RE: [Zope] replication (was Zope: 5.4, jboss 0.3 million hits wit h google)

I suppose that one issue is that packing in DirectoryStorage uses snapshots so that using something like rsync or cpio+find+nfs for incremental backup/replication to a peer ZSS would need to use snapshots. You can't do this while packing though, because packing uses snapshots. So a replication tool that uses normal history isn't prohibited during packing. This is how I understand this, but Toby may have a different (and likely more correct - and certainly more informed) explanation.

I am not really the person to ask, as I haven't actually done it. But here's the official way to do it as of version 1.1: http://dirstorage.sourceforge.net/replica.html I would naively assume that you *should* be able to replicate by 1) putting the "master" into snapshot mode 2) running rsync 3) taking the "master" out of snapshot mode ... but there may be hidden issues with that; I would kind of assume so, since Toby Dickenson bothered to write the replication tool.

RE: [Zope] Content Management

Hi Don, I've read the responses on your question so far and don't want to argue about whether you should use DTML or PythonScript or whatever. I think however that your problem is in the ZSQL method. The variable names in your database contain capitals. I think for entering (and updating) you need to put the variable names in quotes when you use capitals, otherwise Postgress or Zope (I don't know which one) assumes they are all small caps. So I think it should be: -- UPDATE A1 SET= "A1_Title"= <dtml-sqlvar a1_Title type= "string">, "A1_Author"= <dtml-sqlvar a1_Author type= "string">, "A1_Body"= <dtml-sqlvar a1_Body type= "string">, "A1_Pix1"= <dtml-sqlvar a1_Pix1 type= "string">, "A1_Pix2"= <dtml-sqlvar a1_Pix2 type= "string">, "A1_Date"= <dtml-sqlvar a1_Date type= "string">, "Ai1"= <dtml-sqlvar ai1 type= "string">, "Ai2"= <dtml-sqlvar ai2 type= "string">, "Ai3"= <dtml-sqlvar ai3 type= "string">, "Ai4"= <dtml-sqlvar ai4 type= "string">, "Ai5"= <dtml-sqlvar ai5 type= "string">, "Ai6"= <dtml-sqlvar ai6 type= "string">, "Ai8"= <dtml-sqlvar ai8 type= "string">, "Ai9"= <dtml-sqlvar ai9 type= "string">, "Ai10"= <dtml-sqlvar ai10 type= "string">, "A1_Publish"= <dtml-sqlvar a1_Publish type= "string"> WHERE "A1_IDNum"= <dtml-sqlvar a1_IDNum type= "string"> -- Hope this helps.

Change th Mange-Interface of Zope
by Joerg Luger 13 Feb '03

13 Feb '03

Hello, i'm new to Zope. I think i have a faq-question, but i found no faq. Where could i find one? Is there any possibilty to change to manage interface of Zope. I want to prevent some users of delete or changing the user accounts (at least the ones of the other users). Additional i want to create a workspace where the users are only allowed to do things they need to do but it should also be possible to add easily more features (of the Zope interface e.g. they dont need to add Scripts, but if one does it should be easy to allow this to him) or hide them.

Thank you all for the help and info. I now have the errors coming up properly, thanks Paul. So now I can see what is going on. I was able to trace the root of the problem and it came up to where I was referencing a value that was not passing right. I have changed the reference and BAM! it works. Dario, I am taking your suggestion on Python - I'm hitting the books and info available to trap errors etc through Python. Much thanks, all mighty Zope Mentors. --Don Brooksby -----Original Message----- From: Dario Lopez-Kästen ----- Original Message ----- From: "Paul Winkler" > On Wed, Feb 12, 2003 at 01:14:53PM -0700, Don Brooksby wrote: > > Because in my reading of other emails that are posting to Zope, as > > much info as possible is what is requested, so here are 2 dtml > > methods where I am seeing the failures - no error pages are > > displayed, it just tells me it was not successful writing. > > That's because you caught the errors in > <dtml-try>...<dtml-except>...</dtml-try>. > > Test it again with ONLY the <dtml-call> that > actually updates the table; in particular get > rid of the tags I mentioned. > > That way you'll get a traceback with more information. > Come back and post the traceback and maybe somebody > can help you. Also, Don, you really don't want to use DTML for that kind of stuff. Better to direct the posting of the form to a pythons script ("Script (Python)" as they are called in the ZMI) and then generate error messages form there and then either redirecting to or calling a DTML-method to report errors/success. Doing all that in DTML is way to hard to be worth the effort - been there, done that - and you'll be able to write code that traps errors in a much nicer way than you can do in DTML - and as a bonus you will find that yopur code will easier to write and debug.
