workbench_alchemy's Issues

column default values produce invalid python code

Hi! Thx for that tool.
If i have in the MySQL create table following column definition:
mod_timestamp TIMESTAMP NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

I get following after running the script and python claims that this is invalid syntax:
mod_timestamp = Column(TIMESTAMP, default=CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP)

any idias how to fix this?

problem of "one to one relation" and "muti unique index"

firstly, thank you for this great tool, which save so much time of mine.
during my work, I found some problem about this tool:

• 1. one to one relation, why not use:
     uselist = False
• 1. multi unique index, this is inactive by using UniqueConstraint (mybe in some special sqlalchemy version or mysql version)

  UniqueConstraint('assailant_id', 'sample_id', 'sample_type', name='assailant_sample_uqe')
  

  instead below is active:

      __table_args__ = ({'mysql_engine': 'InnoDB', 'sqlite_autoincrement': True, 'mysql_charset': 'utf8'}
  , UniqueConstraint('assailant_id', 'sample_id', 'sample_type', name='assailant_sample_uqe'))
  

Primary key column renamed and aliased

When exporting this table from the database ...

CREATE TABLE IF NOT EXISTS ass_register.person (
idperson INT NOT NULL AUTO_INCREMENT,
lastname VARCHAR(45) NULL,
firstname VARCHAR(45) NULL,
PRIMARY KEY (idperson))
ENGINE = InnoDB

I get the idperson column renamed like so:

class Person(DECLARATIVE_BASE):

__tablename__ = 'person'
__table_args__ = (
    {'mysql_engine': 'InnoDB', 'sqlite_autoincrement': True, 'mysql_charset': 'utf8'}
)

id = Column(  # pylint: disable=invalid-name
    "idperson", INTEGER, autoincrement=True, primary_key=True, nullable=False
)
lastname = Column(VARCHAR(45))
firstname = Column(VARCHAR(45))

def __repr__(self):
    return self.__str__()

def __str__(self):
    return "<Person(%(id)s)>" % self.__dict__

As Professor Julius would say "Why is it so?"
P.S. Wonderful tool !
