With the binding, you can use Gda for web applications.
You just need to import the library.
I made a example in Python 3 with cherrypy library for the web server.
Hope it helps !
import cherrypy
from gi.repository import Gda
from gi.repository import GLib
class MyWebsite (object):
def __init__(self):
self.conn = None
self.list_names = []
self.setup_database()
self.insert_data()
self.get_data()
def setup_database(self):
self.conn = Gda.Connection(provider =
Gda.Config.get_provider("SQLite"),
cnc_string =
"DB_DIR=.;DB_NAME=test")
self.conn.open()
try:
dm = self.conn.execute_select_command("select * from user")
except GLib.GError:
self.conn.execute_non_select_command("create table user (id
integer primary key, username text)")
self.conn.close()
def insert_data(self):
self.conn.open()
b = Gda.SqlBuilder(stmt_type=Gda.SqlStatementType.INSERT)
b.set_table("user")
b.add_field_value_as_gvalue("username", "John")
try:
stmt = b.get_statement()
self.conn.statement_execute_non_select(stmt, None)
except GLib.GError:
print("insert error !")
self.conn.close()
def get_data(self):
self.conn.open()
try:
# get all names
dm= self.conn.execute_select_command("select * from user")
iter = dm.create_iter()
while(iter.move_next()):
l = [Gda.value_stringify(iter.get_value_at(1))]
self.list_names.append(l)
except GLib.GError:
print("Error getting data")
self.conn.close()
for name in self.list_names:
print(name)
def index(self):
return "Hello " + str(self.list_names[0][0])
index.exposed = True
cherrypy.quickstart(MyWebsite(), config="cherry.conf")

Is not a Django problem.
GdaData library gives you access to database objects through a
Vala/GObject API and is inspired on Django. Thats all about Django.
I try, as a test, use apache mod_phython to run a GObject
Introspection code accessing to a database through a GDA query but
when I return the Gda.DataModel simply don't shows any value on
printing to the web page.
The point here is how can I use PyGObject on web. Could be a plus if
it can be used in any web framework.

Which, in this case, makes it a Django related problem :-) I may be
able to help with that, but I would need an error message and some
context (and it clearly doesn't belong to these lists).

Yes. In GDA, I've developed a library to easy access to Database
objects a la Django. Is developed in Vala and provides GObject
Introspection bindings.
From Python I can access to GDA and GdaData (my library) using
"from gi.repositoy import GDA, GdaData", and use to access database
objects.
But I've tried apache mod_python, and after configure a site with
that, I just found that a query data, can't be returned to be
displayed in a routing that is called to handle a request. I call a
function when a requests with a path in the URL, it calls a
function using my library from GObject Introspection, but when
returns the data to the caller it simple don't shows any value.

It’s a bit unclear to me, what exactly you want to achieve.
What I understand (correct me if I’m wrong) is that you wrote a
library in Vala, which uses GDA, and you want to use your library
from a web app written in Python.
If I’m right, then all you have to do is to create some GObject
Introspection files for your library, so in Python you can simply
use the form »from gi.repository import YourLibrary«. How to do
this is beyond my knowledge, as I’m pretty beginner with Vala
itself; you may want to go directly to the Vala mailing list, or
their IRC channel.

Ar there any one using this way?
If you ask why? Its because I'm developing Vala libraries and I
would like to use them in web applications.
