问题 How to use the tal condition to check the file type and render the template in Plone 4.1 My file preview template rendering depends upon the file extension. If file extension is 'pdf', I wish to use something like this:(just started working with TAL, TALES, METAL) <tal:define="file_nm global string:${here/absolute_url}" <tal:condition="file_nm.slice[-3:] = 'pdf'"> <embed width="100%" height="100%" name="plug-in" tal:attributes="src string:${here/absolute_url}#" draggable="false" onselectstart

问题 I have a dexterity content type which is folderish and I would like to have it show up in search results based on it's child's content (pdfs etc). Is this possible, where and how would this be achieved? 回答1: One possible solution is to reindex the searchableText of the children on the parent and not on the item itself (concatenate the searchableText of all children). Your new searchableText Index could look like this: @indexer(IYourContainerType) def SearchableText(obj): searchable_text = obj

问题 i'm trying to cache the return value of a function only in case it's not None. in the following example, it makes sense to cache the result of someFunction in case it managed to obtain data from some-url for an hour. if the data could not be obtained, it does not make sense to cache the result for an hour (or more), but probably for 5 minutes (so the server for some-domain.com has some time to recover) def _cachekey(method, self, lang): return (lang, time.time() // (60 * 60)) @ram.cache(

问题 My goal is to inject some HTML-Code in front of every Plone article (between the page's header and the first paragraph)? I'm running Plone 4. Does anyone have a hint on how to realize that? The other question is: is it possible to place some HTML code randomly in every Plone article? 回答1: Use viewlets for both usecases. A viewlet can be inserted in different parts of the rendered page, depending on both the viewlet manager you register it to and and what interfaces the viewlet applies to. The

问题 I'm trying to add add-ons to Plone through buildout but it can't find the packages. I've tried it in a virtualenv andd the system wide python I followed the set up on the Plone site Setup instructions Every add-on I try brings up the following error Installing instance. /home/a/Plone/zinstance/local/lib/python2.7/site-packages/pkg_resources/__init__.py:192: RuntimeWarning: You have iterated over the result of pkg_resources.parse_version.

问题 I have a little Plone extension which contains a simple Archetypes-based content type (the same which I had not been able to add TTW, see my previous question); the project setup is on GitHub. After adding an object, I get a KeyError: 'view' during execution of the plone.abovecontenttitle content provider: {'container': <MyType at /plone/test-for-new-types/a-mytype-object>, 'context': <MyType at /plone/test-for-new-types/a-mytype-object>, 'default': <object object at 0x7fc4f8ebe520>, 'here':

问题 As far as I understand it, a transformation chain is filled with transforms after calculating the shortest path between original and target mimetypes (see convertTo() and _findPath() in Products.PortalTransforms.TransformEngine ). How can I hook a transformation in the transformation chain. Are there maybe other means to hook a transformation? If yes are there some example or documentation? 来源： https://stackoverflow.com/questions/24222774/how-can-i-hook-a-transformation-in-the-transformation

问题 On the sharing tab of any Folder or File, I can untick "Inherit permissions from higher levels", but when I click save, it does not stick. I do not want my SalesGroup to have access to or even see the name of my ManagementFolder. Plone 4.3.1 running on Windows. I have tried logging into Plone as admin & a folder owner. I have also tried from multiple browsers. 来源： https://stackoverflow.com/questions/18604039/plone-cannot-untick-inherit-permissions-from-higher-levels
