Zope 2.5.0 acl_users encrypt passwords lock users out!
by Jurasurf＠aol.com 30 Jan '02

30 Jan '02

Using the property tab of acl_users, a strange behaviour occurs, which I could reproduce on Linux and Windows boxes. If you choose password encrypting and save all users in this folder get encrypted passwords and no one of these can log in anymore ... this seems rather fatal if the administrator thinks he could improve security but in fact just locks out the site members. Any idea? Urgently hoping for help.

It works fine for me... -----Original Message----- From: Michael Montagne [mailto:montagne@boora.com] Sent: Wednesday, 30 January 2002 8:10 To: zope(a)zope.org Subject: [Zope] Products I thought you could go to http://www.zope.org/Products and be presented with a list of bunches of available products arranged by category.

Migrating standalonge applications to Zope
by Nicolas Rodriguez 30 Jan '02

30 Jan '02

First of all I'll like to thank you all for all the info I got from this list in the past two months. I'm currently migrating a lot of standalone software I had made to Java and I REALLY don't think the complications that the language dictate help me at all. Thanks to this experience I resume my evaluation of Zope and I found out that this enviroment may be better for me to use. I realise that in Java I spend three to five times more effort that I did in Visual Basic (for example). Does anybody migrate/rewrite/build any "classical standalone" application in Zope (accounting, payroll, data acquisition application, etc)? How much effort did this took? I appreciate any comments. Thanks in advance, Nico.- PS: Sorry about my english!

Creation of objects inside folder like products
by Tille, Andreas 30 Jan '02

30 Jan '02

Hello, I'm busy writing some folder like product with special features. The last thing I wanted to add is a TinyTable which is created when the the FolderProduct is created. Here is some stripped down code: MyFolder.py: link_list='''<dtml-comment> ... </dtml-comment>''' column_names='Link Frame Text' ## ........ if createSelection: if not checkPermission('Add Documents, Images, and Files', ob): raise 'Unauthorized', ( 'You are not authorized to add DTML Documents.' ) ob.manage_addMyDocument(id=ob.id+'_sel.htm', title=ob.id+' left navigation frame', author=ob.author, content=frame_sel) # ob.manage_addMyDocument(id='link_list', title='List of Links for '+ob.id, # content=link_list) ob.manage_addTinyTable(id='link_list', title='List of Links for '+ob.id, columns=column_names) There are two lines commented out from the previous version when I just tried to solve the problem with a DTMLDocument like object. The creation worked perfectly. Now I wanted to add a TinyTable instead of the DTMLDocument like product. Unfortunately this TinyTable will not be created inside MyFolder but inside the nearest (real) Folder object. For instance <Folder 1> -----------> <MyFolder 1> -----------> <TinyTable link_list> If I try to create <MyFolder 2> inside <MyFolder 1> I get: <Folder 1> -----------> <MyFolder 1> ------------------> <MyFolder 2> -----------> <TinyTable link_list> provided that I removed <TinyTable link_list> before or just moved <TinyTable link_list> from the first try just inside <MyFolder 1>. That means MyFolder could perfectly contain <TinyTable link_list>. It ist just not created inside the MyFolder object. The same is true for TinyTablePlus. Quoting from the source of TinyTable[Plus]: def addItem(self, id, title='', columns='', REQUEST=None): """Add a TinyTablePlus to a folder The argument 'self' will be bound to a folder. The arguments, 'id' and 'title' are minimal, and most applications will have additional needed arguments. """ self._setObject(id, TinyTablePlus(id, title, columns)) if REQUEST is not None: return self.manage_main(self,REQUEST) Does this mean that the addItem Method just searches the object tree down to the next (real) folder object? What do I have to do that TinyTable accepts MyFolder as object to be addable to? Kind regards Andreas. PS: I hope I did not stripped down my code to much to hide the real problem.

please wait message or partial page display
by Jerry McRae 30 Jan '02

30 Jan '02

Hi Zopeople, Is there a way to display a partial screen with a 'please wait' message? Then display the remainder or redirected screen after it is rendered? I want a message that tells users it could be 20-30 seconds before the next, complex screen displays. The example in the Zope Book (in advanced DTML) looks simple enough, but it doesn't display ANYTHING until the redirect is finished. The closest I could find was RESPONSE.write('a string'), but that disabled the following REQUEST.redirect and all the other HTML in the screen. I want a simple 'please wait' message or to show part of of page while the rest is rendering. Someone else must want something like this, or has done something like this. I have searched everywhere to no avail for terms: partial, delayed, refresh, timed, redisplay, pop up, pop-up, HTTP, headers, flush. --Jerry /\_/\ Jerry McRae \|||/ mail safely: The Bat! 1.53d (~o o~) (stuck in win98) (. .)

Ugly JS hacks incorporated: Making a web page that looks for the server.
by Lennart Regebro 30 Jan '02

30 Jan '02

This little script will try to connect to the localhost:8080 server. When it succeeds it will open http://localhost:8080/ . So, you don't get an error page if the server isn't started. It will just go on trying until the server is there, and then open the page. A script like this will be included in the distribution of our content management system. Now, how does this work? It's simple, it's ugly and it's almost funny. It loads http://localhost:8080/ into an iframe 1x1 pixels big, and then waits 5 seconds. Then it checks if the iframes location.protocol is http. And if it isn't, I try again. The thing is, that when IE5.5 succeeds in loading the iframe, the iframes location *does not have a protocol property*. Hence, if the fram *is* loaded, the test will throw an exception, in which case I open the page. *Tada!* I feel like sharing this horrible ugliness. Here you are: <html> <head> <eta http-equiv="Refresh" CONTENT="5"> <title>Locating EasyPublisher Server</title> </head> <body> <p>Waiting for server to start...</p> <iframe name="newFrame" height="1" width="1">   </iframe> <script language="JavaScript"> function check() { try { if (newFrame.location.protocol != 'http:') { newFrame.location = 'http://localhost:8080/'; setTimeout('check()', 5000); } } catch(e) { document.location = 'http://localhost:8080/'; } } newFrame.location = 'http://localhost:8080/'; setTimeout('check()', 5000); </script> </body> </html>

Re: [Zope] id of an externally created object
by Stephan Zaulig 30 Jan '02

30 Jan '02

Yes, I used _setObject. The object is created correctly, but without using the _setId method I can't get the id, although in the management interface of Zope the id appears.

PersistentList is missing
by Thomas Guettler 30 Jan '02

30 Jan '02

Sorry if me or grep is blind but I can't find the class PersitentList in the sources of Zope2.5.0: cd zope/lib/python; grep -irs persistentlist * --> no result http://www.amk.ca/zodb/guide/node38.html and other sources tell me that there is something like this in ZODB. Has Zope just a subset of the available classes of ZODB? thomas

How to hook __before_publishing_traverse__
by Sidnei da Silva 30 Jan '02

30 Jan '02

Reading the documentation, i found out why i could not set permissions on the before_publishing_traverse. It seems that at this point, getting SecurityGetUser its not reliable. So, i was thinking of a way to test for if a role is valid to access an object. Maybe Security.validate() or something, i dont know. And if theres a hook for testing when a property is accessed, like testing for some condition before returning title_or_id. Something like __before_property_access__. Thanx. -- Sidnei da Silva X3ng Web Technology sidnei(a)x3ng.com.br

30 Jan '02

Using Zope 2.5 beta 1. I followed the automatic cataloging example in the Zope book. Yes the first class is CatalogAwareBase ZObject, CatalogAwareBase, ZDTMLMethod Catalog indices are text indices set to one two three Catalog metadata is set to one two three Catalog find_object is set to my_aware_object my_aware_object properties are one two three Yet when I add a new instance of the my_aware_class the catalogue is not updated. What am I missing, Chris
