Django Type Error - render to string got multiple values for keyword argument context_instance

问题

I'm new in django and I collect all the static and templates from the admin site to customize. Now I'm trying to render a queryset to the change_list.html from the admin site.
view.py

def person_list(request):
    if request.method == 'GET':
        qs = Person.objects.all()
        return render(request, 'admin/change_list.html', {'app_label': 'clients'}, {'results_list':qs})
   else:
       return render(request, 'admin/change_list.html')

And I'm getting this type error:

render_to_string() got multiple values for keyword argument 'context_instance'

Here is the full traceback:

Can you help me solve this? Thanks!

回答1:

i think you are using the admin module to do something it can't... what are you trying to do?

i guess you'd better try to do it without the admin. often customizing it is more painful than implementing the code yourself, because of its complexity!

in particular, the {% result_list cl %} tag you see in the admin tamplate change_list.html (line 91) is not a template varible (that you are trying to pass in the context) but a template custom tag! whatever you want to do, this is the wrong path ;)

回答2:

Try send values in one dictionary

{'app_label': 'clients', 'results_list':qs}
