Problems creating auto-navigation links (LONG)
by Dave Lehman 13 Sep '01

I have a sense that I may be trying too >hard or that I've created some complexity here that I didn't need to >(or that my ISP has done so). I have just finished wrestling with exactly this problem! Coincidentally enough, also on a Zope site at Hurrah. (And I would strongly concur that David Elkins is very helpful and knowledgeable. I'm sure if you ask him, he'll shake his head and tell you all kinds of stories about me...) Here are the problems I encountered, and how I overcame them. In this example, I have a Zope CMF site inside a folder called "portal". My domain name points directly to the portal folder, so when users go to "http://www.mysite.com" they are already at the root of my CMF site, instead of having to go into the portal folder. That is: http://www.mysite.com is mapped to http://mysite.hurrah.com/cgi-bin/Zope.cgi/portal/ 1. If possible, breadcrumbs should display the friendly-reading title for each folder instead of the usually cryptic Id Most breadcrumb implementations that i had found just iterated back through the id's of all the parent folders. But instead of displaying: home/my_folder/folder125/some_story I wanted to display something like: Home / My Folder / Stories / The Quest for the Holy Grail However, it *should* use the Id if you forgot to assign a title to a certain folder. After going a couple of rounds with DTML and Python, and pleading my ignorance to the list, Tres Seaver finally did things The Right Way(tm) and supplied a Python script (see below) which returns a data structure that could be used to create the actual breadcrumbs. 2. Each breadcrumb should be hyperlinked to it's folder, except for the "leaf" breadcrumb, which is the page you're currently on. OK, now we're getting somewhere. This is minor, but took a bit of thinking on my part. I wanted each step of the breadcrumb "chain" to be a hyperlink to that actual folder (so that the user could step back to any part of the folder hierarchy) except for the leaf folder-- which is the user's current location. Once I had the right python script, this turned out to be just a TAL condition statement: tal:condition="repeat/crumb/end" 3. The hyperlinks returned by a breadcrumb should only start at the "root" of the CMF site, which isn't (necessarily) the same as the root of your Zope installation So I had it *almost* working, but the hyperlinks for each breadcrumb returned something like "http://mysite.com/portal/folder1" when what I wanted was "http://mysite.com/folder1". Initially, I wrote thought I would have to augment my python script to manually strip out the "portal" section of the URL, but that seemed unnecessarily ugly (and thank goodness it was). The key here was to create a "SiteRoot" object in my /portal folder to tell Zope that it should make this folder look like the root of the site to the website visitor. Now the "crumb/url" returned by the page template is correct. The code I used is shown below. It looks simple once you have all the pieces, but for a Zope-Newbie like myself, it took a bit of work to figure out how to get exactly what I wanted. But at least I had confidence all along that Zope *could* do what I wanted, if I just could figure out how... I'm sure all this is as clear as mud. Please let me know if you want more clarification. Regards, Dave -------------------- (This page template is pretty of ugly-- i'm obviously no ZPT guru-- so anyone should feel free to clean this up!) but does the job. It creates the breadcrumbs string, hyperlinked at each level except the leaf, and displays the Title for that folder, when possible.) "breadcrumb_zpt" (PageTemplate) * put in portal_skins/custom folder <div tal:define="crumbs here/breadcrumbs"> <span tal:repeat="crumb crumbs">/ <span tal:condition="repeat/crumb/end"> <span tal:condition="crumb/title" tal:replace="crumb/title">title</span> <span tal:condition="not:crumb/title" tal:replace="crumb/id">id</span> </span> <span tal:condition="not:repeat/crumb/end"> <a href="url" tal:attributes="href crumb/url"> <span tal:condition="crumb/title" tal:replace="crumb/title">title</span> <span tal:condition="not:crumb/title" tal:replace="crumb/id">id</span> </a> </span> </span> </div> -------------------- "Breadcrumbs" (Python script) * put in root CMF folder ## Script (Python) "breadcrumbs.py $Revision: 1.1 $" ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters=include_root=1 ##title=Return breadcrumbs ## from string import join result = [] portal_url = context.portal_url() if include_root: result.append( { 'id' : 'root' , 'title' : context.portal_properties.title() , 'url' : portal_url } ) relative = context.portal_url.getRelativeContentPath( context ) portal = context.portal_url.getPortalObject() for i in range( len( relative ) ): now = relative[ :i+1 ] obj = portal.restrictedTraverse( now ) result.append( { 'id' : now[ -1 ] , 'title' : obj.Title() , 'url' : portal_url + '/' + join( now, '/' ) } ) return result -------------------- SiteRoot object * if necessary, install the "SiteRoot" product * go to your CMF folder (or wherever you want the root to be) and create a SiteRoot object title: whatever base: http://www.mysite.com path: /

Using an external database such as MySQL, does Zope(2-3-2) (or Python-in-Zope) provide any mechanism to retrieve the names of the columns queried, rather than simply the DATA within those columns? Please allow me to obfuscate this question with an example of what I need.. :-) ==================================================UNTESTED <dtml-in "user_query(fname='Bob')"> <dtml-let record=sequence-item> <dtml-if sequence-start> <table> <tr> <dtml-in "_.range(_.len(record))"> <th> <dtml-var "record[_['sequence-index']].title"> </td>  </dtml-in> </tr> </dtml-if> <tr> <dtml-in "_.range(_.len(record))"> <td> <dtml-var "record[_['sequence-index']]"> </td> </dtml-in> </tr> <dtml-if sequence-end> </table> </dtml-if> </dtml-let> </dtml-in> ==================================================UNTESTED Thanks (again) in advance... ------------ Brian Withun Web Developer Hilgraeve, Inc.

Kind words from a neighbor
by Rich Pezzullo 13 Sep '01

13 Sep '01

Dear , I don't usually pass along stuff that's forwarded to me, but this, from a Canadian newspaper, is worth sharing. America: The Good Neighbor. Widespread but only partial news coverage was given recently to a remarkable editorial broadcast from Toronto by Gordon Sinclair, a Canadian television commentator. What follows is the full text of his trenchant remarks as printed in the Congressional Record: "This Canadian thinks it is time to speak up for the Americans as the most generous and possibly the least appreciated people on all the earth. Germany, Japan and, to a lesser extent, Britain and Italy were lifted out of the debris of war by the Americans who poured in billions of dollars and forgave other billions in debts. None of these countries is today paying even the interest on its remaining debts to the United States. When France was in danger of collapsing in 1956, it was the Americans who propped it up, and their reward was to be insulted and swindled on the streets of Paris. I was there. I saw it. When earthquakes hit distant cities, it is the United States that hurries in to help. This spring, 59 American communities were flattened by tornadoes. Nobody helped. The Marshall Plan and the Truman Policy pumped billions of dollars into discouraged countries. Now newspapers in those countries are writing about the decadent, warmongering Americans. I'd like to see just one of those countries that is gloating over the erosion of the United States dollar build its own airplane. Does any other country in the world have a plane to equal the Boeing Jumbo Jet, the Lockheed Tri-Star, or the Douglas DC10? If so, why don't they fly them? Why do all the International lines except Russia fly American Planes? Why does no other land on earth even consider putting a man or woman on the moon? You talk about Japanese technocracy, and you get radios. You talk about German technocracy, and you get automobiles. You talk about American technocracy, and you find men on the moon -! not once, but several times - and safely home again. You talk about scandals, and the Americans put theirs right in the store window for everybody to look at. Even their draft-dodgers are not pursued and hounded. They are here on our streets, and most of them, unless they are breaking Canadian laws, are getting American dollars from ma and pa at home to spend here. When the railways of France, Germany and India were breaking down through age, it was the Americans who rebuilt them. When the Pennsylvania Railroad and the New York Central went broke, nobody loaned them an old caboose. Both are still broke. I can name you 5000 times when the Americans raced to the help of other people in trouble. Can you name me even one time when someone else raced of the Americans in trouble? I don't think there was outside help even during the San Francisco earthquake. Our neighbors have faced it alone, and I'm one Canadian who is damned tired of hearing them get kicked around. They will come out of this thing with their flag high. And when they do, they are entitled to thumb their nose at the lands that are gloating over their present troubles. I hope Canada is not one of those." Stand proud, America! This is one of the best editorials that I have ever read regarding the United States. It is nice that one man realizes it. I only wish that the rest of the world would realize it. We are always blamed for everything and never even get a thank you for the things we do. I would hope that each of you would send this to as many people as you can and emphasize that they should send it to as many of their friends until this letter is sent to every person on the web. I am just a single Amerian that has read this. I SURE HOPE THAT A LOT MORE READ IT SOON.

Change Ownership
by Chris Withers 13 Sep '01

13 Sep '01

Hi, Can someone explain for a dummy like me how I'm supposed to change the owner of an object? I always assumed it'd be on the Ownership tab, but while that shows you who the owner of an object is, it doesn't let you change it. Basically, a the object is owned by a summer student who has since left, my only option now is to re-create a user object for them with a garbled password, which is majorly sucky! cheers, Chris

RE: [Zope] Creating help files for Python Products
by Schmidt, Allen J. 13 Sep '01

This got me thinking and I apologize if has been gone over before. Outside of products and special things, how can I create my own 'help' files based upon just a folder? I have 'applications' I have built that are just folders with documents and methods and ZSQL stuff. I would like to add a help file that relates to the process of what goes on in that folder. Like how data is gathered and from where. Order of events for doing things, etc. Stuff like that. Can I just create my own 'folder-help' file and have it added in somehow?
