DTML on Linux client
by Stephan Goeldi 10 Nov '00

10 Nov '00

I checked my website www.goeldi.com with a SuSE Linux 7 client (Netscape) and discovered, that not all DTML is done right. My index_html file has: <dtml-var standard_html_header> Welcome to our website. <dtml-var actual> <dtml-var standard_html_footer> The header and footer are displayed correct. The welcome text of the index_html file too. But the dtml-var actual is not displayed at all. The text browser lynx has the same problem under linux. I tried it from a RedHat 6.2 system with lynx -> same problem. The page is displayed correctly with any Windows browser. What's going wrong here? _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Is data.fs corrupted?
by Alexander Chelnokov 10 Nov '00

10 Nov '00

Hello All, After a linux machine crash or cold restart something strange is going on with Zope (2.2.2) - all objects built on ZClass-based products like Yihaw or QSurvey are broken. Products are in Product folder, and i even can add an object and it works, but when i try to access it in a new browser window it reports ========== This object is broken because the unknown product that created it is no longer installed or is installed incorrectly. Please contact your product vendor for assistance. Note that the data associated with this product has not been lost, and will be accessible again if the product is reinstalled. ========== Well, i removed QSurvey and tried to re-install its current version - something goes wrong again: ========== Zope Error Zope has encountered an error while publishing this resource. Error Type: Could not load oid ={, pickled data in traceback info may contain clues Error Value: None ========== Is there any way to fix ZODB less radical than complete reinstall? -- Best regards, Alexander N.

don't know about inside zope, but in plain python you could just do: new_options = list(options) perhaps an external method would cut it: return list(inputstring) -- Geir Bækholt web-developer/designer geirh(a)funcom.com http://www.funcom.com on Friday, November 10, 2000 Tony McDonald wrote : TM> Hi all, TM> Say I've got a form with this in it TM> <select type="checkbox" name="options:list"> TM> <option value="1">number 1 TM> <option value="2">number 2 TM> <option value="3">number 3 TM> </select> TM> When this is put into an SQL database, the field 'options' is this (string) TM> ['1', '2', '3'] or ['2', '3'] etc. TM> When I get the data back from the database, 'options' comes back as a TM> string, and <dtml-in options> ... </dtml-in> gives errors (basically, TM> it can't iterate over a string).

Hi all, Say I've got a form with this in it <select type="checkbox" name="options:list"> <option value="1">number 1 <option value="2">number 2 <option value="3">number 3 </select> When this is put into an SQL database, the field 'options' is this (string) ['1', '2', '3'] or ['2', '3'] etc. When I get the data back from the database, 'options' comes back as a string, and <dtml-in options> ... </dtml-in> gives errors (basically, it can't iterate over a string). I tried <dtml-call "REQUEST.set('new_options:list', options)"> and then tried iterating over new_options, but the variable didn't exist... Has anyone got any solutions for this?

How do I set the Title property of a File object from a DTML method
by magnus＠websys.no 10 Nov '00

10 Nov '00

I have some of my own ZClass objects that may contain other ZClass objects or Files. Using a form and a method (that calls manage_editProperties(REQUEST)) I can set all the properties of my own ZClass subobjects. But I'm unable to set the Title property of a File object. Is there a secret trick? -Magnus

I'm curious, you posted a message about SiteAccess. I have the same problem, with Debian (Zope 2.2.2 and I've tried SiteAccess 2.0.0b3 and b4). It producing the same errors you have, but in addition, I have this info from the stupid log file: 2000-11-09T20:09:18 ERROR(200) Zope Couldn't install SiteAccess Traceback (innermost last): File /usr/lib/zope/lib/python/OFS/Application.py, line 488, in install_products (Object: ApplicationDefaultPermissions) (Info: SiteAccess) File /usr/lib/zope/lib/python/Products/SiteAccess/__init__.py, line 12, in initialize File /usr/lib/zope/lib/python/App/ProductContext.py, line 323, in registerHelp OSError: [Errno 2] No such file or directory I have no idea what's going on, and any help from you or the zope mailing list would be appreciated.

RE: Zope digest, Vol 1 #1049 - 28 msgs
by Harris Peter 10 Nov '00

Hi all I am strugging with accessing acl_users from DTML, and maybe someone here can tell me what I'm doing wrong. I am trying to make a page where users can change their own passwords. I have a DTML document with "Manager" proxy role. It is a form that lets the user enter "password" and "confirm" and contains a hidden field for "name" taken from AUTHENTICATED_USER. It has a submit button with value "Change", and in all respects, as far as I can tell, should post in the same way as the corresponding form in acl_users.manage_users?submit=edit It posts to itself, where I do this: <dtml-if "REQUEST_METHOD=='POST'"> <dtml-call "REQUEST.set('roles',AUTHENTICATED_USER.getRoles())"> <dtml-var "acl_users.manage_users(REQUEST=REQUEST)"> </dtml-if> I don't get errors, but the password is not changed, and I can't see why. Has anyone ever got this sort of thing to work? And if so, how?

acl_users API
by Harris Peter 10 Nov '00

10 Nov '00

Hi I have given up trying to manipulate acl_users from DTML for now - I'm sure it's possible because here and there on this list and on the Zope site I see hints that it can be done. However, I can't find (for example) a HOWTO anywhere that describes the API of acl_users and what you can do with it. Someone out there must do this sort of thing all the time, so don't be shy, write that HOWTO! (Or if I'm being really thick and there is one, just let me know where it is!) Failing that, maybe someone can suggest where to look in the Zope python source to find the methods acl_users exposes.

security dilemma?
by Zhen Zhou 10 Nov '00

10 Nov '00

please bear with my ignorance, because this is the first couple of day I ever try Zope. It is super cool, but I should say that the documentation is far from satisfaction. Here is my problem: The only API I can find to alter the properties of some object is "manage_changeProperties". However, in order to execute this method in my script, I have to give the "Manage properties" permission to everyone, which may lead to severe security problems because the method "manage_changeProperties" is web accessible, so a malicious user can bypass my script and execute this method to change the properties to whatever he want. My questions are: 1, is there any API that can change properties of some object but can not be accessed from the web? 2, is there any way to store a small piece of persistent data beside using properties? Thanx. Derek
