'lambda' is actually a keyword, not a function, and hence works fine in PM0.1.7. 'map()', 'filter()', et al., were deemed to be susceptible to being used in DOS attacks, and hence are not permitted in through-the-web code (they would need to be added to the '_' namespace, like 'str()', et aliae).

has_permission in PythonMethod
by Stefan H. Holek 30 Nov '00

30 Nov '00

I have this (internal) PythonMethod called filtered_meta_types user=self.REQUEST.AUTHENTICATED_USER meta_types=[] if callable( self.all_meta_types ): all=self.all_meta_types() else: all=self.all_meta_types for meta_type in all: if meta_type.has_key( 'permission' ): # this is always false :( if user.has_permission( meta_type['permission'], context ): meta_types.append( meta_type ) else: meta_types.append( meta_type ) return meta_types I do not get why the 'has_permission' condition is always false If I mimic this function in DTML (yuk), it *does* work. TIA, Stefan -- Things work better when plugged in

New Zope.org
by emf 30 Nov '00

30 Nov '00

Zopatistas! Zope.org is finally living in its new home. Right now, you may be getting zope.org through the old apache, so don't be surprised if it's a tad slow. By late tomorrow, just about everybody's dns should have updated to the new IP address. If you want to know, do a nslookup www.zope.org: you should get 63.102.49.33 as your answer. When I finally wake up tomorrow, the first thing I'm going to do is start working on a write-up of what the new zope setup is all about. Thanks for your patience! ethan mindlace fremen Zopatista Community Liason

sqlgroup
by Tom Deprez 30 Nov '00

30 Nov '00

Hi, Is there a reason why the attribute 'having' doesn't exists? I want to use <dtml-sqlgroup having> <dtml-sqltest ... optional> </dtml-sqlgroup> this way when the sql-test tag contains nothing, also the having clause is not attached to the query. Why does 'where' exists and 'having' not? Is there another way to mimic 'having'? Thanks, Tom.

RE: [Zope] date in Z Gadfly Database
by Farrell, Troy 30 Nov '00

30 Nov '00

Note that Gadfly does not support the DATE datatype. You can use VARCHAR to store a string, or switch to a different database, such as PostgreSQL (my personal preference) or MySQL. The answer to your question is found here: http://www.chordate.com/kwParsing/gadfly.html#table The main Gadfly pages are here: http://www.chordate.com/gadfly.html Troy -----Original Message----- From: Angietel [mailto:angietel@hotmail.com] Sent: Thursday, November 23, 2000 2:16 AM To: zope(a)zope.org Subject: [Zope] date in Z Gadfly Database When i create a table, one of the fields is consider as date type, but the Z Gadfly Database does not allow me to do that, it only accepts INTEGER instead of DATE type. The following is my SQL for creating a table:- CREATE TABLE customer (custid VARCHAR(10), custname VARCHAR(15), custactdate DATE, custadd1 VARCHAR(30), custadd2 VARCHAR(30)) Please let me know if i got an error.Thank You.

Hi Zopistas! When users connect to a restricted area a dialog box pops up that looks more or less like this: ------------------------------------ Enter user name for Zope at myhost: User: _________ Password: _________ ------------------------------------ Where and how can I change the content of the first line so that it would e.g. read "Enter user name for funky stuff at myhost"?

I think we need to distinguish between "support" and "consulting". DC is primarily a *consulting* company (we build custom software for our clients), which also sells support contracts for Zope. Because the PTK is not (yet) a "released product", we don't (yet) sell support contracts for it; we *do* use it in consulting engagements, however.

mysql & zope
by Alexander DePauli 30 Nov '00

30 Nov '00

Hi Zopistas! we are looking for a method to do a better integration of mysql 3.23.27 with zope 2.2.2. (we are using the Z MySQL database adapter Z MySQL DA 1.1.3.) We have to store data in a mysql database - we can´t use ZODB because we need the data accessible by other programs via ODBC. We habe implemented several ZClasses like "customer", "product" and "orders". We store their instances (eg. each product, customer and so on) to the mysql-database. Our problem: we can´t use the standard ZOPE management interface to manage the objects, because the methods of this interface store content to the ZODB - and not to the mysql-database. Is there a way to extend the standard ZOPE management interface with additional mysql statements? For example: we select an object in a zope folder, press the ZOPE Delete-Button, then this object is deleted on the mysql-database, not on the ZODB? For each zclass (customer, products, orders) we need these extra methods (Delete, Update, Insert ...), so our thought is that we would prefer to use the ZOPE management interface to do this instead of programming "extra methods" which obviously can't be used within the standard ZOPE management interface. Hope there is somebody out there with an similarly problem solved. best regards Ruediger ~~~~~~~~~~~~~~~~~~~~~~~~~ http://www.herrenausstatter.de - Der Online-Herrenausstatter Kostenlose Serviceline: 0800 -999 66 33 Versandkostenfreie Lieferung - 30 Tage Rückgaberecht ~~~~~~~~~~~~~~~~~~~~~~~~~ Verwaltungsadresse: DePauli.com Aktiengesellschaft Stahlgruberring 3 - 81829 München Telefon: 089 / 530 75 170 - Telefax 089 / 514 50 666

Re: [Zope] Why GUF or Loginmanager??
by Oliver Bleutgen 30 Nov '00

30 Nov '00

> Hallo, > I'got a fundamental question: > Why should you switch from the built-in authentication mechanism to a > product like GUF or Login-manager?? You can choose the storage for your userdata yourself, which may be practical for i.e. - huge user base and/or you also like to store adresses etc. easily. - adding/changing users through mechanism outside of zope - verifying users through mechanism outside of zope (ie. apache's various mod_auth_*) for tasks outside of zope (try to stream a .rm-file only to built-in authenticated users) cheers. oliver
