sqlobject-discuss Mailing List for SQLObject (Page 20)

Everything was running fine last night.  Came in this morning and my 
test system is acting weird.  I'm doing my best to find the answer but 
in the meantime, if someone knows what this is, I could use a bit of help.

Thanks,

Glenn

Hello!

I'm pleased to announce version 1.3.0, the first stable release of branch
1.3 of SQLObject.


What is SQLObject
=================

SQLObject is an object-relational mapper.  Your database tables are described
as classes, and rows are instances of those classes.  SQLObject is meant to be
easy to use and quick to get started with.

SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite,
Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB).


Where is SQLObject
==================

Site:
http://sqlobject.org

Development:
http://sqlobject.org/devel/

Mailing list:
https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss

Archives:

What's New
==========

Features & Interface
--------------------

* PostgresConnection performs translation of exceptions to standard
  SQLObject's hierarchy of exceptions.

* Major update of FirebirdConnection: introspection was completely
  rewritten and extended; ``charset`` was renamed to ``dbEncoding``;
  a longstanding bug was fixed - pass port to connect().

Ok.. thank you. I was under the impression that this function will add an
column automatically to my database after I included it in my class. I
might code this functionality into sqlmeta. I would find this to be very
useful for future changes.

   You've got it in the reverse direction. fromDatase gets the list of
columns *from* database. If you want to add a column from python to
database you ought to use sqlmeta.addColumn() with changeSchema set to
True.

   I have problems understanding the sentence. Did you add a column to
your database and then restarted the program? The program didn't
discover the new column? You can test the list of columns by printing
Company.sqlmeta.columnList and Company.sqlmeta.columns.

Hi Jeremy,
what about the Naming Style?
see: Changing the Naming Style <http://sqlobject.org/SQLObject.html#id56>
.... By default names in SQLObject are expected to be mixed case in Python
(like mixedCase), and underscore-separated in SQL (like mixed_case). This
applies to table and column names.

Regards

Petr

Sorry.. the previous post was in error.
Thank you for your help but although I am not receiving any errors. The
 fromDatabase boolean doesn't seem to be performing its stated function.It
does not update the database when i enter a new column in the database.

fromDatabase:A boolean (default false). If true, then on class creation the
database will be queried for the table's columns, and any missing columns
(possible all columns) will be added automatically.
I started with these
class Company(SQLObject):
class sqlmeta:
        fromDatabase = True
        lazyUpdate = False
        cacheValues = True
    Company_Name = StringCol(length = 256, default = None)
    Company_Address = StringCol(length = 256, default = None)
    Company_Phone = StringCol(length = 256, default = None)

Added
class Company(SQLObject):
class sqlmeta:
        fromDatabase = True
        lazyUpdate = False
        cacheValues = True
    Company_Name = StringCol(length = 256, default = None)
    Company_Address = StringCol(length = 256, default = None)
    Company_Phone = StringCol(length = 256, default = None)
    *Company_Number = StringCol(length = 256, default = None)*

class Companys():
    def __init__(self):
         Company.createTable(ifNotExists = True, connection=conn)

Output:>>
 2/QueryAll:  SHOW COLUMNS FROM store
 2/QueryAll:  SHOW COLUMNS FROM company
 2/Query   :  DESCRIBE company
 2/Query   :  DESCRIBE store

   Here is the problem now - Company (and Companys) is imported before
a connection is created. You have to open a connection before the class
Company is created (i.e., before the module is imported).

Yes. If I remove Companys as a SQLObject.I still receive the same error.
I'm not sure from the sequence of the ( from Company import Companys ) is

   I clearly see here that Companys is an SQLObject and hence require a
connection.

           Programmers don't die, they just GOSUB without RETURN.

 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*

 from sqlobject import *
 from pySMS import Companys

   What's that? A global function or a method? Where it's called?

   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.

   A number of problems here.
1. The connection is created in Companys.__init__ which is not called,
at least it is not called when SQLObject's metaclass processes
fromDatabase. fromDatabase requires an open connection.
2. A transaction is opened but never used. Transaction (trans, in your
case) has to be used instead of connection (in sqlhub, or in every
SQLObject call that accepts connection).

           Programmers don't die, they just GOSUB without RETURN.

I have a problem while trying to use the "fromDatabase = True" option in
sqlmeta. Any time I enable this. it gives me the connection error below. Is
there another attribute I need to do before doing this? I saw another
thread with this problem but the solution was enable the connection before
the class which I have done.

from sqlobject import *

     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=conn)
        Company._connection.debug = True

class Company(SQLObject):

    class sqlmeta:
       fromDatabase = True

Indeed.  Sorry.  I misread that sentence and thought it referred

Brilliant.  Thank you very much.
It is either that, or just pray patiently that
Ubuntu will upgrade it in the next release next month :-)

Hi,

sorry if this is an old topic, but I did not find any list
archive.  I just took up using SQLObject a few weeks ago;
very convenient.

I wonder if anyone has experience with a bug where the
the postgress connection attempts to call a boolean
value (autocommit) as a method.  (Call stack is cut in below.)
It is not a new problem, I found it reported here as well:
http://stackoverflow.com/questions/6374121/python-why-does-sqlobject-fail-in-conn-autocommit1

What is odd is that my code works fine on Ubuntu 10.4 with a connection
to localhost.  When I run the same code on Ubuntu 10.10 with a remote
server, it fails.  I am not sure if the difference is with the
remoteness or the software version ... So far I have tried to make do
 with the standard ubuntu packages for sqlobject and postgres.

Does anyone know if this problem has been resolved in some recent 
version of sqlobject/psycopg?  Or if there is a known workaround?
I do observe that the URL below suggests what looks like a 
downgrading of psycopg2, which I won't do if upgrading is an option :-)

My call stack is:
  File "/home/georg/git/pysteg/src/pysteg/sql/tables.py", line 346, in
getJob
    trans = conn.transaction()
  File "/usr/lib/pymodules/python2.7/sqlobject/dbconnection.py", line
400, in transaction
    return Transaction(self)
  File "/usr/lib/pymodules/python2.7/sqlobject/dbconnection.py", line

  File
"/usr/lib/pymodules/python2.7/sqlobject/postgres/pgconnection.py", line

    conn.autocommit(1)

Thanks a lot in advance,

   To fix that edit sqlobject/mysql/mysqlconnection.py, method
columnsFromSchema; search for assignments

kw['name'] = soClass.sqlmeta.style.dbColumnToPythonAttr(field)
kw['dbName'] = field

   make them strings:

kw['name'] = str(soClass.sqlmeta.style.dbColumnToPythonAttr(field))
kw['dbName'] = str(field)

   test and report if that helps.
