Product Creation and Permission
by Jason Joy 03 May '01

03 May '01

I started working on this the other day and posted some questions regarding this, and I apologize ahead of time for the length of this message, but this has me absolutely baffled and if anyone can offer some insight into Zope's ObjectManger and how it works in regards to this, it would be extremely appreciated. I am constructing a product that is basically in essence a SQL-Zclass, where you can manipulate SQL in a Object Manager. I have two classes, A and B, where B works off of A. So, after you create a instance of A in Zope (in a folder or such), it appears .. and then you click on it, it brings up a management screen (assuming that we're allowable to do such) that runs a SQL command that displays the results as "objects" in the instance of A. These instances displayed in A are related to B. Clicking on one of these new instances of B should bring up a list of further related objects contained in B (in the SQL database) and allow you to manage objects C, D, E... etc. The problem that I am getting is A works fine, and shows the objects of B contained within. However, when I click on one of these in the management screen, I get a request to login again, and I can never enter in a correct authentication despite having full privledges to this Zope server, and after three tries, I am dropped to a Unauthorized screen saying that Username and Password are not correct. Can anyone shed any light on this issue? Is there something I am missing, some class that I am not inheriting that's allowing Zope access to it's authentication methods? Or is what I am doing just plain impossible in Zope? I have included examples of what I am trying to do below and apologize for the length of this message.

I think this has been addressed with more recent ZCatalog versions. However, there is probably some conversion step necessary.

Summarization and Zope
by Ausum 03 May '01

03 May '01

After searching the Zope's site and the web, this is a question I've come up with: Is anybody working on a Summarization product for Zope? Some weeks ago, after reading the Directions Road Map, I realized that the best way to include these kind of features in Zope was to write communication components to existing software, rather than dealing with new, complicated code, from scratch. But I'm assuming there aren't current projects on summarization written in Python, so if this is correct, this may be the right moment to start a new proposal on this subject, at least at a very basic level. Regards, Ausum

Re: [Zope] [ANN] zshell: The Zope Shell
by dave＠kovach.com 03 May '01

The shell idea is neat... Better at times than using the manage interface. Though it is pretty quick at what it does in terms of its ease of use for the admin... Has there been any work on a rich-gui editor and one that is more integrated with a HTML/XML/XHTML editor outside of just using WEBDAV with Dreamweaver or something. Something where its almost like your in the same IDE to do everything - build objects in Zope, edit web content, build html files etc.??? Cool work though.

Re: [Zope] [FEATURE REQUEST] Improving Zope's management interface

Hey Ausum, Very cool! Improvements indeed! I don't care for the splitting of words into separate links "click vi/click ew" but everything else seems like a thoughtful fine-tuning of the UI. Hopefully these ideas will make it into an future release. Cheers Lee >From: Ausum <augusto(a)artlover.com> >I've uploaded pic snapshots hoping to explain them.

RE: [Zope] TUX and Zope? + ab results
by sean.upton＠uniontrib.com 03 May '01

03 May '01

Caching w/ TUX, AFAIK, isn't going to be as efficient as Squid. I think that likely the reason is that TUX is a webserver and not a cache, and that (if TUX can cache; I think it can just proxy!) the overhead to proxying likely mitigates a lot of the magic marshmallows in TUX like Zero Copy, checksum caching, etc - a network copy is going to add latency, and cache machinery is going to eat some CPU cycles. Somebody correct me if I am mistaken here. Tux might work well with ExtImage/ExtFile and TUX's machinery for serving some URLs and passing on others to another server (Apache, ZServer...). For predictable content, that is served over and over, seems like Squid in http accelerator mode is a better solution...

TUX is a linux only thing ATM, so any integration of the two would have to be some sort of add on to a vanila zope. > TUX 2898.55 Requests per second > AOLserver 603.14 Requests per second > Apache 502.51 Requests per second > Zope 60.57 Requests per second There are important reasons why the figures are so different. In the case of TUX, the kernel server tries to do as little work as possible to translate a request into data flying out the NIC. Zope, on the other hand, at the very least checks to see if the requester has permisson to access that object, and often looks after other things like acquisition, setting caching headers and obviously executing content generating code. The easiest way for Zope to take advantage of TUX would be to have a TUX based caching reverse proxy sit in front of the Zope server. All of the images and other static content window dressing for the site which will always be served up to everybody can have cache TTLs set so they quickly end up in the proxy, which can serve them up as fast as they can go. If you still want to crank more speed out of zope, the next thing to do would be to profile the steps needed to serve up requests for static content where having a permission system matters, and look into optimizing that.

Catalog Anything Problem
by Bobby Mathew 03 May '01

03 May '01

Hi all I used the catalog anything manual to do have my sql data from postgres to be indexed into zope but i ran into trouble. I must warn you i am a newbie so it must be a very silly mistake somewhere. Let me explain what I did My config Linux OS Zope 2.3.0 Postgres 7.0.3 ZPyGreSQL DA The process Since i am a newbie i was not sure what you meant in the cataloganything doc when you said... ============= Setting Up the Catalog The first step in any search is to set up the catalog. There is no difference in setting up a catalog for "normal" searches and setting one up for a search of SQL data, so I'm not going to go into detail here on how to do that. Just make sure you have created a catalog with the desired indexes and meta data. ============== So i just used the chapter 9 reference that was provided earlier and i created a ZCatalog called Products. I was not sure what else to do so i just let the defaults remain as it is - the AnimalTracker example in chap 9 didnt seem relevant to me since i have no dtml methods to search for - only products info from the postgres. So i just didnt do anything further. I have a products table in the postgres rdbms that i want to search by title and description. So after this i created a zsql method called getProdtoCatalog under the ZCatalog itself - the query i used is SELECT prodid as Number, Title, Descr || ' ' || Title as PrincipiaSearchSource, 'Product' as meta_type, prodid as id, Descr as summary FROM products Now i went into the Find Objects section and searched for the getProdtoCatalog zsql method and added to the catalog Next i went and created the python script (again under the Products ZCatalog itself) and i called it catalogProducts this is the code inside for book in container.getProdToCatalog(): container.catalog_object(Product, '/learn/search/Products/'+Product.Number+'/proddetails.html') print 'Product #' + Product.Number return printed The moment i test it i run into trouble - Can any one help please regards bobby For the error message this is what i get.... =================== Zope Error Zope has encountered an error while publishing this resource.
