Django 1.7 | Comment Form With Blog Post

Question

I working on a blog using Django 1.7.

I want to include a comment form with each blog post but unsure how to do that.

Here is my code:

Models:

class Category(models.Model):
    name = models.CharField(max_length=128, unique=True)
    slug = models.SlugField(unique=True)

    def save(self, *args, **kwargs):
            self.slug = slugify(self.name)
            super(Category, self).save(*args, **kwargs)

    def __unicode__(self):
            return self.name

class Post(models.Model):
    title = models.CharField(max_length=100, unique=True)
    slug = models.SlugField(max_length=100, unique=True)
    body = models.TextField()
    posted = models.DateTimeField(db_index=True, auto_now_add=True)
    category = models.ForeignKey(Category)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.title)
        super(Post, self).save(*args, **kwargs)

    def __unicode__(self):
        return '%s' % self.title

class Comment (models.Model):
    comment_body = models.TextField()
    commented_on = models.DateTimeField(db_index=True,auto_now=True)
    commenter = models.ForeignKey(User)
    post = models.ForeignKey(Post)

    def __unicode__(self):
        return '%s' % self.comment_body

class Tag (models.Model):
    title = models.CharField(max_length=100, unique=True)
    slug = models.SlugField(max_length=100, unique=True)
    post = models.ManyToManyField(Post)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.title)
        super(Tag, self).save(*args, **kwargs)

    def __unicode__(self):
        return '%s' % self.title

Views:

def blog_post(request, blog_post_slug):
    post_detail = Post.objects.get(slug=blog_post_slug)
    comments = Comment.objects.filter(post=post_detail.id)
    tags = Tag.objects.filter(post=post_detail.id)
    context_dict = {'post': post_detail, 'slug': blog_post_slug, 'comments':comments, 'tags':tags}
    response = render(request,'blog/blog_post.html', context_dict)
    return response

Template:

{% extends 'base.html' %}

{% load staticfiles %}

{% block title %}{{ post.title }}{% endblock %}

{% block body_block %}
<div class="container">
    <div class="post-preview">
    {% if post %}
    <div>
        <h2>{{ post.title }}</h2>
        <small>{{ post.category }}</small>
        <p class="post-meta">{{ post.posted }}</p>
        <p>{{ post.body }}</p>
<h3>Comments</h3>
        {% if comments %}
        {% for comment in comments %}
       <h5> {{ comment.commenter | capfirst }}</h5>
          <p>  {{ comment.comment_body }}</p>
            <small>{{ comment.commented_on }}</small>
        <hr>
        {% endfor %}
        {% else %}
        <small>No comments Yet </small>
        {% endif %}

        <h3>Tags</h3>
        {% if tags %}
        {% for tag in tags %}
       <span> <a href="{% url 'blog:tag' tag.slug %}"> {{ tag.title }}</a>,</span>
        {% endfor %}
        {% else %}
        <small>Without Tags! </small>
        {% endif %}

    </div>
    {% else %}
    <strong>No such post</strong>
    {% endif %}
        </div>
    </div>
{% endblock %}

I am using form.py to generate forms but unsure what to do in this scenario.

I just want that viewer can submit his comments on the page of blog post.

(This is answer was probably based off the Django tutorials at djangoproject.com and maybe elsewhere)

You can simply define a form for commenting in form.py, make a new instance of it in your blog_post() function, and include the newly minted form in context_dict. Then in the template, use {{ thenameyougiveyourforminthecontext }} to include a simple version of the form.

Then, in the blog_post() method in views.py, handle the form's submission. The Django website (specifically this page) describes how to handle the form's submission. In the form handling, you can create a new Comment object with the dictionary entries in form.cleaned_data (assuming you have validated it using form.is_valid() first) and save it.

This is a very brief overview of how to do this. Please look at the url I linked to truly understand how to do this.
