A traceback:

TemplateNotFound: static/themes/default/login.html 

jestem absolutnie pewny, że istnieje login.html (static/themes/default/404.html). Dlaczego tak się dzieje?

Answer 1

Myślę, że nie powinieneś uprzedzać themesDir. Przekazujesz nazwę pliku tylko do kolb, a następnie zajrzysz do folderu o nazwie templates w odniesieniu do twojego pliku Pythona.

Answer 2

Umieszczasz szablon w niewłaściwym miejscu. Z dokumentacji Flask:

Kolba będzie szukać szablonów w folderze szablonów. Jeśli więc twoja aplikacja jest modułem, ten folder znajduje się obok tego modułu, jeśli jest to pakiet, który znajduje się w twoim pakiecie: Zobacz dokumentację, aby uzyskać więcej informacji: http://flask.pocoo.org/docs/quickstart/#rendering-templates
