Downloading All Zope products
by Jerome Alet 12 Jan '01

12 Jan '01

Hi, I was bored by the current search interface for downloading Zope products: you have to spend hours just clicking to download lots of products. I want to put Zope and the maximum number of available products on a CDROM to be able to do demos and so on to people not connected to the Net. I've decided to do something to solve this problem, so I've created the "Zope Complete Products List for easy batch download". You can find it at http://www.zope.org/Members/jerome/ZCPL This document dynamically lists all available Zope products (from zope.org) and for every product put one and a single link to its latest version archive. It also explains how to download all Zope products available in one Wget run, but please consider not making this an habit because the DC folks don't seem to like that (see http://www.zope.org/robots.txt) DC folks, if you find this document should be destroyed now then just do it, I don't want to put your servers on their knees. Hoping this will help someone else. Any comment is very welcome. bye, Jerome ALET - alet(a)unice.fr - http://cortex.unice.fr/~jerome Fac de Medecine de Nice http://wwwmed.unice.fr Tel: (+33) 4 93 37 76 30 Fax: (+33) 4 93 53 15 15 28 Avenue de Valombrose - 06107 NICE Cedex 2 - FRANCE

RE: [Zope] Zope vs. java solutions : looking forward ?
by sean.upton＠uniontrib.com 12 Jan '01

Frankly, it is a lot easier to program in python; it is much more forgiving in a lot of senses. If your developers like the idea of Java because it is OO, have them consider python's strong abilities, and the fact that they will be working with a persistent object system / ODB that can make their OO code much more than a filter for relational datasets. That said, if your developers like java because it runs in a VM on several platforms, Zope is cross-platform, and I guess Zope could be considered similar to a JVM: a platform for running cross-platform code. I don't think Java is a wise direction for a small firm; at least in Zope, you can start off with simplicity, and graduate to bigger solutions without a huge investment in lots of developers in the future. What kind of site do you have? For e-commerce, you are going to have heavy use of relational databases, but for publishing articles, you might want to consider using the ODB, something you are not going to get with Java solutions... I use Zope with XMLDocument and custom ZClasses for content, and it is a lot easier to get things done quicker that way...

Hi, We are planning a major update of our site (i.e. building a new one). At the moment our site is based on php,cgi, MySql and Apache on Linux. However, for the new site, we are considering other 'platforms' like Zope or Enhydra. I find Zope an elegant solution for our new site because we will be relying heavily on non-technical people contributing articles for publication. But the problem is this : the development will be made by a small commercial firm (the guys who work there are friends) and they are biased towards a java solution because they think this will be a standard for the future. They do not want to invest in learning Zope en end up in not being able to sell their acquired knowledge in this. I should note that, at the moment, they have no experience in Java nor Python, so they will have to learn one or the other. The problem I will be facing is the maintenance of the site and adding new features. What do you guys think ? Does Zope have a future with respect to e.g. Enhydra (this is Python versus Java for internet applications)? Does someone have experience with both and can you comment on the learning curve ?

Authentication problems on FreeBSD with Apache
by Drew Sanford 12 Jan '01

12 Jan '01

I have recently installed Zope on FreeBSD running the Apache web server. When I attempt to access the management page from http://my.web.server/cgi-bin/Zope.cgi I get authentication failures. I'm sure there are things that I've missed in what I've seen, and the section on running Zope with Apache in the manual isn't done yet. Can anyone point me towards some of the known issues here as far as what someone clueless about Zope but reasonably familiar with Apache might need to do to get authentication working?

If you store the path to the other object as an attribute on its referer, then you can use the OFS.Traversal interface to fetch the referred object on demand. E.g.:: class Foo: bar_path = None def setBar( self, bar ): """ Save bar's path so we can find it later. """ if bar is None: self.bar_path is None else: self.bar_path = bar.getPhysicalPath() def getBar( self ): """ Use stored path to retrieve bar. """ if self.bar_path is None: return None return self.restrictedTraverse( self.bar_path ) # ^_could be 'unrestrictedTraverse', in trusted code Tres -- =============================================================== Tres Seaver tseaver(a)digicool.com Digital Creations "Zope Dealers" http://www.zope.org

hasRole bug or feature in 2.2.?
by Ron Bickers 12 Jan '01

12 Jan '01

I'm having a problem with AUTHENTICATED_USER.hasRole() I have a user with the role 'Member' defined at the root level (and nowhere else). I also have the following DTML method at the root level: <dtml-if "REQUEST['AUTHENTICATED_USER'].hasRole(PARENTS[-1], ['Member'])"> You are a Member. <dtml-else> Your are NOT a Member. </dtml-if> When I first request the protected document /Bogus/membersonly, I'm prompted to log in. When I do, I get access to the /Bogus/membersonly document. Then when I request /Bogus/isMember, it says I am a Member. However, when I request /isMember, it says I am NOT a Member. Anywhere I request isMember, other than in the /Bogus folder, I am NOT a Member, even though the user is defined at the root level with the Member role. If I then request a protected document /membersonly, it shows me the document without prompt. After I do that, when I request /isMember or /AnyFolder/isMember, it now tells me I am a Member. Why does it not recognize that I'm a user with the Member role anywhere on the site until I access a protected document at the root level? Is this by design or a bug? If by design, what's the reasoning? Thanks! _______________________ Ron Bickers Logic Etc, Inc. rbickers(a)logicetc.com

document_src not doing what I thought it did
by Tim Hicks 12 Jan '01

12 Jan '01

I have a dtml-documentish zclass and have created a custom edit method for it so that I can do an automatic reindex when each instance is edited. I created this custom form by simply copying the source html that is generated for the standard edit form, and then replacing the static parts of what I copied with various <dtml-var > inserts (see below). This seemed to go according to plan until I realised that something strange is happening when I try to view this edit form for an instance of the zclass. In most cases, everything seems normal, but when I try to edit an instance that has a property set to 'private', my 'privacy' method kicks in and redirects me away from the edit form to my standard 'Restricted Page'. The redirection is written into the text of the instance I am trying to edit, so I expected that by using <dtml-var document_src>, the actual source would get placed in the text area without being processed. This is what appears to happen when the instance does not have the 'private' property. I guess therefore, my question is, am I using document_src correctly? thanks very much tim ps Sorry to be such a regular poster of problems <FORM ACTION="my_edit" METHOD="POST"> <TABLE CELLSPACING="2"> <TR> <TH ALIGN="LEFT" VALIGN="TOP">Id</TH> <TD ALIGN="LEFT" VALIGN="TOP"><dtml-var id></TD> </TR> <TR> <TH ALIGN="LEFT" VALIGN="TOP"><EM>Title</EM></TH> <TD ALIGN="LEFT" VALIGN="TOP"> <INPUT TYPE="TEXT" NAME="title" SIZE="40" VALUE="<dtml-var title>"> </TD> </TR> <tr> <th align="left" valign="top"> <em>Size</em> </th> <td align="left" valign="top"> <dtml-var get_size> bytes </td> </tr> <tr> <th align="left" valign="top"> <em>Last modified</em> </th> <td align="left" valign="top"> <dtml-var bobobase_modification_time> </td> </tr> <TR> <TD COLSPAN="2" ALIGN="CENTER"> <TEXTAREA NAME="data:text" WRAP="Off" COLS="115" ROWS="25"><dtml-var document_src></TEXTAREA> </TD> </TR> <TR> <TD align=left> <INPUT NAME=SUBMIT TYPE="SUBMIT" VALUE="Change"> </TD> <TD align=left> <INPUT NAME=SUBMIT TYPE="SUBMIT" VALUE="Taller"> <INPUT NAME=SUBMIT TYPE="SUBMIT" VALUE="Shorter"> <INPUT NAME=SUBMIT TYPE="SUBMIT" VALUE="Wider"> <INPUT NAME=SUBMIT TYPE="SUBMIT" VALUE="Narrower"> </TD> </TR> </TABLE> </FORM>
