TRAC. Return a javascript variable back to javascript

Question

Is there any way to pass a javascript varialbe during process_request in trac 0.11? The code goes like this:

def process_request(self, req):

    component = req.args.get('component_name')
    milestones = []
    db = self.env.get_db_cnx()
    cursor = db.cursor()
    milestones_sql = "SELECT name FROM milestone WHERE component = '" + component+ "'"
    cursor.execute(milestones_sql)
    milestones = cursor.fetchall()
    milestones = itertools.chain(*milestones)
    db.commit()
    return 'filter.js', {'milestones':json.dumps(list(milestones))}, 'text/plain'

I get arguments, do a SQL query, and want to return result to a script. Not as a string though.

Since Trac 0.12 there is trac.web.chrome.add_script_data, that might serve your need.

I've noticed that too, but upgrade is still in "planned" and the backport wasn't a solution either. However I've found solution that doesn't require additional data passed to the script. Thank you anyway! – konart May 31 '13 at 10:03
