Hi!

product.product vs product.template

I have already search quite a lot about this subject and studied the source code, but still cant wrap my head around it.

class ProductTemplate(models.Model):
    _inherit = 'product.template'

    available_in_pos = fields.Boolean(string='Available in Point of Sale', help='Check if you want this product to appear in the Point of Sale', default=True)
    to_weight = fields.Boolean(string='To Weigh With Scale', help="Check if the product should be weighted using the hardware scale integration")
    pos_categ_id = fields.Many2one(
        'pos.category', string='Point of Sale Category',
        help="Those categories are used to group similar products for point of sale.")

Ok, so POS inherits from product.template, but still in the data files (point_of_sale_demo.xml) it uses product.product like so:

<record id="boni_orange" model="product.product">
    <field name="available_in_pos">True</field>
    <field name="list_price">1.98</field>
    <field name="name">Boni Oranges</field>
    <field name="to_weight">True</field>
    <field name="barcode">2100002000003</field>
    <field name="taxes_id">False</field>
    <field name="pos_categ_id" ref="fruits_vegetables"/>
    <field name="uom_id" ref="product.product_uom_kgm" />
    <field name="uom_po_id" ref="product.product_uom_kgm" />
    <field name="image" type="base64" file="point_of_sale/static/img/boni_orange-image.jpg"/>
</record>

What is the difference?

Whats really going on here?

Which of the models should I use?

This is very confusing and I can't find a good explanation anywhere, someone care to try?

Thanks! :)

PS. I know there are answers out there trying to expain this, but I still don't get it. Example:
