[Zope3-checkins] CVS: Zope3/lib/python/Schema - _Field.py:1.11 _Schema.py:1.9 __init__.py:1.4

[Martijn Faassen]

Update of /cvs-repository/Zope3/lib/python/Schema
In directory cvs.zope.org:/tmp/cvs-serv31848/python/Schema

Modified Files:
	_Field.py _Schema.py __init__.py 
Log Message:
Refactored Forms (and Schema).

  * A FormView now specifies a single schema explicitly as the 'schema'
    (class) attribute. A schema is simply an interface with Field attributes
    on it.

  * The FormView code now uses the Schema package more for its own
    implementation, instead of trying to reimplement things itself.

  * got rid of the 'id' attribute for fields. Fields now already know what
    name they have, because of the Interface package setting __name__.
    Use getName() to get the field name.
