Linking button to new page in Django not working

I have created an update view and am trying to link it to my form but the button linking doesn't seem to be working at all

urls.py

path('uploadupdate/<int:upload_id>', UploadUpdate.as_view(), name='uploadupdate'),

template: 

{% load static %}
<!DOCTYPE html>
<html>
<head>
<title>Manage uploads</title>
<link rel="stylesheet" href="{% static 'studyadmin/manageuploads_css.css' %}">
</head>

<body>
<table >
<tr class="main_row"> 
<th> Upload Name </th>
<th> Author Name </th>
<th> Type </th>
<th> Date </th>
<th> Edit </th>
<th>Edit Tags</th>

</tr>
<form >
{% csrf_token %}
{% for uploads in uploads %} <!-- shows all contents -->
<tr>
    <th> {{ uploads.title}} </th>
    <th> {{ uploads.author }} </th>
    <th> {{ uploads.upload_type }} </th>
    <th> {{ uploads.date_posted|date:"d M, Y"  }} </th>

    <th> <button href="{% url 'uploadupdate' uploads.upload_id  %}" type="submit" class="edit" formmethod="POST">Edit</button>  </th>
    <th> <button href="#" type="submit" class="edittags" formmethod="POST" >Edit tags</button>  </th>

{% endfor %}
</form>
</table>
</body>
</html>

views.py

class UploadUpdate(UpdateView):
form_class = UploadEditForm
template_name = 'studyadmin/upload_update_form.html'
queryset = Uploads.objects.all()

def get_object(self, queryset=None):
    obj = Uploads.objects.get(upload_id=self.kwargs['upload_id'])
    print(obj)
    return obj

def form_valid(self, form):
    upload = form.save(commit=False)
    upload.save()
    return redirect('/manageupload/')

I added the relevant code, I feel like its a small error but I can't seem to identify it since I'm very new to Django, any help would be appreciated!

You should refer to your app to use that URL because Django doesn't know to which app your URL name belongs to by default. So it'd be something like <button href="{% url 'appname:uploadupdate' uploads.upload_id %}" type="submit" class="edit" formmethod="POST">Edit</button>. Of course make sure that your project's URL Configuration includes your app's URLs. Hope it helps.

UPDATE

From the Django Documentation: 

...
class ContactView(FormView):
    template_name = 'contact.html'
    form_class = ContactForm
    success_url = '/thanks/'

    def form_valid(self, form):
        form.send_email()
        return super().form_valid(form)

Notes:

  • FormView inherits TemplateResponseMixin so template_name can be used here.

  • The default implementation for form_valid() simply redirects to the success_url.

So you should edit your View.

dont do this in your forms , Use it for getting the Fields from the models and the view allows you to connect your forms directly with your page you can directly print our data in a page so there is an example :

My models i have Question and ansewer attribute :

------ models.py ------

class Question_cours(models.Model):
    quest = models.CharField(max_length= 200 ) ---> question 
    rep = models.CharField(max_length = 20)  ----> answer 

--------- forms.py --------
class Form_question(forms.Form): /// important to make the same name fields 
        quest = forms.CharField()
        rep = forms.CharField()



 -------- view.py ----------


#-----------------------------------------------------------------------------
def add_question_cours(request):
    form = Form_question()
    if request.method == "POST":
        form = Form_question(request.POST)

    if form.is_valid() :
        Question_cours.objects.create(**form.cleaned_data)
    else : 
        print(form.errors)

    return render(request , 'bootstrap/add_question.html',context)
#------------------------------------------------------------------------------

-----------urls.py------------

  path('dfsdf',views.add_question_cours,name='add_question')

-----------------add_question.html----------

<form method="POST">{% csrf_token %}
<div class ="form-group">
{{ form.as_p}}
</div>

<button type =" submit" class="btn btn-danger ">
<i class ="fa fa-plus"></i>
</button>
