Re: [Zope] How to set proxy roles in dtml method?

Is it possible to do that? It is a bit strange, but as a security feature, you can change an object with a proxy role only, if you have *THAT PRECISE* role. Give your Manager user this role and it should work. In Zope 2.1.6 (which we use still in a production site), this did apparently (I did not dig in and may have been simply confused) not work. However, as Superuser, I could change the object. Dieter

ZDESIGN IDEAS = How to improve 'manage' ?
by Jason Cunliffe 09 Jan '01

09 Jan '01

Hello I am cross poisting this becaese I beleie it merits responee fom both lists.. The need to improve the manage interface has grown urgently clear to me while using Zope myself, designing for all sorts of community and collaborative Zope-based projects, demos for a number of innocent bystanders, interested parties and potential clients. Zope 'manage' is plain primitive at present. Considering the power of Zope, and the real workflow needs of people working with it, imho this present lack of thoughtful user interface makes no sense. By ignoring these basics, Zope is neglecting a #1 self-promotion opportunity - how it runs out of the box, and how quickly one can use it as site-planning/design tool.It is quite unproductive now compared to what it could/should be. I am looking for real help here on how best to improve this... Here is a list of features I believe should be default manage screen behavior now. Please submit your comments and improvements to these improvements: KISS For those who do not want any added features, there should be an option in z2.py or as a manage_config DTML method in "/" or anywhere else in the tree to enable or disable 'advanced manage' features. ----------------------------------------------------------- 1. SORT TABLE 'manage' needs to presented with basic column listings so one can display sort by headings. I am not sure if this turns into a CatalogAware Inferno or whether all this info is already hidden in the ZODB and could be extracted adn cached sensibly and quickly. What do you think? For example some headings I see a real need for: NAME [default now], DATE[created, last modified] SIZE, TYPE[meta-type], USER[default=owner], DEPTH, COUNT, CHANGES, PROPERTY, DISPLAY NAME should be like now, but one needs to be able to group things more sensibly, so that upper and lower-case can be ignored. For example: MYFOLDER, myFolder_config, MyFOLDER_Display could all be grouped together where the probably belong. DATE Fact of the matter is that, during development and very often during normal life, we need to work on things according to the most recent ordering. This is also an invaluable way for people on a development team to see what has been 'happening'. Since Zope is a tool for 'customers who have customers who have customers...' it means that even after the original site DTML/Python developers may have gone home, a Zopesite is under development as long as it is being used and growing. All of those users, especially deserve better means to see and understand how the site is working and to allow them to work better together. SIZE How big is this thing? When I look at a graphic is it a thumbnail icon or a hires scan? What about PDF What about folders - how to calculate the size of folder? TYPE Display objects sorted by TYPE. USER Default sorts by Owner, but could also be designed to sort by last user who accessed the object. DEPTH How many levels below this thing? This would only work for Zope folders. An essential indicator of hidden complexity/importance etc. COUNT How many things are contained here? Targeted mainly for Zope Folders to allow one get a good quick overview of site structure without needing to click though a lot of trees of nested manage screens. CONT could be nicely integrated with DEPTH feature above to make for a more compact interface. If the object is not Folder-like, then COUNT could perhaps be used to display references or some such. In other words, how many times is this object referred to explicitly? I realize that dynamic Zopesite references * acquisition could make this a painful/impossible question. But counting static references could be very useful. How should COUNT work with say 'standard_html_header? hmmm not sure.. My idea is that at a minimum it could estimate how many references existed below this part of the ZODB tree. CHANGES The idea here is to give a useful indication of objects which have changed. But when and how? I really don;t have an answer to this... - perhaps a limited search using UNDO mechanism - perhaps a simple user ID and date which showed the last person to change it. PROPERTY This one should be easy.. sort adn display all objects in 'manage' based on common property names and values. For example, have a property called 'status' - values might be 'OK', 'buggy', 'draft', 'approved' etc. Too many properties and to many values would detract from usefulness probably, some some pragmatic workflow-oriented values could be very valuable for ordering and developing Zope projects. DISPLAY The idea her is to offer a simple visual toggle HIDE/SHOW like Photoshop, Fireworks, Illustrator and myriad other graphics apps do. Suppose you have a big list of objects in a folder which you do not want to look at al the time. They take up too much screen space, can be confusing and may not be relevant for certain users and roles. Simple selection would be a checkbox, but advanced DISPLAY could be based on the other criteria listed here. For example only show me the objects modified since last week by USER 'really nice client' :-) How easy hard is the above to do? Has it already bee done? What techniques/components exists already to make it happen? What need to be developed? How does this affect Zope core? What woudl you like to see when you click on manage? What would you lceints liek to see? - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']

Multiple servers on Zope?
by Etienne Labuschagne 09 Jan '01

09 Jan '01

Hi there How can I create "multiple" web servers on Zope as in IIS? We have a few domains that resolve to the same IP address. When a user accesses eg. www.geospace.co.za they must get to a different site than when they access www.triangletyre.co.za even though both addresses resolve to the same IP address. In IIS you just create a new virtual web site that "responds" to the new domain name. I am not using Zope through IIS and would actually like to get rid of IIS altogether. Any help to a Zope newbie would be GREATLY appreciated! Etienne Tel: (012) 348 4586 Cel: 082 442 8981 Fax: (012) 361 8355

Learning ZOPE - a useful guide
by Lloyd Kvam 09 Jan '01

09 Jan '01

I have been struggling to figure out Zope. It is a complicated product and it is very hard to know where to begin. This link provides a general guide as how to proceed. What should you learn first? What comes next? While I am sure there is more than one way to answer those questions, this guide does a terrific job. A Developer's Guide to Learning Zope Howto v1.0.2 http://itamarst.org/learningzope/index.html I would recommend adding it to the zopeNewbies listings. -- Lloyd Kvam Venix Corp. 1 Court Street, Suite 378 Lebanon, NH 03766-1358 voice: 603-443-6155 fax: 801-459-9582

MySQL connection woes
by paul_s_johnson＠urscorp.com 09 Jan '01

09 Jan '01

After following several howtos, tracking numerous threads from this list, and spending several days losing my mind, I sense that I am finally getting closer to having Zope and MySQL talking to each other. SETUP: I am running on Linux with Redhat with MySQL 3.22.32 and ZMySQLDA with ZMySQL-python. The later two are installed such that ZMySQLDA is NOT broken. I installed using the RPMs supplied by Ron Bickers available on his FTP site (thanks, Ron) and followed additional instructions supplied on earlier threads. PROBLEM: My problem now is I can't find a connection string that works. I understand the connection syntax and tried every possibility. My suspicion is that I am having a permissions problem with MySQL. I found this former list email: >> My suggestion would be to set up mysql to accept a null login (no >> username, no password), create a database in there called "test" and >> connect with the connection string "test@localhost" >thank u, this was the point to my problem. I have tried a nologin mysql and it >worked with database@myhost !!! :) >so i know i have a grant table problem in mysql (no big deal - i hope :) ) QUESTION: Being a relative newbie to this whole thing (Linux, Zope, MySQL, etc.), how do I create a null login in MySQL with blanket privleges? Could it still be a faulty ZMySQLDA setup? How do I troubleshoot that possibility? Thanks, P. Johnson

ZSQL database connection (ZPoPy) not giving expected results
by Mark N. Gibson 09 Jan '01

09 Jan '01

Ok, here's the situation. I create a folderish object. I insert some info into the postgresql database related to this folderish object. I create a ZPopy database connection within this folderish object. All of this is done through a python method. If I do a query using this new database connection, select for rows I just inserted. The query comes back with no results. I can do this query using another ZSQL DB connection, and on the command line, it works fine. Caching is off for the query. Eventually, after 30 seconds to 4 minutes, all queries seem to work fine. This behavior is inconsistent, sometimes the queries work after no wait at all. Any ideas?

Tux & Zope?
by Jonathan 09 Jan '01

09 Jan '01

Hi all, Just one of those things that keeps popping up on my list of 'things I should try': Zope behind the Tux webserver. For those who do not know: Tux is a very fast webserver for Linux because it operates at kernel level. It can pass requests it can't handle to another server, ZServer for example. Any tried it already? Cya Jonathan

RE: [Zope] ZCatalog and 'fuzzy logic'
by sean.upton＠uniontrib.com 09 Jan '01

09 Jan '01

My understanding is that part of the problem is that sorting a dataset based upon regular expression (doesn't matter what algorithm you use) creates a rather large tree of possibilities that is largely impractical to sort, at least not without a lot of overhead. My compromise for the searches that I'm planning on using is to allow regex searches of "search results" from the catalog. This requires a bit more patience, as it is an unindexed search...
