Get ready, Odoo developers! Odoo 19 will be officially announced next year, yet journey to Odoo 19 has begun, and it brings a significant step towards a more Pythonic approach for defining ORM models. This means saying goodbye to underscores in model names and embracing the CamelCase convention for your classes.
Why the Change?
This shift aims to achieve two key goals:
Improved Consistency: CamelCase class names will ensure a more consistent naming scheme across models.
Enhanced Pythonic Feel: Removing the _name attribute streamlines code and aligns it better with general Python practices.
How Does it Work?
As per the PR https://github.com/odoo/odoo/pull/178200
The script updates every class name to match the new convention. The name of a model (dotcase) is determined by the name of its class (camelcase) as follows. Each capital letter is lowercased and is preceded by a period, unless it is the first one or is itself preceded by an underscore. The use of underscores in model names is now discouraged.
res.users <=> ResUsers
ir.ui.view <=> IrUiView
ir.config_parameter <=> IrConfig_parameter
The _name attribute on model classes are removed, except in the case where the model name cannot be derived from the class name. The _inherit attribute is no longer used as a fallback for the model name, and only the list variant is now accepted.
For instance,
Example Transformation
Let's see how the new approach transforms some existing code snippets:
class FieldConverter(models.AbstractModel):
_name = 'ir.qweb.field'
class IntegerConverter(models.AbstractModel):
_name = 'ir.qweb.field.integer'
_inherit = 'ir.qweb.field'
class Integer (models.AbstractModel):
_name = 'ir.qweb.field.integer'
_inherit = 'ir.qweb.field.integer'
/—————-/——————/
Becomes:
/———-—-/—————-/
class IrQwebField(models.AbstractModel):
class IrQwebFieldInteger(models.AbstractModel):
_inherit = ['ir.qweb.field']
class IrQwebFieldInteger(models.AbstractModel):
_inherit = ['ir.qweb.field.integer']
