that the popup opens but i get a:
TypeError at /popadd/topics/
'str' object is not callable
Request Method: GET
Request URL: http://127.0.0.1:8000/de/popadd/topics/?_popup=1
Exception Type: TypeError
Exception Value:
'str' object is not callable
Exception Location:
/home/pepe/DEV/FSlabs/parts/django/django/core/handlers/base.py in
get_response, line 92
my views.projects ProjectForm:
class ProjectForm(ModelForm):
topics = ModelMultipleChoiceField(Topic.objects,
required=False, widget=MultipleSelectWithPop)
technologies = ModelMultipleChoiceField(Technology.objects,
required=False, widget=MultipleSelectWithPop)
class Meta:
model = Project
exclude = ['author']
my views.handlePopAdd.py :
from django.utils.html import escape
from django.contrib.auth.decorators import login_required
from myapp.views.technologies import TechnologyForm
from myapp.views.topics import TopicForm
def handlePopAdd(request, addForm, field):
if request.method == "POST":
form = addForm(request.POST)
if form.is_valid():
try:
newObject = form.save()
except forms.ValidationError, error:
newObject = None
if newObject:
return HttpResponse('<script
type="text/javascript">opener.dismissAddAnotherPopup(window, "%s",
"%s");</script>' % \
(escape(newObject._get_pk_val()),
escape(newObject)))
else:
form = addForm()
pageContext = {'form': form, 'field': field}
return render_to_response("add/popadd.html", pageContext)
@login_required
def newTopic(request):
return handlePopAdd(request, TopicForm, 'topics')
@login_required
def newTechnology(request):
return handlePopAdd(request, TechnologyForm, 'technologies')
