Hi All I just need a little help, (Zope Newbie:) ) I want to create a website creator, I want to provide my end users with a 1-2 page form with lots of check boxes, list boxes, etc.. Once the users has finished making his/hers selections, I want my product to go and create the web site. easy :) Now for the questions, How do I call other products from mine? ie, say I have install the Znavigator product. On my create website form the users has chosen a default menu of 'home','products','services','contacts'. >From my product I want to be able to call the Znavigator , create the menu, than create the menu items. I can us manage_addFolder to create folders, but I can not figure out how to call add on products? Is there documentation on all the manage_xxxx functions? Can anyone point me in the right direction, Please ---------------------------------- E-Mail: Stephen Cimarelli <stephen(a)clari.net.au> Date: 14-Aug-00 Time: 09:20:12 ClariNet Internet Solutions +61 3 9486 0811 www.clari.net.au ----------------------------------

Ivalid Integer from Zope
by Herring, William O. 13 Aug '00

I am using the Znolk Input Wizzard with postgresql tables. One of the variables in the table is an integer and can have null values. However, in the update and insert forms, if I attempt to leave the value null, I get the following error from Zope: "Invalid integer value for weight.bcs" The variable is defined throughout as :<dtml-var bcs null=""> Any help would be appreciated.

JavaScript help!
by Peter Be 13 Aug '00

Maybe not a Zope specific question but the problem arises only with Zope DTML. The documentEdit.dtml page in OFS has this little HTML: <TEXTAREA NAME="data:text" WRAP="Off" COLS="50" ROWS="20"></TEXTAREA> And what I want to do is trigger a JavaScript that replaces specific characters in the textarea box to others. I.e. Replace swedish ö with HTML: ö The problem is the name of the textarea box! It is called "name:text" If I replace the name of the textarea box to say "data", then my JavaScript works fine. I have tried to "eval" the box, but to no effect. Any ideas?? ---------- Here's the JavaScript source: <script language="JavaScript1.2">  </script> ----------- Here's the JavaScript error: invalid label. document.manage_edit_form.data:text ..................................................^

The site I am building will have many Zope dynamic componants, but also a good share of wrapped static HTML pages maintained by content contributors in Frontpage/Dreamweaver. I know that orphaned files and broken links *will* become a problem over time. There was a discussion of this issue recently in this list. Look into the list's archive for valuable hints. Dieter

RE: [Zope] application/octet-stream vs. application/msword
by Jean Jordaan 13 Aug '00

Hi Dieter & all > > How does Zope recognize the type of a file? > It uses "OFS.content_types.guess_content_type" OK, so 'manage_addFile' uses 'guess_content_type'? I'm a bit confused here .. I see three lists of content types, excerpted below. They are in: 1. 'lib/python/OFS/content_types.py' 2. 'bin/lib/mimetypes.py' and 3. 'ZServer/medusa/mime_type_tabel.py' There is some overlap between the lists (eg. '.doc' occurs in 1 and in 3, and '.cdf' occurs in all three). What relation is there between the lists? The other thing I'm wondering is, it looks as if '.doc' should *always* be recognized as msword. How could it sometimes turn up as octet-stream? To add documents I call: <a href="manage_addProduct/ccDoc/ccDocClass_factory"> Add a document.</a> The initial method of 'ccDocClass_factory' is 'ccDocClass_addForm', and that form's action is 'ccDocClass_add' which eventually calls: <dtml-call "manage_addFile('', file, '')"> So how come '.doc's get added as application/octet-stream ? Excerpts: --------- In 'lib/python/OFS/content_types.py' I find: ........................................................ # This gives us a hook to add content types that # aren't currently listed in the mimetypes module. _addtypes=( ('.cdf', 'application-x-cdf'), ('.doc', 'application/msword'), [...] ('.xul', 'text/xul'), ) ........................................................ and in 'bin/lib/mimetypes.py' I find: ........................................................ types_map = { [...] '.bcpio': 'application/x-bcpio', '.bin': 'application/octet-stream', '.cdf': 'application/x-netcdf', '.cpio': 'application/x-cpio', '.csh': 'application/x-csh', [...] '.zip': 'application/zip', } ........................................................ and, finally, in 'ZServer/medusa/mime_type_tabel.py' I find: ........................................................ # Converted by ./convert_mime_type_table.py from: # /usr/src2/apache_1.2b6/conf/mime.types # content_type_map = \ { [...] 'cdf': 'application/x-netcdf', [...] 'doc': 'application/msword', [...] 'zip': 'application/zip', } ........................................................ -- jean

Slightly OT: Server Admin w/Zope - best approach?
by Nigel Head 13 Aug '00

13 Aug '00

Slightly off topic perhaps but potentially intersting to many here, I hope! I'm considering, partly out of curiosity and partly out of hopes that I may get some customers one day who could use it, how I would go about implementing a server administration tool (a la Webmin for example) within a Zope infrastructure. It seems to me that a lot of use could be made of the Zope user/role/privilege facilities to provide a fine grained delegation capability in a relatively secure way; the benefits are obvious (at least to me). Likewise DTML and the SQL facilities couls allow very easy integration with a customer tracking/billing database and products would let me plug-in new capababilities in a neat way. Sounds nice to me! The question I have still to find a good resolution to is how to deal with the backend functionality - updating files, running scripts etc which probably need, at least in part, to be run as root (or as a member of wheel at least). I can see several possibilities -- build an interface to linuxconf for example (but that's non portable), create a slew of suid scripts executable from zope external methods (but how risky is this?), put zope in 'wheel' (no, I don't think I woudl want to do that) and so on ..... I suspect someone may have done something similar already or at least have an opinion on the best way forwards ... any suggestions would be welcome. Of course I suppose I could actually use webmin but that would mean the other P language which I have forgotten ho-to for the moment). -- Nigel Head Houbits Hi-Tech Servers nhead(a)houbits.com
