How to add initial default value in Django's EmailField()

Question

I have the following django scheme:

forms.py

from django import forms

class ContactForm(forms.Form):
    name_param        = forms.CharField()
    email_param       = forms.EmailField()
    message_param     = forms.CharField(widget=forms.Textarea)
    recaptcha_param   = ReCaptchaField()

My question is:

I'd like to implement something like this. Also we'd like to enable direct overwrite-as-we-type on the default value.

Answer 1

您可以在email_param字段中添加占位符属性。所以你的forms.py将是：

from django import forms

class ContactForm(forms.Form):
    name_param        = forms.CharField()
    email_param       = forms.EmailField(widget=forms.EmailInput({'placeholder': 'test@example.com'}))
    message_param     = forms.CharField(widget=forms.Textarea)
    recaptcha_param   = ReCaptchaField()

Answer 2

那只是HTML

<input type="email" placeholder="This is used to contact you..." name="email"/>

Answer 3

注意

forms.EmailField（）

不会将小部件作为参数。

你可以这样做的方式可能是

models.EmailField（max_length = 255，默认='你默认值或者是example@email.com'）

这比html解决方案更强大，为您提供了在数据库上管理它的方法
