Just my 2 cents. Using the DAL on anything but web2py is going to be a pain in the ass and a nightmare waiting to happen. This is due to its inherent forced procedural coding style. You "can" wrap DAL calls as methods, but it just gets really messy. I'm a clean code zealot, so I bet I care more than most.
For any kind of software your developing that uses object oriented programming, use a database system that is structured around classes and declarative bases. You will find this is much much much easier to integrate into, for example a wxWidgets program, than the DAL is. -- Thadeus On Sat, Oct 30, 2010 at 7:29 AM, Stef Mientki <stef.mien...@gmail.com>wrote: > On 30-10-2010 12:06, rochacbruno wrote: > > Look this simple example: > > http://bitbucket.org/rochacbruno/dal_on_flask/src/tip/dalFlask.py > > > I have a PyGTK app running very well, I will put the code online soon. > > hi Bruno, > > one other question, > in the gtk application, > do you access the database through a local server, > or direct through a local disk location ? > And in the latter case, how do you specify a hard disk location ? > > thanks, > Stef > > > > > Em 30/10/2010, às 06:33, Stef Mientki <stef.mien...@gmail.com> escreveu: > > Interesting ... > as I want to migrate to web2py > and want to have some kind of DAL for my desktop applications, > this sounds very good. > > Can you give me some guide lines, how to use the web2py DAL for desktop > applications ? > > thanks, > Stef Mientki > > > On 19-10-2010 05:44, Bruno Rocha wrote: > > I know DAL was not made for that, but I'm using the DAL in a desktop > application with PyGTK, and it is working very well :-) > > It is a simple application that monitors the presence of employees in a > company and reads small CSV files from a time clock, > people has cards that open the gates/doors of the company factory, I use a > stream to read the track from serial port of time clock, > then, I take the information serialized as CSV, I parse and write it into > SQLite db, after that , the Janitor uses a PyGTK app to access that > information. > > already been running for about 6 months, So far everything is working fine, > but I can not run the automatic migrations. > > Does anyone know a way to make migration work automatically with DAL Stand > Alone? > > I'm importing sql.py I'm connecting with SQLite, setting tables, accessing > and doing out any crud operation. > > The only thing missing is to make migration works. > > I already set migrate='Mytable.table' and I tried with migrate=True > > ---- > An example of what I have working in my > > "connect.py" > >>> from gluon.sql import * > >>> db = DAL('sqlite://timeclock1.db') > >>> Track = > db.define_table('track',Field('regnumber','integer'),Field('action','integer'),Field('timestamp','datetime'),migrate='track.table') > > "Form_workflow.py" > >>> Track.insert(regnumber=123,action=2,timestamp='2010-10-19') > 1 > >>> Track.insert(regnumber=124,action=2,timestamp='2010-10-19') > 2 > >>> db.commit > > Until here, its ok. > > But now I am wanting to change the model, and including > Field('department') > > "connect.py" > >>> Track = > db.define_table('track',Field('regnumber','integer'),Field('action','integer'),Field('timestamp','datetime'), > *Field('department')*,migrate='track.table') > > Traceback (most recent call last): > File "<stdin>", line 1, in <module> > File "/bin/DAL/gluon/sql.py", line 1346, in define_table > raise SyntaxError, 'invalid table name: %s' % tablename > SyntaxError: invalid table name: track > >>> > > ---- > > If this is not possible, I'll have to create new fields in SQLite and then > update my model. > > > >
