MultiValueDictKeyError at /signup

如何解决MultiValueDictKeyError at /signup

尝试为每个 HTML 输入元素添加一个名称属性。例子：

<input type="text" id="uname" name="uname" placeholder="Create a username", required>
<input type="text" id="fname" name="fname" placeholder="Enter First Name", required>
...
...
...

当前的问题是找不到密钥，打印出来request.POST，它可能是空的。

解决方法

我正在 django 中创建登录页面，但在 /signup 处遇到 MultiValueDictKeyError 问题下面是 views.py ‘’‘

from django.shortcuts import render,redirect
from django.http import HttpResponse
from django.contrib.auth.models import User
from django.contrib import messages


def home(request):
    return render(request,"authentication/index.html")


def signup(request):
    if request.method == "POST":
        uname = request.POST['uname']
        fname =request.POST['fname']
        lname = request.POST['lname']
        email = request.POST['email']
        pass1 = request.POST['pass1']
        pass2 = request.POST['pass2']

        myuser = User.objects.create_user(uname,email,pass1)
        myuser.first_name = fname
        myuser.last_name = lname

        myuser.save()

        messages.success(request,"Your account has been successfully created.")

        return redirect('signin')

    return render(request,"authentication/signup.html")


def signin(request):
    return render(request,"authentication/signin.html")


def signout(request):
    pass

’‘’

下面是signup.html ‘’‘

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Database</title>
</head>
<body>

        <h3>Sign Up</h3>
        <form action="/signup" method="post">
            {% csrf_token %}
            <label for="">Username</label>
            <input type="text" id="uname" placeholder="Create a username",Required>
            <br>

            <label for="">First Name</label>
            <input type="text" id="fname" placeholder="Enter First Name",Required>
            <br>

            <label for="">Last Name</label>
            <input type="text" id="lname" placeholder="Enter Last name",Required>
            <br>

            <label for="">Email</label>
            <input type="email" id="email" placeholder="Enter Email address",Required>
            <br>

            <label for="">Password</label>
            <input type="password" id="pass1" placeholder="Create a Password",Required>
            <br>

            <label for="">Confirm your password</label>
            <input type="password" id="pass2" placeholder="Confirm your password",Required>
            <br>

            <button type="submit">Sign Up</button>

        </form>

</body>
</html>

’‘’
