在init方法中设置Django ModelForm中所有字段的属性 [英] Set attribute of all fields in Django ModelForm in init method

问题描述

我有一个Django ModelForm，在其中我以__init__()方法的形式设置了某些表单属性.

I have a Django ModelForm where I set certain form attributes in the form __init__() method.

class MyForm(forms.ModelForm):

    class Meta:
        model = MyModel
        exclude = ['datecreated', 'datemodified']

    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.fields['field1'].widget.attrs['class'] = 'class1'
        self.fields['field2'].widget.attrs['class'] = 'class1'
        self.fields['field3'].widget.attrs['class'] = 'class1'
        # override Google Chrome field error issues making form unfocusable
        self.fields['field1'].required = False
        self.fields['field2'].required = False
        self.fields['field3'].required = False

是否可以设置表格中包含的所有字段的属性，而无需分别为每个字段写self.fields?

Is there away to set attributes of all fields included in the form without writing self.fields for each one individually?

推荐答案

self.fields是普通命令，您可以对其值进行迭代:

self.fields is a normal dict, you can just iterate over its values:

for field in self.fields.values():
    field.widget.attrs['class'] = 'class1'
    field.required = False
