Seriously. Im reading and reading, but cant understand much or i just
dont find good examples.
What i have is model structure like this :
I have language model, which holds website generic data like language
parameter, encoding, website titles, metainfo and so on
Then i have bit more complex poll system with models like:
poll, question, choices and translation.
Translation model is like this :
class Trans(models.Model):
keel = models.ForeignKey(lang) #for knowing to which language this
translation belongs to
content_type = models.ForeignKey(ContentType) # this and 2 lines
below it are for generic relations as good as i understand them
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey()
name= models.CharField(max_length=500) # for the translation itself
def __unicode__(self):
return self.name
Other models are like this :
class Poll(models.Model):
name = generic.GenericRelation(Trans)
pub_date = models.DateTimeField('date published')
active = models.BooleanField()
def __unicode__(self):
return self.name
def was_published_today(self):
return self.pub_date.date() == datetime.date.today()
class Question(models.Model):
TYPE_CHOICES = (
('1', 'single answer'),
('2', 'multiple choices'),
('3', 'Textfield'),
)
poll = models.ForeignKey(Poll)
nr = models.IntegerField()
name = generic.GenericRelation(Trans)
qtype = models.CharField(max_length=1, choices = TYPE_CHOICES)
def __unicode__(self):
return self.name
def get_choices(self):
choices = Choice.objects.filter(Question = self).order_by('id')
if len(choices) == 0:
return []
return choices
class Choice(models.Model):
name = generic.GenericRelation(Trans)
question = models.ForeignKey(Question)
nr = models.IntegerField()
def __unicode__(self):
return self.name
I have other necessary models too, but i think they are irrelevant
here.
The point of it is that, when i change website language (which now
works thanks to fixing urlconf in my previous thread), i get poll,
with all its questions/choices, in different language.
What i have not been able to figure out is how to change admin view in
a way that when i open poll (for adding a new one)it loops through
languages and gives me X fields where to enter poll name (depending on
how many languages the site has).
Poll in admin.py is like this:
class PollAdmin(admin.ModelAdmin):
list_display = ('name', 'pub_date', 'was_published_today')
and when i go to poll section in admin i get field for publishing date
and thats it. As it seems i lack understanding in several areas : how
to set up admin view so i can set necessary fields and how to use
those generic relations and i have even have created models in a way
that i must create them if i want to achieve my goals.
