Zope supports Python builin functions?
by picasso＠videotron.ca 14 Sep '99

14 Sep '99

Hi, Does Zope support Python builtin functions outside External Methods? I made a DTML Methode with juste one line: <dtml-var "4==5"> after clicking on the view tab I got: 0 Perfect. Then I change the line to: <dtml-var "type([])==type({})"> Viewing it displays: ************ Zope Error Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: type etc....... ************ I know the test is stupid, i just wanted to know if it was possible to use Python builin function inside a simple DTML Method. I understand it's not. Is it right?

This is the same message, but I think the python code is now correctly formatted: ------- On Mon, 13 Sep 1999 17:34:23, Katrin <katrin(a)beehive.de> wrote: > hi everybody! > > i have a little problem with permission settings. > > i'm writing a product in python. the product installs dtml methods when > installed in a folder. now i want zope to ask for the user name and the > password when a certain page is rendered as an URL (zope doesn't have a user name yet). > >i found out that in order to get the zope login window, i have to uncheck the view permission of the page (i mean the checkbox for > acquire permission settings). how can i uncheck the box > using python in my product? or how can i delete the view permission > for this page in my product? If I understand your problem correctly, you want to install the DTML method to have the acquired permissions for View permission unchecked, and then (I guess,) enabled view permission for some role which you have defined a set of users for? I did something like this with some Python code in a homegrown user authentication class I've been playing around with: # remove view and access permissions from acquired permissions and anonymous role acq_permissions = your_method.permission_settings() new_permissions = [] for d in acq_permissions: if d['name'] != 'View': new_permissions.append(d['name']) your_method.manage_acquiredPermissions(new_permissions) your_method.manage_role(role_to_manage='Anonymous',permissions=new_permissions) Basically, what it is doing is: 1. get the current list of acquired permissions from your dtml_method (<object>.permission_settings()) 2. create a new list of permissions without the View permission (that's the what the loop is doing) -- you could also just create a hardcoded list and not have to loop (then you don't have to do the first step too) 3. set your object's acquired permissions using (<object>.manage_acquiredPermissions(new_permissions) 4. set the anonymous role's permissions to the the new permissions (w/o the View permission) (<object>.manage_role(role_to_manage='Anonymous',permissions=new_permissions)) 5. You also probably need add a step to add view permissions for some role (i.e. Manager) so that they have the view permission to access your method using the manage_role method (<object>.manage_role(role_to_manage='Manager',permissions=['View','View Management',...]) If you are writing your constructor method in DTML, you probably could use the same methods that I used. The only complication I see in writing it with DTML is implementing the loop (which could be circumvented if you use a hardcoded list)... Hope this helps.

I think Kevin is right, I cleared the cache in IE and the right icons came back. It remains it's an issue if the changes made in your Website are not reflected in the end user brower. Has anyone experienced the same kind of problems, with for example PHP + Apache, or other Web Servers? >>The Zclass icons are buggy. >>I've often set one icon to a zclass then changed it to >>a second icon, but not seen the change until days later. > >I've noticed this too, but I've been wondering if it was a browser caching >.... >Kevin >

I've noticed this too, but I've been wondering if it was a browser caching issue. The reason I wondered this is because I exported a product from my local machine (which was display the wrong icon) and then imported it on a different server and it then displayed the correct icon. I've noticed that IE seems to cache some things rather "vigorously". (I haven't been able to figure out how to get it to stop caching Flash movies). >Is there a proper route for submitting bugs or is it cool >enough to post to list (and hence warn others too) ? >I presume DC harvest bugs from the list. Bugs should be submitted to the Collector on the Zope site... It is generally not safe to assume that DC will notice a bug that flies by on the mailing list. Kevin

Job--Web/Zope developer at the Univ. of Pittsburgh
by Jim Harrison 14 Sep '99

14 Sep '99

We're recruiting for a talented web developer to reorganize our departmental Web sites and manage them as a distributed electronic publishing environment. The Department of Pathology at the University of Pittsburgh has one of the largest Medical Pathology sites, with about 700,000 hits (about 60,000 user sessions) per month. The site includes Internet/intranet information serving 17 hospitals in southwest Pennsylvania, over 200 clinical case studies (with more added regularly) used nationally for educational purposes including Internet-based continuing medical education for physicians, and support for a national conference in Pathology Informatics that includes real-time RealAudio streaming servers. The manual maintenance of this diverse information by a small central core of Web managers has become unwieldy and we recognize the need to decentralize authorship for much of our content. We also recognize the need to move beyond static pages to create Web applications that augment our work in teaching, research and clinical practice. Thus our interest in Zope and Zope developers. Our goal is to make the University of Pittsburgh Pathology site the premier Medical Pathology site in the nation and to create a model for a distributed authorship system that can be applied to the University of Pittsburgh Medical Center in general. The immediate task for the new developer will be to consolidate management of the servers, unify the information presentation, decentralize content creation, and work with the the site's new Medical Director (me) to create and manage a plan for site development. Salary is in the range of $45 - 55K, depending on qualifications and experience. This is a chance to work with good people on a project that has national attention (at least in the field of Pathology) and also has local impact and meaning. Plus, IMHO, Pittsburgh is a nice place with a reasonable cost-of-living. Reference URLs: http://path.upmc.edu/ http://aplis.upmc.edu/ http://tpis.upmc.edu/ http://telepathology.upmc.edu/ http://apiii.upmc.edu/ Please email me directly or give me a call (see below) if you'd like further details.

Problems with icons in ZClass instance (Q1959)
by picasso＠videotron.ca 14 Sep '99

14 Sep '99

Hi, I tried to create CD instances as described in the ZClasses tutorial. In the Basic view of '/Control_Panel/Products/CDProduct/CDClass' I selected an image file from my computer by clicking the Browse button. The icon looks perfect. However when i try to create an instance of my ZClass in the root folder, all it's ok except it diplays a completly different logo. What's wrong?
