How do I add a placeholder on a CharField in Django?

Question

Take this very simple form for example:

class SearchForm(Form):
    q = forms.CharField(label=\'search\')

This gets rendered in the templat

Answer 1

After looking at your method, I used this method to solve it.

class Register(forms.Form):
    username = forms.CharField(label='用户名', max_length=32)
    email = forms.EmailField(label='邮箱', max_length=64)
    password = forms.CharField(label="密码", min_length=6, max_length=16)
    captcha = forms.CharField(label="验证码", max_length=4)

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    for field_name in self.fields:
        field = self.fields.get(field_name)
        self.fields[field_name].widget.attrs.update({
            "placeholder": field.label,
            'class': "input-control"
        })
