Dynamic snippets are an integral part of Odoo's website builder. They enable users to create dynamic content blocks that can adapt to different situations and user interactions. These dynamic snippets can be used to display products, services, events, or any other content that may change over time. However, to make these snippets truly effective, it's essential to provide users with the ability to filter and sort the displayed content according to their preferences.
Customization of Dynamic Snippet Filters
Customizing dynamic snippet filters in Odoo 16 empowers businesses to tailor their website content more effectively. Let's delve into the steps required to achieve this customization.
First, we have to create a server action that calls the function which fetches the data for the filter. Then we have to create a filter in the backend as a record of the ‘website.snippet.filter’ model and add the server action in the field ‘action_server_id’.
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<data>
<record id="dynamic_snippet_customize_filter_action" model="ir.actions.server">
<field name="name">Customize Filter</field>
<field name="model_id" ref="product.model_product_product"/>
<field name="state">code</field>
<field name="code">
DynamicFilter = model.env['website.snippet.filter']
response = DynamicFilter._get_products('customize_filter', model.env.context)
</field>
</record>
<record id="dynamic_filter_customize_filter" model="website.snippet.filter">
<field name="action_server_id" ref="your_module.dynamic_snippet_customize_filter_action"/>
<field name="field_names">
display_name,description_sale,image_512,price:monetary</field>
<field name="limit" eval="16"/>
<field name="name">Customize Filter Products</field>
</record>
</data>
</odoo>
Please remember to add the xml file to manifest under data files. The server action calls the method ‘_get_products()’ defined inside the model ‘website.snippet.filter’.
@api.model
def _get_products(self, mode, context):
dynamic_filter = context.get('dynamic_filter')
handler = getattr(self, '_get_products_%s' % mode, self._get_products_latest_sold)
website = self.env['website'].get_current_website()
search_domain = context.get('search_domain')
limit = context.get('limit')
domain = expression.AND([
[('website_published', '=', True)],
website.website_domain(),
[('company_id', 'in', [False, website.company_id.id])],
search_domain or [],
])
products = handler(website, limit, domain, context)
return dynamic_filter._filter_records_to_values(products, False)
This method is defined inside the ‘website.snippet.filter’ model. Here the value of parameter ‘mode’ is ‘customize_filter’. In the statement handler = getattr(self,
'_get_products_%s' % mode, self._get_products_latest_sold)
We call the function ‘_get_products_customize_filter()’ which we will define in our custom module inside the ‘website.snippet.filter’ model.
def _get_products_customize_filter(self, website, limit, domain, context):
products = []
visitor = self.env['website.visitor']._get_visitor_from_request()
if visitor:
excluded_products = website.sale_get_order().order_line.product_id.ids
tracked_products = self.env['website.track'].sudo().read_group(
[('visitor_id', '=', visitor.id), ('product_id', '!=', False), ('product_id.website_published', '=', True), ('product_id', 'not in', excluded_products)],
['product_id', 'visit_datetime:max'], ['product_id'], limit=limit, orderby='visit_datetime DESC')
products_ids = [product['product_id'][0] for product in tracked_products]
if products_ids:
domain = expression.AND([
domain,
[('id', 'in', products_ids)],
])
products = self.env['product.product'].with_context(display_default_code=False, add2cart_rerender=True).search(domain, limit=limit)
return products
In this function, we can define which products should be shown in the dynamic snippet. Here the function filters out the recently viewed products.
After this let's open a dynamic snippet and see if our filter is visible inside the options.
Here we can see the products in the dynamic snippet which are shown according to the default filter ‘Newest Products’. 
And when we open the snippet option there under filters we can see our custom filter.
Now let's select the custom filter and see what happens.
And when the filter is applied the snippet shows the recently viewed products as we can see.
