django - 如何将类属性添加到 ModelForm

Question

我有模特:

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modelForm:

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

如何更改 TestPoljaForm添加class归属于 <input>标记？

如何添加小部件？

Answer 1

你可以在 __init__ 表单方法中做到:

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'
