Re: [Zope-dev] Zope and Python 2.4
However, RedHat have now released Python 2.4 in the Fedora development stream and it will ship with FC4. Does ZC have an official position upon this yet? Speaking as Zope release manager but not as official of ZC: Python 2.3.4 will likely be the recommended Python version for Zope 2.7. I am personally running Zope 2.7.3 with Plone since some weeks under Python 2.4b1 but I am doing this at my own risk. Python 2.4 might be of interest for Zope 2.8. Going for Python 2.4 just because Fedora ships with it is not really an argument. Add to that the fact that it is *not advisable* most of the time to use the Python interpreter that comes with the system. The reasons have been laid out before, like the fact that the interpreter is most likely compiled with strange flags, and that updating a system-level Python with vendor-supplied packages can have bad consequences for your Zope install. The vendor-supplied Python is (probably) tested with vendor-supplied packages that use it, but certainly not with third party software such as Zope is in this case. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] Re: Zope and Python 2.4
However, having to fork off the main Fedora branch in regard to Python dependencies (which directly affect Anaconda, up2date, GTK, and most of the desktop applets) has major implications for how we maintain our distro. As Andreas said, there is no forking involved. You should have a separate Python that's used by Zope only, and not by the other Python-based tools. It's like the old Zope binary releases - they all came with their own Python. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] Re: any limits on object number?
Even using BTreeFolder to store all objects I was getting 300s delay to show a single object (ok, it's an archetypes-based one, containing 50 fields, splitted into 7 schematas, with lots of fancy stuff...). So I made a directory hash structure based on UID from each object (an AT UID is md5, so we have a hex base). My own experience with BTreeFolder2 does not support your diagnosis. I do not believe BTreeFolder2 is the problem here. On a CMF-based CMS that I helped develop the largest BTreeFolder2-based containers held ca. 60,000 items at the top level, meaning we did not use a directory structure to restrict the number of items per folder. There was zero delay retrieving singe items and even stepping into the ZMI where it shows 1000 ids at a time was sub-2 second response time. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] any limits on object number?
When we tried to upload objects from wikipedia's sqldump of after about 40,000 objects in a folder the script went for a toss. roughly each time we ran the script the same problem. even to visit the folder of even 1000 objects through ZMI is a pain. I think that is where BTreeFolder2 will be very useful. Your observations make sense in the context of the standard Zope folder. BTreeFolder2 will help. I am assuming whatever script you use to populate the folder(s) commits the transaction ever N objects, right? I am also thinking to use a squid cache style of storing objects in zodb, where the objects go into many subfolders (i dont know what is this method called technically) with several sub folders with names alphabetized/numbered. this way i can store large number within zodb though not in the same folder/BTreefolder2. Should I use both methods? I would definitely use the subfolder method. Not related to Zope, but what about filesystems? there must be a limit on the number of files within one folder depending on which filesystem one uses. The ZODB, in case you use the standard FileStorage, is one monolithic file. So there is no large number of files on the server file system regardless of how many objects you store. For files on the file systems your choice of file system depends not just on the number of objects but also its size. To re-use your earlier example of Squid cache files, which are numerous and mostly small, ReiserFS is normally recommended. It deals much better with large quantities of files in one folder. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] AW: Caching prob with AHCM and headers
I know, I was just trying to figure out how this was supposed to work. Currently setting Last-Modified seems to be the only way to get something cached in Apache; Expires alone is no good, and adding an Etag header doesn't seem to have any effect either. Maybe this should be classified as an Apache problem? Shouldn't Apache cache pages that have Expires? Please keep in mind that **Apache is not a cache server**, it has caching attached more like an afterthought to the mod_proxy. If you want predictable caching you will need to use real caching software such as Squid.

Memory is cheap. jens On Friday, Aug 22, 2003, at 17:38 US/Eastern, Leonardo Rochael Almeida wrote: Hi, For a long time now, one of our clients, running Zope 2.5.1, has been experiencing memory leaks. For a time this has been relieved by restarting Zope every day at 4am. Lately this was not enough, however, as Zope started taking more and more memory, to the point that it frequently required more than one restart during the day. The machine this is running on is a Xeon 500 MHz with 512 Mb of memory. Zope is a very memory intensive application, but 512Mb used to be enough for a medium sized portal. This Zope site makes very heavy use of both ZClasses and ZCatalog, and it appears to me that this worsening of perfomance and memory consumption was being caused by the increase in content, which caused an increase in the size of the ZCatalog and in the number of ZClass instances. A total of 6796 ZClass instances representing News Items are cataloged. There are other ZCatalogs and ZClass instances representing calendar events and other stuff (this is a very old Zope portal coded by hand in ZClasses, no CMF, no Plone, not even Pagina1, our ZClass based CMS) Fiddling with the cache parameters in the control panel showed that while we could keep the memory consumption to a point where the daily restart would be enough (say, with 10k objects per thread), we would get constant thrashing of cache objects, specially DateTime objects due to the ZCatalog queries, and the machine performance would be close to intolerable, whereas if the cache parameters where set to allow a fast performance (with 50k objects per thread) the machine would run out of memory in 3 to 4 hours. Needless to say this was with heavy use of RAMCacheManagers, not counting the accelerator proxy in front of it. Without the RAMCaches, the machine would go down in under 5 minutes of work hour load. Even with the caches on, the load would never go down from 2.0 during work hours. Last tuesday we decided no longer to wait for 2.6.2 and migrated the site to 2.6.1. We dealt with the ObjectManager-based-ZClass issue, reformed the ZCatalogs to replace the DateTime FieldIndexes with DateTimeIndexes and then had a working testing environment, which we stress tested lightly without detecting any problems and quickly moved to production. This was late at night The next morning we were surprised to notice the machine very quickly ran out of memory. The memory leak was *far more severe* than before. Zope needed a restart every 15m or so before it would send the machine into heavy swaping. In a very non-intuitive hunch I suggested we shut down all RAMCaches and, amazingly enough, this made the situation a bit more manageable. We're now restarting every 45 minutes. To our relief, disabling the RAMCaches had only a barely noticeable effect on performance. The site kept churning out pages really fast, a testatment to the optimization job done in the 2.6 series. The load on the machine is rarely above 0.8, except when it goes into swap :-) The number of DateTime refcounts in the Control_Panel, although much smaller than in Zope 2.5.1 is very high and, mostly importantly, constantly increasing, as far as I can tell. After 12 minutes of uptime, the top refcounts are: DateTime.DateTime.DateTime: 96168 BTrees._IOBTree.IOBucket: 43085 BTrees._IIBTree.IIBTree: 40400 BTrees._IIBTree.IIBucket: 23696 OFS.DTMLDocument.DTMLDocument: 23190 BTrees.OIBTree.OIBucket: 14582 BTrees._IIBTree.IISet: 12479 BTrees._IIBTree.IITreeSet: 10823 BTrees.OOBTree.OOBucket: 7088 OFS.Image.Image: 6860 OFS.DTMLMethod.DTMLMethod: 5894 DocumentTemplate.DT_Util.Eval: 3250 OFS.Image.File: 2796 BTrees._IOBTree.IOBTree: 2761 ZClasses.Method.MWp: 1592 In time, DateTime refcounts eventually dwarves the second place by an order of magnitude. I think this is related to the fact that DateTime instances are stored as metadata, even though the date indexes have been converted to DateTime indexes. The question is, why aren't those instances being released? What is holding on to them? I tried installing the LeakFinder product but discovered it didn't work before stumbling in a message in the archives that told me exactly that :-) The RefCounts view in the LeakFinder object fails with the following traceback: Traceback (innermost last): [...] Module DocumentTemplate.DT_Util, line 201, in eval - __traceback_info__: REQUEST Module string, line 0, in ?

Zope is transactional, but products like ZLDAPConnection have the ability to be non-transactional what does this mean? Could I use this in my counter? the meaning of transactional as employed by the ZLDAPConnection has nothing to do with your concern about ZODB bloat. the ZLDAPConnection tried (it never got successfully finished) to hook into the ZODB transaction machinery to make sure writes to LDAP only happen if the whole transaction was indeed successful. i personally don't see a way to completely avoid ZODB bloat with a counter product stored in the ZODB itself.

As a matter of fact I am not even sure whether the log entry means
that the 'detail_view' document has changed (which of course it
hasn't), or something along the traversal path caused a ZODB write.

Re: [Zope-dev] find unused objects: hopefully the last misunderstanding...
extremely expensive. you would have to... - assemble a list of all objects IDs in the ZODB and then... - parse all contents of all objects and check against that ID list. you would probably need a little counter for every single ID that gets incremented upon finding its ID referenced, and all those that are left over with the counter at 0 in the end would probably be candidates for removal. this schema will fall down the moment your object IDs are not unique across the whole ZODB. besides, every object is potentially different in how you access and read its contents. if your whole intent is to have a cleaner ZODB and there is no pressing reason to do this cleanup, i would just forget about it. jens On Friday, Aug 30, 2002, at 07:48 US/Eastern, [EMAIL PROTECTED] wrote: * Starting at root, check all objects if they are referenced, * and produce a list of those which are not, for cleanup purposes. * Packing the database cleans up in this manner.

This, as expected, kills that entire transaction which was never committed. Is it known that large numbers of operations, such as above, in a single transaction can cause problems?

Re: [Zope-dev] DB.py: pool_size
there is a common misconception that the number of threads and the pool_size defined in ZODB/DB.py are the same. they are not. number of threads is just that: the maximum number of threads the zope process will spawn (excluding extra threads, such as those used for zDaemon). the pool_size in ZODB/DB.py sets the number of ZODB database connections that are used by the application to interact with the ZODB. increasing the number of threads alone does not make much sense because no work can be done if a thread does not have a database connection out of the pool. you might try to carefully and slowly increase both numbers *in a sandbox, not on your live site* and test to see if it helps. jens On Saturday, May 4, 2002, at 01:00 , HoYin Au wrote: We've been experiencing some extreme lag on our Zope site lately, and have noticed that the bottleneck seems to be the 7 thread limit placed on ZODB.

Re: [Zope-dev] 2.5.0b4: how to deadlock/DoS your Data.fs
you're explaining the symptoms again, but i think the main issue here is about reading the documentation. take SiteRoot as an example. i type siteroot into the searchbox at zope. org and already the first two hits talk about the _SUPPRESS_SITEROOT thing, the second one with an example even and telling byou to do this if you lock yourself out. so the documentation is available. as far as the Virtual Host Monster goes, it only reacts when it sees specially rewritten URLs that ususally get set in your apache configuration. it does not do anything if your zope itself listens on a HTTP port and you enter the management interface that way. just like with anything else, a software author cannot prevent people from shooting themselves in the foot if they don't know what it is that they are installing or how it really works. jens On Tuesday, January 22, 2002, at 01:53 , Pierre Fortin wrote: Well... pointing my browser to http://localhost:8080/manage gives errors due to everything getting re-written to entities which don't exist yet; the frameset's three frames point to http://localhost:8080/fubar/manage* which are not setup. ^^^ ^ My point is that it is way too easy to (yes) toast your ZODB as a result.

vio,
i'm not sure what user folder products you were looking at, the
CookieCrumbler is *not* a user folder.
normal user folders do not use BeforeTraverse.
look at the source for the stock user folder
(lib/python/AccessControl.User.py), it is pretty much the simplest
implementation around.

You must be referring to the routine

called with REQUEST.RESPONSE.unauthorised(). It just happens that I really
don't like that 'Basic Authentication' dialog, that's why I want to use
mine.
So I've done half of the job to that end, only remaining problem is to
switch
'programmatically' to the new authenticated user id. Doing something like
'REQUEST['AUTHENTICATED_USER'] = my_custon_loginForm_loginName' seems to
have
no effect, because the user is still 'Anonymous User' (found with
'AUTHENTICATED_USER.getUserName()'). If only I could understand where
REQUEST
gets its data for its 'AUTHENTICATED_USER' attribute, I could simply
change
that data source, and I'd be done. But I don't still understand how
REQUEST
gets all the data to its attributes.
you don't set the user manually.
Of course you do ('programmatically' not 'manually'), as proven by all the
customised 'login' products out there, who are doing just that.
Only the one I studied so far
(CookieCrumbler) seems to re-write the REQUEST.RESPONSE at each traversal.
Which to me seems like a lot of overhead. If someone could point me to
where
Zope keeps user state (I believe with a cookie on the user's browser,
but where in the source does Zope set this cookie up?),
I could simply re-write that cookie with the new User ID ... Just a
thought of a simple and elegant solution (aka 'magic bullet') for my

Re: [Zope-dev] Zope server speed
what i have done before to get around the speed penalty is to create an external method. the external method calls the ZSQL method directly and iterates over the result objects to pull out all interesting attributes and stick them into simple python objects, in this case i returned a list of dictionaries from the external method. in DTML the iteration over it still looks the same but it was much faster because there is no security enforced on the simple python objects returned from the external method. jens On Thursday, December 6, 2001, at 09:33 , MANOTTI Alessandro wrote: Thank you for your suggestions (thanks to Matt).

I have a sample database in Oracle of US Zip codes -- it has about 45,000 records in it. I can pull this into DCOracle2 on the C adapter side (dco2.so) in less than a second. However, wrapping each result cell in a python object blows that up into about 9 seconds. If I were to iterate over the whole thing in Zope (which I haven't timed) it would get a LOT longer, because Zope is enforcing policy on every object accessed. So, one of the ways to make that go faster is to use python modules 'outside' of Zope (ie external methods) to perform large calculations which takes a ZOracleDA connection object to get a cursor object on the database, does the query directly, and formats and returns the results. I realize this isn't ideal, but Zope is not optimized for the case of extract thousands of records from the database and format them in a huge table. Zope likes extract hundreds of records from the database and format them in a big table instead. With each release, Zope has more features that enable you to program through the web, but when you're doing performance intensive calculations, it's usually time to write a python module and plug it in to zope (via an external method, or by writing a product).

Re: [Zope-dev] LDAP
magnus, the LDAPUserFolder has SHA password handling hardcoded into it. in order for it to produce crypy passwords you'd have to look up the few places where it creates a password and change it to use crypt. i chose SHA because to the LDAP server itself it does not make any difference whether it's SHA or CRYPT and SHA is marginally more secure. as far as your login problems go, look up a user record on the Users tab and see if that record has any roles associated with it. you must also ensure that the user record you are trying to retrieve has permissions inside LDAP to look up itself and permission to look up the groups associated with it. the ACLs in slapd.conf govern that piece. you could use ldapsearch to emulate these searches by binding with the respective user's DN and passowrd and looking up its own details as well as its own groups. jens P.S.: LDAP and trying to use it for zope authentication can be very painful to set up if you're not experienced with LDAP first. there are a *lot* of factors and pitfalls involved. you must have a good understanding about how LDAP works, knowledge about LDAP schemas and LDAP ACLs.

well, the actual extension does not matter. you could as well specify something like --with-suffix=.mary_had_a_little_lamb if you wanted... for a more technological explanation, when the compile is done the executable is copied into the root of the python source tree. by default the name of the executable is python. this would not be a problem if it was not for the case insensitivity of the HFS file system used by most OS X users. there is a folder named Python in the root of the tree as well. trying to copy python into the root will fail because it collides with Python. the --with-suffix will produce a binary with that suffix and that will avoid this collision. jens On Wednesday, October 3, 2001, at 11:03 , Leonardo Rochael Almeida wrote: Mitchell L Model wrote: [...] With the updates for OS 10.1 in Python 2.2a4, all I had to do to make both Python and Zope was: cd Python2.2a4 configure --with-suffix=.exe make sudo make install cd Zope python wo_pcgi.py I don't know if it's just me, but this --with-suffix=.exe, on an Mac OS (the OS where you weren't suppose to need extensions) is extremely disturbing. :-) Cheers, Leo PS: and I'm not a Mac user, just a Linux user who would like more metadata in his operating system.

Wonderful! Thanks!! Great information.
Having said that, and having spent a couple of hours experimenting, let
me try to clarify things a bit:
1. Python 2.2a4 defaults to --with-dylib, so you don't need that when
making Python 2.2a4 as you did for 2.1.
2. Likewise, you don't need to set OPT the way the 2.1 README says for
Mac OS 10.
3. Similarly, the Python2.2a4 configure.in knows to add -flat_namespace
to Makefile.pre and therefore Makefile.
4. Both 2.1 and 2.2a4 correctly specify -undefined suppress.
So, whereas I did need to fix the Python 2.1 Makefile to build it, I didn'
t need to fix the Python 2.2a4 Makefile to build it. (I guess I didn't
try building Python 2.1 yesterday, or I would have realized the problem
wasn't in Zope, but in Python, as you discovered.)
From my experience this evening, I'm surprised that fixing the Python
Makefile would allow you to compile Zope. It turns out that the zope
configuration process uses the Makefile.pre.in installed in (typically)
/usr/local/lib/python2.{1,2}/config. It also turns out that although
Python 2.2a4 correctly adds -flat_namespace to Makefile.pre and Makefile,
it doesn't add it to Makefile.pre.in! So for both 2.1 and 2.2 I had to
add:
LDSHARED= $(CC) $(LDFLAGS) -flat_namespace -undefined suppress
to Makefile.pre.in, either in the Python src directory before doing 'make
install' or in the /usr/local/lib/python2.{1,2}/config after doing the
install.
I'll report this problem to the Python developers. Thanks for you hints
and your careful reading of the fink documentation on shared libraries.

Re: [Zope-dev] compiling Zope 2.4.1 on Mac OS 10.1
i think i found a working solution. since my knowledge of compilers and
linkers isn't the greatest i'll just explain what i did.
trying to compile python2.1.1 on OS X 10.1 failed for me displaying the
very same error. searching through apple's discussion i found the
following link:
http://fink.sourceforge.net/doc/porting/shared.php
it explains that some linker/compiler default options have changed. in
order to get python compiled and running i edited the toplevel Makefile
after running ./configure and edited the lines starting with LDSHARED and
BLDSHARED, this is what they look like now in my setup:
LDSHARED= $(CC) $(LDFLAGS) -bundle -flat_namespace -undefined suppress
BLDSHARED= $(CC) $(LDFLAGS) -bundle -flat_namespace -undefined suppress
notice the -flat_namespace switch, this gets rid of the new default
twolevel_namespace that complains about undefined warning.
running make was now successful and i was able to compile and run Zope 2.
4.1. you will probably have to recompile your python to set that switch
under 10.1.
i only did some light testing, no guarantees and before using this in
production you might want to read up on those compiler/linker options...

Re: [Zope-dev] Structure-text : html
AFAIK this is the right behavior and not a bug. you ask for the StructureText document to be rendered and you inform the rendering machinery that the document is in structured text. the rendering process will output HTML. i think what you want is to simply say dtml-var StructureTextDoc without the fmt flag. that should get you the raw structured text. the rendering process then assumes the document is already in some kind of HTML format and does not try to generate HTML tags. jens On Thursday, September 20, 2001, at 07:14 , Sin Hang Kin wrote: When I use dtml-var StructureTextDoc fmt=structured-text I got html /html in the result.

Re: [Zope-dev] ZPivotTable doesnt save its data dictionary
florian, without even looking at the code, when you use simple data types (lists, dictionaries, etc) to store your data you have to make sure that the persistence machinery gets tickled the right way whenever you update values. with those simple storage datatypes it won't know things have changed unless you specifically tell it. you would need to do either something like this:: self.my_storage_dictionary['newvalue'] = x self._p_changed = 1 or you could do it like this: dictionary = self.my_storage_dictionary dictionary['newvalue'] = x self.my_storage_dictionary = dictionary or you could simply use one of the helper classes that come with zope, like PersistentMapping. it emulates a dictionary and makes sure the persistence machinery gets told about changes. jens On 5/12/01 10:27, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Hi folks, I've started to program a pivot table.

[Zope-dev] [ ANN ] LDAPLoginAdapter 1.1 released
LDAPLoginAdapter 1.1, a user folder replacement that authenticates against an LDAP server, has been released. You can view some of the documentation and download the software at http://www.dataflake.org/software/ldaploginadapter/ A Tracker at that same address allows you to easily file bug reports or feature requests for this product. Improvements and bugfixes since the last announcement include: **LDAPLoginAdapter 1.1** Features Added: * Instead of hardcoding fixed publicly available attributes onto the LDAPUser object you can now take full control of the mapping from LDAP attribute to public user object attribute. A public user object attribute is an attribute that is directly accessible on the user object. DTML code like "AUTHENTICATED_USER.email" is an example of accessing a directly accessible attribute on the user object. A lot of legacy DTML code relies on such attributes. Bugs fixed: * finduser() now lowercases all DN records from valid groups and compares it to a lowercased DN from any search results among user records. This fixes records not showing up if the capitalization in the group and on the user record is different. * When a user object was created the code expected a "mail" attribute on the LDAP record to set the email attribute used for compatibility with the Tracker. This has been repaired and will just default to an empty string. * Users who use tools like PADL's migration script end up with records that do not have the expected "sn" attribute. This is not set to a default value in finduser() to avoid errors in case it is not there. This will make the LDAPLoginAdapter compatible with user records of type posixAccount. **LDAPLoginAdapter 1.0** Bugs fixed: * Due to a bug in checking the return values from an LDAP search the cache can be polluted by invalid records for failed logins. This did not constitue a security breach, just more processing than necessary. **LDAPLoginAdapter 1.0beta3** Bugs Fixed: * Moved the LDAP search scope translation list from a volatile attribute on the LDAPLoginAdapter to a module-level attribute. This avoids any re-initialization calls. * Eliminated the extra attribute _v_loglines that counted the length of the log. A simple call to len(self._v_log) replaces it where log length info is needed. * Created one centralized method that handles connecting to and searching the LDAP server. This allows centralized error handling and makes for less and cleaner code. So far finduser, getUserDetails, getGroups, getUserNames and _lookupuser have been converted to use it instead of having their own connection code. * Rooted out error that would put a known user into the cache even though the password was not matched. This was not a security error since the broken user had the wrong password and failed any tests in validate() * Rigorous pruning of overly long lines of code to pare everything down to 80 chars width max * Avoiding unnecessary calls to the logging routine by checking for the correct log level *before* the call and not in the logging method. * Added a file, SAMPLE_RECORDS.txt, that shows a sample group- and user record. This will hopefully make it easier to understand the types of LDAP records needed. Features added: * Nicer Search screen adopted from the LDAPUserManager ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Maybe I've overlooked something in the Zope documentation but could someone supply a useful snippet of code to get me started?

Re: [Zope] multiple unknown parameters - ZSQL
this could be done in python in either an external method or python script/method. you can execute arbitrary SQL (which you would dynamically generate in python) on a database connection using the "query" method that is part of every database adapter. you need to - get a handle to your database connection by *calling* the database connection you have in your ZODB, like "db_conn = self.mydbconnection()" - once you have constructed the string carrying the SQL for one update statement you can pass it as argumant to the query method on the database connection, like "result = db_conn.query(sql_string)" looking at that page you put up you will have to create a SQL string for every student shown on the page and pick the correct variables from REQUEST for the SQL update statement. jens on 1/9/01 17:10, Lee at [EMAIL PROTECTED] wrote: Hi, As usual, I'm finding this one hard to explain... so I've described it with the aid of a diagram @ http://homepages.strath.ac.uk/~aeu97172/h.htm I realise that this may be more of a burden on your time than a normal request... but I'm hoping that some of you have met similar problems before and can suggest the best way round the problem.

Re: [Zope] [python] converting int to string?
in python you can do: str(int) and in zope you do it like _.str(int) "Learning Python" by o'reilly is a pretty good beginner's book for python. i suggest you read it. it's well written and gives you the basics. jens on 1/7/01 11:12, Lee at [EMAIL PROTECTED] wrote: Hi, I wonder if anyone could help me here... Is there any way to convert an integer to a string data type in Python? I see there is a facility for accomplishing the reverse conversion (string - int)? I have 4 integers, which are primarily used to handled the logic in the program below (in the while loops). The value of this integer must also be added to a string (as a table column name), which will be used to create a SQL query. Here's a rough sketch of the program: p = 2 # no.of practicals t = 2 # no.of tutorials a = 2 # no.of assignments b = 3 # no.of bomus marks c = "52225" SQL = "CREATE TABLE CLASS" + c + "\n" SQL = SQL + "( \n" SQL = SQL + "matric float, \n" SQL = SQL + "fname varchar, \n" SQL = SQL + "lname varchar, \n" SQL = SQL + "uname varchar, \n" while p 0 : SQL = SQL + "p" + p + " integer, \n" # cannot add type "int" to string p = p - 1 while t 0 : SQL = SQL + "t" + t + " char(1), \n" t = t - 1 while a 0 : SQL = SQL + "a" + a + " integer, \n" a = a - 1 while b 1 : SQL = SQL + "b" + b + " integer, \n" b = b - 1 while b 0 : SQL = SQL + "b" + b + " integer \n" # ',' taken out from last query b = b - 1 SQL = SQL + ")" Of course, I could have a load of statements in the while loops like: if p = 1: pString="1" ... etc. But that would look hella ugly! Another alternative would be to send both the integer value and a string parameter (converted by Zope) in the calling DTML method. This is okay - but is there a better way to do it? As usual, thankyou very much in advance. Is this off-topic BTW? Should I address any future questions regarding Python to a Python newsgroup/list? -- Lee Reilly mailto:[EMAIL PROTECTED] http://www.footkick.co.uk/lee ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
