A list directly (see the code fragment below). Since generic.json serializes response._vars, it doesn't care about anything in env. You *could* write a view that accepts a dict with a list (or dict) as a well-known name and serialize that, but it's not what generic.json does. > > Anthony > > On Tuesday, July 30, 2013 10:28:53 AM UTC-4, Matt wrote: > > > On Tuesday, July 30, 2013 10:26:45 AM UTC-4, Jonathan Lundell wrote: > On 30 Jul 2013, at 12:22 AM, Niphlod <nip...@gmail.com> wrote: >> can you explain better what's going on ? the generic json view (as any other >> view) is made to serialize a python object to something (in json's case, a >> json string). >> If you already return a string because your code encodes it already, than >> you don't need any view, because the job the view usually does has been done >> already by your code. > > The explanation isn't quite clear.
