Question

我有一个Django项目，其中尝试“更新”（单击按钮）会导致以下错误：

CSRF verification failed. Request aborted.

Help
Reason given for failure:

    CSRF token missing or incorrect.

我查看了各种问题和答案，这些建议表明添加RequestContext是解决方案，但是我尝试了一些针对我的代码量身定制的解决方案，但是仍然无法使其正常工作。

原始代码 views.py 在下面

#USERS (register) view.py
from django.shortcuts import render,redirect
from django.contrib.auth.forms import UserCreationForm
from django.contrib import messages #this allows us flash messages for testing
from django.contrib.auth.decorators import login_required
from .forms import UserRegisterForm
from .forms import UserUpdateForm
from .forms import ProfileUpdateForm

from django.contrib.auth.decorators import login_required

def register(request):
    if request.method =='POST':
        #this UserRegisterForm is created in forms.py and inherits from UserCreationForm (the ready made form)
        form = UserRegisterForm(request.POST) #create a form that has the data that was in request.POST
        if form.is_valid(): #is the form valid (do you have a username like this already, passwords match?
            form.save()
            username = form.cleaned_data.get('username')
            messages.success(request,f'Account created for {username}, you can now login.')
            return redirect('login')

    else:
        form =UserRegisterForm() #if the form input is invalid, render the empty form again


    return render(request, 'users/register.html',{'form':form})


@login_required #this is a decorator (adds functionality to an existing function)
def profile(request):
    if request.method =='POST':
        u_form =UserUpdateForm(request.POST,instance=request.user)
        p_form =ProfileUpdateForm(request.POST, request.FILES,instance=request.user.profile)

        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request,f'Your Account has been directed')
            return redirect('profile')

    else:   
        u_form =UserUpdateForm(instance=request.user)
        p_form =ProfileUpdateForm(instance=request.user.profile)


    context={
            'u_form': u_form,
            'p_form': p_form
        }

    return render(request,'users/profile.html',context)

如上所述，我也尝试过：

return render(request,'users/profile.html',context_instance=RequestContext(request))

我还尝试将以下内容添加到导入中

from django.shortcuts import get_object_or_404, render,redirect

注意：我不希望尝试使用“删除中间件”替代方法。

下面是 profile.html 文件代码，据我所知，我正确地包含了CSRF令牌：

{% extends "socialmedia/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
    <div class="content-section">
      <div class="media">
        <img class="rounded-circle account-img" src="{{ user.profile.image.url }}">
        <div class="media-body">
          <h2 class="account-heading">{{ user.username }}</h2>
          <p class="text-secondary">{{ user.email }}</p>
        </div>
      </div>
     <form method="POST" enctype="multipart/form-data>
        {% csrf_token %}
        <fieldset class="form-group">
            <legend class="border-bottom mb-4">Profile Information</legend>
            {{u_form|crispy}}
            {{p_form|crispy}}
        </fieldset>
        <div class="form-group">
            <button class="btn btn-outline-info" type="submit">Update....</button>
        </div>
    </form>
   </div>
{% endblock content %}

最后，关于上下文，这里是 forms.py

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
from .models import Profile

class UserRegisterForm(UserCreationForm): #form that inherits from the usercreationform
    email = forms.EmailField()

    class Meta: 
        model = User 
        #when this form validates it creates a new user
        #type the fields to be shown on your form, in that order.
        fields = ['username','email','password1','password2']   

class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()

    class Meta: 
        model = User 
        fields = ['username','email']

class ProfileUpdateForm(forms.ModelForm):
    class Meta:
        model= Profile
        fields=['image']

问题：是什么导致错误，我需要在代码中添加/更改内容吗？

我还遇到了一个关于StackOverflow的回答，它说：“问题是您没有返回结果。请记住，该视图是一个函数。您需要返回render_to_response（...），而不仅仅是调用它（还为什么通过删除CSRF却没有返回HttpResponse错误）“ ....有人可以在我的上下文中解释这一点吗？我也不明白这意味着什么或如何实现。

它似乎应该可以工作，但是我注意到您似乎在此处末尾缺少引号

 <form method="POST" enctype="multipart/form-data>

CSRF验证在Django项目更新中失败，并且RequestContext解决方案不起作用
