Django form not submitting or providing error messages

问题

When I submit my form, it doesn't post the form data and just reloads the form. It was working beforehand but I'm not sure what I've changed that doesn't make it work anymore. Posting the data through the admin still works fine.

The only 'error' message I can see is in the terminal: which can be seen here

It sends a get request instead of a post request as well. I've also tested it with removing the JS and bootstrap CDNs but the issue is still the same.

My code is below:

Here is my views.py

def create(request):
if request.method == 'POST':
    form = EventCreateForm(request.POST, request.FILES)
    if form.is_valid():.
        instance = form.save(commit=False)
        instance.author = request.user
        instance.save()
        instance.save_m2m()
        return redirect('event:home')
else:
    form = EventCreateForm()
return render(request, 'event/create.html', {'form': form})

create.html

{% extends "base.html" %}

{% load crispy_forms_tags %}


{% block content %}

{{ form.media }}
<div class="container-fluid">
    <div class="col-md-4">
        <div class="page-header">
            <p> Create an event!</p>
        </div>
        <form  method="post" action="" enctype="multipart/form-data">
                {% csrf_token %}
            {{ form | crispy}}

            <button type="submit">Submit</button>
            <br>
            <br>
        </form>
    </div>
</div>



{% endblock %}

Thanks everyone in advance, All help will be greatly appreciated!

You may have deleted your action. Try adding the url back?

  <form  method="post" action="{% url "event:create" %}" enctype="multipart/form-data">
