Creating a learning environment with CMF
by Hamish Lawson 20 May '01

20 May '01

I'm looking at creating a learning environment system for use within our institution using the Content Management Framework. The tutor for a given course unit would have a space in which they could provide notes and other resources - discussion forums, quizzes, etc. The tutor should also be to decide who gets to use the resources for their particular unit (although they won't be responsible for creating users in the first place, such details likely coming from an LDAP directory). I will probably want to be able to make custom CMF-aware tools available to all builders of course units. My question is whether each course unit should be a separate CMF Portal instance, or whether there should be one Portal instance and some folderish product being used for the course units?

Finding virtual objects in dtml namespace
by kosh＠aesaeion.com 20 May '01

20 May '01

Inside my python I give people the ability to use dtml to change the output layout of the object however I want to give them the ability to do that with the management pages also. lets say I have an object foo and all objects have a manage_inline_edit_form method. I want to be able to do preferably <dtml-var foo> and be able to change the namespace such that it calls foos manage_inline_edit_form. Another acceptable way would be for something like <dtml-var editfoo> to call the manage_inline_edit_form of the object foo. The main caveat for something like this is I need these items to still draw correctly when put in the layout so I think it needs to be a namespace change rather then changing the rendering of the object itself by default. What are possible ways to do this? Thanks Designing the webpages of tomorrow http://webme-eng.com Designing the MMORPGS of tomorrow http://worldforge.org

image caching
by kosh＠aesaeion.com 20 May '01

20 May '01

I have a class that wraps images and I want to be able to set the HTTP headers for the object when it is requested. Which method do you need to override in my python product to catch all requests to that object? Currently the structure is set up such that I have a Picture object and in its dict I store a regular zope Image object. It also stores a thumbnail and a good bit of other information. I want to override however that image gets handed off to the browser or to the rest of zope.

ZClasses (Folders or just ObjectManager?)
by Tim Cook 20 May '01

20 May '01

I'm trying to determine if I am carrying around extra baggage by subclassing Folder in my ZClasses instead of just ObjectManager. It seems that ObjectManager would do just fine since I create my own propertysheets anyway. Is there an advantage to NOT using Folder? Speed? Memory consumption?

Setting a Cookie
by Tommy Johnson 19 May '01

19 May '01

Hey all, I'm trying to set a cookie. Simple right? hehe - if so, then I wouldn't be here. ;-) Ok, I have the syntax in front of me. I have this bit of code to set the cookie: <dtml-call "RESPONSE.setCookie('CookieMonster', '458468')"> All is well when I save the dtml document and when I run the page. The problem - the cookie isn't set! Now I remember this problem when I worked with ASP. It turns out that you had to set an expire date also (although they said that if you didn't, the cookie expires when you close the browser and nothing gets written to the client machine.) That would be good - IF ONLY I COULD ACCESS THE INFORMATION I SET. Sorry 'bout that. But it's fustrating to see this problem come up again with another language. So I set an expire date. But, get this, now it fails when the page is loaded. The error message says that the method expected three parameters, but received four. Do you see four parameters here? <dtml-call "RESPONSE.setCookie('CookieMonster', '458468', 'Sunday 20-05- 2001 12:00:00 GMT')"> I initially had a comma between Wdy, Date - because that is the DOCUMENTED syntax, but this seems incorrect also. Here's the error message: Error Type: TypeError Error Value: too many arguments; expected 3, got 4 Any suggestions? Proven code would be appreciated. Thanks in advance, Tommy

return object from script
by Ulrich Wisser 19 May '01

19 May '01

Hi, my python script returns an array of dictionaries, like: [{'num':1, 'letter':'a'},{'num':2, 'letter':'b'}] in a dtml-document I try to print these values: <dtml-in "script(param=param)"> <dtml-var num><br><dtml-var letter> </dtml-in> This results in a key error. How do I have to return the values to make the dtml-code work? I know <dtml-var "_['sequence-item']['num']"> works, but I want<dtml-var num> to work.
