Ne peut pas obtenir le formulaire modèle django pour transmettre des informations à la base de données - Stack Overflow

I’m trying to post data from my django model form to my database, but am not having any luck. I can create from the admin and display on the page, but can’t seem to pass my information correctly. The comment is linked to the school with a foreign key, which I know works. Here’s what I have for my models, views, and html.

models.py

from django.forms import ModelForm

class Comment(models.Model):
    school = models.ForeignKey(Schools)
    created = models.DateTimeField(auto_now_add=True)
    author = models.CharField(max_length=60)
    body = models.TextField()

class CommentForm(ModelForm):
    class Meta:
        model = Comment
        fields = ['author', 'body', 'school']

views.py

EDITED

I also added the comment object create, just as another thing to try.

from my_app.models import Comment, CommentForm

if request.method == 'POST':
    form = CommentForm(request.POST) # A form bound to the POST data
    if form.is_valid(): # All validation rules pass
        author = form.cleaned_data['author']
        body = form.cleaned_data['body']
        school = form.cleaned_data['school']
        form.save()
        content = Comment.objects.create(school = school, author = author, body = body)

I have tried many variations on this view, but have not had any luck yet.

html

<form action="/" method="POST">{% csrf_token %}
     <p>{{ form.body }}</p>
     <div id="submit"><input type="submit" value="Submit"></div>
</form>

A. You must specify either {{form.as_p}}, {{form.as_table}} or simply {{form}} instead of {{form.body}}. Check the docs for more details: https://docs.djangoproject.com/en/dev/topics/forms/

B. The cleaned_data require an attribute from the Comment class. So, change: body = form.cleaned_data['comment'] with body = form.cleaned_data['body']

C. Have fun with Django.

Edit

Move the if request.method == 'POST': inside a new method, i.e. register_comment:

def register_comment:
    if request.method == 'POST':
        form = CommentForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            author = form.cleaned_data['author']
            body = form.cleaned_data['body']
            school = form.cleaned_data['school']
            form.save()

Modify the urls.py:

urlpatters = patterns('',
    # Some others views here
    url(r'^new-comment/$', 'app_name.views.register_comment', name="new_comment"),
    # Maybe Some others views here
)
