Recursive <dtml-var> statements
by Kyle D. Lanclos 05 May '00

05 May '00

This is not the first time I've had to try and hack around Zope not letting me recurse <dtml-var> statements, but this is the first time that I haven't found a solution. My hair is turning greyer by the minute. Here's an example of what I'm trying to do: arguments: target_field:string old_value_list:list old_value:string new_value:string And the function replace() just does string.join(string.split(input, old_value), new_value). <dtml-in old_value_list> update table_name set <dtml-var target_field>= '<dtml-var "replace(sequence-item, old_value, new_value)" sql_quote>' where <dtml-var target_field>='<dtml-var sequence-item sql_quote>' <dtml-var sql_delimiter> </dtml-in> This would, if it ever works, generate statements like the following: update table_name set url='www.foo.org' where url='www.foo.com'; update table_name set url='www.bar.org' where url='www.bar.com'; update table_name set url='www.baz.org' where url='www.baz.org'; ...if I was generating update statements to replace .com with .org for certain values of title_field. All of my external methods and what-have-you are defined and accessible. I originally started out with the full string.join(string.split) hooplah instead of the function replace(), but this is where things currently stand. My problem? I can't access sequence-item within another dtml-var statement. This would not be an issue if I didn't have to modify the contents of old_value_list within the dtml-in statement. Accessing it directly via <dtml-var sequence-item> works perfectly fine, of course, but I can't just stick that within another dtml-var. If I could do this: <dtml-var "replace(<dtml-var sequence-item>, old_value, new_value)"> ...my life would be easy. I have tried representing sequence-item within the dtml-var in (at least) the following additional ways: _.REQUEST(['sequence-item']) _['sequence-item'] _.getitem(sequence-item) I originally had this whole mess shipped off to an external method, which worked just fine until the input list generated a return string longer than the max query length (16382ish), even though the return string was separated into single update requests as I described above. The whole reason I'm doing this within Zope is to get the <dtml-var sql_delimiter> tag on my side. Suggestions are very, very welcome.

Reload of Python Products
by Jason Spisak 05 May '00

05 May '00

Zopists, In light of Kevin D.'s recent document on PyProds or ZClasses, how difficult would it be to give all products the option of a reload tab? Some method you could include in your product to add a reload tab to the management interface?

how: passing a list as a hidden variable from doc to doc
by news-list.zope＠innominate.de 05 May '00

05 May '00

Hello Zopistas, I've come across this problem, (which delays my whole project and upsets my employer): I have a Form that displays a list of files for deletion and a checkbox for each file to select it: <dtml-in "prjfolder.objectIds('File')" skip_unauthorized> <input type=checkbox name=del_list value=<dtml-var sequence-item>> [...] Users can check the files they want to delete. They submit the form to the next dtml-method, say "delete". all checked filenames are passed to this method as a list object, e.g.: ['file1', 'file2', 'file3']. If I pass this list object to manage_delObjects(del_list), everything goes fine. The objects are deleted. Logical flow: select -> delete BUT: I have to ask the user if he really wants to delete the files. Thus: select -> ask -> delete So I need to pass the list of filenames through that darn "ask" document. There I did something like: <input type=hidden name=del_list:list value="<dtml-var "REQUEST['del_list']">"> this renders to: <input type=hidden name=del_list:list value="['file1', 'file2', 'file3']"> (Note: I did the :list type conversion. I also tried tokens, lines, whatever...) If the user chooses to delete, I finally call my delete document, which is supposed to delete the files in the list. but the call to manage_delObjects(del_list) fails with: Error Value: ['file1', 'file2', 'file3'] does not exist How do I pass a list object from one document to another? It always somehow becomes a string, breaking everything. There must be a clean way; I do not want to do string magic with split or so. Anyone help me out, please. thanks in advance, Heiko -- heiko.stoermer(a)innominate.de innominate AG networkingpeople fon: +49.30.308806-0 fax: -77 web: http://innominate.de

Hello, i want to create an image object that show its content only if the user have enough "power" to see it. I've created a Zclass, added my power property and then changed the view method with this one: <dtml-var standard_html_header> ... check the power and then if ok... <dtml-call "propertysheets.view_image_or_file"> <dtml-var standard_html_footer> But it's not working, why?
