UPDATE ON DJANGO

Question

I’m a beginner in Django and I’m trying to crud, create, read and delete are working, but the update is not working. Please help me out. This is the page with the data listing:

<table class="table table-striped table-dark">
            <tr>
                <th>ID</th>
                <th>NOME</th>
                <th>CPF</th>
                <th>EMAIL</th>
                <th>SENHA</th>
            </tr>
        {% for dado in dados %}
            <tr>
                <td>{{ dado.id }}</td>
                <td>{{ dado.nome }}</td>
                <td>{{ dado.cpf }}</td>
                <td>{{ dado.email }}</td>
                <td>{{ dado.senha }}</td>
                <td><a href="{% url 'atualiza' dado.id %}"><button class="btn-primary">EDITAR</button></a></td>
                <td><a href="{% url 'delete' dado.id %}"><button class="btn-primary">EXCLUIR</button></a></td>
            </tr>
        {% endfor %}
        </table>

The url that redirects to the page with the form:

path('atualiza/<int:id>', views.atualiza, name='atualiza'),

The form:

<form action="." method="POST">
        {% csrf_token %}
        <h3>Insira os dados para alteraçao</h3>
        <input type="text" name="id" value="{{ id.id }}" placeholder="ID" disabled>
        <input type="text" name="nome" id="nome" value="{{ id.nome }}" placeholder="Nome">
        <input type="password" name="senha" id="senha" value="{{ id.senha }}" placeholder="Senha">
        <input type="text" name="email" id="email" value="{{ id.email }}" placeholder="Email">
        <button type="submit">ENVIAR</button>
    </form>

The view:

def atualiza(request, id):
    id = Login.objetos.get(id=id)
    update = Cadastro(request.POST, instance=id)
    if update.is_valid():
        nome = update.cleaned_data['nome']
        senha = update.cleaned_data['senha']
        email = update.cleaned_data['email']
        query = Login(nome=nome, senha=senha, email=email)
        query.save()
        return render(request, 'index.html')
    else:
        return render(request, 'update.html', {'id': id}, {'update': update})

When I click edit, it redirects to the page with the completed form, but when I click send the error PAGE NOT FOUND. Thank you for your cooperation.

In your form the action="." may be changing the url where the post is being made. Just try <form method="post">
