SQL authentication
by Milos Prudek 03 Sep '01

03 Sep '01

I'm trying to implement a SQL-based login. It looks more difficult than I anticipated. Here's what I need: - Zope based web system where anonymous users can register. - Registered users should be able to login using a web form. - A free webmail system using the IMP. IMP is PHP-based, so I guess I must use SQL for my user list in order to share user info among Zope and IMP. LoginManager is unfinished, documentation is too sparse. Also it was last released more than a year ago, so I'm not sure whether it's being developed. GUF has good docs but I have problems implementing it. I'm looking for the easiest solution. Something that is well documented, including examples. -- Milos Prudek

Hi, I need too change the AUTHENTICATED_USER / AUTHENTICATION_PATH with a script (means: without switching to a protected page that raises the classical basic authentication box) Any hint ? Thanks in advance --Gilles

when to opt for a backend DB over ZClasses?
by dedmundson＠bigfoot.com 03 Sep '01

03 Sep '01

I've done a number of smallish Zope sites that make heavy use of ZClasses and ZCatalogs. Now I'm involved with a project where we need to create (and search over) millions of objects. Even though the objects are relatively lightweight (just a few floats and strings), should we be using a backend database rather than ZClasses? This comes up a lot in the archives, but I've never seen a clear exposition of when one should forego the beauty of ZClasses for a more traditional (backend) storage.

RE: ZSQL method and database connection acquisition
by Frederic Quin 03 Sep '01

Hi Jon, I had the same problem as yours. What I did it's adding my two folders at the root folder, naming then like my database names. Then, I added the same Z SQL Methods in the two folders. In that way, I call the Z SQL Methods like this: <dtml-in "DBName_1.SQLMethod_1()">...</dtml-in> Regards, Frederic

RE: [Zope] Good Use for Zope?

Since barcodes are always unique numbers, you are likely to find that you would have good luck using keyboard-based barcode readers and a simple web form. In Zope, you could set up a BTree Folder that contained all your book records as some sort of object; the object id for your books would be the barcode, and you could use ZCatalog to catalog all the info, and enable barcode searches very easily. I imagine you could do this in ZClasses if you wanted a quick and easily solution, and you wouldn't have to mess with using a relational database; the upside to this setup is that all your data would be web-maintainable... Also, I think someone hacked some code to decrypt those lame CueCat barcode scanners to work in Zope; the encrypted text would be input into a text area, and when submitted, they would return the correct barcode...

I'm new to Zope but I'm excited by its possibilities. I'm going to be doing some contract work to setup a database for a high school resource center. The basic idea is that all the materials available for the teachers to checkout (book sets, vidoes, math materiels, etc.) would be on the database and would be set up with a barcode system and wand for quick checkout, much like any lending library. The nice part is that every teacher is already connected on an ethernet lan, so I want to set it up so that they can search the database from their classrooms without having to trudge across the campus only to find out that what they were looking for isn't in the system or has been checked out. The first ideas of the school personnel were filemaker or access. I definitely am not doing access. The point is, has anyone done a barcode checkout system on zope? Good idea? leland myrick _______________________________________________ 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 )

Solution to force authentication (was: getting index_html instead of manage_main in some browsers)
by Dominique.Dutoit＠cec.eu.int 03 Sep '01

03 Sep '01

Some browsers (OmniWeb, iCab) don't preemptively send the authorization header and so they are authenticated as an anonymous user in the ZMI. The result is that the ZMI frames are displayed but the file manager is not. But I've found a way in Zope 2.4 to ask the browser to send the authorization header. Just edit line 139 of App/Management.py from manage_workspace__roles__=('Anonymous',) to manage_workspace__roles__=('Authenticated',). I don't know if there's any issue by changing this line...

How to search a whole sub-tree?
by aaa＠simplesky.com 02 Sep '01

02 Sep '01

Hi Zopers, I'm a newbie in this great zope world, and I've got a question that I'm sure is trivial: Situation: I have some folders that make up a catalog, and inside these folder there are other sub-folders and products. Problem: How can I find the products that match a particular criteria (eg. price<1000)? I know about ZCatalog, but do I have to refresh the index every time I change a price? Or do I have to traverse the whole catalog tree (deep first search, or similar algorithms)? I really hope there's a better way to do that. I'm still stuck in the relational database kind of thinking, this OO database is new to me. But "select * from prod where price<1000" would be nice. Nothing that easy with zope? Thanks in advance |G|

how to upload a batch of files????
by Robert Rottermann 02 Sep '01

02 Sep '01

Hi there, I would like to be able to upload a batch of files to Zope. What I have in mind is something like having a textbox where I list the files to be uploaded from where some magical function reads the names and does the upload. Is this feasible or have I to stick with a single file per action approach?? thanks for your ideas Robert www.redcor.ch don't mind my typhos I see them neither
