如何類屬性添加到的ModelForm

Question

我有模式：

class TestPolja(models.Model): 
    class Meta: 
     verbose_name = 'Test polja' 

     integerPolje1 = models.IntegerField('integerPolje1') 
     charPolje1 = models.CharField('charPolje1',max_length = 1024) 
     bigint1 = models.BigIntegerField('bigint1',default = 67573737) 
     date = models.DateField('date') 

和的ModelForm：

class TestPoljaForm(ModelForm): 
    class Meta: 
     model = TestPolja 

如何改變TestPoljaForm添加class屬性<input>標籤？

如何添加小部件？

Answer 1

你可以做到這一點在__init__形式方法：

class TestPoljaForm(ModelForm): 
    class Meta: 
     model = TestPolja 

    def __init__(self, *args, **kwargs): 
     super(TestPoljaForm, self).__init__(*args, **kwargs) 

     # for example change class for integerPolje1 
     self.fields['integerPolje1'].widget.attrs['class'] = 'SOMECLASS' 

     # you can iterate all fields here 
     for fname, f in self.fields.items(): 
      f.widget.attrs['class'] = 'SOMECLASS' 

Answer 2

class TestPoljaForm(ModelForm): 
    integerPolje1 = forms.IntegerField(widget=forms.TextInput(attrs={'class': 'myclass'})) 

    class Meta: 
     model = TestPolja
