Question

我是Django新手。

我想限制用户使用特定域名（例如@ gmail.com）注册我的Django网站，但是如何在我的注册表单中自定义EmailField呢？

仅供参考，这是我的代码。

forms.py

class RegistrationForm(ModelForm):
    username = forms.CharField(label=(u'User Name'))
    email = forms.EmailField(label = (u'Email Adress'))


    class Meta:
        model = UserProfile
        exclude = ('user',)

register.html

{% extends "base.html" %}
{% block content %}
<form action = "" method ="post">
{% csrf_token%}
{% if form.errors %}  <p>Please correct the following fields</p> {% endif %}
<div class  ="register_div">
    {% if form.username.errors %}<p class="error">{{ form.username.errors }}</p>{% endif %}
    <p><label for="username"{% if form.username.errors %} class="error"{% endif %}>Username:</label></p>
    <p>{{ form.username }}</p>
</div>
<div class  ="register_div">
    {% if form.email.errors %}<p class = "error">{{ form.email.errors }}</p>{% endif %}
     <p><label for ="email"{% if form.email.errors %} class="error"{% endif %}>Email:<label><p>
    <p>{{ form.email }}</p>
</div>

<p><input type="submit" alt="register" /></p>
</form>
{% endblock %}

Answer 1

您可以为表单编写自己的清理函数：

class RegistrationForm(ModelForm):
    username = forms.CharField(label=(u'User Name'))
    email = forms.EmailField(label = (u'Email Adress'))

    def clean_email(self):
        data = self.cleaned_data['email']
        if "@gmail.com" not in data:   # any check you need
            raise forms.ValidationError("Must be a gmail address")
        return data

    class Meta:
        model = UserProfile
        exclude = ('user',)

您可以通过HTML5输入标记属性（模式）实现相同的目标。比如你的域名是foo.com，那么代码将是：

<input id="email" type="email" pattern="[a-z.]*[@]\bfoo.com" required>

您还可以使用DOM元素的setCustomValidity更改错误消息。

document.getElementById('email').setCustomValidity("Please use an @foo.com email address.");
