How about a Zope 2.3a1, ZBook 2.3a1, and Python 2.3a1
by jimbo 12 Dec '00

12 Dec '00

Just a thought. About a month ago this would have sounded far fetched, but now that Guido is in the house, when might we expect the Zope Python version to change from 1.5.2 to 2.x? Imho for the book the Python version for Zope should at least be 2.xa1 It seems to me that by the time the book is finalized your team could deliver a basic core Zope 2.x Python 2.x release. My understanding is that its not that big of an issue. I'm sure it would just make the marketing team giddy. -Jimbo

If you are working with MySQL or some other database system, then your database should deliver a valid id. For a description have a look in the HowToDos and search for: Creating a new record with subrecords in MySQL Best regards Arno > Hi! > > I have a form that is used to insert some records to a database, and one > of the fields is a sequence number.

Yeah, that bit me too. I think that the alternate approach in my writeup below avoids it by not telling the UserSource anything until everything else is set up. The main problem with it is that it doesn't currently take advantage of the cacheing features in BasicUserSource. I think that I need a trivial Python subclass of LoginUser that supports cache management, but I need to understand the lifetimes of virtual ZClasses in Racks a bit better first... > My solution was to create all the methods needed but with bogus names, such > as by sticking an x as the first character of each. > > This way you can test each in isolation and when satisfied that they are > correct, rename them all in one fell swoop.

RE: [Zope] LoginManager broken?
by Mayers, Philip J 12 Dec '00

Ye gods... Ok, steps I had to take to get LoginManager working 1) Create a folder, call it "test" 2) In that folder, add a LoginManager with a GenericUserSource, with *just* "Basic Auth Login" selected. Leave the rest as defaults. 3) In the newly-created ACL-users folder, you'll find "forbiddenPage", "loginForm" and "logoutForm" - you can delete loginForm. Give logoutForm and forbiddenPage the "Manager" proxy role 4) In the UserSource folder/object underneath acl_users, add a) A connection to the SQL database you'll be using b) an SQL method "check_user" with a parameter "username", which does a "select username from usertable where username = <dtml-sqlvar username type=string>" c) an SQL method "check_user" with parameters "username" and "password", which does a "select username from usertable where username = <dtml-sqlvar username type=string> and password = <dtml-sqlvar password type=string>" d) an SQL method "get_roles" with a paramter "username" that does "select groupname from group_members where username = <dtml-sqlvar username type=string>" (or whatever is appropriate for your database) 5) Add the DTML methods WITH A DIFFERENT NAME - DON'T add userAuthenticate,userExists,userRoles - add (say) xuserAuthenticate,xuserExists,xuserRoles a) xuserExists should read: <dtml-in "HDB_check_user(username=username)"> <dtml-if "_['sequence-item'].username == username"> <dtml-return "_.int('1')"> </dtml-if> </dtml-in> <dtml-return "_.int('0')"> b) xuserAuthenticate should read: <dtml-in "HDB_check_password(username=username,password=password)"> <dtml-if "_['sequence-item'].username == username"> <dtml-return "_.int('1')"> </dtml-if> </dtml-in> <dtml-return "_.int('0')"> c) xuserRoles should read <dtml-call "REQUEST.set('ret', '')"> <dtml-in "HDB_get_roles(username=username)"> <dtml-call "REQUEST.set('ret', ret+' '+groupname)"> </dtml-in> <dtml-return ret> 6) Give the "Manager" proxy role to the DTML methods, so they can access the SQL methods you just created 7) Turn off acquisition of the permissions on the test folder, and be sure to add read permissions to any local roles you're using 8) Make a copy of the test folder now, before it all goes wrong... 9) Batch rename the DTML method (e.g. s/x(.*)/$1/g in perl-speak) - if you're lucky, it will work. I have to say, I'm not hugely impressed...

namespace-problem
by Alexander DePauli 12 Dec '00

12 Dec '00

Hi everybody, what I want to do is fairly simple, but I've got a namespace problem: - via a form I want to add a new folder, add some properties to the new folder, then add a DTML document within the new folder. - whatever I try, the properties as well as the new document are added to the parent folder of the new folder instead of to the new folder. Here some experiments (don't look at the syntax): <dtml- call "manage_addFolder (NewFolderName)"> <dtml-with "_.getitem(NewFolderName)"> <dtml- call "manage_addProperty (ID,...)"> <dtml- call "manage_addDocument (ID,...)"> </dtml-with> This looks fine to me, but ZOPE insists on creating the new document in /OldFolder instead of /OldFolder/NewFolder Some more stuff for wondering: If I do a <dtml-with "_.getitem('NewFolder')"> <dtml-var "_.getitem('NewFolder',0)"> to get an actual value for testing purposes, ZOPE returns the *correct* value of 'NewFolder' But if I do an additional <dtml-in objectItems> id: <dtml-var sequence-key>, type: <dtml-var meta_type> </dtml-in> to list the objects of the actual namespace (placed *after* the above <dtml-with..>, the output consists of the objects of the /OldFolder-namespace, but not that of the /OldFolder/NewFolder. ...I'm sure this is a rookie-problem and can be solved by turning a switch or two (perhaps in my brain), but I'm stuck. Do you/anybody has any clue?

Comment elimination...
by Curtis Maloney 12 Dec '00

12 Dec '00

Greetings, Whilst developing, i often <dtml-comment> out some part of a document so I can test an replacement/option/something. Sometimes, due to interruptions or just my poor memory, I don't remove the old code... I was just wondering if there were some convenient way I could search all of my DTML[Documents|Methods] and ZSQL Methods, for comments, so I could review them? Perhaps it's time I learned how to use ZCatalog? Have a better one, Curtis Maloney.
