Re: Form not being published

There is no problem in the code. Look again at the quote and typos in the form class. and do a trial with this view:

from django.shortcuts import render
from django.http import HttpResponseRedirect
from .forms import CommentForm


def my_view(request):
    if request.method == 'POST':
        form = CommentForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks/')
    else:
        form = CommentForm()
    return render(request, 'index.html', {'comment_form': form})

I am creating a website using Django. I'd like to give users the chance to comment on pictures they have posted. I have created a comment model and a comment form, and put the following code into the HTML document for the photo gallery:

<h3>Leave a comment</h3>
            <form method="post" style="margin-top: 1.3em;">
                {{ comment_form.as_p }}
                {% csrf_token %}
                <button type="submit" class="btn btn-primary  btn-lg">Submit</button>
            </form>

However, the form is not displaying - there is nothing between 'Leave a comment' and the submit button on the page. I don't understand this as my form in forms.py appears to be configured correctly:

class CommentForm(forms.ModelForm):
body = forms.CharField(help_text="What is your comment?", widget=forms.TextInput(attrs={'size': '1000'}),
                       required=True)

class Meta:
    model = Comment
    fields = ('body',)
def as_p(self):
    # Returns this form rendered as HTML <p>s.
    return self._html_output(
        normal_row='<p%(help_text)s<p></p>%(field)s</p>',
        error_row='%s',
        row_ender='</p>',
        help_text_html=' <span class="helptext">%s</span>',
        errors_on_separate_row=True)`

So does my model in models.py:

    class Comment(models.Model):
COMMENT_MAX_LENGTH = 1000
image = models.ForeignKey(Picture, on_delete=models.CASCADE, related_name="comments")
user = models.ForeignKey(UserProfile, on_delete=models.CASCADE)
body = models.TextField(max_length=COMMENT_MAX_LENGTH)
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)

When I go into the source code on the site, it shows that the form is hidden. Also, when I change comment_form.as_p to something random, no error messages are generated. It's like something is causing Django to skip past that bit of code.

I'd really appreciate any suggestions anyone could please offer.

Thanks

Jeff
