I´m having 2 models:
class CinemaProgram(models.Model):
cinema = models.ForeignKey(Cinema)
movie = models.ForeignKey(Movie, raw_id_admin=True)
....
class CinemaProgramDate(models.Model):
cinemaprogram = models.ForeignKey(CinemaProgram,
edit_inline=models.TABULAR, num_in_admin=20, max_num_in_admin=200,
num_extra_on_change=100)
screening_date = models.DateField('Screening Date', core=True)
screening_time = models.TimeField('Screening Time', core=True)
add_screen = models.CharField('Screen', maxlength=50,
blank=True, null=True)
....
for the template, I´d like to have something like this:
{% for cinema in cinema_list %}
{{ cinema }}
{% for screens in cinema %}
{{ screen }}
{% for screening_time in screens %}
{{ screening_time }}
{% endfor %}
{% endfor %}
{% endfor %}
Now, my question is: how do I get/construct the dict for this template?
Note: The output should be:
Movie XXX on Date YYY is shown in these Cinemas:
Cinema 1
Screen 1: 18:00 20:00 23:00
Screen 2: 20:00
Cinema 2
Screen 1: 18:30
Cinema 3
Screen 1: 20:00
Screen 4: 22:30
I don´t really know if I need a custom manager or a custom method or
if I have to refactor my models.
any hints are really appreciated (I´ve been working on this one for a
couple of days and it´s getting frustrating ...).
so far, I´ve been using this one:
movie_list = CinemaProgramDate.objects.filter
(cinemaprogram__cinema__place_state__slug=state, screening_date=date,
cinemaprogram__movie=movie_id).select_related().order_by
('cinemas_cinema.name', 'add_screen')
with what I get here, I´m not able to do the template accordingly
(because I´d need an {% ifnotchanged %} which doesn´t exist).
well, enough for now - I hope somebody has the time to help me with
this.
Thanks,
patrick
