z3版本和five版本的ViewPageTemplateFile差异

admin

导入时不同：
Five版

1. from Products.Five.browser.pagetemplatefile import ViewPageTemplateFile
   

复制代码

z3版

1. from zope.app.pagetemplate import ViewPageTemplateFile

复制代码

另外Five版支持：
• Acquisition.
• The provider: TAL expression.
• Other Plone-specific TAL expression functions like test().
• Usually, Plone code needs the Five version of ViewPageTemplateFile.
但是z3版：
• Some subsystems, notably the z3c.form package, expect the Zope 3 version of ViewPageTemplateFile
instances.
