MyModel私は以下のモデルを持っています。でフォームを送信すると、値が例外のat/を受け取りました。デバッガーによると、エラーは次の行にあります。KeyError/addnameviews.form_add
name = request.session['name']
なにが問題ですか？
myapp/models.py
class MyModel(models.Model):
name = models.CharField(max_length=50)
myapp/forms.py
class MyModelForm(ModelForm):
class Meta:
model = MyModel
myapp/urls.py
urlpatterns = patterns('myapp.views',
url(r'^$', 'main'),
url(r'^add/', 'form_add'),
)
myapp/views.py
def main(request):
if request.method == 'POST':
form = MyModelForm(request.POST)
if form.is_valid():
name = form.cleaned_data['name']
return HttpResponseRedirect('/add') # Redirect after POST
else:
form = MyModelForm()
args = {}
args['form'] = form
return render(request, 'main.html', args)
def form_add(request):
args = {}
name = request.session['name']
args['name'] = name
mm = MyModel(name=name)
mm.save()
return render(request, 'add.html', args)

main関数の保存MyModelを次のように書き直しましたrequest.session['name']。
def main(request):
if request.method == 'POST':
form = MyModelForm(request.POST)
if form.is_valid():
name = form.cleaned_data['name']
# I added the lines below to create MyModel and request
request.session['name'] = name
mm = MyModel.objects.create(name=name)
mm.save()
# the indentation was wrong
return HttpResponseRedirect('/add') # Redirect after POST
else:
form = MyModelForm()
# the indentation was wrong
args = {}
args['form'] = form
return render(request, 'main.html', args)
