Ich verwende Flask-Security mit benutzerdefinierten Vorlagen für meine Anmeldeformulare. Ich habe mein Formular definiert, aber aus welchem Grund auch immer wird das Formular nicht an das Template übergeben. HierFormular nicht definiert mit Flask-Security
ist die Form Code
class LoginForm(FlaskForm):
email = TextField('Email Address', [
Required(message='Forgot your email address?')])
password = PasswordField('Password', [
Required(message='Must provide a password. ;-)')])
Hier wird der Template-Code
<form method="POST" action="." accept-charset="UTF-8" role="form">
{{ form.csrf_token }} {{ render_field(form.email, placeholder="Your Email Address", autofocus="") }} {{ render_field(form.password, placeholder="Password") }}
<div>
<label>
<input type="checkbox" name="remember" value="1"> Remember Me
</label>
<a role="button" href="">Forgot your password?</a><span class="clearfix"></span>
</div>
<button type="submit" name="submit">Sign in</button>
</form>
Hier ist der Code für den Login
@mod_auth.route('/signin/', methods=['GET', 'POST'])
def signin():
# If sign in form is submitted
form = LoginForm(request.form)
# Verify the sign in form
if form.validate_on_submit():
for user in User.objects(email=form.email.data):
if user and user.password == form.password.data:
login_user(user)
if not is_safe_url(next):
flash('Logging you in')
return flask.abort(400)
return redirect(next or ('/')
elif user:
flash('Wrong password')
else:
flash('could not find username')
return render_template("security/login_user.html", form=form)
Der Code funktioniert, wenn ich die Zeile entfernen in der Konfig
app.config['SECURITY_LOGIN_URL'] = '/auth/signin/'
Aber wenn diese Linie gibt es wirft es diesen Fehler

Irgendwelche Gedanken oder gar wäre toll helfen! Vielen Dank im Voraus.
Sie verwenden Flask-Security, warum beschäftigen Sie sich selbst mit Login? – stamaimer
@stamaimer Nun, ich sah, dass die Sicherheit Flaschen Login für Logins verwendet und ich habe nie etwas über die Anmeldung zu sehen, so ging ich zu Flashen Login und Setup etwas ähnelt ihrer Dokumentation. Wie sollte ich die Logins machen? – Kenton
Haben Sie schon mal den [quick start] (https://pythonhosted.org/Flask-Security/quickstart.html) von Flask-Security durchsucht? – stamaimer
