How to pass data from one view to another and then to the template?

Question

Django

You need to forward the user_filter and datas data from def login_view to def index_view, so that this data can then be transferred to home.html

def login_view(request, *args, **kwargs):
form = UserLoginForm(request.POST or None)
test = 'asdasdasd'
if form.is_valid():
    user_obj = form.cleaned_data.get('user_obj')
    login(request, user_obj)
    conn_string = "host='localhost' dbname='askue_rs_test' user='developer' password='developer'"
    conn = psycopg2.connect(conn_string)
    cursor = conn.cursor()
    user = str(user_obj)
    cursor.execute("SELECT filter_department FROM accounts_myuser WHERE username = %s", [user])
    user_filter = cursor.fetchall()
    elem = (str(user_filter).lstrip("[('").rstrip("\\',)]") + "%")
    print(elem)
    cursor.execute("SELECT filter_dep from test_data WHERE filter_dep LIKE %s", (elem,))
    datas = cursor.fetchall()
    #print(datas)
    return HttpResponseRedirect("/")
return render(request, "registration/login.html", {"form": form})

def indexView(request):
return render(request, 'home.html')
