Pricelist Brand

This module adds a new way to target pricelist rules: by product brand. When you edit a pricelist item (a price rule inside a pricelist), the 'Apply On' field now offers a 'Brand' choice in addition to the standard options.

• Selecting 'Brand' shows a Brand field where you pick the brand the rule should apply to. The brand is required in that case, and Odoo blocks saving the rule if you leave it empty.
• Choosing any other 'Apply On' option (global, product category, product, product variant) automatically clears the brand, and choosing 'Brand' clears the product, product template and category fields, so a rule targets one thing at a time.
• The rule name is generated automatically as 'Brand: <brand name>' so it is easy to recognise in the pricelist.
• When Odoo looks for the price rules that apply to a product, it now also checks the product's brand: rules with no brand always stay eligible, and rules with a brand only apply to products of that brand.

It works on both product templates and product variants, and it extends the existing pricelist and pricelist item screens rather than adding new menus. It depends on the product brand module.
