如何在django中设置和获取会话变量?

I need to set a variable on session, when a user login happens. How can I do this?

当用户登录时，我需要在会话上设置一个变量。我该怎么做呢?

if request.user.is_authenticated():
profile = request.user.get_profile()
request.session['idempresa'] = profile.idempresa

My other question is in a form:

我的另一个问题是:

class PedidoItensForm(ModelForm):
class Meta:
    model = ItensPedido

def __init__(self, *args, **kwargs):
    profile = kwargs.pop('vUserProfile', None)
    super(PedidoItensForm, self).__init__(*args, **kwargs)

How can I get the "idempresa" value of session, to use in my queryset?

如何获得会话的“idempresa”值，以便在查询集中使用?
