Re: How to handle values_list?

Thanks to Leonardo, Daniel and Charly this issue is resolved! Each of your comments helped me.

I changed my views.py file filter statement:

FROM: name = Name.objects.filter(pk=my_number).values_list('city', flat=True)

TO: name = Name.objects.get(pk=number).name

And in my template I have the same code:

{{ name|safe }}

And now Green shows on my web page instead of [u'Green']!

Andrew, I think that the view is missing something:

def enter_name(request):

    my_number = request.user.number

    name = Name.objects.filter(pk=my_number).values_list('city', flat=True)

    data = {...}

    return render_to_response('template.html', data, context_instance=RequestContext(request))

where data is a dictionary with the values you want to be available in your template. So, for the template you posted, you could write

    data = {'name':name[0]}

Here, you need to decide what you need to pass: why do you use filter() instead of get()? Do you need just one value or multiple?

If you need to pass a list to the template just fill the dictionary accordingly, but follow Daniel's advice when rendering the list in the template.
