Disappearing data?
by Chris Larson 11 Feb '99

11 Feb '99

I finally got Zope up and running, and started working my way through the Plutonia quick start in the ZMG. Made a few changes, saved them by clicking on the change button. I had added three folders, changed a couple of items, then left for about 4 hours. When I got back, I started looking again, clicked on the properties tab, added a date property, clicked on change, and got a message back saying roughly that the data didn't exist. I clicked on reload, and was rewarded with essentially a virgin installation. That is, everything I had changed or added was gone, and the data visible was just what I saw when I first started. One of the first things I had done was make the standard background color "FFFFEE" instead of "FFFFFF". Even that had reverted. What's the deal here? Am I missing some login/logout or confirm changes this session option? Chris Larson

Variable setting in 'if' for use outside of 'if'
by Shaw, Howard 11 Feb '99

11 Feb '99

Is there any means of setting variables other than 'with'? As best I can determine, the mechanism for setting variable using 'with' provides those values only within the 'with' block. I would like to preface my html with an if-elif-elif-else block, using it to set a variable so that a simple if-else test can be used later on. I would prefer not to have to replicate the full document within each portion of the if-elif-elif-else block, but I can't find a way to set a variable in the if-elif-elif-else block that can carry over to the rest of the document, since Zope considers it an error for a tag to be only partially contained within a larger block. Please help.

Problems with File upload and Zope-1.10.0pr1
by Pavlos Christoforou 10 Feb '99

10 Feb '99

Hello Zopistas Part 1 Trying to upload a plain text file, name Test into Zope (as an object File), (both Zope-1.9.0 and Zope-1.10.0) results in the following error: Sorry, an error occurred. Traceback (innermost last): File /home/pavlos/Zope-1.9.0-src/lib/python/ZPublisher/Publish.py, line 879, in publish_module File /home/pavlos/Zope-1.9.0-src/lib/python/ZPublisher/Publish.py, line 595, in publish (Info: /manage_addFile) File /home/pavlos/Zope-1.9.0-src/lib/python/OFS/Image.py, line 124, in manage_addFile (Object: ApplicationDefaultPermissions) File /home/pavlos/Zope-1.9.0-src/lib/python/OFS/Image.py, line 180, in __init__ (Object: PropertyManager) BadValue: No content type specified Image.py in Zope 1.10.0 has a more intelligent way to figure out the type but they both fail. I cannot see how the PUT function of Image.py (Zope-1.10.0p) can fail to set the content-type. Part 2. I have installed Zope 1.10.0 and transfered the old Data.bbb files in the var directory. Everything seems to work ok and the old Document objects have been succesfully changed to DTML method objects. Nevertheless a dtml like:  captures only the old Documents and not the new DTML methods or DTML Documents that I have added. Curiously copies of the old Document methods are also not shown. Looks like a bug to me. Pavlos

WHERE {existing stuff} AND team =  All of the interesting stuff could still go in /top and be acquired into each Team folder. We've done that in a number of cases... </untested> As I look at this though, it sounds more like you might want to use roles... Make Team1, Team2, and Team3 roles and assign them as such in the user table. Then you can use organic security/permissions... What did you want to do with the list of Team1 members? --Rob

Newbie question (Adding objects)
by Haldeman, Kurt P 10 Feb '99

10 Feb '99

I got Zope up and running with Netscape 3.5.1 on a Sun Solaris 2.6 box. When I run it (via the web interface) and try to add something, be it a document, a folder, etc., (using the pulldown and "Add" button) I get the same message: Not Found The requested object does not exist on this server. The link you followed is either outdated, inaccurate, or the server has been instructed not to let you have it. Please inform the site administrator of the referring page. The link is along the lines of: http://my.server.com/cgi-bin/zope/Zope.cgi/.?%3Amethod=manage_addDocumentFor m I don't get any error in my error log, I have debug=1, and I don't get any errors in the Zope log file. Any clues? Kurt P. Haldeman Web Engineer Storage Technology Corporation kurt_haldeman(a)stortek.com (303)673-4176

What happens to acquisition when creating new permissions?
by Andy Smith 10 Feb '99

10 Feb '99

Hi All, I'm in the middle of changing the security handling on the Guestbook product I submitted to the site not too long ago. I now have a situation where I have a product (Guestbook), which adds and manages sub-objects (GuestBookEntry). The permission 'Add Entry', instead of being a permission of the enclosing folder, is now a permission associated with the Guestbook. In the manage screen, a newly-created product instance has the 'Acquire' box set, but doesn't have the 'Add Entry' permission granted to any roles ('Anonymous' or 'Manager'). When the acquire box is ticked, I can add entries in a fresh browser without having to enter any authentication info, even with no roles granted the appropriate permission, so it seems as if the 'Add Entry' permission is being acquired from somewhere, even tho no-one further up the chain has this permission to acquire. If I deselect the 'Acquire' box, I'm now get the authentication dialogue when I try to add entries, and I have to grant the 'add entry' permission to diferent roles if I want them to add entries. (i.e. this is the behaviour I was kind of expecting when the acquire box was checked!). Cheers, Andy.

UserDb
by Ross J. Reedstrom 10 Feb '99

Yes, I know that this is an "unsupported, don't ask us questions about it" product. so you offical types at Digital Creations ignore this message. I'm talking to the other users out there who've been playing with this as well, and have more python/Zope experience than I do. In particular, I like the ability to validate against my db. However, I'm wondering if there's some clever method of overriding the SQL methods used by UserDb, short of 'cut&paste' code reuse to make myUserDb. See, I've already got tables & fields with usernames and passwords, but I need different queries to access them. Ideally, I'd like to overide a particular _instances_ methods - so, for example, I can have users in different Teams, and return only the users that exist in a particular team. Any bright ideas out there? Is this another something obvious that I failed to grasp, any you're all now laughing at me? Ross -- Ross J.

Re: [Zope] DTML calendar widget

That what happens when you get Ty and me together... I complain a lot and tell Ty what I wish I had, and Ty goes away for a few hours and comes up with these jewels. :^) Actually, Ty said he had been thinking of it already, but he's gonna have to learn not to tell me that kind of information because I'll begin to question his zenhood. My suggestions were to provide a mechanism for managing a calendar 'wrapper' which could hold or reference other objects. I.e. you could either drop other Zope objects into a date or point at them somehow. Ty came up with the dtml extension to manage the calendar but we aren't quite sure how to hook things into it. Were hoping to get some suggestions. Also there's the question of 'look'. How much flexibility is needed in customizing the 'look' of the calendar? Is it just easier to take an example and write your own or is it worth it to try to build an editable folderish calendar product? What for? Well, I'm tasked with wrapping up the whole population genetics department into a publishable object where I just hired on, including all the genetics databases, management statistics and department scheduler sorts of things. They said they'd understand if it took me a while. :^) I'm mainly wandering around looking for ideas on how to cause trouble right now... I gave a talk on three of the projects I've worked on the last year and mgment's (I get to work with intelligent monkeys at this job :^) eyes lit up and they got all excited. So please give Ty some more ideas for this calendar thingy! How would you use it? what sorts of things would you want it to contain? Kent
