Re: [SQLObject] SqlObject Sqlmeta fromDatabase problem

[Jeremy H. <jer...@gm...>]

 What's that? A global function or a method? Where it's called?
*It is the Companys class. It is called from my test0.py file. See below.*
*
*
 The same problem - no connection has been defined. The code tried to
open a connection in Companys.__init__, but Companys is an SQLObject's
table and thus requires an open connection.
 Open a connection outside of SQLObject's initialization.

*Companys is not a sqlobject table. Company is a sqlobject table. Sorry for
the confusion. I chose poor naming. Do I not need to extend the SQLObject
in Companys? See all of them below.*

*Company.py file *
class Company(SQLObject):
    class sqlmeta:
       fromDatabase = True
       lazyUpdate = True
       cacheValues = True
   Company_Name = StringCol(length = 256, default = None)
   Company_Address = StringCol(length = 256, default = None)
   Company_Phone = StringCol(length = 256, default = None)

class Companys(SQLObject):
     def __init__(self):
         connection_string = 'mysql://user:password@127.0.0.1:3306/pySMS'
         conn = connectionForURI(connection_string,debug = True,autoCommit
=True)
         trans = conn.transaction()
         sqlhub.processConnection = conn
         Company.createTable(ifNotExists = True, connection=trans)

 *test0.py file*

 import sys
 from sqlobject import *
 from pySMS import Companys

 if __name__ == "__main__":

     pysoft = Companys()
