BASE tag on File objects
by Jon Prettyman 29 Mar '00

29 Mar '00

I've got a number of static HTML files on my site that Zope keeps putting BASE tags into. IMHO, it is inadvertantly appending a slash onto the end of the HREF. For example a file called default.htm in the classified directory ends up with a base tag of: <base href="http://www.nationalmortgagenews.com/classified/default.htm/"> I would think this should be: <base href="http://www.nationalmortgagenews.com/classified/default.htm"> So I have modified: OFS.Image.File.index_html to strip the trailing slash by adding: # clean up the base if neccessary if( RESPONSE.base[-1:] == '/' ): RESPONSE.base = RESPONSE.base[:-1] What think you? -Jon

dtml-in size error
by mauricio_sl＠uol.com.br 29 Mar '00

29 Mar '00

This one goes especialy to ho write zope. I have found that the dtml-in has a problem when you specify a batch-size that is less than the double of the length of the input list. Ex.: a list of 6 itens: when size is 3, dtml-in returns 3 itens, correct. (3*2 <= 6) = true when size is 4, dtml-in returns 6 itens, error. (4*2 <= 6) = false Is this a bug?

I do something very similar in the ZGotW product's root factory:: <dtml-in "defaults.objectIds( 'DTML Method' )"> <dtml-let si=sequence-item> <dtml-with newRoot> <dtml-call "manage_addDTMLMethod( si, '', defaults[ si ] )"> </dtml-with> </dtml-let> </dtml-in> The key here may be the inner '<dtml-with newRoot>', which is forcing the newly-created root folder to the top of the namespace stack, so that 'manage_addDTMLMethod()' is being invoked on it, rather than on the sequence-item. Hope this helps! Tres. -- ========================================================= Tres Seaver tseaver(a)digicool.com tseaver(a)palladion.com

It works, but my sugestion of using _.chr(34) also works. I was looking at the wrong results when testing _.chr().

dtml syntax error with quotes
by julio dinis 28 Mar '00

28 Mar '00

Hi all, This code results in a error: <dtml-let MyVar="_.string.replace(Mytext,'"','"')"> I know its because of the quote in '"' because that cause in same way an error when the "dtml parser" is parsing the code. I've tryed to use '\"' and even _.chr(34) instead of " but the former gives me the same error and the latter dont give a error but also dont do the string replace I want to do. Any help? Thanx, Julio ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

ZClass Icon broken when ZClass moved.
by chas 28 Mar '00

28 Mar '00

I had a ZClass (InnerClass) which was defined within another ZClass (OuterClass) as follows : /Control_Panel/Products/MyProduct/OuterClass/InnerClass And a great many instances were defined with both the OuterClass and the InnerClass. However, in order to catalog the InnerClass (it is not CatalogAware and I do not want it to be), I need to move it to /Control_Panel/Products/MyProduct/InnerClass in order for 'InnerClass' to appear in the select list ('Find objects of type') under the 'Find items to ZCatalog' tab of the ZCatalog. So far, so good. I moved the class and now can catalog it. However, now the icon is broken on all of the instances of the 'InnerClass' ZClass. I have tried adding a new icon under the 'basic' tab of the ZClass definition, but that doesn't help either. I know it's just a petty icon and it doesn't affect functionality but I'd really like to clean this up so any clues/help appreciated. Thank you very much, chas

Version 2.1.6: Change in namespace handling
by Helmut Toplitzer 28 Mar '00

28 Mar '00

Hi! First of all I've to say that I'm a realy beginner in Zope. I recently updated from 2.1.3 to 2.1.6 and noticed following problems: In 2.1.3 <dtml-with "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)"> <dtml-in "getSubjectInfo(fach=REQUEST['fach'])"> <dtml-call "propertysheets.Basic.manage_changeProperties(title=fachbez, empf_sem=empf_sem,diplompruefungsfach=diplfach)"> </dtml-in> </dtml-with> works great In 2.1.6 it produces an Error message that title, empf_sem, diplompruefungsfach is not known by the system (I already Posted that) Now I found out that <dtml-call "SAClass.createInObjectManager(REQUEST['fach'], REQUEST)"> <dtml-in "getSubjectInfo(fach=REQUEST['fach'])"> <dtml-call "_.getitem(REQUEST['fach'],1).propertysheets.Basic.manage_changeProperties(title=fachbez, empf_sem=empf_sem,diplompruefungsfach=diplfach)"> </dtml-in> works fine in 2.1.6. (getSubjectInfo is a SQL Method) Has someone a hint for me? Helmut.

RE: ZCatalog Indexing
by Jason Spisak 28 Mar '00

28 Mar '00

Tobias, The Catalgo uses a stripper to make the indexes smaller. It doesn't index =-+*&)(^%$#@. etc... or numbers. Some words too like 'Bill'. From what I've been told there is a version of the Catalog on it's way which will allow you to put keywords or charaters in a special place that will include them. I couldn't wait for that, and I love Zope, so I came up with a major kludge. catalog_quote() and catalog_unquote(). They are from an External Method which I wrote catalog_quote.py. Here it is: from string import strip, split, join, uppercase, lowercase, find bad_characters=(('.'), ('+'), ('-'), (';'), (':'), ('&'), ('*'), ('%'), ('#'), ('@'), ('$'), ('0'), ('1'), ('2'), ('3'), ('4'), ('5'), ('6'), ('7'), ('8'), ('9')) def catalog_quote(self, ascii): text = str(ascii) for re in bad_characters: if find(text, re) >= 0: text=join(split(text,re),ordinalize(re)) return text def ordinalize(letter): number = ord(letter) number_string = str(number) myletters = lowercase[-5:] + uppercase[-10:] converted = '' for character in number_string: converted = converted + myletters[int(character)] return converted + 'g' def catalog_unquote(self, ascii): text = str(ascii) for un in bad_characters: if find(text, ordinalize(un)) >= 0: text=join(split(text,ordinalize(un)),un) return text I just use it to turn anything that might contain the charaters in bad_charaters into catalogable stuff. Then when you search, you must catalog_quote() your search strings, and you'll get 100% accurate results. Hope this helps. All my best, -- Jason Spisak 444(a)hiretechs.com
