ERP5 Naming Conventions
This document defines ERP5 naming conventions.
Coding Conventions
"Python coding conventions":http://www.python.org/doc/essays/styleguide.html
is a good start for python coders. It defines precisely the multipole
naming conventions from which we have to choose. A must read.
Zope extends the python object model by adding
- Zope Objects: objects which can be published
and accessed through the OFS implement acquisition of attributes
and, in certain cases, skinning
- Zope Methods: it is possible to extend the behaviour of
a Zope Object as defined in its class by calling special
kinds of methods (DTML, Page Template, Python Script) stored
in the OFS as Zope Objects
Pseudo Constant
A pseudo-constant is a global reusable value stored as
an attribute (of a Class, of a module) which is
considered as a constant.
Example::
CONSTANT_NAME
Attributes, Properties and IDs
Attributes can be assigned to an object, to a class.
Properties can be assigned to Zope object.
Example::
base_price
attribute_name
Variables
Variables can be defined within a python method or function,
within a python script Zope object, within a page template Zope
Object or within a DTML Method Zope Object.
Example::
base_price
attribute_name
Class
Classes are defined in python within products.
Example::
Document
MetaResource
Resource
ClassName
Interface
mixedCase that, is CapitalizedWords with initial lowercase
Example::
content
dublinCore
rdf
interfaceName
Method
Methods are defined for each class in python.
Example::
Title
BasePrice
edit
setPrice
Exceptions for mixed start::
set
get
view
edit
delete
print
list
add
Exception if ZMI::
manage_MethodName
Page Template
Pages templates are stored as IDs in the OFS
(therefore small caps) but act as methods of objects (therefore
CapitalizedWords)
Example::
content_AddToCart
content_edit
interfaceName_MethodName
