我在 views.py 中上课：

C:\windows\system32\inetsrv\appcmd.exe set apppool AppPOOLName /cpu.limit:20000 /cpu.action:KillW3wp /cpu.resetInterval:00:01:00

我想将对象添加到字段中，但是当我尝试像这样添加时：

class PostCreateView(LoginRequiredMixin,CreateView):
    model = Post
    fields = ['title','content',]

    def form_valid(self,form):
        form.instance.author = self.request.user
        return super().form_valid(form)

调试器发送如下错误日志：

fields = ['title','category']

在django博客中创建帖子时，我需要一个额外的列来添加FieldError at /post/new/ Unknown field(s) (category) specified for Post 字段。

这是 blog_category.html

category

models.py ：

{% extends 'blog/base.html' %}
{% block content %}
  <h1 class='mb-3'>Category: {{ category | title }}</h1>
  {% for post in posts %}
  <article class="media content-section">
    <img class="rounded-circle article-img" src="{{ post.author.profile.image.url }}" alt="">
    <div class="media-body">
      <div class="article-metadata">
        <a class="mr-2 author_title" href="{% url 'user-posts' post.author.username %}">@{{ post.author }}</a>
        <small class="text-muted">{{ post.date_posted|date:"N d,Y" }}</small>
        <div>
        <small class="text-muted">
          Categories:&nbsp;
          {% for category in post.categories.all %}
          <a href="{% url 'blog_category' category.name %}">
            {{ category.name }}
          </a>&nbsp;
          {% endfor %}
        </small>
        </div>
      </div>
      <h2><a class="article-title" href="{% url 'post-detail' post.id %}">{{ post.title }}</a></h2>
      <p class="article-content">{{ post.content|slice:200 }}...</p>
    </div>
  </article>

  {% endfor %}
{% endblock content %}

我的 post_form.html ：

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse

class Post(models.Model):
    title = models.CharField(max_length=200)
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now)
    author = models.ForeignKey(User,on_delete=models.CASCADE)
    categories = models.ManyToManyField('Category',related_name='posts')
    image = models.ImageField(upload_to='images',default="images/None/no-img.jpg")



    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('post-detail',kwargs={'pk': self.pk})


class Category(models.Model):
    name = models.CharField(max_length=20)

主要目标是：

在views.py->中创建{% extends 'blog/base.html' %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4">Blog Post</legend> {{ form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit">Post</button> </div> </form> </div> {% endblock content %} 字段->按下“发布”后，此字段应将内容推送到django管理面板，并将类别添加到帖子中（作为标题和内容添加）。

如果有人有现成的解决方案或知道如何解决此问题，我将非常高兴。
