(DJANGO) How to set current.username in author comment section - django

Question

I have Comment model in my Django app.
I want to make comment author to be current registered author, not another registered account.
Here is screenshot, I can choose user2 account to post the comment, but currently I'm on user1 account.
Here is my Django Comment model:
class Comment(models.Model):
post = models.ForeignKey(Post,on_delete=models.CASCADE,related_name='comments')
name = models.ForeignKey(User, on_delete=models.CASCADE)
email = models.EmailField()
body = models.TextField()
created_on = models.DateTimeField(auto_now_add=True)
active = models.BooleanField(default=False)
class Meta:
ordering = ['created_on']
def __str__(self):
return 'Comment {} by {}'.format(self.body, self.name)
And some code from html form:
<article class="media content-section">
<div class="media-body">
<!-- comments -->
{% if comments.count == 1 %}
<h2>{{ comments.count }} comment</h2>
{% else %}
<h2>{{ comments.count }} comments</h2>
{% endif %}
{% for comment in comments %}
<div class="comments" style="padding: 10px;">
<p class="font-weight-bold">
{{ comment.name }}
<span class=" text-muted font-weight-normal">
{{ comment.created_on }}
</span>
</p>
{{ comment.body | linebreaks }}
</div>
{% endfor %}
{% if new_comment %}
<div class="alert alert-success" role="alert">
Your comment is awaiting moderation
</div>
{% else %}
<h3>Leave a comment</h3>
{% load crispy_forms_tags %}
<form method="post" style="margin-top: 1.3em;">
{{ comment_form | crispy }}
{% csrf_token %}
<button type="submit" class="btn btn-primary btn-lg">Submit</button>
</form>
{% endif %}
</div>
</article>
EDIT
view.py
def post_detail(request, slug):
template_name = 'blog/post_detail.html'
post = get_object_or_404(Post, slug=slug)
comments = post.comments.filter(active=True)
new_comment = None
# Comment posted
if request.method == 'POST':
comment_form = CommentForm(data=request.POST)
if comment_form.is_valid():
# Create Comment object but don't save to database yet
new_comment = comment_form.save(commit=False)
# Assign the current post to the comment
new_comment.post = post
# Save the comment to the database
new_comment.save()
else:
comment_form = CommentForm()
return render(request, template_name, {'posts': post,
'comments': comments,
'new_comment': new_comment,
'comment_form': comment_form})

You can make the field non-editable, by setting the editable=… parameter [Django-doc] to False. I furthermore advise to use user and not name, since it is a reference to the user object, not the name of the user:
class Comment(models.Model):
post = models.ForeignKey(Post,on_delete=models.CASCADE,related_name='comments')
user = models.ForeignKey(User, editable=False, on_delete=models.CASCADE)
email = models.EmailField()
body = models.TextField()
created_on = models.DateTimeField(auto_now_add=True)
active = models.BooleanField(default=False)
class Meta:
ordering = ['created_on']
def __str__(self):
return 'Comment {} by {}'.format(self.body, self.user)
Then in your view, when the form is valid, you set the instance.user of that form to the request.user:
from django.contrib.auth.decorators import login_required
#login_required
def add_comment(request, post_id):
# …
if request.method == 'POST':
form = CommentForm(request.POST, request.FILES)
if form.is_valid():
form.instance.user = request.user
# …
# …
# …

Well, there shouldn't be a choice of users. To identify user just use request.user in your view. I don't know how your view looks like, but you can set name like this:
name = request.user
# or if you're using classes:
name = self.request.user
