'selection' types question
by Brown, Brian 23 Sep '99

23 Sep '99

I was trying to figure out how to use the types 'selection' and 'multiple selection' and found the following: In <zope dir>/lib/python/ZClasses/Property.py, the following code shows that these type should result in an HTML Select box, if t=='selection': return ('''  <select name="%(id)s">  <option  SELECTED ></option>  </select>  No value for %(id)s ''' % p ) return '' ...but I couldn't figure out how to get any data in it. Then I found in <zope dir>/lib/python/OFS/PropertySheets.py: if type in ('selection', 'multiple selection'): if not value: raise 'Bad Request', ( 'The value given for a new selection property ' 'must be a variable name<p>') prop['select_variable']=value if type=='selection': value=None else: value=[] setattr(self, id, value) This told me that I should be putting a variable name for the value, and that worked fine. The problem them comes with 'multiple select' boxes. Nothing displays, and I think that is due to there being no analog for the first code snippet above. Can someone with more Zope Zen than I confirm this? I think it's a bug, and if so I'll put it in the Collector. btw, this is released Zope 2.0.0 on linux, source release. Thanks! Brian

Newbie _still_ unable MySQL connection string on NT
by David Robson 23 Sep '99

23 Sep '99

Jens Vagelpohl and Tony McDonald kindly contributed the correct answer to my connection string question. Tony summarized it as� >> MySQL@SERV3 UserName UserPW > this should work if the database you > want to use is called MySQL Apparently I have a deeper problem. At the very least I�m foundering in terminology. Is this matrix correct re database terms? Item Correct term Commonly-used term Database application MySQL database Data file MyFileName database Table MyTableName table So�I should use a connection string like the following, right? MyFileName@SERV3 UserName UserPW But, working remotely, I haven�t created a database file so MyFileName doesn�t exist and, of course Z SQL Method won�t permit creating a database file or table without a connection. I�m missing something basic here. I tried connecting to an existing sample MySQL file function.tst with no luck. Also: Should the path be represented in the db filename�as: C:\mysql\examples\tests\function.tst@SERV3 UserName UserPW MySQL is running as an NT Service. Must I additionally activate a MySQL Server on port 3306?

You can do a whole lot without using Python. For someone who knows how to use a programming language, picking up python is probably not going to be too difficult. >> 2.

If you can do CGI >on your ISP, you can do PCGI with Zope. [some snippage above] One caveat: I have found that many hosting companies are not keen on the PCGI way of doing things, because it permanently sucks up memory, etc. In looking at hosting companies, I found that to be a bigger issue than running Python. (I thought most hosting companies provided Python already). Still, I think Zope is powerful enough to easily justify a switch in hosting companies (which is not really *that* big a deal for many configurations). In fact, I *did* switch hosting companies so that I could use Zope. Kevin

>From my experience of trying to intrest co-workers in Zope there were 2 problems. 1. Python - they don't know python, but might be willing to learn if it wasn't for 2... 2. ISP/Web Hosting companies don't sopport Pyhton as a cgi enviroment or Zope. Very few, from my experience, want to switch ISP/Web Hosting for something they have not tried in a new language. Don't take these comments to mean that I don't like Zope I love it but can't justify going with an untrusted ISP/Web Host. I don't know the solution to this one. Any help would be appreciated. Maybe what effect adding Zope, along with Apache, would have for the ISP/Web Host. Technicaly do they have anything to worry about or is they general lack of python experience the only factor. Any ideas??? ===== ------------------------------------ Brian M Lauer <mailto:fozbaca@yahoo.com> <http://w3.one.net/~fozbaca/> <ftp://ftp.one.net/pub/users/fozbaca/> __________________________________________________ Do You Yahoo!?

ZCatalog vs. external database ...
by Darran Edmundson 23 Sep '99

23 Sep '99

We need to add an academic publications database to our budding Zope site. A couple of newbie questions: 1) Is creating a "Publication" ZClass and then using ZCatalog a viable option? or 2) Is the GadFly Product okay for a smallish 1000-2000 record database? The Add page makes a comment about Gadfly operations being done in memory - does this mean that the database is not persisent in the Zope DB? Cheers, Darran. -- Darran Edmundson [Darran.Edmundson(a)anu.edu.au]

Mailman web pages unreachable
by Ken Manheimer 23 Sep '99

23 Sep '99

Due to some growing pains we're having to shift things around on zope.org. One temporary victim are the mailman community mailing-list web interface pages - they're currently unaccessible. We hope to have them back back later today, but in the meanwhile you'll have to wait to adjust your subscriptions - or you could try the email service, eg for the zope list, send a message to zope-request(a)zope.org with the word "help" (sans quotes) as the subject. Sorry about the disruption! Ken Manheimer klm(a)digicool.com

In your costructor DTML Method, after manage_changeProperties, do: <dtml-call index_object> This is needed because there is no way for the XClass to detect wether or not you are making changes to the object after you added it to the ODB. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | T: +31 35 7502100 F: +31 35 7502111 | mj(a)antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ---------------------------------------------
