When the variant has no code, the template code is the only part of the unique constraint. In such case copying the template fails because the new variant will have the same code. issue9462 review306081002
Product Module
##############
The Product module defines the following models: Category of Unit of
Measure, Unit of Measure, Product Template, Product and Product
Category.
Category of Unit of Measure
***************************
A Category of Unit of Measure is simply defined by a name.
Unit of Measure
***************
A Unit of Measure is defined by:
- Name.
- Symbol.
- UOM category.
- Rate and a Factor (the later is the inverse of the former).
- Rounding Precision and Display Digits, used to round and display
quantities expressed in the given UOM.
- Active, allow to disable a UOM.
Product category
****************
The Product Category Model is just composed of a name. Product
Categories are organised in a tree structure.
Product Template and Product
****************************
The product concept in Tryton is composed of two models: Product
Template and Product.
The Product Template model contains the following fields:
- Name.
- Code, a common prefix for all products.
- Type, whose value can be *Goods*, *Assets*, *Service*.
- Category.
- List Price, the default sale price expressed in the List Price UOM.
product.
- List Price UOM.
- Cost Price, the cost for one unit of this product expressed in the
Cost Price UOM.
- Cost Price UOM.
- Cost Price Method, which can be *Fixed* or *Average*. Defines how
the cost price should be updated. *Fixed* means that the cost price
stay unchanged. *Average* means that the cost price is the average
cost of all the items that are in stock. It's default value can be defined
on product configuration.
- Default UOM. The default UOM for this product. Used for example to
express stock levels.
- Active, allow to disable a product.
The Product model extends the Product Template with two fields: Code (aka SKU_)
and Description. If a sequence is set on product configuration the code will be
read-only and will be filled in using the sequence. It's also possible to
define a list of identifiers on product. An identifier is composed by a type
and a code. The following types are available:
* International Article Number (EAN)
* International Standard Audiovisual Number (ISAN)
* International Standard Book Number (ISBN)
* International Standard Identifier for Libraries (ISIL)
* International Securities Identification Number (ISIN)
* International Standard Music Number (ISMN)

- `price_decimal`: defines the number of decimal digits with which the unit
prices are stored. The default value is `4`.
- `uom_conversion_decimal`: defines the number of decimal digits with which the
conversion rates and factors of UoM are stored. The default value is `12`.
