Python Django博客添加评论文本字段未显示

我使用django的模型和表单向博客应用程序添加评论部分，但是当我尝试向帖子添加评论时，在浏览器中加载时，表单的文本字段将不会显示。只有“提交”按钮和标题可见，没有要提交的文本字段

models.py

from django.db import models
from django.utils import timezone


# Create your models here.
class Post(models.Model):
    author = models.ForeignKey('auth.User', on_delete=models.CASCADE)
    title = models.CharField(max_length=200)
    text = models.TextField()
    created_date = models.DateTimeField(default=timezone.now)
    published_date = models.DateTimeField(blank=True, null=True)

    def publish(self):
        self.published_date = timezone.now()
        self.save()

    def __str__(self):
        return self.title


class Comment(models.Model):
    post = models.ForeignKey('blog.Post', on_delete=models.CASCADE, related_name='comments')
    author = models.CharField(max_length=200)
    created_date = models.DateTimeField(default=timezone.now)
    text = models.TextField()

    def __str__(self):
        return self.text

forms.py

from django import forms
from .models import Post, Comment


class PostForm(forms.ModelForm):
    class Meta:
        model = Post
        fields = ('title', 'text')


class CommentForm(forms.ModelForm):
    class Meta:
        model = Comment
        fields = ('author', 'text',)

views.py

from django.contrib.auth.decorators import login_required

            post.author = request.user
            post.save()
            return redirect('post_detail', pk=post.pk)

    else:

        form = PostForm()
        stuff_for_frontend = {'form': form}
    return render(request, 'blog/post_edit.html', stuff_for_frontend)

    post = get_list_or_404(Post, pk=pk)
    if request.method == 'POST':

        # updating existing form

添加注释HTML

{% extends 'blog/base.html' %}
{% block title %} Add Comment {% endblock %}
{% block content %}
<h1>New Comment</h1>
<form method="POST" class="post-form-blog">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit" class="save btn btn-default">Post</button>
</form>
{% endblock %}

我想你把这行的两个项目弄混了：

return render(request, 'blog/add_comment_to_post.html', {form: 'form'})

应该是

return render(request, 'blog/add_comment_to_post.html', {'form': form})
