ZPublisher.Client misleading exceptions
by R.Taylor＠eris.dera.gov.uk 22 Dec '99

22 Dec '99

We are using ZPublisher.Client to call a "manage_add...." function to create a ZClass instance. We are seeing some strange exceptions. The "manage_add" function works through the web management interface but when called from ZPublisher.Client it creates the instance and then generates an exception. In the following code place, uname, pwd are strings and kw is a dictionary. place is 'http://zopehost/folder/manage_addProduct/Comment/manage_addComment' def go(place,uname,pwd,kw): import Client return(apply(Client.Function(place,username=uname, password=pwd), (), kw)) The desired object is created, however an exception is also generated. Traceback (innermost last): File "<stdin>", line 1, in ? File "autoadd.py", line 14, in addComment go(place,uname,pwd,kw) File "autoadd.py", line 6, in go return(apply(Client.Function(place,username=uname, password=pwd), (), kw)) File "/usr/local/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Client.py", line 225, in __call__ self.handleError(query, ec, em, headers, response) File "/usr/local/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Client.py", line 240, in handleError raise t, RemoteException(t,v,f,l,self.url,query,ec,em,response) bci.ServerError: 302 (File: Unknown Line: Unknown) 302 Moved Temporarily for http://aedmondson:8080/Ed/manage_addProduct/Comment/manage_addComment Whereas creating this object through the ZOPE management interface no error occurs, and we get redirected to the correct management page. Can anyone explain this exception and why it is being generated. On a related note: When trying to create an object with a already-used id (using the code above) through the ZPublisher.Client we get the following exception. Traceback (innermost last): File "<stdin>", line 1, in ? File "autoadd.py", line 14, in addComment go(place,uname,pwd,kw) File "autoadd.py", line 6, in go return(apply(Client.Function(place,username=uname, password=pwd), (), kw)) File "/usr/local/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Client.py", line 225, in __call__ self.handleError(query, ec, em, headers, response) File "/usr/local/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Client.py", line 240, in handleError raise t, RemoteException(t,v,f,l,self.url,query,ec,em,response) bci.NotFound: <HTML><HEAD><TITLE>Ed's discussions test</TITLE></HEAD><BODY BGCOLOR="#FFFFFF"> <TABLE BORDER="0" WIDTH="100%"> <TR VALIGN="TOP"> <TD WIDTH="10%" ALIGN="CENTER"> <IMG SRC="http://aedmondson/p_/ZButton" ALT="Zope"> </TD> <TD WIDTH="90%"> <H2>Zope Err (File: /usr/local/Zope-2.0.1-linux2-x86/lib/python/OFS/ObjectManager.py Line: 209) 400 Bad Request for http://aedmondson:8080/Ed/manage_addProduct/Comment/manage_addComment Whereas through the ZOPE management interface attempting to create an instance with same id produced this: <H2>Zope Error</H2> <P>Zope has encountered an error while publishing this resource. </P> <P> <STRONG>Error Type: Bad Request</STRONG><BR> <STRONG>Error Value: The id 1 is invalid - it is already in use.</STRONG><BR> </P> We fully except to get the error but the error from the web management interface is much more informative. How do we access this useful diagnostics from ZPublisher.Client. Thanks for your help. Thanks, Richard Ed

with-tag-problem ..
by Geir B Hansen 22 Dec '99

22 Dec '99

Hiyah zopistas. I am estranged to why i cannot solve this problem by myself. I thought I had finally come to peace with namespaces and objects, but, alas, no.. I have a method which makes a folder and creates users with local roles for it, based on submissions from a form. The problem is, I want to make another object, let's say another folder, within my newly created folder. <dtml-call "REQUEST.set('id',REQUEST.name)"> <dtml-call "acl_users.manage_users(submit='Add',REQUEST=REQUEST)"> <dtml-call "manage_addFolder(REQUEST.name, REQUEST=REQUEST)"> <---with tag to get within the newly created folder goes here----> <dtml-call "manage_addFolder('testfolderwithin', REQUEST=REQUEST)"> <--end the with tag-----> tried all variations of the with tag i could think of, but without success: <dtml-with name> <dtml-with "name"> <dtml-with _['name']> they all return 'name' as a string, not an object, and the 'testfolderwithin' is created in the parent folder, not as a child of 'name'... i also tried using ..-call "name.manage_addFolder .." with all the above variations. Then i get the expected error that 'name' is a string not an object. How can i make Zope understand that i want to reference the newly created 'name' folder (of which we do not know the actual name) as an object and not a string ?? -- Geir B Hansen web-developer/designer geirh(a)funcom.com http://www.funcom.com

RE: [Zope] Links inside of StructuredText
by Miller, John M. 22 Dec '99

Your structured text is fine. It's the dtml-var statement that's tripping you up. Try <dtml-var stxtest fmt=structured-text> -or- <dtml-var stxtest fmt="structured-text"> Most of the documentation for structured text is either in the How-To (http://www.zope.org/Members/millejoh/structuredText) or in StructuredText.py (which is how I found out about the fmt=structured-text bit).

Hi Zopistas! We are happy to announce the birth of another zope powered site. It's a portuguese digital magazine with daily articles on different themes. Related to those articles are external foruns and websites which soon will be internal stuff when we finish the hacking on ZRTChat and ZDiscussions. It makes big use of zcatalog, kmnetnews and ODP viewer Products. Thanks for all the help we found on this mailing list and we hope you enjoy it.

Skins - a few questions (LONG)
by maxm 22 Dec '99

22 Dec '99

Hi I, like a lot of other people have fallen in love with Zope, and I can see the benefits of it all. Therefore I will start working in this enviroment from now on. One of the things I would really like is the ability to make skins. A way to make different layouts that can be changed at a whim. Very useable for instance when somebody wants to browse a site with the Lynx browser, and somebody else wants to use the Acme 17.6 browser, or you simply want to use the same logic to drive sites with different layouts. A products like squishdot would be a prime candidate for this. The skin could be choosen on a per session base or dependening on what browser is used or saved in a user preference setting or all of the above. I have been working with IIS/ASP and Apache/PHP for a while and have made various skin systems in these enviroments. the general idea is that i make some templates into which I insert the content and then call these templates as functions: --------------------------------------------------------------- PHP examples: function Box($Title, $Content){ return " <table width=100% Border=0 cellpadding=3 spacing=0> <tr bgcolor=darkgreen> <td> <font size=-1 color=white><b>$Title</b></font> </td> </tr> <tr> <td> <font size=-1>$Content</font> </td> </tr> </table> " } function Page($Title, $Content){ return " <html> <head> <title>$Title</title> </head> <body> <h2>$Title</h2> $Content </body> </html> " } All I have to do then when rendering a page in PHP is to write this: <? echo Page('Testexample','You are welcome') ?> I can change alle my layout for the whole site in one place and the pages a wonderfully short with only the page logic being different on each page. I hate when html and logic is mixed on the same page. I have also made sites where the pages are saved as html files that I then load and replace some keywords with the correct html via functions. a simplified example can be seen here in python : --- >!-- Template file shown here here --> <html> <head> <title>Welcome to my site</title> </head> <body> %Content% </body> </html> --- def DK_Page(content): fileinput = open(TemplateFilePath + 'Template.htm' , 'r') FileContent = fileinput.read() fileinput.close() return re.sub(r'\%content\%', content, FileContent) --------------------------------------------------------------- This is the same principle as the PHP example, but with the layout completely seperated. The advantage here is that the page designer can have a whole page to work in, and save it all as an HTML file and only has to remember to put the %title% and %content% and other tags in the templates. This is muche healthier for a designer I have found (I work at an advertising agency with a lot of traditional Layouters). Personally i don't like the traditional zope way of doing it with:  content  As you have to split up a layout that really shouldn't be split. It's hard for designers, a bit cumbersome, and it is errorprone allways having to remember to cut a file in two and then uploading both. Furthermore you cannot easily have different users use different skins this way. I would really like for the designers to be able to put up template html files with a few keyword tags in them. ftp to the ZODB is fine, but a folder in the filesystems would also suffice. A directory/file structure something like this: skins Skin1 page.html box.html style.css Skin2 page.html box.html style.css Skin3 page.html box.html style.css Well my real question comes here: -------------------------------- 1) To get started I have made a dtml method called "box" in the root of my zope site that looks like this: <table spacing=3 border=0 padding=0 width=100%> <tr bgcolor=green> <td><font size=+1 color=white><b></b></font></td> <tr> </tr> <td></td> </tr> </table> How do I call it from a dtml document? I have tried different things and I cannot seem to succed. Perhaps I should user an external python method? this would be a lot more like I am used to, but would probably result in bastard dtml. -------------------------------- 2) Is there any other obvious way to do this in Zope? Would it be a waste of time implementing a product like this as it would be easier to ... -------------------------------- 3) Is there anybody who can see an obwious way to turn this functionality into a product and perhaps give me a few hints or an outline. Any ideas are welcome as I havn't yet grokked the zen of Zope. ------------------------------------------------------------------------ Max M Rasmussen, New Media Director http://www.normik.dk Denmark e-mail mailto:maxm@normik.dk
