ZSQMethods shipped with a Product
by Gilles Lenfant 26 Nov '03

26 Nov '03

Hi, Is there a way to do FS based ZSQL methods in a Product ? Actually, my product (under development) uses direct MySQLdb.connections created/deleted for each method. This works but... 1/ It's not easy to be DBMS engine independant that way. 2/ Creating new DB connector for each Web transaction slows down the stuff. Thanks in advance -- Gilles

some Zope issues: dtml-zpt, permissions, scalability
by Andre Meyer 26 Nov '03

26 Nov '03

Dear Zopers During the last few weeks I have been working through the documentation of Zope for building my own products. One valuable source was the Zope Bible. With help from this list and the authors of the book I decided to go for a file system based product using ZPT. Unfortunately, the example in the book is using DTML like most others still do. When trying to convert from DTML to ZPT I found the following problem: It is easy to change dtml-in to tal:repeat and the like. But how to convert from dtml-call to tal? Look at the folowing snippet: -------------------------------------------------------------------------------- <dtml-unless SelectedGroup> <dtml-call "REQUEST.set('SelectedGroup', 'All')"> </dtml-unless> <dtml-unless start> <dtml-call "REQUEST.set('start', 1)"> </dtml-unless> <dtml-unless sort_by> <dtml-call "REQUEST.set('sort_by', 'LastName,FirstName,MiddleInitial')"> </dtml-unless> -------------------------------------------------------------------------------- Another problem occurs with permissions. The following snippet works in dtml, but when converted to zpt (accessing here/listEntriesByGroup) the same method cannot be accessed any longer. -------------------------------------------------------------------------------- <dtml-in "listEntriesByGroup(_['SelectedGroup'])" size=20 start=start sort_expr="sort_by"> <tr <dtml-if sequence-even>bgcolor="#CCCCCC"</dtml-if>> <td><input type=checkbox name="EntryIDs:list" value="&dtml-id;"></td> <td><a href="&dtml-id;"><dtml-var title></td> <td><dtml-var Title> </td> <td><dtml-var Company> </td> <td><a href="<dtml-var id>/editEntryForm">Edit</a></td> </tr> </dtml-in> -------------------------------------------------------------------------------- Yet another issue is related to scalability when I have an object that references a list of other objects using a dictionary. How does this perform when the dictionary contains 10.000 or 50.000 entries? Is that feasible or are there better solutions? thanks a lot for your help Andre

DTML conversion to TAL
by Kevin Rosso 26 Nov '03

26 Nov '03

I am new to ZPTs, but recently have becomed involved with them. I am familiar with DTML and want to make similar functionality using "TAL". In the past , my group has made use of the <dtml-var> method to call strings from a folder to be used in image links, hyperlinks, etc. The main reason we use this <dtml-var> is because we have sites running in a development environment that are then moved to production. To make this move seamless, we create variables in the "properties" tab at the site root. For example, the variable string we create in the "properties" tab in the ZMI may have a value of: /devsiteFolder/images/ and be called, "imageDir". This variable is then used to call an image throughout the site using <img src="/<dtml-var imageDir>/imageName.gif"> When the site is moved to production, we change the string /devsiteFolder/images/ to /productionsiteFolder/images. Very simple, yet I cannot find good documentation on how to convert this to TAL if I wanted to use this inside a Page Template...Please Help I have read and re-read the current documentation and articles relating to "DTMLers learning TAL" and I must say the syntax is what has me most confused. A simple chart with sample TALES and its common functions would be a great help. Thank you, Ryan --

[OT] vetomail sucks
by Paul Winkler 26 Nov '03

<rant> Is everyone else getting an autoreply from DLANCE(a)kc.rr.com every time they post to the zope list? He/she is using some anti-spam service called "vetomail". Does anyone find this as obnoxious as I do? Has anyone succeeded in contacting dlance to request it turned off? Does anyone else think this "service" might be grounds for removal from the mailing list? </rant> -- Paul Winkler http://www.slinkp.com Look! Up in the sky! It's ULTRA GANGSTER OF THE FUTURE!

Advice Needed.
by Goldthwaite, Joe 26 Nov '03

26 Nov '03

Hi, Sorry to bother everyone again. I try to keep my questions to a minimum but there's just too much to Zope and Python and I'm feeling a bit overwhelmed. I also apologize for not being more specific with my questions but just I don't know enough to be more specific. The thing I'm trying to do is conceptually very simple but I can't seem to get all the pieces together. I'm trying to create an Executive Information System that puts my client's financial information online with drill down capability. I'd basically like to be able to have Zope accept a URL something like this; http:\\MyZopeServer\IncomeStatement?rgn=80 and have it generate an Income Statement routine for region 80. They have a hierarchical structure with groups, divisions, regions, areas, sales reps, etc. so the code "rgn" might be "grp" or "area". That sounds pretty simple doesn't it? I can't seem to put the pieces together. I was able to write a python module that takes the organization type and number and writes an Income Statement to a file in HTML. I got the project from The Book of Zope working but all the forms seem to be linked to DTML files. It didn't give me any examples on where to get the URL parameters from or how to just return my finished HTML to Zope. I also went through the Template Attribute Language section of The Zope Book and have kind of an understanding on how TAL templates work but I don't see where they get URL parameters from. Having been a programmer for 20 years, I'm most comfortable with programming languages like Python than with TAL or DTML. Ideally, I'd like the above URL to execute my Income Statement function and pass the org type and number. My module could then return the HTML page. The main problem I see with this approach (other than the fact that I can't figure out how to do it) is that I need to connect to the database every time. Also, the Income Statement module returns data appropriate to the SQL user name so I need to have some way to associate a Zope user with an SQL database user. I work at a Microsoft shop and am getting a log of pressure to go with IIS and .Net. There are a number of people here that have already done some similar work in the sales area. I'm in kind of a race to get something put together so I can demo it. That makes it hard because I tend to jump around a lot just trying to get things working without knowing the best approach to take. I guess that's why I've got so many pieces but no pie. So, what's the best approach to take? Should I try to do it with Page Templates and python scripts? Is that efficient? Is the product approach better? Whichever approach is best, I have a ton of questions. Too many to ask for free. I can pay for a few hours of help if anyone is available. I guess what I'd really like is a product that would translate the above URL into a call to a Python function passing in the user info, the database connection, the organization type and number. It doesn't seem like that would be too hard for someone who knows what they're doing. So far, I haven't had much success. Thanks Joe Goldthwaite

RE: [Zope] Advice Needed.
by Wilson, Derek 26 Nov '03

I'd suggest using ZSQL statements with a MSSQL DA product. You can set the statements to require variables such as region, username, etc, which then can get passed in the SQL. I've had great success converting Seagate Crystal Reports pages to ZSQL and ZPT pages. You just copy the SQL to a ZSQL method, and use the ZPT to handle presentation.
