More REQUEST.set not incrementing SUCCESS!
by Jerry.Spicklemire＠IFLYATA.COM 12 Jan '00

12 Jan '00

Jeff Hoffman suggested the following code, that's quite a bit cleaner than what I came up with, and it also works quite well. <dtml-call "REQUEST.set('z_t', _.string.split(_.str(ZopeTime()))[0])"> <dtml-call "REQUEST.set('u_all', 0)"> <dtml-call "REQUEST.set('u_logged', 0)"> <dtml-call "REQUEST.set('u_today', 0)"> <dtml-call "REQUEST.set('u_not', 0)"> <dtml-var u_all> <dtml-var u_logged> <dtml-var u_today><br> <dtml-in count_users_logged> <dtml-call "REQUEST.set('u_all', u_all + 1)"> <dtml-if logged_on> <dtml-call "REQUEST.set('u_logged', u_logged + 1)"> <dtml-if "_['z_t']==_.string.split(_.str(_.DateTime(logged_on)))[0]"> <dtml-call "REQUEST.set('u_today', u_today + 1)"> </dtml-if> <dtml-else> <dtml-call "REQUEST.set('u_not', u_not + 1)"> </dtml-if> </dtml-in> I'm a bit mystified that the only detectable difference between this version and *many* that I tried without success looks to be the spaces between objects and keywords in expressions, along with the complete absence of <dtml-let>. e.g <dtml-call "REQUEST.set('u_logged', u_logged + 1)"> vs. <dtml-call "REQUEST.set('u_logged',u_logged+1)"> I've looked at lot's of code samples that have no spaces, and have seen enough error messages to think very hard about random spaces in expressions. This is a good example of how code lore (superstition) gets proliferated, but it's hard to argue with working examples. Thanks again, to Jeff, Jim, Pavlos, et. al. Jerry S.

Some installation knowledge, apache integration knowledge (rewrite rules, mostly) and system resource managment. No more so than any other type of long running process. Their objection would probably be more aesthetic than anything else, ie, Zope is 'alien' to them, especialy if they specialized in some other form of dynamic content like PHP. -Michel

Simple Acquisition Question
by James W. Howe 12 Jan '00

12 Jan '00

I have a newbie question concerning acquisition. I was playing around the other day trying to build a simple web site. I was taking some existing web pages and refactoring them into what I thought might be reusable bits and pieces. I ended up with a structure something like this: / Pages <... DTML methods to generate complete pages ...> Parts <... DTML methods containing page parts ...> I built my page parts first and viewed them to make sure they looked ok. I then attempted to build a page. I started to assemble the pieces when I ran into a couple of problems. My first problem was figuring out how to access my "Parts". First I tried something like: <dtml-var Parts/partName> but that didn't work. After doing a little more reading, I came to the conclusion that I needed to do something like: <dtml-with Parts><dtml-var partName></dtml-with> This sort of worked. The problem is that some of my parts are designed to pick up information from the component which is containing it. For example, one part might have code like this: <dtml-var contents> I defined a default DTMLMethod called contents at the Root level, but I want to be able to redefine it at a lower level. For example, a DTMLMethod contained in the Pages folder needs to define its own implementation of contents. I was hoping that I could reference my generic part from Parts but have the part acquire the "contents" from the page which was utilizing the part. However, my part always displayed the contents from the root level. I'm thinking that this is because when I use dtml-with to access the part, the part will get namespaces which include itself and its parent folders, but will not contain the namespace of the caller (or the namespace appears earlier in the namespace list). Is this mostly correct? Is there a way to accomplish what I want to do, namely access a DTMLMethod in some other portion of the tree but have the accessed method resolve its variables in the callers namespace? Finally, does the fact that I'm facing this problem indicate that I'm just not structuring my data in a very "zopeish" manner, or am I just not knowledgeable about all the ways to use acquisition.

Calling a stored function with the Oracle DA
by Jim Cain 12 Jan '00

12 Jan '00

All, The "begin procedure (x, y, ..); end;" syntax works for procedures okay, but how do I call a function? The typical quick & dirty way in sqlplus is variable x number -- or whatever begin :x := function (a, b, ...); end; This function actually does updating, so I can't use the pragmas to make it acceptable in a select. Thanks, Jim

Re: Anyone using Zope Mail Host with MS Exchange ? (chas)
by David Salgado 12 Jan '00

12 Jan '00

Hi Chas >I have a client reporting that mail sent from Zope >using a MS Exchange box as their Zope Mail Host >never arrives. Just tried using our Exchange server as the SMTP server for a MailHost (which works just fine with the other two 'real' SMTP servers I have access to, and sure enough, the mail never arrived. Looks like a real MS feature -- anyone else? BTW, the Exchange server works OK as an SMTP host from Outlook Express, which is the only 'standards-based' mail client I've got on this machine. ><guess> >Maybe their exchange server is demanding that users authenticate before >sending (this is configured with a checkbox somewhere in the Exchange >Admin labyrinth, iirc). I don't know why this would cause a noticeable >exception tho... ></guess> Don't think so, because I'm not authenticating when I use Outlook Express to send SMTP mail via the Exchange server -- I am on the same network though, but then so is Chas's client's machine. Cheers David

Re: special user can't add ZClass
by Jan Stohner 12 Jan '00

Hello, > The question: > We have created a role called 'NewsPoster' that should be able to post > news articles for publication and basically have no other privileges. I'm > having a terrible time trying to tweak the permissions so this person can > log in, let alone post articles. What should be checked on the security > page? Obviously the person needs 'Add News Articles' (our ZClass), but > anything else beyone what 'Anonymous' has? I had a similar problem the week before, when i wanted to grant the right to create class instances to a role. The Permission "Add Link" (Link is the Name of the Class) wasn't enough. Even if i assigned ALL permissions that the "Manager" role has to the user role, it didn't work. The only way that worked for me was to assign the "local rule" of "Manager" to the user role. So you should create a Folder which will contain all News Articles and in the Folder permission tab, click on "local roles" an assign the "Manager" role to your user account. One question remains for me: What is the reason for a "Add Instance" permission, if it doesn't work for my Products? The "Add Documents,.." permission works, but permissions for my product not. Is there something wrong with my products, my understanding of Zope security or with Zope? (I assume not with Zope, but what did i get wrong?) Jan -- Dipl.-Inform.

Passing a variable def back to the current page and argument passing argument passing
by J C Lawrence 12 Jan '00

12 Jan '00

A couple questions: 1) Under Zope, how do I get the parth to the current method/document, or in PHP terms, is there an equivalent to $PHP_SELF? eg I have a DTML method: http://.../Folder/method And I want that method to internally generate HTML ala: <a href="method?variable=XYZ"> How do I get the URL path to the current invoking method so I can construct the appropriate HREF? How do I do it if the method is called by another method (possibly several removed) ala Method1 calls method2 calls method3 which generates the HREF? 2) I have a DTML method that is generating a page from an SQL database. This is working fine. However what I want is for various links and fields on that page to invoke that same DTML method again except with different variable values. I am expecting that I can do this CGI-style as above with "?variable1=XYZ&variable2=QRS" on the URL (see the Q above). Is this true? Is there a way that I can pass values from the URL to a DTML method in a more intuitive fashion, say if the DTML method is under: http://.../folder/method Can I call it as so: http://.../folder/method/XYZ or http://.../folder/method/XYZ/QRS and have XYZ and QRS passed appropriately as arguments/variables to the DTML method much in the manner that your category path is passed in the URL for Yahoo? eg: http://dir.yahoo.com/Reference/Dictionaries/English/ -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--
