Send template data to database

Question

I am facing a problem that in Django, in which my form cannot be validated, therefore, does not enter the data in the database. I want the user to have the option of adding a teacher. The structure of the form is ok, but it’s as if the request didn’t even get done. I’ve tried it in many ways and none of it has served. Follow the code below.

File views.py:

def adiciona_professor(request):
    form = AdicionaProfessor()

    if request.method == 'POST':
        form = AdicionaProfessor(request.POST)

        if form.is_valid():
            nome = form.cleaned_data['nomecompleto_professor']
            email = form.cleaned_data['email_professor']
            cpf = form.cleaned_data['cpf']
            salvando = Professor(nomecompleto_professor=nome, email_professor=email, cpf=cpf)
            salvando.save()

    return render(request, 'evento_detalhe.html', locals())

Forms.py file:

class AdicionaProfessor(forms.ModelForm):

   class Meta:
       model = Professor
       fields = ('nomecompleto_professor', 'email_professor', 'cpf', )

template:

<div class="card">
                <div class="card-header" style="background: linear-gradient(90deg,#9cd116, #0AF6AE); font-weight: 100;">
                    <button class="btn btn-link" data-target="#collapse" data-toggle="collapse" style="color: #0b2e13; font-size: 1.2rem">
                       Adicionar professor
                    </button>
                </div>


                <!--
                  * No bloco abaixo, constam as informações dos cards
                -->
                <div class="container">
                    <div class="collapse" id="collapse">
                    <div class="card-body">
                        <form action="" method="POST">
                            {% csrf_token %}
                            {{ form.as_p }}
                            <div class="form-group">
                                <label for="exampleInputName1">Nome Completo</label>
                                <input type="text" class="form-control" id="exampleInputName1">{{formulario}}
                            </div>

                            <div class="form-group">
                                <label for="exampleInputEmail1">Endereço de email</label>
                                <input type="email" class="form-control" id="exampleInputEmail1" aria-describedby="emailHelp" placeholder="Seu email" {{email}}
                            </div>

                             <div class="form-group">
                                <label for="exampleInputCPF">CPF</label>
                                <input type="text" class="form-control" id="exampleInputCPF" aria-describedby="emailHelp"{{cpf}}>
                            </div>

                            <input type="submit" class="btn btn-default" value="Cadastrar">
                        </form>
                    </div>
                    </div>
                </div>
            </div>

I left a print('Chegou') to see if the forms would even arrive at the form.is_valid(), but it wasn’t enough.

I thank you for your attention!!

Answer 1

I would make the view a little different. I believe the problem is there.

def adiciona_professor(request):
    if request.method == 'POST':
        form = AdicionaProfessor(request.POST)

        if form.is_valid():
            professor = form.save(commit=False)
            professor.nomecompleto_professor = form.cleaned_data['nomecompleto_professor']
            professor.email_professor = form.cleaned_data['email_professor']
            professor.cpf = form.cleaned_data['cpf']
            professor.save()
    else:
        form = AdicionaProfessor()

    return render(request, 'evento_detalhe.html', locals())

Answer 2

if request.method == 'POST':
        form = AdicionaProfessor(request.POST)

You say your method apparently doesn’t even go through form.is_valid() most probably because the method that the view receive is not a string POST and as there is no E-is, nothing is done.

at first, for you to understand what happens put something like this:

print(request.method)
if request.method == 'POST':
    form = AdicionaProfessor(request.POST)
    ...
else
    print(f'o trecho {request.method} está sendo executado no else'}

if you can see in the console the prints means that you are not actually going through the first conditional, then a solution is:

print(request.method)
if str(request.method) == 'POST':
    form = AdicionaProfessor(request.POST)
    ... # todo o resto do código aqui
else
    print(f'o {request.method} está sendo executado no else'}

turns the request into a string that probably the code will pass in the snippet

Function based views

  def adiciona_professor(request):
        form = AdicionaProfessor(request.POST or None) #post ou None
        if str(request.method) == 'POST': # comparando com uma string
            if form.is_valid():   # verifica se esta okay
                nome = form.cleaned_data['nomecompleto_professor']
                email = form.cleaned_data['email_professor']
                cpf = form.cleaned_data['cpf']
               #salvar
                messages.success(request,"tarefa concluida!")
                form = ContatoForms()
            else:
                messages.error(request,"Erro!")
    
        context ={"form":form}
        return render(request, "evento_detalhe.html", context)

class Based views, simplifies much more than function
