Hi,
once I switched from 0.1.7 to 0.2.2 I found many problems which I'm gradually
trying to resolve in favor of new interface. The one which stuck me is
cascade_mappers. Here is snippet of code which worked under 0.1.7:
map_tpr = mapper(T_PROCESSING,t_processing)
processingName = processing['processingName']
map_tpn = mapper(T_PROCESSING_NAME,t_processing_name)
cascade_mappers(map_tpn,map_tpr)
where lower case t_XXX are the tables and upper case T_XXX are the classes.
So, with new version I got that following error:
File "/home/vk/CMS/DBS/work/prototype/DBSSchema/DBSManager.py", line 561, in
createProcessing
cascade_mappers(map_tpn,map_tpr)
File "/home/vk/CMS/DBS/work/prototype/DBSSchema/__init__.py", line 108, in
cascade_mappers
File "build/bdist.linux-i686/egg/sqlalchemy/orm/mapper.py", line 885, in
__getattr__
AttributeError: table
I've compared orm/__init__.py (v0.2.2) with mapping/__init__.py (v0.1.7) code
and looks like cascade_mappers functions are the same.
Some help, explanation, would be helpfull.
Thanks,
Valentin.
