How to Create a Dynamic Snippet in Odoo 17

Technical Odoo 17

Dynamic snippets in Odoo 17 are modular components that allow for the dynamic display of content on web pages. These snippets can be tailored to showcase various types of information, such as product listings, testimonials, or promotional banners. What sets dynamic snippets apart is their ability to adapt and update based on predefined rules or conditions, offering a personalized and engaging browsing experience for users.

To craft a dynamic snippet, several components need to be developed: an XML file to define the snippet's view, a Python controller to retrieve data from the backend, and a JavaScript file to display backend data on the website.

Initially, the controller is defined to retrieve data from the backend. In the provided example, we extract the total number of products sold.

import time
from odoo import http
from odoo.http import request
class DynamicSnippets(http.Controller):
   """This class is for the getting values for dynamic product snippets
      """
   @http.route('/top_selling_products', type='json', auth='public')
   def top_selling(self):
       """Function for getting the current website,top sold products and
          its categories.
           Return
                 products-most sold products
                 unique_categories-categories of all products
                 current_website-the current website for checking products or
           """
       current_website = request.env['website'].sudo().get_current_website().id
       public_categ_id = request.env[
           'product.public.category'].sudo().search_read([], ['name',
                                                             'website_id'])
       products = []
       public_categories = []
       for category in public_categ_id:
           products_search_read = request.env['product.template'].with_user(
               1).search_read(
               [('is_published', '=', True),
                ('public_categ_ids.id', '=', category['id'])],
               ['name', 'image_1920', 'public_categ_ids', 'website_id',
                'sales_count', 'list_price'], order='sales_count')
           for product in products_search_read:
               if product['sales_count'] != 0:
                   products.append(product)
                   public_categories.append(category)
       unique_categories = [dict(categories) for categories in
                            {tuple(sorted(record.items())) for record in
                             public_categories}]
       products = sorted(products, key=lambda i: i['sales_count'],
                         reverse=True)
       unique_id = "pc-%d" % int(time.time() * 1000)
       return products, unique_categories, current_website, unique_id

Next, we must generate an XML file in static/src/xml. Give an outline content of the snippet.

<template id="products_category_wise_template" name="Best Seller">
        <!--        Template Best seller product dynamic snippet-->
        <section class="best_seller_product_snippet">
           <div class="ref-arrival-content">
                <p class="ref-section_head ref-centerhead__underline ref-head--primary"
                   style="color: #0d5272;">Best Seller
                </p>
            </div>
            <div id="top_products_carousel"/>
        </section>
    </template>

In this step, we've introduced a "total_sold" span element to display the total number of sold products. The value for this span will be retrieved through JavaScript and rendered accordingly.

Once the snippet's view is defined, it's essential to integrate the snippet into the website builder's snippet blocks. To achieve this, we inherit the "website.snippets" template and incorporate our newly created snippet into it.

<?xml version="1.0" encoding="UTF-8" ?>
<odoo>
<template id="basic_snippet" inherit_id="website.snippets" name="Best seller Snippet">
<xpath expr="//div[@id='snippet_effect']//t[@t-snippet][last()]"
               position="after">
            <t t-snippet="module_name.products_category_wise_template"/>
</xpath>
</template>
</odoo>

Now, our snippet is part of the Dynamic snippet section. Next, to show the data on the website, we'll use JavaScript.

/** @odoo-module */
import PublicWidget from "@web/legacy/js/public/public_widget";
import { jsonrpc } from "@web/core/network/rpc_service";
import { renderToElement } from "@web/core/utils/render";
export function _chunk(array, size) {
    const result = [];
    for (let i = 0; i < array.length; i += size) {
        result.push(array.slice(i, i + size));
    }
    return result;
}
var TopSellingProducts = PublicWidget.Widget.extend({
        selector: '.best_seller_product_snippet',
        willStart: async function () {
            const data = await jsonrpc('/top_selling_products', {})
            const [products, categories, website_id, unique_id] = data
            Object.assign(this, {
                products, categories, website_id, unique_id
            })
        },
        start: function () {
            const refEl = this.$el.find("#top_products_carousel")
            const { products, categories, current_website_id, products_list} = this
            const chunkData = chunk(products, 4)
            refEl.html(renderToElement(module_name.products_category_wise', {
                products,
                categories,
                current_website_id,
                products_list,
                chunkData
            }))
        }
    });
PublicWidget.registry.products_category_wise_snippet = TopSellingProducts;
return TopSellingProducts;

In this step, we select sections using a class and retrieve data from the controller through jsonrpc call. Following this, we include an XML file in the data section and a JavaScript file in the asset action of the "__manifest__.py" file.

'data': [
        'views/snippet.xml'
    ],
    'assets': {
       'web.assets_frontend': [
           'module_name/static/src/js/best_seller_snippet.js',
             'module_name/static/src/xml/best_seller_snippet_templates.xml',
       ],
    },

After installing or upgrading the module, navigate to the website and click on "Edit." You'll notice our snippet listed under "Dynamic Content," allowing you to easily drag and drop it onto the desired section of your webpage.
