如何將 attr 傳遞給 forms.CharField

Question

我想將一些 Html attr 傳遞給由脆皮生成的表單字段

我嘗試在 django 2.2.3 中使用此代碼

class AddForm(forms.Form):
    todo = forms.CharField(max_length=128, attrs={'placeholder':'What do you want to do?'})

但我有一個錯誤

    from .forms import AddForm
  File "C:\Users\HP\django_project\todo\forms.py", line 4, in <module>
    class AddForm(forms.Form):
  File "C:\Users\HP\django_project\todo\forms.py", line 5, in AddForm
    todo = forms.CharField(max_length=128, attrs={'placeholder':'What do you want to do?'})
  File "C:\Users\HP\AppData\Local\Programs\Python\Python37\lib\site-packages\django\forms\fields.py", line 214, in __init__
    super().__init__(**kwargs)
TypeError: __init__() got an unexpected keyword argument 'attrs'

Answer 1

attrs是小部件的參數，而不是字段。

todo = forms.CharField(max_length=128, widget=forms.TextInput(attrs={'placeholder':'What do you want to do?'}))
