I am looking at a couple way of producing a qotd solution.
one way is to put quotes in a folder. Then use objectvalues on the folder and randomly select one of the items. I get get the objectid. but I don't know what I use to get the 'content' of the object.. what is the method to get the 'rendered' and unrendered content of an object.
In this case I'm using objects of type file (setting content type to text/plain) (ofcourse the content is plain text)
I may find the using a zpt, html, or stx object will work better. I'm hoping there is a method to get either a rendered view of the file, (if zope knows how to render it) or unrendered, and I'll worry about rendering it elsewhere.
The contents of a File object can be gotten at simply by calling it. You
sorry to be dense here. Its been a long time since I read the zope book. I have the following code: ============= from Products.PythonScripts.standard import html_quote import random request = container.REQUEST RESPONSE = request.RESPONSE # Return a string identifying this script. q = container.quotes.objectIds() print random.choice(q)() return printed =============
But this returns an TypeError, str is not callable. How do I get this code to return a random object from the quotes container?
Of course it does. What does 'objectIds' return? Answer: a list of ids (strings) and not objects. If you want objects, you must ask a different way, as another message provides. Also, there's not particular reason to use the 'print' facility. You may simply say:: return random.choice(q)() and get the same effect. --jcc
can also get at the underlying data with the 'data' attribute, which is useful if the contents are large (since it provides a 'Pdata' object rather than a string.) This is just as it says in http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixB.stx
Other object types, like those that have to do rendering, you can just call for the rendered content. Methods 'document_src' or 'read' will usually work for the source.
