Re: How do I output a variable from Models.py to Detail.html?

This is my Models code and I want to output the contents of variable blackbox to my screen.

1.)  Do I need to write some code in Views.py to transfer my variable "blackbox" from Models to Views to Detail.html?
2.)  Or can I access my variable "blackbox" directly from Detail.html?

#_______________________________________________________________________________

class AltwordManager(models.Manager):
    def dictfetchall2(self, p):
        "Returns all rows from a cursor as a dict."
        desc = p.description
        self.dark = desc
        return [
            dict(zip([col[0] for col in desc], row))
            for row in p.fetchall()
        ]

    def vote_order(self):
        "Returns a 1:M list ordered by votes."
        cursor =  connection.cursor()
        cursor.execute("""
SELECT navi_polls_word.rosword, navi_polls_altword.alt_ros_word, navi_polls_altword.votes
FROM navi_polls_altword INNER JOIN navi_polls_word
ON (navi_polls_altword.rosword_id=navi_polls_word.id)
ORDER BY votes DESC
        """)
        #row = cursor.fetchall()
        #row = dictfetchall(cursor)
        row = AltwordManager.dictfetchall2(self, cursor)
        blackbox = self.dark
        return blackbox

This, like most of your questions, is *really basic stuff* that is well covered by the tutorial.

You should stop trying to write this complex manager (which BTW does not do what a manager is supposed to do) and go back and do the tutorial, which introduces the concepts simply. Then, read the documentation on managers and understand what they are actually for - and stop writing SQL unless you really need it.
