Is there any way to have a Non auto increment integer primary key? I
have this model:
class Component(Base):
__tablename__ = 'Component'
appCode = Column(ForeignKey('Application.appCode'),
primary_key=True, nullable=False)
componentEnumID = Column(ForeignKey('Enumeration.enumID'),
primary_key=True, nullable=False, autoincrement=False)
And when I try and insert into it I get this warning:
Column 'Component.componentEnumID' is marked as a member of the
primary key for table 'Component', but has no Python-side or
server-side default generator indicated, nor does it indicate
'autoincrement=True' or 'nullable=True', and no explicit value is
passed. Primary key columns typically may not store NULL. Note that as
of SQLAlchemy 1.1, 'autoincrement=True' must be indicated explicitly
for composite (e.g. multicolumn) primary keys if
AUTO_INCREMENT/SERIAL/IDENTITY behavior is expected for one of the
columns in the primary key.
And it ignores the values I provide for componentEnumID and generates
SQL without that column, which then fails with:
Cannot insert the value NULL into column 'componentEnumID', table
'DEC_CORE.dbo.Component'; column does not allow nulls. INSERT fails.
How to get around this issue?
