Doubt About the logged in user

Question

I’ve been put on hold for lack of work opportunity in my region. Now I’ve been invited to participate in a project and I’ve come across a problem that for me is complicated.

I need to start a field with the group name and/or 'unit' this is the name of the field I created, to which the logged-in user belongs, I created a class to define and this 'unit' and I’m trying to rescue in my form, porblem aé que ta voltar vazio initially concei cirando a function now and finally a class. the code is now giving result that is a Quary/Property type in capsule or returns empty when I use the class, my code was like this:

I am using Python3 and Django3

py.models

class Employee(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    unidade = models.CharField(max_length=100)

    def __str__(self):
        return self.unidade

Forms.py

class get_origem(Employee):

    def user_logado(slef):
        return slef.user.is_authenticated()

    def get_origem(self, user_logado):
        usuario = User.objects.get(username=user_logado)
        grupo_unidade = usuario.employee.unidade

        if grupo_unidade == user_logado:
            self.grupo_unidade

        else:
            self.grupo_unidade = 'NAO PERTENCE AO GRUPO'

            return self.grupo_unidade

        return self.grupo_unidade

class Cadastro_Unico_Add_Form(ModelForm):

    def __init__(self, *args, **kwargs):
        super(Cadastro_Unico_Add_Form, self).__init__(*args, **kwargs)
        self.fields['hospital_de_origem'].initial = get_origem

doubt is how to make the result return the logged user group or unit.

the other way I tried was this:

@property
def user_logado():
    return request.user.is_authenticated()

@user_logado.getter
def get_origem():
    usuario = User.objects.get(username=user_logado)
    grupo_unidade = usuario.employee.unidade

    if usuario == get_origem:
        grupo_unidade

    else:
        grupo_unidade = 'NAO PERTENCE AO GRUPO'

    return grupo_unidade

That returns it to me: <property object at 0x7f2c84ddd470> which I believe is the encapsulated result.

Answer 1

There is a certain difficulty in accessing instances of request within Forms, there are several tricks to this.

Use the Django-globals library, which allows you to access the user and request from anywhere.

Django-globals

When to start the form:

from django_globals import global

class Cadastro_Unico_Add_Form(ModelForm):

    def __init__(self, *args, **kwargs):
        super(Cadastro_Unico_Add_Form, self).__init__(*args, **kwargs)
        self.fields['hospital_de_origem'].initial = global.user.employee.unidade

Simple and clean solution
