generalizing DTML method question
by Jean Jordaan 23 Aug '00

23 Aug '00

Hi Zopers How do I generalize this DTML method? ....................................... <dtml-call "REQUEST.set('myList', [])"> <dtml-in origin_values> <dtml-call "myList.append(name)"> </dtml-in> <dtml-return myList> ....................................... The problem is that 'origin_values' bit. It's a TinyTable. I want to make 'makeList' a DTML method on its own, and then call it to make lists of: clearance_values docs_values origin_values products_values series_values -- jean

conclusion (sort of) > > > I suggest that you: > > > > > > 1) Monitor your Zope clients' thread usages by using their debug > > > facilities. did this and saw that a lot of connections spent on getting images. when the images were moved so that apache serve them, the server is more responsive, now, i seldom encounter more than 100 simultaneous httpd connection. it's as if zope is responding slowly that connections to apache accumulate. all the images are small in size (<20k). i still don't have the answers to why that will affect response time. anybody? and i'm sure i never did any other changes to the setup. only moving images to apache. thanks -------------------------------------------------------

Indirect method lookup? (Update)
by Jeff Hoffman 23 Aug '00

23 Aug '00

Ok, knowing more about what's going on, now, I figured I would send an update to the list and hope it jars someone's memory. Here's what I am trying to do: I have a ZClass, MyTestClass. MyTestClass has two methods: method1, and method2. There are two other methods, showMethods and showMethods2, but they are only needed for the purpose of demonstration. I created an instance of MyTestClass with an id of 'test'. showMethods (a DTMLMethod) is defined as: <dtml-var standard_html_header> method1 = <dtml-var "_.hasattr(this(), 'method1')"> method2 = <dtml-var "_.hasattr(this(), 'method2')"> nullmethod = <dtml-var "_.hasattr(this(), 'nullmethod')"> <dtml-var standard_html_footer> and, when invoked on my 'test' instance, returns: method1 = 1 method2 = 1 nullmethod = 0 We're cookin'. Now, I need to get the same results with a PythonMethod. showMethods2 (a PythonMethod) is defined as: print _.hasattr(self, 'method1') print _.hasattr(self, 'method2') print _.hasattr(self, 'nullmethod') return printed which, when invoked on my 'test' instance, returns: 0 0 0 I have tried every permutation of Python code I can, and none work as the DTML Method does. Somebody? Anybody? :-) --Jeff --- Jeff K. Hoffman 704.849.0731 x108 Chief Technology Officer mailto:jeff.hoffman@goingv.com Going Virtual, L.L.C. http://www.goingv.com/

processing dtml in external method
by Scott Shepherd 23 Aug '00

23 Aug '00

Friends, I have an external method that returns a string containing dtml, but I want it to evaluate the dtml and return the result. How do I do that? I noticed in, say, /usr/share/zope/lib/python/Products/ExternalMethod/ExternalMethod.py, that dtml-containing *files* are used as object methods like this: from Globals import HTMLFile manage_main = HTMLFile( 'methodEdit', globals() ) so I figured I could do a similar thing with a dtml-containing string and an external method: from Globals import HTML dtml_string = '<dtml-let x="it works"><dtml-var x></dtml-let>' external_method = HTML( dtml_string, globals() ) This in fact works, but if I try to reference anything in the current object, like dtml_string = '<dtml-var id>' I get KeyError: id. Apparently I'm getting dtml evaluation but not in the context of the current object. What am I doing wrong, and (for extra credit) why doesn't ExternalMethod.py have this problem using HTMLFile? TIA, Scott PS: I know I can get the id with def external_method( self, REQUEST = None ): return self.id but the real dtml_string I need to evaluate is much more complicated than '<dtml-var id>'...

<base> instead of SiteAccess
by George Osvald 22 Aug '00

22 Aug '00

I am using ProxyPass configuration with Apache and SiteAccess. My web-site is located on ISP's server in my user directory. Because I can't stay on line for too long during a day(I have a phone on the same line) I tend to do all editing off line and then at night upload the lot. The subdirectory of my web site is 'okstudio'. Because I am using SiteAccess(with 'base' in the folder 'okstudio'), none of the relative links worked on my local machine. I like my links nice and short that do not include '/okstudio/'. It looks too long in the address window of my browser. Before each upload to the server I had to change the links. I was trying to use SiteAccess on my home machine but could not get it working. It would not work for http://localhost or http://localhost:8080 ......and so and so. I tried several times without a success. Then I decided to use a different approach. I created a property 'base' in the root folder of my site. The string is: <base href="http://localhost:8080/okstudio/">. Then I put <dtml-var base> in my standard_html_header and all the alternative headers I use (JavaScript and stuff). All I have to do now is change the 'base' property to <base href="http://www.myserver.com.au/"> before each upload and all the links can stay the same. I would not even have to use SiteAccess at all if I had a little redirection method in my root directory. It is all OK but I would like to know if there is a way how to make SiteAccess working on the local machine so I can have almost identical setup locally. Can you help anyone? I am also serving local files located in my original public_html directory from ZOPE going directly to my user directory. The links look like this: http://123.45.678.9/~username . Would that be considered a security risk exposing my user directory like that? George Osvald

tree tag example fails
by jon＠totient.demon.co.uk 22 Aug '00

22 Aug '00

This example here :- http://www.zope.org/Members/anthony/tree-coding-tricks with the external method class _dummy: def __init__(self, name): self.name=name def child_lookup(parent): c = [] for i in range(0,5): c.append(_dummy("%s.%d"%(parent, i))) return c and dtml method <dtml-let name="0"> <dtml-tree id=name branches_expr="child_lookup(parent=name)"> <dtml-var name> </dtml-tree> </dtml-let> appears not to work on zope 2.2.0 or 2.1.6 on RH 6.2 with netscape 4.7x, python 1.5.2 Every node gets the label "0" and then stops expanding. I also tried a simple example starting with a root of 1 and computing leaves of 2x and 2x+1 but that also fails. Any ideas what is goind on? Jon

I would expect, it works as follows: like any DTML tag, "dtml-if" calls its name parameter (if it is callable). I expect that the result of this call is bound to the variable name. This means, "DestinationURL" which formerly was bound to a method, is now bound to the result of calling this method, i.e. to a string. Dieter
