/** @odoo-module **/

import publicWidget from "@web/legacy/js/public/public_widget";
// import ajax from 'web.ajax';
import { rpc } from "@web/core/network/rpc";

publicWidget.registry.AutovoyageServiceVehicles = publicWidget.Widget.extend({
selector: '.s_services_vehicles',

start: function () {
    console.log('Fetching vehicles...');
    this._fetchVehicles();
    return this._super.apply(this, arguments);
},

_fetchVehicles:async function () {
    // Fetch vehicle data from the server
    await rpc('/autovoyage/get_vehicles', {}).then((vehicles) => {
        console.log('Vehicles fetched:', vehicles);
        this._renderVehicles(vehicles);
    }).catch((error) => {
        console.error('Error fetching vehicles:', error);
    });
},

_renderVehicles: function (vehicles) {
    const container = this.$el.find('.d-flex'); // Find the container for cards
    container.empty(); // Clear any existing content

    vehicles.forEach(vehicle => {
        const cardHtml = `
            <div class="card" style="width: 18rem;">
                <div class="card-body">
                    <h5 class="card-title">${vehicle.name}</h5>
                    <p class="card-text mb-1"><strong>Model:</strong> ${vehicle.vehicle_model || 'N/A'}</p>
                    <p class="card-text mb-1"><strong>Service Provider:</strong> ${vehicle.service_provider || 'N/A'}</p>
                    <p class="card-text mb-1"><strong>Fuel Type:</strong> ${vehicle.vehicle_fule_type || 'N/A'}</p>
                    <p class="card-text mb-2"><strong>Rent/Day:</strong> ₹${vehicle.per_day_cost || 'N/A'}</p>
                    <a href="#" class="btn btn-primary w-100">Book Now</a>
                </div>
            </div>
        `;
        container.append(cardHtml); // Append the card to the container
    });
},
