> Very nice. How hard was it building the extension tag?
Very easy. In fact I did the extension tag in my second day of using
albatross.
Since Gregory might have use here is the alx_sql.py code (the database
connection is made in globals.py):
..........................................
import albatross, MySQLdb
from globals import db
class Sql(albatross.EmptyTag):
name = 'alx-sql'
def __init__(self, ctx, filename, line_num, dict):
self.db_cursor = db.cursor()
albatross.EmptyTag.__init__(self, ctx, filename, line_num, dict)
def to_html(self, ctx):
stmt = self.get_attrib('stmt')
args = self.get_attrib('args')
ctx.locals.db_cursor = self.db_cursor
try:
if args is None:
ctx.locals.db_cursor.execute(stmt)
else:
ctx.locals.db_cursor.execute(stmt, eval(args,
ctx.locals.__dict__))
except MySQLdb.DatabaseError, errstr:
self.raise_error("Database Error: " + str(errstr))
...........................................
Not a lot, but gets the job done. I used MySQLdb, but should work with
any DB API 2.0 driver without much change.
