Returning results from pythod method to web page
by alankirk 16 Mar '01

Hi there, I'm trying to find a way of returning some results from a MySQL database search into a <OPTION> </OPTION> list in a web page. I've written a python method which gets all the data i need from my database. I've stripped down the results (ie removed all the double and single quotes) so i can split them into the individual results. Heres my problem, i've got a while loop that will loop through each of the results from my database query, but i need some way to pass these results out to my web page. I've tried using: while (i<length): return " <option value=\" "+splitString[i]+" \">"+splitString[i]+" " i = i + 1 Which works but as it uses Return it fall out the loop and only returns the one item in my OPTION list. So i then tried to return a string of all the search results such as: while (i<length): f = " <option value=\" "+splitString[i]+" \">"+splitString[i]+" " i = i + 1 s = f s = s + f return s which returns the last item of the seach results. I've worked out that it does this because i keep overwriting the value of s with f. I've tried to assign s to be empty or " " but i was getting error messages saying s has not been assigned any values. Does anyone know how i could get around this? or does anyone know a better way of returning values from a loop into a web page?? Any feedback (preferably ASAP) would be most apprieciated Cheers Alan

FTP lost Titles
by Stephan Goeldi 16 Mar '01

When I transfer my locally (WinNT Zope 2.3.0) created DTML files, to the remote webserver (RedHat Zope 2.3.0), the DTML files are transferred correctly except of the titles. There is no title anymore on the remote machine. Did I miss something? _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

You can store your data in any external DBMS (I use PostgreSQL). But the Zope objets have to be in the ZODB (I've seen discussions about storing them in the external DBMS, like OpenInteract or Enhydra do, but, AFAIK, there is no easy way to do so at the present time. Zope is quite closed.) > - vi compatability :) I haven't yet found out where the actual files > reside, /var/lib/zope/Data.fs > but one thing I do *not* want to use for regular development is > the web frontend.

The ZODB can be reached with FTP or WebDAV with limitations (versions, some types of objects...). Any FTP-aware editor (I use Emacs and HTMLkit) can do it. As mentioned, the Linux (and only Linux) FTP filesystem (experimental) can be used to enable you to access Zope objects with any Unix tool.

bottleneck?
by Tom Deprez 16 Mar '01

16 Mar '01

Hi, I need to build a intranet site in which we'll store all references (like author, date, title, ...) to written articles, thesisses, publications, books, .... from our department. The problem is that all these different mediums contain much the same information except for 3-4 fields.I could put all this information inside an sql database. However, it might be interesting to also actually store for instance the whole article... Then I think I better store everything inside Zope. But, I'm wondering if Zope can handle much data in a same folder. For instance, I would like to store all publications inside a folder named publication. But this would lead to a lot of publication objects in one folder... Can Zope handle this? Or are there better methods to achieve this (which I can wonder, since Zope was first build for newspapers which want to show there contents on-line). How do you do such a thing? Thanks in advance, Tom.

Re: uploading file with python script (problem with it)

Hi, Hans de Wit, I think there is something wrong with your form. To upload file, the form should specify "enctype" attr to "multipart/form-data". Like this: <form action="addFile" method="post" enctype="multipart/form-data">...

LocalFS manage_overwrite Permissions Question
by Gary Perez 15 Mar '01

15 Mar '01

Hi, all. Using LocalFS 0.9.6 on Zope 2.2.2/Python 1.5.2 under Linux 2.4.1 Here's the scenario... Set up a folder "UserAccess", set up user defined role "rmsuser". Inside UserAccess, set up a LocalFS object "LFS" w/ proper base path. Inside UserAccess, added "acl_users" folder, added user "RMS_User", assigned role "rmsuser". Folder "UserAccess" permissions set to: Acquire = none Anonymous = none Manager = all Owner = none rmsuser = access contents information, delete local files, manage local files, overwrite local files, upload local files, view LocalFS Object permissions set to: same as above. There's an "index_html" DTML Method in "UserAccess" which has the upload form, but permissions are set to aquire = all checked, and the <input type="hidden" name="action" value="../index_html"> is included in the FORM. (Funny aside: found out 'action' was supported in the form only AFTER changing LocalFS.py... what a dolt! ;) Here's the problem... 1) When logged into Zope as the user with "Manager" role, I can upload & overwrite, no problem. 2) When logged into Zope as RMS_User with "rmsuser" role (from a totally different machine, so no problems w/ REQUEST[AUTHENTICATED_USER]), I can upload, but not overwrite. 3) Still "rmsuser" role: If I go back and change permissions on "UserAccess" and "LFS" so "rmsuser" role has all checked (identical permissions to "Manager" role), uploads OK, but still no overwrite. 4) Still "rmsuser" role: However, if I go in "UserAccess" and add local role of "rmsuser ==> Manager", upload & overwrite works. This is bad, though, because I don't want "rmsuser" to be able to access the Zope management screens. I've checked just about everywhere for that one little nugget of LocalFS/Zope truth, but it still eludes me. Is there something that I'm overlooking??
