Form saves an empty row in the database

Using Django

Hello,

I have a simple “newsletter” signup form. It is defined as below:

The model is created like this:

class Subscriber(models.Model):

    email = models.EmailField(max_length=254)

    def __str__(self):

        return self.email

This is the form to subscribe:

                    <form action="" id="newsletterForm" method="post" role="form">
                        {% csrf_token %}
                        <input type="email" name="email" required><input type="submit" value="Subscribe">
                    </form>

This is the AJAX code to submit the data:

<script>

            $('#newsletterForm').submit(function(e){

                e.preventDefault()

                $.ajax({

                    type : "POST",

                    url : "/subscribe/",

                    data : {

                        subscriber_email : $('#email').val(),

                        csrfmiddlewaretoken : '{{ csrf_token }}',

                        datatype : "json",

                    },

                    success: function(){

                        alert('Success')

                    },

                    failure: function(){

                        alert('Error')

                    },

                });

            });

        </script>

And this is the function to save the data:

def subscribe(request):

    if request.is_ajax():

        subscriber_email = request.POST.get('subscriber_email')

        subscriber = Subscriber(email = subscriber_email)

        subscriber.save()

        response = {}

        return JsonResponse(response)

Everything works fine, except that I see new “empty” row in the database. Email address is blank?

I’d first verify that your jQuery selector is finding the right object - I kinda have the feeling it’s not. Use your browser’s developer tools to see the html being rendered, and then verify that your selector is correct.
