一兩個領域應填寫其中的一個

Question

class FooForm(forms.ModelForm): 
    foo_date = forms.CharField(required=True) 
    foo_time = forms.CharField(required=True) 

後，我如何能實現這樣的事情不是必需的。可能嗎？

Answer 1

集required=False爲兩個字段，然後檢查在clean方法的至少一個被填充。

class FooForm(forms.ModelForm): 
    foo_date = forms.CharField(required=False) 
    foo_time = forms.CharField(required=False) 

    def clean(self): 
     cleaned_data = super(FooForm, self).clean() 
     if not (cleaned_data.get('foo_date') or cleaned_data.get('foo_time')): 
      raise forms.ValidationError('Either foo_date or foo_time is required') 
     return cleaned_data
