You want to get the length of a list, in your case the return value of "objectIds". This is a FAQ: you use "_.len(<list expression>)" or (insided a dtml-in) "<dtml-var sequence-length>". Dieter

Changing list elements (was: [Zope] 2d list manipulation)

There is no easy and safe way to do it in DTML (because a list does not have a method to replace a list element. If interested in a hack, you may look at the list methods "remove" and "insert"). The easiest thing is to write an external (or Python) method. Dieter

Folderish Properties
by Tim Cook 10 Sep '00

10 Sep '00

I have a folderish ZClass with a set of properties. When I create an instance via DTML my code doesn't update the properties from REQUEST. I use exactly (names changed of course) the same code to instantiate a document like ZClass and it works fine. So what's the difference between Folderish ZClasses & Document ZClasses in assigning to their properties? (The instance IS created, just the properties aren't assigned values.) I used the howto on adding instances via DTML change to the '_add' methods in both ZClasses. Here's the code FWIW: --- Document-'ish' --- <dtml-var standard_html_header> <dtml-call "REQUEST.set('id',REQUEST['med_name'])"> <dtml-call "REQUEST.set('title', REQUEST['med_name'])"> <dtml-call "REQUEST.set('online_lookup', REQUEST['online_lookup'])"> <dtml-call "REQUEST.set('indications', REQUEST['indications'])"> <dtml-call "REQUEST.set('contraindications', REQUEST['contraindications'])"> <dtml-call "REQUEST.set('warnings', REQUEST['warnings'])"> <dtml-call "REQUEST.set('alt_names', REQUEST['alt_names'])"> <dtml-call "REQUEST.set('dose_delivery', REQUEST['dose_delivery'])"> <dtml-call "REQUEST.set('doc_type', REQUEST['doc_type'])"> <dtml-with "manage_addProduct['FreePMProduct']"> <dtml-call "DrugClass_add(_.None, _, NoRedir=1)"> </dtml-with> <center> <H2><dtml-var med_name> was added.</H2> <p> <a href="formulary"> Back to Formulary Menu </a> </center> <dtml-var standard_html_footer> --- Folder-'ish' --- <dtml-var standard_html_header> <dtml-call "REQUEST.set('id',REQUEST['login_id'])"> <dtml-call "REQUEST.set('login_id', REQUEST['login_id'])"> <dtml-call "REQUEST.set('first_name', REQUEST['first_name'])"> <dtml-call "REQUEST.set('middle_name', REQUEST['middle_name'])"> <dtml-call "REQUEST.set('last_name', REQUEST['last_name'])"> <dtml-call "REQUEST.set('honorific', REQUEST['honorific'])"> <dtml-call "REQUEST.set('generation', REQUEST['generation'])"> <dtml-call "REQUEST.set('gender', REQUEST['gender'])"> <dtml-call "REQUEST.set('fda_number', REQUEST['fda_number'])"> <dtml-call "REQUEST.set('supervisor_id', REQUEST['supervisor_id'])"> <dtml-call "REQUEST.set('job_title', REQUEST['job_title'])"> <dtml-call "REQUEST.set('created_by', REQUEST['created_time'])"> <dtml-call "REQUEST.set('created_time', REQUEST['created_time'])"> <dtml-with "manage_addProduct['FreePMProduct']"> <dtml-call "ProviderClass_add(_.None, _, NoRedir=1)"> </dtml-with> <center> <H2><dtml-var login_id> was added.</H2> <p> <a href="providers"> Back to Provider Menu </a> </center> <dtml-var standard_html_footer> As Always - Thanks! -- Tim Cook -- FreePM Project Coordinator http://www.freepm.org OS Health Care Alliance Supporter http://www.oshca.org

keeping Java Servlets session ids based on url rewriting
by albert boulanger 10 Sep '00

10 Sep '00

I am using the latest Zope release using ZServer directly (but will be running under Apache....) I need to coordinate Zope based sessions and servelet sessions. We will be using url rewriting (I know use cookies, but we are doing worst case planning.). As you may know the rewritten urls that the servlet does look like http://foo/bar;$<id here>$. I need to retain the stuff after the ;. This seems to be dropped i think in ZServer. I was going to store the servlet sesssion id in a SQLSession object by having the servlet do a response redirect to a dtml method to process the id after the ;. Will Apache frontending and setting the CGI-vars fix this issue? A more general question, has anyone worked on the general cross-session issues like this? I think this is consideration item for the new session support in Zope.

Thinking about it again makes me realize that it will not work, since set just sets a variable, but does not take care of assignments. It is a little bit hard to explain, maybe someone else can do a better job. Here is what you would have to do: <dtml-var standard_html_header> <dtml-call "REQUEST.set('a', [[0, 0], [0, 0]])"> <dtml-call "REQUEST.set('a1', a[0])"> <dtml-call "a1.insert(0, 1)"> <dtml-call "a.insert(0, a1)"> <dtml-var "a[0][0]"> <dtml-var standard_html_footer> This code is tested and works. But you will see that this is far too complicated, thats why I would suggest you use a Python Method or an Eternal Method to solve the issue.

2d list manipulation
by Tim Russell 09 Sep '00

09 Sep '00

Hey, I'm having trouble accessing variables in a 2-dimensional list. Here's the creation code: <dtml-call "REQUEST.set('col', [])"> <dtml-in "_.range(0, 24)"> <dtml-call "col.append([])"> <dtml-let hour="_['sequence-item']"> <dtml-in "_.range(0, hour_divisions)"> <dtml-call "col[hour].append(0)"> </dtml-in> </dtml-let> </dtml-in> This creates a list variable, col, which contains 24 lists, each of which have <hour_divisions> elements of value 0. I can easily access the value of an element using: <dtml-var "col[index1][index2]"> However, the difficulty comes when trying to change the value of one of these elements. I've tried a handful of techniques, mostly offshoots of this: <dtml-call "REQUEST.set('col[index1][index2]', 5)"> to no avail. Does anyone have a solution to this? Thanks much... --Tim
