Hi,
I believe I'm getting a handle on using dip with sqlalchemy - thanks for
the SQLA adapters.
Questions:
When using the declarative view is there a way not to use a spinbox for
integers?
Does the 'Grid' work? I'm not providing the traceback because it's
likely I'm doing something wrong.
Error with Floats:
Even after providing a type_map in sqla_imodeltype_adapter.py I get an
error (see below). Would you take the time to explain what I need to do.
I added the following :
# The map of the types used to handle each supported SQLAlchemy
type. Note
# that the order might be important so we don't use a dict.
# FIXME: Add support for more types.
_type_map = (
(SQLA_Boolean, Bool),
(SQLA_Integer, Int),
(SQLA_String, Str),
#
(SQLA_Float, Float),
(SQLA_Enum, Enum),
)
The error:
File "/home/johnf/Dip/dip/temp1.py", line 25, in <module>
class ReceiptHist(Base):
File "/home/johnf/Dip/dip/temp1.py", line 32, in ReceiptHist
