With the following code below, There is an error saying
File "/home/user/web_pro/info/views.py", line 184, in headerview,
raise TypeError("%r is not JSON serializable" % (o,))
TypeError: <lastname: jerry> is not JSON serializable
In the models code
header(models.Model):
firstname = models.ForeignKey(Firstname)
lastname = models.ForeignKey(Lastname)
In the views code
headerview(request):
header = header.objects.filter(created_by=my_id).order_by(order_by)[offset:limit]
l_array = []
l_array_obj = []
for obj in header:
l_array_obj = [obj.title, obj.lastname ,obj.firstname ]
l_array.append(l_array_obj)
dictionary_l.update({'Data': l_array}) ;
return HttpResponse(simplejson.dumps(dictionary_l), mimetype='application/javascript')
what is this error and how to resolve this?
thanks..
The quick read is that obj.lastname is a Lastname model not a String. You probably need to say something like:
l_array_obj = [..., obj.lastname.value, .... ]
to get the string value, rather than the Model object.
