django - How to read variables added to RequestContext inside class-based generic views? -

-

with regular views, requestcontext variables can accessed request.varname:

def example(request, template_name='stuff_list'):   return render_to_response(template_name,       {'stuff_list': get_list_or_404(stuff, foo=request.debug)},       context_instance=requestcontext(request))

... instead of setting context_instance call function-based generic view direct_to_template1

how read variables added requestcontext inside class-based generic views 2?

for example:

class articlelistview(listview):   template_name = 'stuff_list'   bar = request.debug   # won't work. should use instead?   queryset = get_list_or_404(stuff, foo=bar)

1 replaced class-based templateview anyway.
2 new in django 1.3 , want use them because.

you need use callback — get_queryset() in case — instead of class attributes. class attributes shortcuts when you're controlling options statically, , they're limited pretty simple things. when need more complex, you'll want switch callback instead.

in case, code following should work:

class articlelistview(listview):     template_name = 'stuff_list'      def get_queryset(self):         return get_list_or_404(stuff, foo=self.request.debug)

for more details, see documentation.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
