Getting id of instance in form and save in it-CodePudding

I am building a Blog App and I am working on a feature in which A user can report comment so I created another model for storing reports so i am saving which comment is reported But I placed report form in detail view so report form will be below the comment in post detail page, In which I am not getting the comment id when reporting.

models.py

class Blog(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=1000)

class Comment(models.Model):
    commented_by = models.ForeignKey(User, on_delete=models.CASCADE)
    body = models.CharField(max_length=1000)

class ReportComment(models.Model):
    reported_by = models.ForeignKey(User, on_delete=models.CASCADE)
    reported_comment = models.ForeignKey(Comment, on_delete=models.CASCADE)
    text = models.CharField(max_length=1000)

views.py

def blog_detail_page(request, blog_id):
    post = get_object_or_404(Blog, pk=blog_id)

    if request.method == 'POST':
        reportform = CommentReportForm(data=request.POST)
        if FlagCommentForm.is_valid():
            form = reportform.save(commit=False)
            # Saving in this line
            flagForm.reported_comment = reportform.id
            form.reported_by = request.user
            form.save()
            return redirect('home')

    else:
        reportform = CommentReportForm()




    context = {'reportform':reportform, 'post':post}
    return render(request, 'blog_detail_page.html', context)

blog_detail_page.html


{{post.title}}


{% for comment in post.comment_set.all %}

{{comment.body}}


<div class="container">
    <form method="post" enctype="multipart/form-data">
        {% csrf_token %}
        <table>
        {{ reportform }}
        </table>
        <button type="submit">Save</button>
    </form>
</div>

{% endfor %}

What have I tried :-

I have also tried by using loop like :-

comments = post.comment_set.all()

    for com in comments:
        if request.method == 'POST':
            ......
            if reportform.is_valid():
            ....
            ......
            ......
            form.reported_by = com

But it always saved the first comment id.

Then I tried by request.POST method, Like :-

comment_ID = request.POST['comment_id']

But is showed MultiValueDictKeyError error.

I have tried many times But the id of comment is not saving with report instance.

Any help would be much Appreciated. Thank you

You will need to add the primary key of the comment to the form, or to the URL where you submit the form to. For example as a hidden form element:

<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    <input type="hidden" name="comment_id" value="{{ comment.pk }}">
    <table>
    {{ reportform }}
    </table>
    <button type="submit">Save</button>
</form>

An alternative is to make a URL where you report a comment to with:

urlpatterns = [
    path('comment/<int:comment_id>/report', some_view, name='report-comment')
]

then you can submit the form to that view with:

<form method="post" action="{% url 'report-comment' comment_id=comment.pk %}" enctype="multipart/form-data">
    {% csrf_token %}
    <table>
    {{ reportform }}
    </table>
    <button type="submit">Save</button>
</form>
