Django Form -- ChoiceField字段

• ChoiceField
  

  • from django import forms
    from django.forms import fields
    
    class DetailForm(forms.Form):
    
        inp = fields.ChoiceField(
            initial=2,
            choices=((1, 'SH'), (2, 'BJ'))
        )
    

 

• • ChoiceField字段只能返回字符，value_dic = obj.clean()的結果是{'inp': '2'}

     

• TypedChoiceField  -- 帶有類型轉換功能的下拉框

  • from django import forms
    from django.forms import fields
    
    class DetailForm(forms.Form):
    
        inp = fields.TypedChoiceField(
            coerce=lambda x: int(x),
            initial=2,
            choices=((1, 'SH'), (2, 'BJ'))
        )
    

 

• • 經過匿名函數的類型轉換，TypedChoiceField字段返回了數字2，value_dic = obj.clean()的結果是{'inp': 2}

     

• MultipleChoiceField

  • from django import forms
    from django.forms import fields
    
    class DetailForm(forms.Form):
    
        inp = fields.MultipleChoiceField(
            initial=[1, 2],
            choices=((1, 'SH'), (2, 'BJ'))
        )
    

     

  • value_dic = obj.clean()的結果是{'inp': ['1', '2']}

 

• TypedMultipleChoiceField

  • from django import forms
    from django.forms import fields
    
    class DetailForm(forms.Form):
    
        inp = fields.TypedMultipleChoiceField(
            coerce=lambda x: int(x),
            initial=[1, 2],
            choices=((1, 'SH'), (2, 'BJ'))
        )
    

 

• • value_dic = obj.clean()的結果是{'inp': [1, 2]}
