Question

目前我正在尝试设置一个表格来创建一个新闻项目。到目前为止，脚本工作正常。文件字段出现问题：当我尝试通过request.form ['pub-core-cover']访问该文件时，我得到了一个“模块AccessControl.ZopeGuards，第67行，在guarded_getitem中”。

我被建议使用HelperView来绕过RestrictedPython，这似乎是这里的问题。这对我来说非常困难，因为到目前为止我还没有开发过附加产品。不知何故，我想知道是否有另一种可能性使PFG中的文件字段功能在RestrictedPython中再次工作。否则，文件字段会以某种方式变为obsolet。

CustomScript-Adapter（不介意德语评论）：

form = request.form

# ID des Zielverzeichnisses ist publikationen
target = context.publikationen

# Einmalige ID für das neu zu erstellende Objekt erstellen anhand des Datums + Uhrzeit
from DateTime import DateTime
uid = str(DateTime().millis())

# Titel und ID festlegen und damit News-Objekt erzeugen (Titel + Beschreibung)
title = form['author-prename'] + " " + form['author-surname']
desc = form['pub-core-title'] + " " + form['pub-core-subtitle']

target.invokeFactory("News Item", id = uid, title = title.upper(), description = desc, image = form['pub-core-cover'])

# Objekt aufspüren und ContentType festlegen
obj = target[uid]
obj.setContentType('text/html')

# Inhalt des News-Items setzen
obj.setText("<p>"+ form['pub-core-description'] +"<br /><br />Veröffentlicht: "+ form['pub-tech-year'] +"<br />ISBN: "+ form['pub-tech-isbn'] +"<br />Preis: "+ form['pub-tech-price'] +"<br />" + form['pub-tech-pages'] + " Seiten, " + form['pub-tech-binding'] + "</p>")

# Objekt veröffentlichen ohne den Initial-State im Workflow zu verändern
obj.portal_workflow.doActionFor(obj, 'publish', comment='Dieser Inhalt wurde über den PythonScriptAdapter von PloneFormGen automatisch publiziert.')

# Content reindexieren, um das neue Objekt anzuzeigen
obj.reindexObject()

在Plone3中使用非常相似的代码我没有遇到任何困难。我会感激任何让我摆脱痛苦的帮助。

Answer 1

正如vangheem所说，它不是RestrictedPython-问题，必须要做PloneFormGen如何处理数据字段。将_file添加到变量名称非常重要。

可以从PloneFormGen脚本在RestrictedPython中访问文件上传吗？
