为什么 django 中的表单无效

Question

为什么 django 中的表单无效！

您好，我不知道为什么我的表格无效！我试过这个

class SignupForm(forms.Form):
    first_name = forms.CharField(required=True, max_length=35)
    last_name = forms.CharField(required=True, max_length=35)
    username = forms.CharField(required=True, max_length=50)
    email = forms.EmailField(required=True)
    password = forms.CharField(required=True, min_length=8, max_length=64)
    confirm_password = forms.CharField(required=True, min_length=8, max_length=64)

模板.html

<form id="signupForm" action="" method="POST" accept-charset="utf-8" class="form" role="form">
    {% csrf_token %}
    <div class="row">
        <div class="col-xs-6 col-md-6">
            <input id="first_name" type="text" autocomplete="off" name="firstname" value="" class="form-control input-lg" placeholder="First Name" />
        </div>
        <div class="col-xs-6 col-md-6">
            <input id="last_name" type="text" autocomplete="off" name="lastname" value="" class="form-control input-lg" placeholder="Last Name"  />
        </div>
    </div>
    <input id="username" type="text" autocomplete="off" name="username" value="" class="form-control input-lg" placeholder="Choose Username" />
    <input id="email" type="text" autocomplete="off" name="email" value="" class="form-control input-lg" placeholder="Your Email" />
    <input id="password" type="password" autocomplete="off" name="password" value="" class="form-control input-lg" placeholder="Password" />
    <input id="confirm_password" type="password" name="confirm_password" value="" class="form-control input-lg" placeholder="Confirm Password" />
    <div class="topmargin active">
        <div class="row" style="display: flex;">
            <div class="col-xs-5 col-md-5">
                <label>I'm </label>
                <select name="month" class = "form-control input-lg">
                    <option value="male">Male</option>
                    <option value="female">Female</option>
                </select>
            </div>
            <br />
            <span class="help-block">By clicking Create my account, you agree to our Terms and that you have read our Data Use Policy, including our Cookie Use.</span>
    <button class="btn btn-block signup-btn" type="submit">Create my account</button>
</form>

我认为这是因为我没有将表单传递给模板，但我不想这样做！它混合了响应式风格命令，欢迎，谢谢

问题就在这里：

<input id="first_name" type="text" autocomplete="off" name="firstname" value="" class="form-control input-lg" placeholder="First Name" />

<input id="last_name" type="text" autocomplete="off" name="lastname" value="" class="form-control input-lg" placeholder="Last Name"  />

在您的表单中，您使用带下划线的名字和姓氏，但在输入时它们不带下划线。

您需要更改输入名称以匹配表单字段：

<input id="first_name" type="text" autocomplete="off" name="first_name" value="" class="form-control input-lg" placeholder="First Name" />

<input id="last_name" type="text" autocomplete="off" name="last_name" value="" class="form-control input-lg" placeholder="Last Name"  />
