UPDATE adminusers
    SET passwordhash = $1,
        password_expires_at = $2,
        lastpasswordchange = NOW(),
        updatedat = NOW()
    WHERE id = $3
  `, [hashedPassword, passwordExpiresAt, id]);
  // ...
});

Frontend Changes: /website/admin/js/users.js

Fixed Edit Button Click Handlers

// Before: onclick="editUser(${u.id})" - incorrect, treats ID as number
// After:  onclick="editUser('${escapeHtml(u.id)}')" - correct, ID is string

<button class="btn btn-sm btn-info" onclick="editUser('${escapeHtml(u.id)}')" title="Edit User">
  <i class="bi bi-pencil"></i>
</button>
<button class="btn btn-sm btn-warning" onclick="showChangePassword('${escapeHtml(u.id)}', '${escapeHtml(u.name)}')" title="Change Password">
  <i class="bi bi-key"></i>
</button>
<button class="btn btn-sm btn-danger" onclick="deleteUser('${escapeHtml(u.id)}', '${escapeHtml(u.name)}')" title="Delete User">
  <i class="bi bi-trash"></i>
</button>
