- Zope - Zope lists

General ZOPE Programming Question
by Michael Lausch 05 Mar '00

05 Mar '00

I want to do the following tasks A user enters a list of products. Such a list is equivalent to an order. Then i want the user to enter some things for each product. I don't want to implement DTML pages for each combination of products and i want to present one entry screen for each order. I tried the following approach: I created a Folder named 'Products'. In this folder i created subfolders named after the prducts code number, e.g. `4007', `4008'., .... In each of these folders i defined a DTML Method `New' which hholds the DTML code to create an input form fr this product. My plan is also to create methods named 'Display', 'Edit', .... so i can render the objects in different ways. In anotehr page i want to do something like: <dtml-in products> <dtml-var "URL1 + '/Products/' + _['sequence-item'] + '/New'"> </dtml-in> but this doesn't work. Nothing is displayed. I also tries <dtml-var expr="...."> and <dtml-call "..."> (the last one was pure desperation). So what's the correct method for implementig such a system?

URL1?
by Lucas Vogel 05 Mar '00

05 Mar '00

I see a lot of references to this variable, yet it isn't documented anywhere I've looked. Is this the base URL, or the URL leading up to the document that references the variable? Thanks again -- Lucas Vogel lucas7(a)home.com ICQ: 44697169

traversing up the level
by Lucas Vogel 05 Mar '00

05 Mar '00

I want to put in an <a HREF> link to a document that is up about two or three levels from the document referencing it. Do I use the PARENTS variable? I remember someone telling me before, but I can't find the email and I can't find it in any of the documentation. Thanks -- Lucas Vogel lucas7(a)home.com ICQ: 44697169

hi, i've got two questions dealing with gadfly and python scripting using external methods (Zope). 1. how to set the column- and table-name dynamically in a sql-query ? i.g. c.execute("select var1 from var2") 2. what's wrong if there is no table-update after invoking c.execute("update ...") c.commit() (autocheckpoint enable) thanks for your help rico

Re: [Zope] bobobase_modification_time syntax
by Alexandre Ratti 05 Mar '00

05 Mar '00

Hello Tim, - To get the modify time for a file, use this code in a DTML document or method: <dtml-with yourFileName> <dtml-var bobobase_modification_time> </dtml-with> or <dtml-var "yourFileName.bobobase_modification_time()"> - If your filename includes a dot, use instead: <dtml-with "_['yourFileName.gif']"> <dtml-var bobobase_modification_time> </dtml-with> or <dtml-var "_['yourFileName.gif'].bobobase_modification_time()"> Cheers.
