將Plone 2.5x遷移到Plone 3.x後，如何糾正kss_generic_macros問題？

Question

我在以下幾個視圖中看到以下錯誤。這似乎與此處所述other kss_generic_macros後的內容相同。提供了一個答案，即「這是由於2.5-> 3.0遷移過程無法將Plone_kss圖層添加到我們的一些自定義外觀引起的。當我進入並將plone_kss手動添加到這些外觀時，它修復了這個問題「

這是唯一有用的。一個代碼示例或一個真正的指針，指向你添加plone_kss的地方，這將更容易解決。

Answer 1

登錄到ZMI，然後轉到portal_skins工具。現在點擊「屬性」標籤。該「Plone默認」的皮膚應該是這個樣子：

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 

如果你缺少其中任何你需要添加它們在這應該解決的問題。

Answer 2

你缺少plone_kss層在你的皮膚。轉到ZMI（通過網站設置或通過添加/管理您的Plone主頁），找到portal_skins工具，並在屬性選項卡中檢查您的皮膚圖層。確保plone_kss圖層在自定義圖層之前列出，並且應該設置爲去。

未來，您可以使用像find這樣的命令行工具來定位缺少的皮膚方法;我發現這是一個擴建使用以下命令：

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

你可以用下面的Python腳本自動完成：

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)) 

這個腳本遍歷在外觀工具的所有皮膚，並會將plone_kss插入缺失的任何一個;要麼在custom層之後，要麼在最後如果沒有custom層存在。

您希望您的custom圖層處於第一位的原因是，此圖層按照自定義（無雙關語）持有皮膚資產的自定義版本。如果要通過ZMI從portal_kss圖層中自定義資產，則自定義版本將被放入custom圖層中。由於外觀查找規則將從頂層到底層查看層堆棧，因此您需要確保在底層的原始文件之前找到custom圖層中的自定義版本。
