user folder question
by ben＠thesite.org 10 Dec '02

10 Dec '02

I'm having a problem with user folder permissions: I have one acl_users folder at the root folder of a website, www.mysite.org, using Cookie Crumbler I also have an acl_users folder in parallel to this, allowing access to an XML-RPC application server area. I need to keep them separate, or failed XML-RPC authentications are picked up by the Cookie Crumbler code, and the XML-RPC client gets the login_form html page sent back! I need to let certain users of the website create user accounts in the xml-rpc server area. I have a user role, hq_user, who creates the user in the xml-rpc area. The permissions on the xml-rpc root directory grant hq_user the manage_users permission. But when I try to add users in this other acl_users folder, I get an error that it is not allowed. But this user, if I change the code, can create users in its "own" acl_users folder. The hq_user role is created in the root directory above both the acl_users folders in question. the python code: context.xmlrpcfolder.acl_users.userFolderAddUser(name=f_username, password=f_pwd, roles=['c_lcp'], domains=()) can anyone shed light on this? what permissions do I have to set to add a user to an acl_folder? TIA Ben Avery (zope 2.6.0, pyth 2.1.3, solaris 2.7)

ZODB / SQL question
by Michael 10 Dec '02

10 Dec '02

Is there some documentation on how to migrate from an existing ZODB application to SQL? I seem to only find info on setting up and using one or the other, but now how to switch from one to the other. Any pointers would be appreciated. Michael

dynamic resize of image?
by Kelley, Sean 10 Dec '02

10 Dec '02

I have some images in a btree folder that get added by users. How do I show those images in a smaller size easily on a search results page? It would be nice to some way specify the default size in width such as 50 pixels etc.

Paul, If I had not figured it out myself at about the same time you were writing your reply, you would have saved my evening! Thank you very much! I hope I speak for all of us in need of help on this list in thanking all of you Zope masters for taking the time to answer our questions.

ZPT standard_error_message not finding methods
by Felix Ulrich-Oltean 10 Dec '02

10 Dec '02

Hi I'm trying to write a standard_error_message page in ZPT and attach it to my class. In my class definition I have: standard_error_message = PageTemplateFile('html/error_page.html', globals()) and manage_master = PageTemplateFile('html/master_page.html', globals()) in error_page.html I have: <p tal:content="exists:container/manage_master" /> Now, this returns true: http://localhost:8080/sites/myClassInstance/standard_error_message but this returns false: http://localhost:8080/sites/myClassInstance/some_nonexistent_page There are also other methods that are found when calling standard_error_message explicitly, but not when it's called as a result of an error. What am I missing about how standard_error_message is called? TIA Felix.

TAL that kills
by David Bear 10 Dec '02

10 Dec '02

Interesting problem. IN a ZPT the following TAL will always kill the Zserver processes. <p tal:repeat="doc container/docStore"> <a tal:attributes="href doc/getId" tal:content="doc/title_or_id">document </a> </p> any idea why? This is Zope 2.5.1 running on python 2.1.1 on FreeBSD. I've done a littl tal and none of it has caused zope to die like this.

Hi folks, this mail is intended for Peter Bengtsson, the author of issuetracker, but his systems seems to have problems.

Re: [Zope] Best practices to write business apps?

(I combined the two posts into one) On ... , Paul Winkler wrote: >I wouldn't say that DTML is evil... simple DTML is very nice, >it's just that *abuse* of DTML is evil and it's always tempting >to add just "one more thing" instead of breaking it out into >a script. And you can abuse ZPT pretty easily, too... I agree, but IMHO, the Zope Book shouldn't start with DTML right from the beginning because it'd be easier for developers who come from traditionnal environments (ie. not web apps) to jump right in. Instead, it should show right from the beginning how to separate logic and presentation, just like ASP.Net does. Much less confusion :-) >The "Advanced Scripting" chapter in the online Zope book is a decent >introduction to this kind of thing, although it's a lot more >nuts-and-bolts than best-practices. Yup, read that last night. >Since you say "procedural languages", I suspect what you >really need is to read this: >http://www.zope.org/Members/mcdonc/HowTos/gainenlightenment Indeed, read that too before posting. A must-read for Zope newbies. +++++++ On ... , Dylan Reinhardt wrote: >But I would encourage you not to make a payroll system your first major project... I agree wholeheartedly. Unfortunately, my dad's software in VB, which I intend to take over as he retires, is a total mess.

I have already purchased "Learning Python", and will read the ZDG today. Combined with the New Riders book and possibly the (Zope) Bible, I should be able to build a prototype. >At the point where you're weighing issues more technically nuanced than >whether DTML is evil (it isn't), I think you'll probably find a lot of help >available for any ambitious projects you may be ready to take on. The "DTML is evil" was a reference to one of the articles I found on Zope. Actually, as explained to Paul, I think it'd be a good thing to write an introduction to developers who come from procedural programming and don't know anything about web apps. My brother is heavy into ASP.Net, and I must say it's very nice because it separates logic and layout right from the beginning. As an introduction to web development, it's pretty good, but I'd rather use a non-proprietary tool. Thx much to both of you for your input :-) Fred.
