In my existing Firebird database I have some views defined. In the model I thought I could just go ahead and define them basically like tables but I get an exception:
Traceback (most recent call last): File "saTest.py", line 4, in <module> import modelTest as model File "C:\Dev\BoaTest04\sqlalchemy\modelTest.py", line 237, in <module> vcbook = sao.mapper(Vcbook, vcbook_table) File "c:\downloaded software\python\sqlalchemy-0.4.0beta6\lib\sqlalchemy\orm\__init__.py", line 516, in mapper return Mapper(class_, local_table, *args, **params) File "c:\downloaded software\python\sqlalchemy-0.4.0beta6\lib\sqlalchemy\orm\mapper.py", line 152, in __init__ self._compile_tables() File "c:\downloaded software\python\sqlalchemy-0.4.0beta6\lib\sqlalchemy\orm\mapper.py", line 414, in _compile_tables raise exceptions.ArgumentError("Could not assemble any primary key columns for mapped table '%s'" % (self.mapped_table.name)) sqlalchemy.exceptions.ArgumentError: Could not assemble any primary key columns for mapped table 'vcbook' In my case the views are always used in read-only mode, changes are made to the actual table. |Is there someway I can define these views. I was able to work around the above exception by defining a primary key column or columns (compound key) but I have one or two views which don't really have a primary key. Appreciate any hints/tips.
