It has a real level 2 DOM, which XMLDocument didn't. We'd be interested in hearing about what you're planning on the zope-xml mailing list. -- Karl Anderson karl(a)digicool.com

RE: LoginManager and LDAP

I was able to do a basic test with LoginManager and ZLDAPConnection/ZLDAPMethods using Zope 2.2.4: In UserSource added these Python Methods: ------------------------------------------ userAuthenticate: parameter list: self,REQUEST,username,password function body: return self.ldapAuthenticate(username,password) ------------------------------------------- userDomains: parameter list: self, REQUEST, username function body: # I don't use this for my ldap implementation return [] ------------------------------------------- userExists: parameter list: self,REQUEST,username function body: return 1 ------------------------------------------- userRoles: parameter list: self, REQUEST, username function body: # call ldap method to get information on user results=self.getUserInfo(uid=username) row=results[0] return row.get('roles') ------------------------------------------- ldapAuthenticate: parameter list: self,username,password function body: # call ldap method to get information on user results=self.getUserInfo(uid=username) # an external method that returns an md5 encrypted password password=self.md5_encrypt(password) if len(results)==0: return 0 elif len(results)>1: return 0 else: row=results[0] # userpassword is the name for the password in the ldap directory if row.get('userpassword')[0]=="{MD5}%s"%(password,): return 1 else: return 0 --------------------------------------------- Added this LDAPMethod: ------------------------------------ getUserInfo: parameter list: uid query filter: uid=&dtml-uid; --------------------------------------------- Hope this helps, Corey

devel/production syncronization
by Gary Lowder 21 Feb '01

21 Feb '01

I'm having problems trying to figure out how to keep the production version of my app synchronized with the developement version. I need to be able to work on an app on my laptop, then move those changes onto my production versions of the application spread around several sites. Since when in use, the production app's data changes quite a bit, it's not as easy as just copying over the whole site, I'd overwrite a lot of data. It'd be nice to have an option on export/import to do something analagous to applying a diff to a file. It'd also then be easy to apply to several different sites running the same app. Any help would be appreciated. Gary.

hrm, wait, my last suggestion won't work, you can't just export /, and it'd carry all the data below it anyway. How do you put all of your logic away in a folder, off of say /, and have your data also in a folder off of /? i.e. how would accessing /datafolder/method, know that method was in /methodfolder/method ?

RE: [Zope] Zope hosting services?

I would recommend Hurrah (http://www.hurrah.com/) who host one of my Zope websites.They charge me $25/month and host my Zope site. I believe the package includes unlimited email accounts but you'll want to double-check that. They are the most cost-effective host I've found. Also, you fully control your own installation so you can put whatever products or customization in that you want. When I signed up, 2.2.x was current so that was what was installed for me at the time. I suspect they will now install 2.3.0 for you if you ask. -- Kit O'Connell Zope Administrator kito(a)clearcommerce.com 'yes is a world & in this world of yes live (skilfully curled) all worlds' - e.e. cummings -----Original Message----- From: Scott Chapman [mailto:scott@lund.com] Sent: Wednesday, February 21, 2001 2:14 PM To: zope(a)zope.org Subject: [Zope] Zope hosting services?

Good idea, I'm afraid I may have to do that. I could move all of my methods/SQLmethods, etc into my /, and they'd be available by acquisition (they're not used for anything else, so I'm not worried about polluting my /). As it is, my logic is all in the same folder as the base of my data, which isn't optimal I guess. Gary.

search & edit

I'm about to start building Zope w/PostreSQL search and edit forms. As I do much better working by example, I'm wondering if there are examples (I'm happy to just go to the site and reveal codes to figure out what I need to do) or instructions that I should look at before I begin (other than the Z SQL Methods User's Guide). -Don

"industries.objectIds()" will return the list of id's in the folder "industries" (provided "industries" is accessible by acquisition in the current context). Reading the official Zope book or URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html may help you answer such questions. > b) Objects, references and ZODB > > Suppose I successfuly assign an industry object to an organization object, > how is that persisted in ZODB? I mean, does the organization object only > keep a persistent reference to the industry object, or does it copy the > industry object entirely? What is the proper way to handle such cases > in Zope? Copying the industry object would be a bad idea. Logically, the industry object exists independent from the organization. Therefore, the organization should only reference it but not have its private copy of it. As suggested above, you would give the organisation a property "industry" that contains the name (aka id) of the industry object. > c) "mutable sub-objects should be treated immutably" - from a ZODB point > of view. > > I am not sure I completely understand this (I understand mutable and > immutable allright, but I do not see what makes a mutable object being > treated immutably, and how/why it affects ZODB). Python, per se, does not support persistence. To get persistence, Zope objects inherit from class "Persistence". This class tries to detect changes to an object, as, when the object is changed, the modified state must be made persistent. The class detects when you directly change an attribute of the object. Thus: o.attr= xxx is detected. However, if an attribute value is mutable, you can change the attribute value without changing the object: o.attr.append('xxxx') would append 'xxxx' to "o.attr" (assumed, this is a list) without any change to "o". The persistence machinery would not detect, that "o" has been changed and a new value must be made persistent. The change would probably got lost eventually. There are two options: 1. avoid such modifications (treating mutable attributes as immutable) in the example above, you could use alternatively: o.attr= o.attr + ['xxxx'] You recognize the explicit assignment? 2. tell the persistence machinery about the change. You do this by setting an attribute to a true value. I think, it is "_p_changed" but it might have a slightly different name. I think, 2. is the far superior option. Dieter
