If your variable is named NAME, you can use <dtml-var NAME> If there is a potential name clash and you want to be sure, you get the NAME in REQUEST, you can use: <dtml-with REQUEST> <dtml-var NAME> </dtml-with> If you want an error, when REQUEST does not define NAME, i.e. you do not want a NAME that comes from somewhere else, you can use <dtml-with REQUEST only> <dtml-var NAME> </dtml-with> or <dtml-var "REQUEST[NAME]">.

Re: [Zope] Is there a function which evaluate a python expression situated in a string variable ?

It is, however, not exported to DTML. Thus, you need an external method. Dieter

A minor clarification of terms: * *acquisition* acquires attributes/methods form containing objects or the context of the objects use * DTML methods usually are passed a *namespace* containing name->value bindings. This namespace contains many variables, REQUEST and its content, acquired attributes/methods, variables made available with <dtml-with>, <dtml-let>, <dtml-in>, <dtml-tree>... Z SQL methods do support acquisition. They are, however, not called (automatically) with the current namespace but only with the REQUEST object. Thus, they can automatically use only acquired attributes/methods and variables contained in REQUEST but not the variables defined in an enclosing DTML method (via with, let, in, tree ....). Acquired attributes do not need tp be listed in the "Arguements" property of the Z SQL method, REQUEST variables have to. Dieter

Hi. Well Ive done a clean install of GUF and 2.2. Ive followed the instructions to the letter in installing SQL for GUF and no matter what I do I cannot get the damn thing to work. I have even set all users to have access to all things. And that doesnt work. Has anyone else had this total failure at getting anywhere, or is it just me? Thanks. Andy McKay

One of the list elements is empty, there is no index "0". Try: <dtml-if "item[7:8] == '-'"> .... contains '-' as 8.th character .... </dtml-if> "item[7:8]" gives the 8.th character, if it exists, and otherwise the empty string. Dieter

E.g.: <dtml-call "REQUEST.set('actions',1)"> <dtml-if "action == 'insert'"> ... insert ... <dtml-elif ... <dtml-else> <dtml-call "REQUEST.set('actions',0)"> .... </dtml-fi> <dtml-if actions> .... updated order ..... </dtml-if> Probably, Zope should have a "dtml-set" which would allow to update a new "REQUEST.vars" directory. Many questions in this list would go away, if assignment could be done with an explicit dtml tag. Dieter

I think, this would be nice to have. Currently, I do not need it and therefore would not spend relevant time for it. Dieter

RE: [Zope] A Description with a Search Engine using the advanced ZCatalog program ?
by Chris McDonough 20 Jul '00

20 Jul '00

The ZCatalog doesn't return the actual object that is indexed. It returns a representation of the object in the form of a "brain" which you can use to reference the object. <dtml-in Catalog> <dtml-with sequence-item> <dtml-var "Catalog.getobject(data_record_id_).myMethod()"><br> </dtml-with> </dtml-in> This snippet iterates over all the results from a catalog and calls the myMethod() method on every one of the objects referenced by the returned results. "data_record_id_" is an attribute of the "brain" object returned from the catalog search. "getobject" is a method of the Catalog which returns the actual object referenced by the "data_record_id_". > -----Original Message----- > From: Jonathan Desp [mailto:jonathandesp@atomasoft.com] > Sent: Thursday, July 20, 2000 3:02 PM > To: zope zope zope > Subject: [Zope] A Description with a Search Engine using the advanced > ZCatalog program ? > > > > An accurate question here: > > I read the page: > > http://www.zope.org/Members/Zen/howto/AdvZCatalogSearching > > But I'm not able to understand very much, what is the section > where they are > talking about "a small description for every result" you are > getting from > the ZCatalog search engine ? > > My site is almost ready !
