[Zope-dev] ZPivotTable doesnt save its data dictionary

2001-05-13 Thread florian_reiser 

Hi folks,

I've started to program a pivot table.

Therefore I've created three classes:

ZPivotTable, Row and Cell.

The ZPivotTable class contains a set of Row classes, stored in a dictionary, as well 
as the Row classes contain a set of Cell classes stored in a dictionary.

Now I am debugging the product and can't find the reason why the table doesn't store 
the rows in its dictionary.

Could you please help me finding this bug.

The source is stored under the following address:
http://www.zope.org/Members/freiser/ZPivotTable/ZPivotTable-0.0.tar.gz

Thanks

Florian Reiser

florian,

without even looking at the code, when you use simple data types (lists,
dictionaries, etc) to store your data you have to make sure that the
persistence machinery gets tickled the right way whenever you update values.
with those simple storage datatypes it won't know things have changed unless
you specifically tell it.

you would need to do either something like this::

  self.my_storage_dictionary['newvalue'] = x
  self._p_changed = 1

or you could do it like this:

  dictionary = self.my_storage_dictionary
  dictionary['newvalue'] = x
  self.my_storage_dictionary = dictionary

or you could simply use one of the helper classes that come with zope, like
PersistentMapping. it emulates a dictionary and makes sure the persistence
machinery gets told about changes.

jens,

thanks for your reply. It helped me a lot.

Do you have me a tip how I can get all Z SQL Methods in an selection field.
I've found the superValues('Z SQL Method') function, but I'm having problems
using it, because it can only be used in python.

So how can I get the result returned from this function in my dtml form?

thanx in advance

florian,

as far as i know you can call superValues from DTML. it returns a list of
objects. you could do something like this:

dtml-in expr=folder_name.superValues(['Meta Type 1', 'Meta Type 2'])

  dtml-if name=sequence-start
select name=my_select_list
  /dtml-if

  dtml-with sequence-item only
option value=dtml-getId;dtml-title;/option
  /dtml-with

  dtml-if name=sequence-end
/select
  /dtml-if

dtml-else
  pbCannot find anything!/b/p

/dtml-in

jens,

thank you very much for your help. Now I've only get to work out how to get the 
results of the
query inside my Pivot table, so I can compute them.

Greetings
