This field describes a python identifier, i.e. a variable name.
Let's look at an example:
>>> class FauxContext(object): ... pass >>> context = FauxContext() >>> field = PythonIdentifier().bind(context)
Let's test the fromUnicode method:
>>> field.fromUnicode(u'foo') u'foo' >>> field.fromUnicode(u'foo3') u'foo3' >>> field.fromUnicode(u'_foo3') u'_foo3'
Now let's see whether validation works alright
>>> for value in (u'foo', u'foo3', u'foo_', u'_foo3', u'foo_3', u'foo3_'): ... field._validate(value) >>> >>> from zope import schema >>> >>> for value in (u'3foo', u'foo:', u'\\', u''): ... try: ... field._validate(value) ... except schema.ValidationError: ... print 'Validation Error' Validation Error Validation Error Validation Error Validation Error
