Ok; so you want to use a template context of:
context = TemplateContext({
'myday' : Day.objects.get(date=date.today())
})
with a template of:
{% for concert in myday %}
{{ concert.title}} {{ concert.description }}
{% endfor %}
{% for meeting in myday %}
{{ meeting.title}} {{ meeting.description }}
{% endfor %}
The alternative is using a context of:
context = TemplateContext({
'todaysConcerts': Concerts.objects.filter(date=date.today()),
'todaysMeetings': Meetings.objects.filter(date=date.today())
})
with a template of
{% for concert in todaysConcerts %}
{{ concert.title}} {{ concert.description }}
{% endfor %}
{% for meeting in todaysMeetings %}
{{ meeting.title}} {{ meeting.description }}
{% endfor %}
I don't see why the former is in any way preferable to the latter,
especially if you have to mess around with optimizing the Date model.
If your problem is the repeated query clause in the context, remember all
the fancy things you can do with dictionaries and the ** operator:
query = {
'date':date.today()
}
context = TemplateContext({
'todaysConcerts': Concerts.objects.filter(**query),
'todaysMeetings': Meetings.objects.filter(**query)
})
You could even go completely dynamic:
context = TemplateContext(
dict([('todays'+model.name, model.objects.filter(date=date.today())) for
model in [Concerts, Meetings]])
)
