Question

我使用主页构建了两个应用程序，用于普通博客的应用程序博客和用于异步消息传递的应用程序twit。表单已确认为已发布且也有效，但数据库未更新。

我的第一个猜测是用户和内容没有关联，并且尝试了很多徒劳的方法，希望能得到你们的帮助，谢谢

以下是代码：

主页：

<form method="POST" id="twit" action={% url 'twit:create' %}>
    {% csrf_token %}
    {{form|crispy}}
    <div class="form-group">
        <button type="submit">Post</button>
    </div>
</form>

博客/观看次数：

def home_view(request):
    form = TwitForm()
    post_list = Post.objects.all()
    context = {
        'form': form,
        'post_list':post_list,
    }
    return render(request, 'blog/blog_list.html', context)

twit /视图：

def twit_create(request):
    if request.method == 'POST':
        form = TwitForm(request.POST or None, instance=request.user)
        print('inside post')
        if form.is_valid():
            print('inside valid')
            form.save()
            return redirect('blog:home')
    else:
        print('inside else')
        form = TwitForm(instance=request.user)
    post_list = Post.objects.all()
    context = {
        'post_list': post_list,
        'form': form,
    }
    return render(request, 'blog/blog_list.html', context)

from django import forms
from .models import Twit

class TwitForm(forms.ModelForm):
    class Meta:
        model = Twit
        fields = ['message']

twit /模型

from django.db import models
from django.contrib.auth.models import User 

class Twit(models.Model):
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    message = models.TextField(max_length=100)
    published = models.DateTimeField(auto_now=True)

    class Meta:
        verbose_name_plural = 'twits'
        ordering = ['-published']
        verbose_name = 'twit'

    def __str__(self):
        return self.message[:10]

twit /表格

from django import forms
from .models import Twit

class TwitForm(forms.ModelForm):
    class Meta:
        model = Twit
        fields = ['message']

终端：

inside post
inside valid
[07/Feb/2019 21:23:21] "POST /twit/create/ HTTP/1.1" 302 0
[07/Feb/2019 21:23:21] "GET / HTTP/1.1" 200 10548
[07/Feb/2019 21:37:33] "GET / HTTP/1.1" 200 10722

表单有效，但无法保存到后端
