December 2000 - Zope

Link counter
by Brendon Grunewald 05 Dec '00

05 Dec '00

I have recently been asked by a partner site to provide them with a count of how many times someone links from my site to theirs. Since there are many ways they could hyperlink to that site (Squishdot articles, normal links, banner ads etc), is there a way in zope to keep track or to extract that info? OR am I stuck with the server logs? Regards, Brendon ------------------ 70South: the No.1 source for Antarcticles. For the latest news and views on Antarctica visit : http://www.70south.com

Does 2.2.4 solve Proxy+ZCatalog bugs?
by Marcin Kasperski 05 Dec '00

05 Dec '00

The question as in the title. In changes for 2.2.3 I found: - Resolved known condition in the Catalog where objects are not guaranteed to be unindexed before indexing happens again. Now objects are guaranteed to be unindexed correctly first. This should resolve all outstanding KeyErrors with Catalog, although currently broken Catalogs will require a reindex to resolve them. Has anyone verified whether this in fact corrects the infamous ZCatalog key errors when one tried to reindex site proxied with Apache?

string splitting in dtml

Mike asked: > I have a date string (ie dd/mm/yy) which I'm drawing out of a database > (ODBC connection to Access) with a Z SQL method and I need to use that > data to set the initial condition of a set of 3 select items (ie day, > month and year). Is there a way to split this date (it'll come out > looking like dd/mm/yy) to get the components of it You could use the Python "string slice" syntax, like so: <dtml-let day_of_month="_['start_date'][:2]" month_of_year="_['start_date'][3:5]" year_of_century="_['start_date'][6:8]"> The <dtml-var day_of_month> day,<br> of the <dtml-var month_of_year> month,<br> of the year 20<dtml-var month_of_century><br> </dtml-let> Later, Jerry S.

The only way I see to do this with plain html is to just make 2 forms, the second is served depending on the users input on the first and has hidden input fields. But if you decide to go with javascript, you might as well do the whole logic in one page. See for instance http://www.acenetglobal.com/JSMulti.asp or just enter some of the right words into google, there are a lot of sites about that stuff. cheers, oliver

I'm developping a python simple product. I want to define a tab in the management interface as the manage_main of a subobject in it. Is it possible, and if it is, how can I do that?

HTML - ZOPE?
by Tom Deprez 05 Dec '00

05 Dec '00

Hi, I'm not sure if this is a strictly zope question, but I hope some people can give me an idea on how to solve this problem. I'm creating a form which has amonng it's input tags 2 comboboxes. Now, the content of one combobox, depends on the selection of the first combobox. How can I handle this in Zope, Html? Is this even possible in html? I assume, yes if you refresh the page each time the user makes a selection in the first combobox, but how? Thanks, Tom.

On DTML and Python Script
by Phill Hugo 05 Dec '00

05 Dec '00

Jason Leach pointed out that Document Template could include ASP/PHP style Python escapes to embed code. This may seem a good idea at first but part of the really nice thing about Zope is that it goes a fair way to ensure you organise your work cleanly and seperate logic from the layout. In PHP I always use FastTemplate which offers pretty much only what <dtml-var VARIABLE_NAME> does (that doesn't include <dtml-var "VAR1+VAR2"> or anything "clever"). The benefit of having no logic in your HTML is huge when you have multiple people working on the project. The "creep" of template systems to hold more and more logic such as Loops, Conditions etc is forgivable as it allows basic programming to be done by the HTML people but strictly it isn't necessary as long a variable insertion / tag replacement is possible. If you are "having to [use] all those dtml tags" then you're probably at the point where replacing that big chunk with <dtml-var welcomeMessage> is in order. This could be anything you want (Python method, External Method, DTML method etc) which does the real logic and conditionally returns its output to the master template (that content possibly from another smaller, reused DTML method - it amazing how many sites use the same text all over it (like Next 10, Prev 10 for example!). At that point you've removed any fear of the HTML people walking over your code with a bulldozer and it means they can update things while you do. What I'm suggesting is that <%, <?php and <%py are Bad Things. If you want them, use ASP with Python hosted inside or PHP. Much of the benefit of Zope is that it keeps things elegant. The overhead of splitting things up so much is small when you start to reuse the bits (by my milage this is on regular occasion). Even the <dtml-if>, <dtml-in> and <dtml-let> tags could be argued to be Bad Things but they are convenient in some cases (they are easy for HTML writers to understand and can be used for simple things by them). I don't really see the "convenience" of a Python code escape as its just as easy to make a Python Method and pop <dtml-var MyPythonMethod> in its place keeping things neat. Still, I suppose it'd hardly matter if it was available, those who agree with the above would probably ignore it, much as I ignore it in PHP and use FastTemplate instead. Phill

I use Progress WebSpeed at work. Webspeed does something similar to what you suggest, only with Progress 4GL embedded in the HTML between certain tags. This is OK at first, but it often gets ugly, especially where you are jumping in and out of 4GL just to do simple conditionals or iterations that DTML makes not too painful with <dtml-if> and <dtml-in>. OK, I am one of those poor fools who is trying to do too much in DTML. But it's not too bad as long as you factor it out well and keep any messy code in DTML methods rather than mixed in with your HTML. Just my opinion, though.

Running Zope
by Norm LaDuke 05 Dec '00

05 Dec '00

Can anyone out there tell me why anyone would use a product whose tutorial won't even run. You guys are either INFINITELY more patient than I or you all have WAY too much time on your hands. I'm about 7 hours into this thing and we do finally have zope up and running but of course the tutorial doesn't work. Requires you to put in an ID then blows up and goes no further. What a piece of garbage!!!! (Does my frustration show??)
