无法在模板中打印从视图功能返回的字典

Question

my view function returns a dictionary . I am trying to print the dictionary in my template. But nothing gets printed. It prints application/json instead of printing the values of dictionary .Can anyone help me solve this ?

def display(request):
if request.method == 'POST' or 'GET' :
    form = displayForm(request.POST or request.GET or None)
    val = request.POST.get('ser')
    form.fields['ser'].choices = [(val, val)]
    if form.is_valid():

        #context = RequestContext(request)
        grp = request.POST.get('grp_name')
        env1 = request.POST.get('env')
        serv = request.POST.get('ser')

        res ={} 
        res = check_expiry(request.GET,grp,env1,serv)

        print res 

        return render_to_response('certificate_expiry/display.html', {'form':form ,'res': res} )
else:
    form = UrlForm()

return render(request,'certificate_expiry/display.html',{'form':form})


 ## the html template 
 <div>
   {% for k,v in res.iteritems %}

         <li> {{ v }} </li>


  {% endfor %}
  </div>

Answer 1

In django template you use .items to access dictionary:

  {% for k,v in res.items %}
         <li> {{ v }} </li>
  {% endfor %}

Answer 2

You aren't passing res to the template response if form.is_valid() returns false. Instead you are only passing the form back to the template.

This is most likely why you aren't seeing your iteration get printed out.

You need .items rather than .iteritems in django templates.

Also, you can try changing your render_to_response function into a render function. (I prefer the latter).

return render(request, 'certificate_expiry/display.html', {'form':form,'res':res})
