suggestion to add a argument 'methods=...' to app.route()

[ockan]

if render a form with 'GET', then receive form data with 'POST',
and serve the form with CSRF protection, no way to apply '@csrf_protect'.
if added a argument 'methods=...' to app.route(), we can

@auth.route("/login", methods='GET')
@render("auth/login.html")
async def login(request, response, **server):        
        return {'csrf_token': get_csrf_token(request)}

@auth.route("/login", methods='POST')
@csrf_protect
async def login_post(request, response, **server):
         data = request.form()
         ...

[nggit]

Doesn't CBV work?

@auth.route("/login")
class LoginView:
    @render("auth/login.html")
    async def get(self, request, response, **server):        
        return {'csrf_token': get_csrf_token(request)}

    @csrf_protect
    async def post(self, request, response, **server):
        data = await request.form()

(I used Session and Tremolo-login)

How did you do it? Any simple code that trigger that error?

[nggit]

Nevermind. I see the issue with just simple CBV + tremolo-login. Released v0.4.18 with the fix: #372
