Re: Adding more data to Generic Views

Hi,

I just started to convert my small hobby-project into class-based views and struggled with similar things (but with a ListView instead).

The person object is in the context dictionary, so you need to refer to it by context['person'].

More generally, it is instructive to print context, kwargs and self.kwargs inside the get_context_data method. That would give you the information you need. It took me some time to realize that url-captured parameters are available in self.kwargs.

Hola,

I'm confused about adding extra content to a class based Generic View. I've read

the docs at file:///home/datakid/src/django-docs/topics/class-based-views.html 

and have written the code accordingly. 

I have Person, Certificate, Job and Compensation objects. The last three all 

have an FK (or M2M) back to a (or some) Person(s).

My DetailView subclass (which I've put in views.py - is there a better or more

correct place for it?)

class PersonDetailView(DetailView):

    context_object_name = "person"

    model = Person

    def get_context_data(self,**kwargs):

        #Call the base implementation first to get a context

        context = super(PersonDetailView, self).get_context_data(**kwargs)

        #Add in a querysets

        context['job_list'] = Vacancy.complete.all()

        context['certificate_list'] = Certificate.objects.all()

        context['claim_list'] = Compensation.objects.all()

        return context

But I don't want the full list of Vacancies, Certificates or Claims - I just 

want those that are linked to the person - how can I filter by these? I've tried

.filter(self.get_id)

.filter(self.request.get_id)

.filter(self.person.get_id)

.filter(self.request.person.get_id)

.filter(applicants__get_id__exact=self.get_id) (in the case of Vacancy) etc

How do I filter by the person object that is already in the context?

I know the answer is simple - I should wait until tomorrow when my brain is 

fresher, but I want to finish this off tonight if possible.

Of course, the other thing that I can't help but thinking is that at this point, the non-generic-view method of urls/views might be a simpler way to go. While Generic Views are quite versatile,  is there a point at which they are considered to restricting?
