programmatically determined multipart MIME
by J. Cameron Cooper 02 Aug '01

02 Aug '01

So I want to be a ble to send an email from Zope that attaches an arbitrary [0..reasonable] number of attachments. You usually do this like <dtml-sendmail mailhost="Whatever"> To: you@localhost From: me@localhost Subject: whatever <dtml-mime type="text/plain" encode="7bit"> test email <dtml-boundary type="application/octet-stream" disposition="attachment" encode="base64" filename_expr="'fileName.txt'"> file contents</dtml-mime> </dtml-sendmail> And there's no problem. But try to do this: <dtml-sendmail mailhost="Whatever"> To: you@localhost From: me@localhost Subject: whatever 2 <dtml-mime type="text/plain" encode="7bit"> test email 2 <dtml-in files> <dtml-boundary type="application/octet-stream" disposition="attachment" encode="base64" filename_expr="'fileName2.txt'"> <dtml-var fileContents> </dtml-in></dtml-mime> </dtml-sendmail> And Zope complains that the 'boundary' tag isn't expected. I quote: " Unexpected tag, for tag <dtml-boundary type="application/octet-stream" disposition="attachment" encode="base64" filename_expr="'fileName2.txt'">, on line X of METHOD" This seems to me like a reasonable thing to want to be able to do. Is there a good reason to forbid this? If there is, I suspect it lies in how the tag is called (I still haven't found that), but the contents of the "in" should be rendered before the "mime" so we should have the parts already, no? Do I have any recourse besides writing the mime stuff myself? --jcc (suspecting)

LoginManager Question.
by Jason C. Leach 02 Aug '01

02 Aug '01

hi, With a normal alc_users authentication I can do: <dtml-var expr="_.SecuretyGetUser().getUserName()"> and it will print out the name of the user that just authenticated. With a LoginManager I always get 'Anonymout User'. What's up with that? I auth agains a python method of my own device, perhaps I need to set a few variables in RESPONSE? j. -- ...................... ..... Jason C. Leach ..

RE: [Zope] Zope v OpenACS and nonprofit application developers
by sean.upton＠uniontrib.com 02 Aug '01

02 Aug '01

The idea that Zope can't be easily used out of the box is rather silly; when I first started playing with Zope in early 1999, I was able to install Zope and setup an internal company knowedge-base by just modifiying Squishdot in about 2 hours. It wasn't that hard at all, and I did not need to set up a RDBMS, or hire a DBA, etc... The other nice thing about Zope: RDB vs. ODB is NOT a forced choice: do both, use whatever is most appropriate to your application. If your argument is that RDBs scale better to Terabytes of data, than why not use Zope as your app server in front of your favorite RDB? If you need Zope to scale/perform, there is always ZEO; it works quite well. Sean -----Original Message----- From: Anders Schneiderman [mailto:aschneid@pop.mindspring.com] Sent: Thursday, August 02, 2001 5:18 AM To: zope(a)zope.org Subject: [Zope] Zope v OpenACS and nonprofit application developers Just to add to Michael's post: People who use openACS have raised two major concerns about using Zope. First, although Zope is easier when starting off, openACS comes a much more developed, integrated system of modules out of the box, and so althought it is more complex, the complexity pays off. Given that our goal is to build open source apps that work well for larger as well as smaller organizations, this is an important consideration. The much more serious issue is whether openACS scales much better than Zope does. People who use openACS say that its model can handle much larger apps, due in large part to the fact that openACS is built on a very solid, thoroughly tested data model that uses a relational database approach. Given that at least one of the participants, techrocks, needs a platform that can handle tons of people, this is a pretty big issue. So, as someone participating in the discussion over platforms, I'd be very interested to hear from people who have used Zope to build large scale applications. In particular: 1) How large of an application have you been able to build with Zope without seeing serious performance problems? I.e., how many users, hits per day/hour, etc.? 2) When you build a large-scale application in Zope, do you have to use a RDMS on the back end? Is there a point at which Zope's object system isn't enough anymore? The reason this is important to us is that there are lots of advantages of using an object system, but if you need to rewrite the backend into a relational database as the app gets larger, then openACS, where the database is there at the beginning, starts to look like a better deal. Any thoughts/comments would be extremely helpful.

can one rename the "manage" id
by Albert Ting 02 Aug '01

Is there a way to rename the "manage" id to something more cryptic? I'd prefer to try and "hide" this page once the zope site goes live. Thanks, Albert

Folder visibility
by Jason C. Leach 02 Aug '01

02 Aug '01

hi, I have a similar security question to the one you helped with this morning. I have a folder 'Clients', that only managers can access. Under it I have folders for 'Client1', 'Client2' and so on. The problem I have is when Client1 authenticates the get access to there folder, but if they change the URL they can access Client2's folder as well. I don't want that. I have my acl_users in the 'Clients' folder because I don't want to create a acl_users for each client since they only have 1 user each. But if I have to do this I will. Is there a better way? Thanks, jason. -- ...................... ..... Jason C. Leach ..

Int to String
by Alexandre Aguiar 02 Aug '01

02 Aug '01

Im working with folders wich the ids are the years (2000, 1999 and so on). Im trying to list a folder using the following code: <dtml-with ZopeTime> <dtml-let ano="year()"> <dtml-in expr="ano.objectValues()"> <dtml-var id> </dtml-in> </dtml-let> </dtml-with> The year() function returns an Int, so when I call 'ano.objectValues()' zope does not understand it, because it is waiting a string. How can I turn my Int into a string? Or how can I make this easier? Thanks for the aid

ANNOUNCE: Component architecture chat with Jim and project details
by Brian Lloyd 02 Aug '01

02 Aug '01

Hello all, As some of you know, over the past few months some folks within Zope Corp. have been working on a new Zope component architecture. The new component architecture seeks to make developing for Zope easier by clarifying and simplifying the task of extending Zope. Enough of the preliminary thinking on the new architecture has now been written down to start sharing those ideas and soliciting the input of the community. You can find the materials for this project at: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/FrontPage Specifically, the following pages of the project wiki are key to understanding what is being contemplated: - VisionStatement - ComponentArchitectureApproach - ComponentArchitectureOverview - Glossary We are very excited about the possibilities of this approach, but to consider changing Zope development in such a fundamental way we absolutely need meaningful feedback and input from the Zope developer community on this. If you are a Zope developer, please check out the project above and let us know what you think. Additionally, Jim Fulton will be hosting an IRC chat on Friday, August 3rd at 12:00pm EST on the #zope channel of irc.openprojects.net to answer your questions on the proposed component architecture (please be sure to have read the above pages first!). We hope to see many of you there! Brian Lloyd brian(a)zope.com Zope Corporation www.zope.com

RE: [Zope] Show Viewable folders
by Montagne, Michael 02 Aug '01

02 Aug '01

Apparently checking or unchecking the permission "Access Contents Information" is the key. I was thinking that "View" would designate whether "skip_unauthorized" is triggered. I guess it is because there is a reference to <dtml-var id> in the code. Works good noe though. -mjm -----Original Message----- From: J.

A dtml-in trying to use unauthorized objects will explode, unless you skip them with the skip_unauthorized. There's a bug in (at least) 2.3.3 that screws up the sequence-first/index/last stuff, but I don't think that's relevant right now. But it doesn't let you view unauthorized objects. Either you are authenticated as someone you don't think you are, or your permissions aren't doing what you think they should. --jcc (credentials) _______________________________________________ Zope maillist - Zope(a)zope.org 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 )
