如何檢查單選按鈕之一是在視圖中選擇？

Question

它應該是很簡單的，但我無法找到我怎麼能檢查的單選按鈕中的一個選擇

class ViewSettingsForm (forms.Form): 

    CHOICES=[('select1','select 1',), 
     ('select2','select 2'), ('select3','select 3')] 

    like = forms.ChoiceField(choices=CHOICES, widget=forms.RadioSelect()) 
    name = forms.ChoiceField() 


def view_settings (request) : 
    owner = request.user 
    if request.POST: 
      # ??? How to check that something was selected 
    else : 
     form = ViewSettingsForm()

試試這個：

try: 
    print request.POST.get('like') 
except: 
    print "nothing was selected"
