[web2py] how to derive a class from Table ?
hello, I'ld like to derive a new class from Table (if it succeeds, I can integrate DAL into my existing programs, without changing anything, except adding an import statement) This seems to be the obvious way, the problem is that although a table seems to be created, the Table is not attached to the database. So writing to the database disappears in the universe. class DAL_Table ( Table ) : def __init__ ( self, DB, Name, Defs, Drop = False, Mod_Table = False ) : ... do my preprocessing, generate Fields Table.__init__ ( self, DB, Name, *Fields, migrate = Name + '.table' ) This ones create a table attached to a database, but the DAL_Table doesn't hace the properties of Table class DAL_Table ( object ) : def __init__ ( self, DB, Name, Defs, Drop = False, Mod_Table = False ) : ... do my preprocessing, generate Fields My_Table = DB.define+table ( Name, *Fields, migrate = Name + '.table' ) ... but now DAL_Table doesn't have the properties of Table thanks, Stef Mientki
Re: [web2py] how to derive a class from Table ?
I'm not sure if you can do this with DAL. However, maybe if you use an ORM you can derivate models. Time ago someone write about using Django ORM or SQLAlchemy in web2py for make this, you can read here [1] and here [2]. Correct me if i am not on the right way, thanks.

[web2py] Re: how to derive a class from Table ?
Can you explain the purpose? You can create a derivative class of
Table (is it just a table) but this is not the same as model
inheritance in ORMs, becuase tables (lower case) are not classes in
DAL. To do model inheritance
db.define_table('a',*fields)
db.define_table('b',db.a,*other_fields)

[web2py] An upsert in database
Hi, I need to do an upsert in a database table. I need to insert a row if it does not exist already and and update it if it does. using python sqlite module I was writing the code as code (python : curs holds the cursor to table ): curs.execute(insert or ignore into table values(?,?),(name_var,0)) curs.execute(update docs set freq=freq+1 where name ='+name_var+ ') The table contains two columns : name (type text, primary key) and freq (type integer). it name_var is a variable that holds the name to query the database. How do I achieve the same code in web2py? I tried db.executesql() but am having problem with it because of the quotes involved. Thank you.

[web2py] little bug in last web2py (maybe in a few last releases also)
hello, when you define a field in a table as a decimal(x,y) , the form
widget renders it as an input class=decimal(x,y) .../ .
I'm not perfectly sure that before worked right, because I noticed the
behaviour writing a letter accidentally inside a field, but I guess
before class for inputs of type decimal(x,y) would be simply rendered
as decimal.
the current web2py_ajax checks for decimal as a class with the
following snippet
jQuery('input.double,input.decimal').keyup()
-
and in this way pre-validation does not work.

The problem was that I was using self.session.forget() thinking that that would take care of getting rid of all of the session info. As soon as I got rid of that line though, everything worked as normal... As for references in python, that is how I thought python worked (coming from C++), but this behavior gave me some doubt.

[web2py] Paypal Digital Download
Hello! I am working on a project that requires a Digital Download where the
download is provided after the payment has been sent to paypal.
The documentation on Paypal in web2py is very confusing and I don't know if
its for the purpose of what I need. I am generating a paypal/button for
express checkout. and I am trying to think of ways I can then redirect the
user to a page where they can download the product
Normally this would be simpler but I have multiple people selling there
different products and with that multiple products
here is my paypal code
br /br /
form name=_xclick action=https://www.paypal.com/cgi-bin/webscr;
method=post
input type=hidden name=cmd value=_xclick
input type=hidden name=business
value={{=db.auth_user[row.userinfo].email}}
input type=hidden name=currency_code
value={{=db.currency_paypal[row.currency].current}}
input type=hidden name=item_name value={{=row.product_name}}
input type=hidden name=no_shipping value=1
input type=hidden name=custom value={{=row.id}}
input type=hidden name=amount value={{='%.2f'%float(row.price)}}
input type=hidden name=return value= /
input type=hidden name=cancel_return value=/
input type=image src=http://www.paypal.com/en_US/i/btn/btn_buynow_SM.gif;
border=0 name=submit alt=Make payments with PayPal - it's fast, free
and secure!
/form
So my question is: How can I use paypal for a digital download using the
express checkout button? Do I need to create an IPN class and add notify_url
to my paypal code if so can some one provide an example
*cheers

[web2py] Re: Passing pointer to session, requestion, etc objects to module
It's just a nice pattern to follow when building modules that need access to the response/response/session. Instead of passing them all individually, you can just pass globals() and everything you need is there, similar to auth and crud. auth = Auth(globals(),db) crud = Crud(globals(),db) On Oct 31, 4:36 pm, b00m_chef r...@devshell.org wrote: The problem was that I was using self.session.forget() thinking that that would take care of getting rid of all of the session info. As soon as I got rid of that line though, everything worked as normal... As for references in python, that is how I thought python worked (coming from C++), but this behavior gave me some doubt. Thanks for the pointer to look at the environment argument, though that didn't give any useful info...was there anything particularly interesting about that argument in that class?

[web2py] multiple select contains
Hello,
I'm juste trying to use contains with a custom FORM, but it does not
work with FORM(SELECT,_multiple=True
Here is a piece of my controller:
def rebuts():
#Formulaire de saisie des rebust
ListeArticle=db(db.Article.id0).select(orderby=db.Article.CodeArticle)
Selection=FORM(TABLE(TR(
(TD(De l'article,SELECT(_name='DebArt',
*[OPTION(ListeArticle[i].CodeArticle,
_value=str(ListeArticle[i].CodeArticle)) for i in
range(len(ListeArticle))]))),
TD(A
l'article,SELECT(_name='FinArt',*[OPTION(ListeArticle[i].CodeArticle,
_value=str(ListeArticle[i].CodeArticle)) for i in
range(len(ListeArticle))])),
TD(Test,SELECT(_name='Test',_multiple=True,*[OPTION(ListeArticle[i].CodeArticle,
_value=str(ListeArticle[i].CodeArticle)) for i in
range(len(ListeArticle))])),
TD(De la date (-MM-JJ), INPUT(_name='Debut', requires =
IS_DATE(error_message=T('Doit être de la forme -MM-JJ !',
TD(A la date (-MM-JJ), INPUT(_name='Fin',requires =
IS_DATE(error_message=T('Doit être de la forme -MM-JJ !',
TD(Sélectionner,
INPUT(_type='submit',_value='Sélectionner')
if Selection.accepts(request.vars,keepvalues=True):
pass
DebArt=request.vars.DebArt
Debut=request.vars.Debut
Fin=request.vars.Fin
FinArt=request.vars.FinArt
Test=request.vars.Test
[...]
query5=db(db.GPOF.OF_CART.contains(Test)).select()
[...]
return dict(query5=query5,Test=Test)
If I submit one value to the Test field = query5 act as I want
(=returns db.GPOF whose field OF_CART=Test)
If I submit more than one value to the Test Field = query5 does not
return anything.
I guess this question have already been asked around there but I
cannot find it through the group.
Can somebody help me with this , I'd like to returen all rows db.GP_OF
whose field are selected via the Test multiple select field
Thanks a lot

I thought I did, but probably I had other bugs then,
indeed it works without the file///' prefix,
both with forward and with backward slashes.
thanks,

On linux you don't need to specify file:/// you can just give the full path.

This works:
Database_Name = 'ID_TO_Beheer_DAL.db'
DB = DAL_DB ( 'sqlite://' + Database_Name )
This gives an error, saying couldn;'t find a database after 5 tries
Database_Name = r'D:/Data_Python_25/Beheer/ID_TO_Beheer_DAL.db'
DB = DAL_DB ( 'sqlite://file:///' + Database_Name )
A workaround is to use os.chdir()

[web2py] prefork or worker mpm for apache embedded mode
The preferred apache configuration for mod_wsgi applications is to run in daemon mode. But if the application is to be run in embedded mode, which one is preferred: prefork mpm or worker mpm ? And, is DAL threadsafe ?
