Getting NoReverseMatch error.

Using Django Templates & Frontend
1

First of all, I couldn’t figure out in which topic to post this issue. But I’m getting error in an HTML page, so here we go.
I’m implementing a Comment feature under User’s post in a Twitter clone Django project I’m making. I’ve created some files such as CommentForm in forms.py, Comment() in views.py, Comment model in models.py & tweet_comment.html page that’ll render page for commenting. I can’t quite figure out where it went wrong. Here are code snippets for same.

forms.py:

# For displaying Comment form 
class CommentForm(forms.ModelForm):
    body = forms.CharField(required=True,
                              widget=forms.widgets.Textarea(
                                  attrs={
                                      'placeholder':'Post your reply...',
                                      'class':'form-control',
                                      'style':'height: 150px; border-color: #484848;',
                                  }
                              ),
                              label=''
                            )
    class Meta:
        model = Comment
        fields = ['content',]

models.py:

# Create Comment model
class Comment(models.Model):
    user = models.ForeignKey(User, related_name='user', on_delete = models.CASCADE)
    tweet = models.ForeignKey(Tweet,related_name = 'comments', on_delete = models.CASCADE)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add = True)

    def __str__(self):
        return '%s - %s' % (self.tweet.user, self.tweet)

views.py:

# Handling Comment under post
def tweet_comment(request, pk):
    if request.user.is_authenticated:
        tweet = Tweet.objects.get(id = pk)
        if request.method == 'POST':
            form = CommentForm(request.POST)
            if form.is_valid():
                comment = form.save(commit = False)
                comment.user = request.user
                comment.tweet = tweet
                comment.save()
                tweet.comment_count += 1
                tweet.save()
                return redirect(request.META.get('HTTP-REFERER'), id = pk)
        else:
            form = CommentForm()
        return render(request, 'tweet_comment.html', {'form':form})
    else:
        messages.success(request, ('You must login to proceed.'))
        return redirect('home')

& finally, tweet_comment.html:

<div class="col-sm-10">
                                {{ tweet.body }} <br />
                                <small class="text-muted">
                                    ({{ tweet.created_at }}) By
                                    <a href="{% url 'profile' tweet.user.profile.id %}">@{{tweet.user.username}}</a>
                                    - {{ tweet.number_of_likes }} Likes -
                                    {% if user in tweet.likes.all %}
                                    <a href="{% url 'tweet_like' tweet.id %}">
                                        <i class="bi bi-heart-fill"
                                            style="color: crimson; -webkit-text-stroke: 1px;"></i>
                                    </a>
                                    {% else %}
                                    <a href="{% url 'tweet_like' tweet.id %}">
                                        <i class="bi bi-heart" style="color: crimson; -webkit-text-stroke: 1px;"></i>
                                    </a>
                                    {% endif %}
                                </small>
                            </div>

I’m getting NoReverseMatch error at {% url ‘profile’ tweet.user.profile.id %} in above HTML page. I double checked urls.py file, but no issue there. Surprisingly it works as intended in admin area.

Your tweet_comment.html template is referencing a variable named tweet, but your view does not pass a variable by that name in the context when you’re rendering the templates:
