hello. get_queryset question

[Víctor Suárez]

Hello all,
as it's my first post, if any django developer around, nice work! I appreciate the package, I've been able to pull a small project I had in mind for long, very easily with this.

I am needing help with one part of the Views.
I'm using a generic.ListView, nothing fancy, but then, as the list can get really big, I am trying to create a search box for it. I've read around of using get method, which is fine for me, but when I get into the view, and I override get_queryset I never find the kwargs dictionary to work the search.
I also tried overriding get method but I didn't find the args either.
I found a code on stackoverflow which seems to be what I am looking for, but it always return all(), even when django-debug-toolbar tells me the request was made with get data, the View doesn't show up any kwargs

Do anyone has a suggestion? related to both why I am not getting the kwargs and what's the best way to implement a search box on a ListView?
consider I am new to this
Thanks!
regards

    def get_queryset(self):
        try:
            name = self.kwargs['name']
        except:
            name = ''
        if (name != ''):
            object_list = self.model.objects.filter(name__icontains = name)
        else:
            object_list = self.model.objects.all()
        return object_list

Try with

self.request.GET['name']

Yes, this is is what you want. 

Normally, though, I've seen it written as self.request.GET.get('name'). This calls the .get() dict method on the GET attribute of the request, which will return None in the event that 'name' does not exist. Calling the member directly above will throw an exception if it doesn't exist, which will likely be the case on the first page load with no filter, unless you always call that view with a URL containing name=, hard to do in Django. 

Also keep in mind that a key may contain multiple values (although it probably won't with a simple search field), you can call .getlist(key) or call .get() multiple times to get all of the values. See the explanation of the GET QueryDict object here:

https://docs.djangoproject.com/en/dev/ref/request-response/#django.http.HttpRequest.GET

Self.kwargs refers to the keyword arguments to the view itself within Django, usually consisting of the request and captured URL parameters from your urls.py, among other things.

Admittedly, that's not explicitly spelled out anywhere in the docs AFAIK. 

As an FYI, there are also 3rd party packages that can handle this functionality for you, such as django-filter.

Thank you very much

man I can like this framework like a lot.... I end up with:

class MyModel(ListView):
...
        q = self.request.GET.get('q',default='')
        country = self.request.GET.get('country',default='')
        owner = self.request.GET.get('owner',default='')
        self.queryset = CellSite.objects.filter(
                                                 Q(name__icontains=q) |
                                                 Q(code__icontains=q),
                                                 country__istartswith=country,
                                                 owner__istartswith=owner,
                                                 active__exact=True,
                                                    )
        response = super(MyModelListView, self).get(request, *args, **kwargs)
        return response
