It is a bug ? 404 error onfly

Hi ! My contributor have a problem. His problem is very interesting, but it is in php. I try to help, but I get same problem in Zope. The problem is that: He have a site, and he is paranoid. He is not use static pages to avoid penetrations. So: in a dynamic page he is check the request. If parameters are wrong, he is want to set the resp. header status to 404. (This is a file downloader method, and if the file is invalid, he want to answer 404 - page not found.) He is not want to set location to a static 404 error page (because he is want to "protect" the orig. URL). When he is send header with php to Mozilla, or Opera, these browsers are showing blank page. IE is showing good page (404). Then I try to write this example in Zope, to help it: # test2.py # request = container.REQUEST resp=RESPONSE = request.RESPONSE resp.setStatus(404) When I try this, I get same result in Zope (/test2). So: what is the problem ? And what is the solution ? Thanx for help: ft

Can ZPT form call a url?
by James O'Keefe 25 May '05

25 May '05

On our website we have a form where by a person can subscribe to our announcements list. It is the standard mailman form. We would like to expand on that form such that a user can enter their email address and zip code which we would log to our database and then call the url to subscribe the person in the mailman list. Is there a way to do this? Thanks! Jamie

More tolerant Stripogram (solution)
by Jaroslav Lukesh 25 May '05

25 May '05

Hi all, I was extend SquishDot with wysiwyg editor (origin: vsbabu ieeditor). But it was not accept many tags due too small number of allowed html attributes in stripogram. I was patch stripogram to be more tolerant for eg., tables and other tags (missings: 'html' and 'body'). Make changes to following variables in html2safehtml.py, __init__.py and select your acceptable tags and make changes your code from where you are calling html stripping (for example in SquishDot 1.5 it is SquishSite.py, line 408). can_close = ['ul','li','p','dd','dl','dt','ol','option','bdo','listing','map','optgroup','option','param', 'marquee','menu','multicol','nobr','noembed','noframes','nolayer','noscript','plaintext','pre','q','rt','ruby','s','samp', 'b','i','u','big','small','em','strong','blink','blockquote','center','cite','code','tt','ins','kbd','keygen', 'table','del','strike-thru','dfn','fieldset','font','form','frame','frameset','label''caption','legend', 'h1','h2','h3','h4','h5','h6','head','iframe','ilayer','layer','object','select','strike','sub','sup', 'trow','thead','tbody','textarea','tr','tt','var','xml','xmp','title', 'div','span','a','abbr','acronym','area','th','td'] never_close = ['br','wbr','hr', 'input', 'isindex','base','meta','basefont','bgsound','button','spacer', 'col','colgroup','embed','isindex','link', 'img'] If you want to save space ant you put 'td', 'th','tr', 'p' etc to never_close (which is acceptable for browsers), stripping will destroy html code :-( I dont know if some tag is missing (so sorry), it was done with "visibone web designer's html card" on the desk, not w3c.

display object without index_html
by Christopher Rivard 25 May '05

25 May '05

i am developing a Zope product (2.7) with a "homepage" content type and want this object to display as the index of a folder. for other custom objects, i have display methods that call an index view ( using DTMLFile) of the object like this: #homepage view index_html = DTMLFile('dtml/indexHomepage', globals()) i want this object to display as the index of the folder without: folder/index_html/index_html however, when i render the object, i get: <Homepage at index_html> remove display: http://localhost:8080/www/index_html/index_html has an empty or missing docstring. Objects must have a docstring to be published. how can i ensure that an "homepage" object with an id of index_html will display as the index of a folder (without calling folder/index_html/index_html)? i hope i explained this coherently... any insight would be greatly appreciated- Thanks, Chris

a quick google on mod_zope yeilded http://codespeak.net/z3/modzope/ and some other very old stuff. Anyone know the status of this project? It is a new page... I'm interested in how Zope Corp views this project and what Zope corp may have in the future regarding apache style pluggins. -- David Bear phone: 480-965-8257 fax: 480-965-9189 College of Public Programs/ASU Wilson Hall 232 Tempe, AZ 85287-0803 "Beware the IP portfolio, everyone will be suspect of trespassing"

Re: [Zope] newbie question
by Barry Drake 25 May '05

Thank you Phillip. I modified the zope.conf file as you suggested and did sudo ./zope stop ... usual msg sudo ./zope start ... usual msg Then generated the error. The error log shows the same output as before. Not only should the line number be one higher, I also put a dummy variable name on that line to generate a stupid error msg. How can it not be getting to that code? I've searched for another Zope instance, but found none. Also, you are saying that I probably will never get the Control Panel back on this site with Product Management tools; no Product refresh then, I suppose. I'll have to thank the previous developer, as you suggest! (of course there is no documentation either, arrgh!) If you can think of anything else, I'd appreciated it. Thanks.

Thanks for your help. I really needed another brain to bounce things off of so I can get out of the rut I'm in. You've given me some fresh ideas to try. Thanks.

surprising interaction between Javascript and Zope
by Dennis Allison 24 May '05

24 May '05

We have a need to set a session variable concurrently with a user submitting a form on a mouse click. I accomplish this with a bit of JavaScript associated with the OnClick attribute of the form: location.replace('/setSesVar?var=nams&val=xxx;frm.submit(); which does the job except that the setSesVar script is executed twice, a fact we discovered by monitoring calls to the setSesVar script. Once with an incorrect parameter, and secondly with a correct parameter. There is probably some obvious explanation, but I am stumped. Setting invalid values into session variables, even transient invalid values, can cause problems.

Managing Users with Postgresql.
by Fernando Lujan 24 May '05

24 May '05

Hi, First let me describe my environment. I have a Postgresql database that stores all users, and booleans which describe permissions. The users log on in my application using a WebForm, I run a ZSQL Method and set all permissions in the Session. I manage the security using Session calls, checking each permission and then allow or deny access to the object. I know that it isn't the best solution, and now I want to change it! :) Which is the best solution to solve my problem? I found pgUserFolder. But I'm not so sure if this will be the best solution. Thanks... Fernando Lujan

strftime
by Luiz Fernando B. Ribeiro 24 May '05

24 May '05

Hello, I'm displaying dates retrieved from a MySQL database using: <span tal:content="python: news['Date'].strftime('%d/%m/%Y')">Date</span> In a strange behaviour using strftime is displaying dates with 1 day past, example 10/05/2005 is being show as 09/05/2005. If i change the code to show the date as it comes from MySQL it is correct and if I change the code to not use strftime and manually retrieve .month() .day() .year() it is also correct. My locale in Zope is set to BRT and in console everything works. Zope 2.7 and Pthin 2.3 from debian sarge. Thanks, -- Luiz Fernando B. Ribeiro Engenho Soluções para a Internet +55 11 6959-7610
