在plone2.5x到plone3.x迁移之后，如何纠正kss_generic_macros问题？

Question

我在下面的几个视图上得到了错误。这似乎与本宏文章中描述的内容相同。答案是：“这是由于2.5->3.0的迁移过程未能将plone_kss层添加到少数定制皮肤中造成的。当我进去并手动向这些皮肤添加plone_kss时，它修复了这个问题。”

这只会很有帮助。一个代码示例或关于在哪里添加plone_kss的真正指针将使这个问题更容易解决。

Answer 1

登录到ZMI，然后转到portal_skins工具。现在单击"properties“选项卡。"Plone默认“皮肤应该如下所示：

custom
cmfeditions_views
CMFEditions
ChangeSet
kupu_plone
kupu
kupu_tests
archetypes
archetypes_kss
mimetypes_icons
plone_kss
ATContentTypes
ATReferenceBrowserWidget
ResourceRegistries
PasswordReset
gruf
plone_ecmascript
plone_wysiwyg
plone_prefs
plone_portlets
plone_templates
plone_styles
plone_form_scripts
plone_scripts
plone_forms
plone_images
plone_content
plone_login
plone_deprecated
plone_3rdParty
cmf_legacy

如果您遗漏了其中任何一个，则需要将它们添加到其中。这应该能解决这个问题。

Answer 2

您缺少了皮肤中的plone_kss层。转到ZMI (通过站点设置或将/manage添加到您的Plone主页)，找到portal_skins工具，并检查属性选项卡中的皮肤层。确保plone_kss层列在自定义层之前，并且应该设置为go。

将来，您可以使用命令行工具(如find )来查找缺少的皮肤方法；通过使用以下命令，我在构建器中找到了这个方法：

$ find parts/plone -name kss_generic_macros.*
parts/plone/CMFPlone/skins/plone_kss/kss_generic_macros.pt

您可以使用以下Python脚本自动完成此操作：

from Products.CMFCore.utils import getToolByName
layer = 'plone_kss'
skins = getToolByName(context, 'portal_skins')
for name in skins.getSkinSelections():
    path = skins.getSkinPath(name)
    path = [i.strip() for i in path.split(',')]
    if layer not in path:
        try:
            path.insert(path.index('custom') + 1, layer)
        except ValueError:
            path.append(layer)
        skins.addSkinSelection(name, ','.join(path))

这个脚本循环遍历皮肤工具中的所有皮肤，并将plone_kss插入其中任何一个缺少的地方；或者在custom层之后，或者在没有custom层的情况下。

您希望您的custom层成为第一层的原因是，此层按自定义(没有双关意)保存自定义版本的皮肤资产。如果要通过ZMI从portal_kss层自定义资产，那么定制的版本将放在custom层中。因为皮肤查找规则将从上到下查看层堆栈，所以您希望确保在custom层中的自定义版本在底层原始文件之前找到。
