Template Fixes Summary

Overview

This document summarizes the template fixes applied to the TankStopp application after migrating from HTML templates to the a-h/templ system. These fixes address various issues found during testing and review of the dashboard and settings pages.

Issues Fixed

1. Critical: Duplicate Input Fields in Login Form

Problem: Input fields were appearing twice on the login page and all other forms.

Root Cause: The FormGroup component had { children... } appearing twice:

// WRONG - children rendered twice
templ FormGroup(label, hint string) {
    <div class="mb-3">
        if label != "" {
            <label class="form-label">
                { children... }  // ❌ First rendering
                { label }
            </label>
        }
        { children... }  // ❌ Second rendering (duplicate!)
    </div>
}

Fix: Removed the duplicate { children... } from inside the label:

// CORRECT - children rendered once
templ FormGroup(label, hint string) {
    <div class="mb-3">
        if label != "" {
            <label class="form-label">
                { label }
            </label>
        }
        { children... }  // ✅ Single rendering
    </div>
}

Impact: Fixed duplicate input fields across all forms (login, register, add/edit fuel stops, vehicles, settings).

2. Dashboard Template Improvements

Missing JavaScript Integration

Problem: Dashboard filters and confirmation dialogs weren't working. Fix: Added @DashboardScript() to the dashboard template to include the JavaScript functionality.

Location Field Consistency

Problem: Inconsistent use of location fields in the fuel stops table. Fix: Ensured consistent use of stop.Location field based on the actual model structure.

3. Settings Template Enhancements

Missing Email Field

Problem: Profile settings form was missing the email field. Fix: Added email input field to the profile settings section:

@components.FormGroup("Email", "Your email address") {
    @components.Input("email", "email", "Enter email", user.Email, true)
}

Improved Sidebar Information

Problem: Sidebar showed hardcoded "0" values and limited information. Fix: Enhanced the account summary with:

• User's email address
• Account status badge
• Better layout for quick actions with icons

Quick Actions Icon Alignment

Problem: Icons in quick actions were not properly aligned. Fix: Added proper flex layout and spacing:

<a href="/add" class="list-group-item list-group-item-action d-flex align-items-center">
    <span class="me-2">@components.Icon("plus", 24)</span>
    Add Fuel Stop
</a>

4. Icon Component Enhancements

Problem: Several icons were missing from the icon component, causing broken UI elements.

Added Icons:

• database - For data management section
• download - For export functionality
• upload - For import functionality
• zap - For quick actions section
• search - For search functionality
• dots-vertical - For dropdown menus

Example:

case "database":
    <ellipse cx="12" cy="5" rx="9" ry="3"/>
    <path d="M3 5v14a9 3 0 0 0 18 0v-14"/>
    <path d="M3 12a9 3 0 0 0 18 0"/>
