Question

I’m uisng django.contrib.auth for authentication. The User mode has a custom profile model called Personnel. Personnel is linked to another table called Company.

class Personnel(models.Model):
    """
    Model for storing the personnel information
    """
    user = models.OneToOneField(
        User
    )
    company = models.ForeignKey(
        Company, null=False, verbose_name="Company"
    )

class Company(models.Model):
    """
    Model for storing the company information.
    """
    company_name = models.CharField(
        null=False, max_length=200, verbose_name="Company Name"
    )

• Once the user is authenticated. How can i fetch the company for a user? Something like request.user....

• In the view, I can access the request but if I need to access the request variable in my form and my model, do I need to pass the request variable to the form/model or is there any way to access it? This is because when I’m storing information for a particular Company, it should be the company to which that Personnel belongs to.

You should be able to access the company through request.user.get_profile().company. See the django documentation.

You cannot access request directly in a form, as the form could instantiated somewhere else too, not only in a view where no request object exists. You could pass the current user to the form when you initialize it (remember it makes more sense to pass the user not the request, so you can use it without a request as well).

class MyForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        self.user = kwargs.pop('user')
        super(MyForm, self).__init__(*args, **kwargs)

# in you view
form = MyForm(user=request.user)
