I was playing with SqlSoup in preparation to use it in a new (production)
project (sqlalchemy version 0.5.0beta3). I was testing with MySQL InnoDB
tables. The SqlSoup wiki page, and source code docstring, imply that a
SqlSoup.flush() will commit the data. I quickly realized that this is NOT
the case when using transactional InnoDB tables as shown below (although
non-transactional ISAM tables work fine).
Note that if I execute sqlsoup.Session.configure(autocommit = True)
everything works as expected. Please correct me if I have this wrong, this
is my first time using SqlSoup.
Assuming that the explicit commits ARE needed (i.e. I am not doing something
wrong), then I think that the wiki page and doc string should be fixed to
clarify this issue. I also think it would be a good idea to include
.commit, .rollback, and .begin methods on the SqlSoup class as I did
below.
Note, I WANT to explicitly issue the .commit's, so I hope I am
understanding this correctly. I just need some clarification. I cannot
find much recent information on SqlSoup by searching this list. Is it
supported? Is it used? Can it be used in a production environment?
Thanks,

if __name__ == "__main__":
db = SqlSoup("mysql://xxxx:[EMAIL PROTECTED]/test")
Test = db.test # Get the table def w/o echo
print "This does NOT commit:"
db.bind.echo = True
Test.insert()
db.flush()
print "\nBut this will commit both inserts"
Test.insert()
db.commit()
