You need place .zope_autostart script (attached below) in your home directory (don't forget make this as exetutable :). Also in your crontab file you need place a line (through command: crontab -e) like this: 0,minutes_between_checks * * * * /home/your_home/.zope_autostart zope_dir notify_email eg: 0,30 * * * * /home/jasonic/.zope_autostart /home/jasonic/Zope jasonic(a)nomadicsltd.com For me, works well. PS: I'am not good familiar with Linux (ang English lang too...) and you must ask anyone else if you would have troubles with access to crontab, advanced Linux configurations etc...

GUF question
by Mabe, Brad 17 May '00

17 May '00

Hello all, I recently downloaded and installed GUF and am having a strange problem. I followed the walkthrough and successfully created a folder that only the user "jorge" can access. Thinking life was good at that point, I decided to try and add additional GUF users and give them access to the protected folder. I made the appropriate additions to the userAuthenticate, userList, and userRoles methods (the dtml methods found within the acl_users folder) and was unable to log in and access the protected folder as anyone other than "jorge". I then decided to backtrack a bit and removed the modifications I had made, and verified that "jorge" could still log in and access the folder. I then renamed "jorge" to "bama" in the above GUF dtml methods, restarted the Zope server (I am running NT, after all ;-) ), and was unable to log in as "bama". For the heck of it I tried to log as "jorge". No dice. I then renamed "bama" back to "jorge" and was again able to access the protected folder as "jorge". Obviously I am missing something. Shouldn't I be able to add users to the provided GUF dtml methods? And why the heck couldn't I simply rename "jorge" to "bama"? -=Brad=-

Zwiki extension work - stuck changing new properties
by Geoff Gardiner 17 May '00

17 May '00

Sorry for a slightly lengthy post - hope this is the right list. I'm trying to extend Zwiki functionality, and have got quite a long way with what I want - basically restricting some users to append-only in certain circumstances. However, although I can create the new properties, I'm not able to access them in the edit method and I don't see what I should be doing. Other properties seem to be accessible, but not my new ones (although they are visible in the properties tab, and can be read Ok). I have tried appending 'self.' but this just comes up with an error telling me that they don't exist. The fragments below are all that I have added to the Zwiki product (see the geoffg comments below for what I've done), but I've got some additions to zwiki.zexp as well to provide forms input. Thank you again for any and all help, Geoff Gardiner In ZwikiPage.py .... class ZWikiPage(DTMLDocument): #, CatalogAware): """A ZWikiPage is a DTML Document which knows how to render itself in various wiki styles, and provides some utility methods to support wiki-building.

Ok - probably the best way to do this is to have frmAddUser include a hidden field in the form, a la: <input type="hidden" name="go_back_to" value="<dtml-var HTTP_REFERER>"> When the form is submitted, the form handler can then do the redirect to whatever the value of "go_back_to" is.

But how can I return to the second last page with a RESPONSE.redirect? If I use <dtml-call "RESPONSE.redirect(HTTP_REFERER)"> a call will be redirected to my calling form. E.g. I want to have management screens for the users with that they can add instances of things. I have put the forms that will be used to get necessary information in a subfolder, say /Forms and ZSQL Methods in another subfolder /SQL. So this will result in the following calling sequence: .../frmAManagementScreen -> /Forms/frmAddNewUser -> /SQL/sqlAddUser After adding a user by /SQL/sqlAddUser I want to return to .../frmAManagementScreen and NOT to /Forms/frmAddNewUser. But a <dtml-call "RESPONSE.redirect(HTTP_REFERER)"> in /SQL/sqlAddUser (which is the last in the calling sequence) will return to /Forms/frmAddUser. (.../frmAManagementScreen can have an arbitrary location within my hierarchy.) I am looking for an (elegant) way to do this.
