Plone 4中的自定义编辑视图

Question

我创建了一个自定义内容类型(简历),我希望提供一个自定义的"编辑"视图.我的用例非常简单,我只想在编辑表单之前显示一个HTML"免责声明"框.

首先我复制了:

Products/ATContentTypes/skins/ATContentTypes/atct_edit.cpt
Products/ATContentTypes/skins/ATContentTypes/atct_edit.cpt.metadata

进入我的/ product/browser / as

my/product/browser/resumeedit.cpt
my/product/browser/resumeedit.cpt.metadata

然后我定义了一个新的浏览器:my/product/browser/configure.zcml中的页面节:

  <browser:page
   for="..interfaces.IResume"
   name="resume_edit"
   class=".resumeview.ResumeEdit"
   template="resumeedit.cpt"
   permission="cmf.ModifyPortalContent"
   />

我的/ product/browser/resumeview.py中的resume类只是:

class ResumeEdit(BrowserView):
""" A customization of the Resume Edit form
"""
    __call__  = ViewPageTemplateFile('resumeedit.cpt')

最后,我在/ product/profiles/default/types/Resume.xml中更改了'edit'的默认别名:

  <alias from="edit" to="resume_edit" />

安装后,添加或编辑Resume内容类型会引发此异常:

Unauthorized: The container has no security assertions.  Access to 'id' of (Products.Five.browser.pagetemplatefile.ViewPageTemplateFile object at 0x1e8b7a50) denied.

通过提供修补版本的edit_macros.pt可以减轻这种情况:

85c85
<             tal:attributes="action python:context.absolute_url()+'/'+template.id;
---
>             tal:attributes="action python:context.absolute_url()+'/'+path('template/getId|nothing');
203c203
<                    tal:attributes="value python:(last_referer and '%s/%s' % (context.absolute_url(), template.id) not in last_referer) and last_referer or (context.getParentNode() and context.getParentNode().absolute_url())"
---
>                    tal:attributes="value python:(last_referer and '%s/%s' % (context.absolute_url(), path('template/getId|nothing')) not in last_referer) and last_referer or (context.getParentNode() and context.getParentNode().absolute_url())"

仍然,这引发了以下异常('id-64121786'是我的简历项的id):

  Module zope.tales.tales, line 696, in evaluate
   - URL: file:/home/zope/env26/plone-devel/eggs/Products.Archetypes-1.6.5-py2.6.egg/Products/Archetypes/skins/archetypes/widgets/field.pt

       'default': <object object at 0x8e094c0>,

       'views': <Products.Five.browser.pagetemplatefile.ViewMapper object at 0x126d8fd0>}
  Module Products.PageTemplates.ZRPythonExpr, line 49, in __call__
   - __traceback_info__: errors.get(fieldName)
  Module PythonExpr, line 1, in <expression>
  Module AccessControl.ImplPython, line 688, in guarded_getattr
AttributeError: 'NoneType' object has no attribute 'get'

如何解决此问题并为我的内容类型的编辑视图提供我自己的自定义模板？

Answer 1

我建议不要复制atct_edit.cpt.您真正需要做的就是配置一个编辑模板(看起来你知道该怎么做),然后覆盖相应的部分.请参阅此处的文档以获取更多信

另外,我先从一个完全空白的编辑模板开始.然后在其中放入一些有效的XHTML,例如<span> Hello world!</ span>并确保您可以通过单击编辑按钮来加载编辑模板.
