Question

我认为这应该很简单，但我似乎无法找到我正在寻找的答案。我正在基于模板中的外键/下拉设置会话变量。会话变量保存为主键而不是字段名称。我该如何改变？

模型：

class Verbs(models.Model):
    verb = models.CharField(max_length=20)

    def __unicode__(self):
        return self.verb

class MyVerbs(models.Model):
    verb = models.ForeignKey(Verbs)

形式：

class MyVerbForm(forms.ModelForm):

class Meta: 
    model = MyVerbs

的观点：

def TestSession(request):
request.session['myverb'] = ''
if request.method == 'POST':
    form = MyVerbForm(request.POST)
    if form.is_valid():
        myvariable = form.cleaned_data['verb']

    #myvariable = request.POST.get('verb', '')
    request.session['myverb'] = myvariable
    return HttpResponseRedirect('/')
else:
    form = MyVerbForm(request.POST)
    context = {'form': form}
    return render_to_response('test.html', context, context_instance=RequestContext(request))

def会话（请求）： myvariable = request.session ['myverb'] context = {'myvariable'：myvariable} return render_to_response（'base.html'，context，context_instance = RequestContext（request））

您应该致电form.is_valid()，然后从form.cleaned_data而不是request.POST获取价值。

在Django中设置外键的会话变量：需要字段名而不是主键
