[FAQTS] ZOPE Knowledge Base Update -- July 30th, 2000

30 Jul '00

Hi Guys, The latest entries to be entered into http://zope.faqts.com regards, Fiona Czuczman Including: - Benchmarking between Zope and Tomcat - How can I get the Zope tutorial to work? - Is there an easy way to simulate the functionality of a while loop in DTML? - What is the best method to enter more attributes about DTML Document? - How is it possible to create "show DTML-Source"-link like on some sites on zope.org? - Is there an easy way to increment the month or year of the DateTime object? ## New Entries ################################################# ------------------------------------------------------------- Benchmarking between Zope and Tomcat http://www.faqts.com/knowledge-base/view.phtml/aid/5062 ------------------------------------------------------------- Fiona Czuczman J. Atwood Benchmarking between Zope and Tomcat http://www.zope.org/Members/BwanaZulia/zope_benchmarks/tomcat1.html (1 of 4 rounds) ------------------------------------------------------------- How can I get the Zope tutorial to work? http://www.faqts.com/knowledge-base/view.phtml/aid/5063 ------------------------------------------------------------- Fiona Czuczman Amos Latteier Here's what to do: * Get Zope 2.2, download it, install it. * Log in to Zope with the super user account. * Create a manager account by going to the User Folder and adding a new user, and giving them the Manager role. * Quit your browser to log out. * Log into Zope as the manager you just created. * Create a Zope Tutorial, by adding it from the product add list. * Now do the tutorial. ------------------------------------------------------------- Is there an easy way to simulate the functionality of a while loop in DTML? http://www.faqts.com/knowledge-base/view.phtml/aid/5065 ------------------------------------------------------------- Fiona Czuczman Patrick Lewis This is real ugly, but you asked (untested, but you get the idea): <dtml-try> <dtml-in "_.range(1000)"> <dtml-if whileCondition>   <dtml-else> <dtml-raise type="conditionFalse">errormsg</dtml-raise> </dtml-if> </dtml-in> <dtml-except conditionFalse>  <dtml-else> <dtml-raise type="RangeError">Oops! Exception never raised.</dtml-raise> </dtml-try> This only works if the loop will cycle less than 1000 times. Needless to say, this is done a lot easier in Python. ------------------------------------------------------------- What is the best method to enter more attributes about DTML Document? http://www.faqts.com/knowledge-base/view.phtml/aid/5098 ------------------------------------------------------------- Fiona Czuczman Chris McDonough Problem: Short and probably obvious problem: what can I do to be asked for more properties while creating DTML Document (say I wanna be asked about description and keywords which I use in meta tags)? Solution: There's not a particularly obvious solution other than to define a ZClass which inherits from DTML Document and exposes a constructor form that asks for these properties as well as an edit form that does same. See the ZClass tutorial on Zope.org at http://www.zope.org/Documentation/Guides/ZDG-HTML/ZDG.html to get started. ------------------------------------------------------------- How is it possible to create "show DTML-Source"-link like on some sites on zope.org? http://www.faqts.com/knowledge-base/view.phtml/aid/5099 ------------------------------------------------------------- Fiona Czuczman Chris Withers Put a link as follows on your page: <a href="view_source">show DTML-Source</a> Then create a dtml method called view_source. What do you put in it? Well, see the following: http://www.zope.org/view_source/view_source ------------------------------------------------------------- Is there an easy way to increment the month or year of the DateTime object? http://www.faqts.com/knowledge-base/view.phtml/aid/5100 ------------------------------------------------------------- Fiona Czuczman Jim Sanford Problem: Adding a numeric value increments the day. Incrementing the year is easily doable, but incrementing the month is significantly more difficult. So I'm just curious if there's a function that will actualy modify the parts of a DateTime object, or something way that I'm not thinking of to easily increment the month. Solution: <dtml-var "_.DateTime(_.str(ZopeTime().month()+1)+'/'+_.str(ZopeTime() .day())+'/'+_.str(ZopeTime().year()))"> will give you a datetime object one month in the future ## Edited Entries ############################################## ------------------------------------------------------------- Is there a way I can grab the time value on my current system that Zope is running on with a MILLISECOND precision? http://www.faqts.com/knowledge-base/view.phtml/aid/4964 ------------------------------------------------------------- Fiona Czuczman Shane Hathaway Works on 2.2.0: <dtml-var expr="_.DateTime().millis()">

Evaluate Zope for New App
by G. Alan Tucker 29 Jul '00

29 Jul '00

Hi, I am in the process of evaluating the best architecture for a new Internet-based service that we are going to offer to the Japanese market. I would like to evaluate Zope, and I want your opinions on whether Zope as a solution is adequate, competitive, or the best one available. >From my perspective, I am a firm believer that Python is a great language, and very efficient to build and maintain, and that Zope will also enjoy a bright future. But they are not as widely accepted as Java servlets / JSP / EJB on the web server backend. So I may have to work to convince the CEO that we should go against the industry on this matter, and any information you could provide would be helpful. One important point is that the interface will be all in Japanese. Please confirm that Zope can handle Unicode and / or other 2-byte character sets. The application will be designed for a financial industry to handle transactions between independent agents and their providers. The agents will get multiple quotations from multiple providers, while entering the customer data only once into our service. The functionality looks something like this. 1. The agent inputs about 100 pieces of data for the customer into our system. The exact data will vary, depending on specific product. We will store this information into our database. 2. The agent will choose several providers from a list. 3. The system will (mostly likely) use XML to send the customer data to the chosen providers. The providers will return to us pricing and some description of the product. 4. We will aggregate the quotations and present this to the agent. The agent will choose a few of the quotations to present to the customer. The agent will refresh the view, and print it for the customer. 5. If the customer chooses one of the products, the agent will enter the order to the system. Since the customer data is already there, we only need to pass a short XML message to the provider. 6. Our system will also have to track some information like which agents can use which providers, as well as commission rates. 7. We will also provide some sales automation functionality to the agents, but the exact details depends on the segment of the agent market we go after. Some examples might include calculating commission rates, querying customer birthdays to remind the agent to send them a card, etc. In general our server will not provide that much processing of the customer data, either during or after the transaction. Mostly we are saving it and passing it between the agents and the providers. However this data does need to be encrypted over SSL. I think we could do the SSL encryption on an edge device, but I would be curious to find out how others have handled this with Zope. I would like the list to help me with the following. - How suitable is Zope for this type of application? - What is a common back-end data storage for Zope in this type of application. - We need scaleability and redundancy. How suitable is Zope for this? - Any other comments or questions. Best regards - g -- These || G. Alan Tucker || Failure is not an option. . .

Interbase DA compiled for Windows?
by R. Herold 29 Jul '00

29 Jul '00

Hello, because of persisting problems I experienced in trying to compile the two modules that connect to Interbase (kinterbasdb-0.2.1.tar.gz and InterbaseStorage098.tgz), I turn to the list: Have you succeeded? Could someone kindly provide the required files (i.e., *.pyd-files)? From the former product, I managed to generate dbi.pyd (gcc-2.95.2-mingw32), but not kinterbasdb.pyd, which gave many errors related to missing references. Sure, turning to linux would easily solve this problem, but the present setting requires Zope on an intranet NT machine.

Hi there, I´m still looking for a solution to save files via WebDAV to Zope using FronPage 2000. Zope has probs with these _vti_xxxx folders which are required by FP2000 but can´t created in Zope because of the beginning "_". Any ideas?
