Getting context of parent in Foreign Key - Django - django

Question

This is supposed to be really simple and it is in the documents. I am trying to get the context of a ListView. For example:
"We can also add the publisher into the context at the same time, so we can use it in the template http://docs.djangoproject.com/en/1.3/topics/class-based-views/#dynamic-filtering/:
class IssuesByTitleView(ListView):
context_object_name = "issue_list"
def get_queryset(self):
self.title = get_object_or_404(Title, slug=self.kwargs['title_slug'])
return Issue.objects.filter(title=self.title).order_by('-number')
My models.py look something like this:
class Title(models.Model):
CATEGORY_CHOICES = (
('Ongoing', 'Ongoing'),
('Ongoing - Canceled', 'Ongoing - Canceled'),
('Limited Series', 'Limited Series'),
('One-shot', 'One-shot'),
('Other', 'Other'),
)
title = models.CharField(max_length=64)
vol = models.IntegerField(blank=True, null=True, max_length=3)
year = models.CharField(blank=True, null=True, max_length=20, help_text="Ex) 1980 - present, 1980 - 1989.")
category = models.CharField(max_length=30, choices=CATEGORY_CHOICES)
is_current = models.BooleanField(help_text="Check if the title is being published where Emma makes regular appearances.")
slug = models.SlugField()
class Meta:
ordering = ['title']
def get_absolute_url(self):
return "/titles/%s" % self.slug
def __unicode__(self):
return self.title
class Issue(models.Model):
CATEGORY_CHOICES = (
('Major', 'Major'),
('Minor', 'Minor'),
('Cameo', 'Cameo'),
('Other', 'Other'),
)
title = models.ForeignKey(Title)
number = models.IntegerField(help_text="Do not include the '#'.")
.........
Views.py:
class IssuesByTitleView(ListView):
context_object_name = "issue_list"
def get_queryset(self):
self.title = get_object_or_404(Title, slug=self.kwargs['title_slug'])
return Issue.objects.filter(title=self.title).order_by('-number')
def get_context_data(self):
context = super(IssuesByTitleView, self).get_context_data()
context['title'] = self.title
return context
In my list of issues within the Title, I need to return the Title and all the other properties of the Title. That up there does not work and it returns an error:
get_context_data() got an unexpected keyword argument 'object_list'

Answer 1

You should use **kwargs in get_context_data
def get_context_data(self, **kwargs):
context = super(IssuesByTitleView, self).get_context_data(**kwargs)
context['title'] = self.title
return context
