The proper usage of Sequence-item
by jesse 18 Jul '00

18 Jul '00

I'm improving on Smarter forms so that instead of having to hard code every field into the code that checks for errors, it automaticly reads the dictionary that is in REQUEST and checks every key in it. I'm trying to work with this... <dtml-call "REQUEST.set('finished','true')"> <dtml-in "REQUEST.keys()"> <dtml-comment> starting the loop </dtml-comment> <dtml-if "_[sequence-key].value('')"> <dtml-comment> I'm saying that if the current key is empty, display this. </dtml-comment> <li>Please fill in your <dtml-var "_['sequence-key']"> below <dtml-call "REQUEST.set('finished','false')"> </dtml-if> </dtml-in> <dtml-if "REQUEST.get('finished')=='true'"> You're done! Thanks for your input <dtml-var fname>. You could put a link to somewhere else on your site here... <dtml-else> Please correct this and click the Next button to complete the form. <dtml-var expr="mainform_include()"> </dtml-if> any input would be helpful.

I'm close to > getting them properly interfaced with DTML namespaces, so that DTML can > invoke Python Methods using simpler DTML syntax. I've followed this thread with particular interest. I'm almost 18 months old with Zope and have done many useful things with it. But my journey up the learning cliff has been punctuated by spells of doing other things (I'm not a programmer in real life) during which I inevitably forget most of what I've just learned about DTML (and slip back down the cliff). OK, this is true of most things (computer languages, foreign languages, mental arithmetic, parenthood, etc) - if you don't use it, you lose it. But there is something about DTML that distinguishes it (for me) from other languages - it's the rate at which it decays on you. Python's decay constant is much more favourable. So I've learned a rule of thumb - if I'm writing DTML and it isn't flowing then I really ought to be using Python. PythonMethods are nice but, as they stand, you only have access to built-in functions. So if you want to import modules you have to resort to External Methods. [Am I talking nonsense here? My empirical experience is that I can use string functions in a PythonMethod but not, say, stuff from the time module. Neither string nor time are built-in though ..... so why one and not the other?] The point of these reflections: * PythonMethods ought to be a high priority IMHO. * DTML is holding Zope back for the rest of us (and is arguably a "proprietary" component of Zope (in that you can't use it anywhere else) - this is a disincentive to many power-Perl,JSP,<name-your-scripting-poison> users I suspect. * Please can we import Python modules from PythonMethods (or can we already and I don't about it, or does this break the sandbox that PythonMethods is meant to provide)? * Don't worry about changing DTML syntax. It's an excellent marketing ploy to ensure good sales of the 2nd edition of The Zope Book ;-) Apologies for any misconceptions in any or all of the above.

I need to obtain the current exchange rates for the yen, mark, etc. with at least once a day, preferrably every other 15". Is there an easy way to do this in Zope? Adrian

Products and 2.2 Final
by Rogerio Atem de Carvalho 18 Jul '00

18 Jul '00

Just a simple question: I am using 2.1.6 with LocalFS, CachePool, SQL Input Wizard, MetaPublisher and others... I am thinking now in upgrading to 2.2 final. Is there any product that is not compatible with 2.2 final? regards, Rogerio Atem ------------------------------------------- E-mail enviado pelo servidor do CEFETCampos

I am trying to compare which_table to the exact string Plays. Plays is not a variable/argument/integer/..../whatever, I am just trying to see if the string that is returned from one of the fields of my form (which_table) is equal to the string Plays. <snip> Tim: tim.hicks(a)iname.com

I tried to write and explanation, but figured after a while that I didnt really understand the exact reason why not. I have rendered dtml in python by writing a class that is derived from DTMLDoc (similar to the Wiki style).

Re: [Zope] Creating Factory Objects (Products)

Haha, thanks for the 'wisdom' cookies:) Here are the last two lines of the traceback: File /usr/local/Zope-2.1.6/lib/python/OFS/Application.py, line 249, in __bobo_traverse__ (Object: ApplicationDefaultPermissions) File /usr/local/Zope-2.1.6/lib/python/ZPublisher/HTTPResponse.py, line 511, in notFoundError NotFound: (see above) Maybe because i'm a newbie, i tend to feel that Zope's error messages(or traceback) are not as clear as (for e.g.) PHP's error messages. Perhaps you can give me some pointers here? regards, firestar ------Original Message------ From: Dieter Maurer <dieter(a)handshake.de> To: Firestar <theebh(a)mail.com> Sent: July 17, 2000 11:23:04 PM GMT Subject: Re: [Zope] Creating Factory Objects (Products) Firestar writes: > "Resource not found > > Sorry, the requested Zope resource does not exist. > Check the URL and try again." followed by the tracebacks... You first need to determine what resource is not found. The tracebacks may help you with this. After you know the resource, you will ask, "why". If you are lucky, this becomes obvious, once you know "what". Dieter ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup

Newbie: How to create a Oracle connection (DCOracle)
by gustavo 18 Jul '00

18 Jul '00

Hi List, Finally, I installed DCOracle and works fine. But, how to create a Oracle connection inside Zope? I tried to add a SQL Method and received this warning: Warning: There are no SQL database connections. You need to add a Zope SQL database connection before you can use a Zope SQL Method. I not found nothing about that in documentation. Could you help me? Gustavo

<dtml-if> errors in sql method
by Tim Hicks 18 Jul '00

18 Jul '00

<dtml-if "which_table == 'Plays'"> SELECT * FROM <dtml-var which_table> WHERE "Play title" like <dtml-sqlvar "'%'+_.string.strip(form_string)+'%'" type=string>; Can anybody explain to me what is going on with my zsql method? Zope gives me the following error when I try and change my method to what is above. Invalid attribute name, "which_table", for tag <dtml-if "which_table == 'Plays'">, on line 16 of <string> I've scoured the mailing list, but I'm still mightily confused. which_table is one of the arguments for the the sql method and Plays is a string that I want to compare it with. which_table comes from a form elsewhere. I'm sure it's something really simple, and I'm sure it's been discussed here before (at length?), but ATM, I don't even know what I'm looking for! Thanks for the help tim
