Howto engineer a scientific paper system

How to engineer a scientific paper system Are there products out for this, should we produce one? ------ In short, I would like to have Zope assist me in producing a scientific paper. So how can I produce pointers from within the text to objects holding more information about these pointers, i.e. a referene within a paragraph is linked to the bibliography. ------ My setup so far is a folder structure, with DTML Documents for content that have Properties holding the references in token (semi-colon) separeted lines. Methods are used to parse the folder (having chapter properties) and DTML Documents in order to get a table of content structure and html-styled reference list respectively. ------ The method I wrote are much of the type of dtml_tree using dtml-in to identify the object, produce something with that object, and then calling the method again from within the method. Sometimes, though, I get an infinite recursion. This requires lots of debugging, as the loads of methods intermingled with standard puplishing methods are hard to overlook. The parsing techniques would need exception handling and whenever I split a method up, the value is passed on the the request namespace (that might produce further havoc in a newbie scope of understanding). A class object system instead of scripts should work better and should also be easier to enrich with additional qualities later in the development process (as it still is the paper first that should get done instead of the software system). So maybe it is time for a full revision, letting classes produce the work. Are there other ways to achieve this? Maybe should I a produce something such as a lightened ZWiki product for that purpose. Or, should all content go into SQL tables? What steps should I take next? Any further ideas of co-problem-solvers? Regards, Christian

Copy/Paste problem
by Oleg Broytmann 03 Jul '00

03 Jul '00

Hi! (Nobody dared to answer, trying to do some research...) I (and some my friends) have problem with Copy/Paste. Sometimes it's wotking, but often Paste button does not appeared after Copy/Cut. I put debug DTML method on a site - just <dtml-var REQUEST> and found browse always pass __cp cookie, so it is not a cookie problem. I copied the cookie value and tried to _cb_decode it myself: from marshal import loads, dumps from urllib import quote, unquote from zlib import compress, decompress def _cb_decode(s): print unquote(s) return loads(decompress(unquote(s))) print _cb_decode('x%DA%D3%60b%60%60%C8%04b%86hF%20%A1%01%E2%16%83%B9%CC%20%16%07%03%1C0%21q%D8%95%919%B3%20%92%9D%04%29') error: MemoryError: Out of memory while decompressing data. I did experimets with by copying just one DTML document in a folder 1 level below the root, so this is not a problem with too many object or too long path. What is it? Sun Sparc, Solaris 2.5.1, python 1.5.2 compiled by me from sources, Zope (both 2.1.4 and 2.2.0b3) compiled from sources; gcc 2.7.2.3. I did some experiments on Linux. Paste works a little better there, but not much - often Paste button does not appeare. Oleg.

zope and caching
by Bak ＠ kedai 03 Jul '00

03 Jul '00

hi good people i've been using zope for quite some time now. everything has been great; zope, the mailinglist, products are great! <rant> i want to serve a dynamic site and zope fits the bill. now, i think i want to have some of the dynamic methods cached, so as to reduce the cpu cycles on my server. y'see, the site has slowly bogged down as the number of users increase(dwhich is good, the users increase :)) and cpu cycles processing user requests have increased. i'm not too sure (being a newbie) whether all my methods contribute to the consumption of cpu cycles. caching. yes, i've tried putting cache headers on my docs, but it seems that ie do not honor the headers, or maybe i put it wrongly. ie(4.x and 5.x) kept showing the cached version of my pages, even after clearing the local cache. only deleting the temp files solved the problem. i had no bad behaviour from netscape. also tried ZCache, but according to the product author, better wait for the next version. so, i'm waiting. meanwhile, i've tried Cache Pool, and it looks good. i have yet to test the effectiveness of Cache Pool, but it looks as if the page loads faster now. </rant> the point is this: will zope ever have a method cacheing modules/object in the future? for i think zope can be faster if he/she/it have this built in. just a thought. what say you guys? how do you guys tackle this? thanks -- ------------------------------------------------------ http://www.kedai.com.my/kk Am I Evil?

Re: [Zope] calling standard_html_header from external methods

What arguments should I pass to it? The __call__ function of DTML methods gets the following arguments: client=None, mapping=None, **kw. You therefore may call it: "self.standard_html_header(self,REQUEST)" or "self.standard_html_header(None,REQUEST)". Dieter

zope not authorizing
by Rajil Saraswat 02 Jul '00

02 Jul '00

i installed the zope-pcgi rpm file. the default user is superuser and password is 123. but when i give these values in the prompt, the software does not authorize me. i also changed the access file in /var/zope using zpasswd but still the login is not working. earlier i was using zserver and it was working fine, is there some problem with pcgi, is there some changes to be made. i did all the changes as given on the rpm page at zope.org(httpd file change) however when i goto http://localhost/static the zope screen is not displayed. but if i goto http://localhost/cgi-bin/Zope.cgi then the welcome screen comes. but i am not able to authorize myself at the auth. prompt. using pcgi what is the default object url, will it be http://localhost/Zope.cgi/sample. if this is the case can we change it to http://localhost/sample. basically i want the zope root to be located on http://localhost instead of obscure url like http://localhost:8080 or http://localhost/cgi-bin/Zope.cgi. This was the reason i wanted to try out pcgi. can we do this. please help!!

"lambda" is not a function but a keyword in Python expressions. It, therefore, is not required in "_" to be used. Dieter

You can do anything programmatically, that you can do manually through the management screen. Just look at the DTML code that generates the respective form. In your case (adding a role), the DTML source is "AccessControl/access.dtml". The analysis of the code shows you, that the method "manage_defined_roles" does what you want. It gets 2 keyword parameters: "role=your_role" and "submit='Add Role'". Dieter

I do not like "mailman" at all. At least as used by the Zope lists, its digest mode is utterly broken. Dieter
